The Real Truth about Low Carb…

Posted on by
1

Hi & Welcome Back!!

There seems to be a real lack of consensus as to what low carb means in a food  / diet choice..

For many people the term low carb means ‘old’ style Atkins  where the perception is that you ate nothing but fatty meats, cheese and eggs. (this of course was not true – the ‘old’ Atkins was more severe in terms of carb intake than the later versions, but all most folk know about the Atkins diet is the severe carb reduction of the initial 2 week dial in phase) For others low carbs means carbs making up less than 60% of your daily food intake. For still others it means aiming for no more than 20% of your food coming from carbs.

It is confusing – especially when diets that advocate a 40 / 30  / 30 split amongst the macronutrients is called ‘low’ carb when it patently is not.

For me Low carb is a misnomer and confusing – what we should be eating is as close to NO PROCESSED Carbs as possible.

In terms of general health & well being, in terms of stimulating your metabolism I don’t recommend low carb. Carbs are great! They are your body’s preferred fuel source after all.

But… and it is a big but…it depends upon the type of carbs that you choose to eat.

If you have been reading this blog for a while you’ll know that I am dead set against processed carbs. No ifs, no buts these have been proven time & again to wreak havoc on our bodies – especially when they are eaten like is predominant in the western lifestyle. The effect they have on your hormones (especially insulin) on your body composition (fat storage anyone??) on your energy levels (Afternoon fades anyone??) and your general health verges on the deadly.

By Processed carbs I mean sugar (in all its forms), white flour, white rice, most pasta, sodas, fruit & vegetable juices, any food labelled ‘diet’ or Low Fat’, cakes, cookies & breads – if it comes in a box or your grandmother would not recognise it as food – it’s a processed carb. Processed carbs also stimulate your appetite, meaning that you have to fight cravings  for more food because the processed carbs are so nutrient sparse that your body triggers its hunger stimulants to try to get more of the nutrients that it needs.

Preferred carbs are those remain as close to the filed as possible – the classic fresh fruit The shaper we get from eating processed carbs...and vegetables (frozen too!!) are high in fibre, create a higher TEF (Thermic Effect of Food – ie our body burns calories just to process them!) and have vitamins & minerals. These are the real deal – most are low in calorie count and high in nutrients and frankly I believe that you should eat as much low or unprocessed carbs as you want to. The only caveat being that you should ensure that you eat a variety of carbs,. If all you eat is pears – you could put on body fat due to the way fructose is metabolised – fibre or not. But a variety of fruit & vege choices ensure that this type of potential effect doesn’t happen.

But the real secret to eating healthy carb is to ensure that you have some protein with every meal.

If I eat a plate of pasta I am hungry again in short order. If I eat a plate of steak and veges.  I am sated for hours to come. Carb type matters.

Eating 2000 calories of processed carbs will, I guarantee, ensure that you are hungry again in a short time and are causing large insulin spikes as your body tries to deal with the increase in blood sugars. This is what happens to most  people… once they start eating large portions of processed carbs like pasta, cereals, or rice it becomes hard to stop and even worse they want more an hour (or less) later!

Now if you were to eat the same 2000 calories as low or unprocessed carbs a couple of things would happen. Firstly the sheer bulk of this amount of unprocessed carbs would ensure that you did not feel hungry for hours and secondly this amount of unprocessed carbs would mean that you would have to eat more slowly and slow eating has been shown to beneficially affect both metabolism nutrient uptake and satiety.

What I have found that works best for me is to avoid as many processed carbs as possible, try to have some protein with every meal and eat as much unprocessed or low processed carbs like fruit & veges as I want.  This is not eating in the ‘old’ Atkins style, it just means reducing or avoiding cereals, grains & pasta products, refined sugars and diet or low fat dairy products as much as humanly possible.

I am not going into the Paleo / Hunter gather diet versus the Western diet here – but the way I find works best for me is closer to this than the Government approved, obesity inducing food pyramid. I honestly think that this is the healthiest way to eat.

All it takes is a little lateral thinking – eat your burger without the bun, have your eggs without toast for breakfast, drink water instead of fruit juice have a sald instead of rice and os on. Try it – you will feel better, your energy levels will rise and like as not your fat will begin to decrease. Cool!

So the message is not to eat low carb, but eat low or no processed carbs as much as possible. Trust me your body will thank you for it!!

Be well. Don’t forget to lik us or Tweet…

8 Exercises, 7 Ways & 8 Foods to boost your Metabolism

Posted on by

Hi & Welcome back!!

This week I want to give you some specific foods, exercises and techniques for boosting your metabolism. As you know a faster metabolism means a leaner body and less body fat. You also know that in order to fit healthy & lean you need to use a combination of diet, exercise and lifestyle to achieve this.

Exercise:

The best format to use when exercising as I have discussed in earlier posts is HIIT (High Intensity Interval Training). The best way to use utilise this training protocol is to do what is called Metabolic Resistance Training which is a mix of resistance and cardio training. You do this by creating a cycle or chain of exercises that are performed as a circuit for a set number of rounds.

A good basic bodyweight chain is:

  • Push ups
  • Squats
  • Chin ups

Still a killer metabolic booster…

Run through this chain 3 – 5 times with 2 minutes rest between each round and you will raise your metabolism for hours to come. However this is a format, a protocol that gives results.

In terms of actual exercises to pick…Overall the best ones to use are those which use a lot of muscle (ie compound exercises) and create a high metabolic cost. So the list below is my picks for the best overall metabolism boosting exercises. It is not exhaustive nor is it meant to imply that you would do a workout that uses all of these exercises. Instead you can take a couple of these and combine them into a circuit and get the most bangs for your metabolic buck that way….

1.       Deadlifts

2.       Chin / Pull ups

3.       Squats

4.       Push ups

5.       Burpees

6.       Jumping Jacks

7.       Weighted Box Step ups

8.       Push presses

7 Ways to Fire Up Your Metabolism

Sometimes the smallest things—like getting more protein in the morning or enough rest at night—can lead to the biggest weight loss surprises.

Don’t skip breakfast.

Eating lean protein along with some complex carbs in the morning will get your metabolism revved up for the day ahead. Protein from eggs will help stabilize your blood sugar, make you feel fuller, and keep you from overeating later in the day.

Get your beauty rest.

Human growth hormone works directly on cells to increase your metabolic rate by 15 to 20 percent and can only be produced during the hours of deep sleep. So make sure you get a good night’s sleep!

Eat Whole Foods

At mealtimes, try consuming lean proteins from beef, lamb chicken or fish along with low GI complex carbohydrates from fruits and veggies. Eating this way kills cravings, enables you to feel full, and helps you avoid the downsides of sugars and their insulin spiking effects. This magical combination will speed up your metabolic rate as food is transformed into usable nutrients. Food not only provides fuel for your body, but it also provides specific instructions for your metabolism.

Eat Often

Every time you eat you increase your metabolism, the more often the more your metabolism boosts. Grazing all day is okay but can be difficult to manage. Try to eat 5 or 6 protein containing smaller meals to get more boosts in your metabolism!

 

Build Lean Protein Into Every Meal

Your body has to work much harder to break down protein – it increases your metabolism by increasing the Thermic Effect of Food. Adding protein to every snack and meal will increase your metabolism boost.

Avoid Highly Processed Foods

Check foods that have a label closely for the various types of sugar (Maltodextrin, sucrose, fructose, lactose, sucrose etc etc) High Fructose Corn Syrup and Hydrogenated Oils (Trans fats). These ingredients wreak havoc on your metabolism, generally lack fibre and don’t do a thing for your health.

Don’t Eat Carbs or Fat Just Before Bed

Instead have a protein shake (made with casein if possible as it is absorbed more slowly) as this will provide plenty of fuel for your body to use for repair & renewal while you sleep. Eating carbs or fat within 2 hours of going to bed however increases the chances of them being stored as fat.

8 Foods to Boost Your Metabolism

You know if you look over the magazines while you are waiting in the supermarket queue you’ll see endless headlines about the latest ‘super food.’ There seems to be one every week promising to melt those pounds away while you do whatever you want.

Often a good food is marketed with an emphasis more on people’s fears than any real effect it has. (Look at Acai berries – great for vitamin C, terrific source of antioxidants but not a miracle for fat loss…)

Unfortunately such foods with those wanted effects do not exist.

Without regular challenging exercise, a metabolic enhancing meal plan and a decent night’s sleep, your metabolic rate is not going to do anything except to stay sluggish.

The good news is that there are a number of things you can eat that will stimulate your metabolism. Even better all of these foods are delicious and nutritious.

Here are eight of my favourites:

  1. Fish.If you are a regular reader of this blog you’ll be familiar with the benefits of taking a fish oil supplement – simply put Omega 3 fatty acids are essential to your good health and to a faster metabolism. Not to mention their anti-inflammatory effects and other benefits. But Fish itself is a great source of protein. Protein increases your metabolism through increasing the Thermic Effect of Food (ie our body has to burn more calories to digest protein than it does for fat or carbs). In fact eating fish has been found to boost your calorie burn by as much as 400 calories a day.
  2. Dark green leafy vegetables. You know the ones – spinach, chard, kale, silverbeet, chicory, collard greens and so forth. These types of Veges are full of fibre (which increases your metabolism because of the extra calories needed to process it and ‘move’ it along. They are also full of vitamin A, vitamin C, loads of B group vitamins, calcium, and loads of other phytonutrients and minerals.  Most Veges are high in fibre, low in calories and boost your calorie burn, but nutritionally speaking the dark green leafy vegetables are the best overall.
  3. Tomatoes. Tomatoes contain high levels of the antioxidant lycopene, which is an anti-cancer phytonutrient (especially good for avoiding prostate cancer so the research suggests – so fellas need to eating a lot of tomato products) They also contain 3 acids in abundance – malic, citric and oxalic acid. These acids support your body’s kidney & liver functions which means that eating tomatoes helps your body eliminate waste and fat. Lastly like dark green leafy Veges, Tomatoes are a good fibre source.
  4. Blueberries and other berries & whole fruits. Whole fruits – not juices – contain lots of fibre, loads of vitamins and lots of antioxidants. One cup of blueberries only has about 80 calories, but it has 4 whole grams of fibre. This means that blueberries (like most whole fruits) increase the thermic effect of food by expending calories to deal with the fibre content. Blueberries are also believed to lower cholesterol and help to regulate blood pressure. Even better frozen berries show very little nutrient loss so you can have them & their benefits all year round!

  5. Whole grains. You’ll be getting the message by now – it terms of boosting your metabolism food can help through several mechanisms – through nutrients, through affect on hormones and through the mechanical cost of processing fibre. One of the best sources of fibre are whole grains. Personally I prefer to get my fibre from Veges & whole fruits but the fibre content of grains cannot be ignored and should be a part of your metabolism boosting food intake. However you need to check the food labels to ensure that the bread or cereal or pasta you are about to buy has whole grains as the main ingredient. Too many products proclaim themselves as whole grain but are chock full of sugars. Sugars that can take your metabolism in the wrong direction.

  6. Chillies, curries, and other spices. A constituent called capsaicin found in many hot peppers and other spices has the ability to fire up your metabolism while it fires up your mouth and makes you break a sweat. There are studies that show a 50 percent increase in metabolism for 3 hours after eating capsaicin. So keep your metabolism firing and add some flavour to your food by adding hot sauce, fresh chillies, a good Thai curry or capsicums to your meals. Spices are a simple to add ingredient to help kick your metabolism into a higher gear.

  7. Green tea. Yep – a lot of the hype is true – Green tea does increase your metabolism and your calorie-burning by up to four percent. It is also believed to assist in burning fats, reducing sugar cravings and works to inhibit the enzymes that slow digestion, thus raising metabolic rates. In addition to its metabolic properties, green tea is loaded with antioxidants and polyphenols, making it one of the most healthful beverage choices around.

  8. Ice water.Water is necessary for all your bodily processes, including the ones that control your metabolism. If you’re under hydrated, your body will underperform. Water also flushes out fat deposits and toxins.  Almost everyone from your Grandparents to the trainers on Biggest Loser to nutritionists the world over tells you to drink at least large glasses of water every day. The trick to using this to boost your metabolism is to make those 8 glasses ice water. If you drink ice water instead of room-temperature water, your body burns an extra nine calories per glass – not a lot but remember every bit helps when you are trying to recondition your metabolism. Drinking room-temperature water can burn roughly 16 calories per glass—ice water means a burn of 25 calories per glass.  So eight glasses of cold water a day can be responsible for burning 200 calories!

Remember, the right types of exercise, a good night’s sleep and smaller, evenly spaced meals are the formula for getting your metabolism rocking again…

How you can fix a Broken Metabolism Part 1

How can you fix a Broken Metabolism? Part 1

If you are more than 20lbs (10 KG) overweight the chances are your metabolism is slowing and may even, in terms of fat loss, be broken.

The next 4 Blog posts will look at the four main areas that not only affect fat loss but which we can influence to achieve a leaner, fitter body in the most efficient manner.

Let’s be clear everything we do, every process that takes place in our bodies, is an output of our metabolism. There are some areas where we can effect changes to it and the area we are most interested in is the area of fat loss.

Great way to recondition your metabolism…

Here is a quick overview of the various factors you need to strategically combine to recondition a flagging metabolism so that it is more efficient at creating fat loss…

  • Food types that:

o   Boost Metabolism

o   Blunt Metabolism

  • The Hormonal Affects of Food:

o   Fat Storage

o   Fat Sparing

o   Fat Burning

  • The Thermic Effect of Food:

o   Macronutrient ‘Burn rates’

o   Food timing

o   Meal Frequency

  • Exercise:

o   Weight bearing – lean = Higher metabolism

o   Cardio – work long or work hard can’t do both

o   Metabolic Circuits – HIIT, drive metabolism up and keep it up for up to 30 hours after

o   NEPA – non-exercise physical activity move more!!

Any attempt to shed body fat and to become leaner & fitter is at least 80% diet. But the diet

This’ll rev up your metabolism…

part of the equation is not as simple as the old fashioned ‘just cut calories’ approach. This is not only outmoded but leads to poor results. As we saw in an earlier post ( http://bodyshapeshiftersonline.com/?p=100)  a calorie is NOT just a calorie except as a way of measuring energy.

We now know that certain foods can increase our metabolism, these are Metabolic Fuels.

Metabolic Fuels tend to be low in sugar, lightly or un-processed and closer to nature than many of the foods you eat at the moment. These are nutrient dense foods that promote feelings of fullness, provide metabolism supporting vitamins & minerals and amino acids. They increase our metabolism by requiring more energy to process (see the upcoming part 3 for TEF), by providing essential vitamins, mineral, fatty acids and proteins for body repair & growth and by keeping blood sugar levels (see Part 2 – hormones) steady.

Metabolic Fuels:

  • Any lean type of lean protein – including whey protein powder
  • Eggs.
  • High fibre complex carbs like Oatmeal
  • Fibre rich vegetables like cauliflower, broccoli, bok choy, cabbage, and brussel sprouts.
  • Dark green leafy vegetables like Kale, spinach.
  • Tomatoes.
  • Blueberries and other whole fruits.
  • Cherries.
  • Beans – any type
  • Nuts – especially Walnuts
  • Omega 3 & 6 fatty acids from fish oil
  • Healthy Fats like Olive Oil, Coconut oil
  • Greek style Yogurt.
  • Green tea.
  • Ice water. It costs your body around 9 calories to warm up ice water to body temperature – 25 calories per glass instead of 16.
  • Dark Chocolate: Lots of antioxidants at the 70% or higher cocoa level. Just don’t eat the whole block you only need a square or 2.
This does as well….

Spicy Metabolic Fuels:

Chillies, curries, and other spices – many of these contain a substance called capsaicin. Capsaicin can fire up your metabolism (some studies have shown a 50 percent increase in metabolism for 3 hours after eating capsaicin), act as an anti-oxidant and assist in stabilising blood sugar.

Here are some of my favourite metabolic & flavour enhancing spices:

  • Cayenne pepper
  • Chilli powder
  • Black pepper
  • Turmeric
  • Cinnamon
  • Ginger
    • Garlic Coriander / Cilantro

 

This is not a complete list by any means but the rule of thumb here is the closer to nature a food is, the more beneficial it is for reconditioning your metabolism.

On the other side our culture is full of highly processed denatured, nutrient sparse foods that blunt & slow our metabolism.

These foods lack fibre, are quick to be processed by our bodies, convert easily to sugar and often need vitamins & minerals added back to them to give them some nutritional value after processing.

Food Like:

  • Sugars – fructose, sucrose, dextrose, maltodextrin, to name but a few varieties
  • White Flour & white flour products like white bread, cookies, & biscuits
  • White Rice, rice crackers
  • Noodles
  • Semolina
  • Most pastas
  • Soda Pops
  • Cakes & Baked Goods
  • Commercial Fruit Juices
  • Most commercial yoghurts – especially low fat varieties (this usually means high sugar!!)
  • Virtually any packaged product that screams ‘Low fat’

The rule of thumb here is if it contains ‘white carbs’ (think flour, sugar & rice) it is best

Years of a broken metabolism at work…

avoided or at least eaten sparingly. If it promises to be ‘low fat’ – check out the sugar content because high sugar is worse than saturated fat for your metabolism. If your Grandmother would not easily recognise it as food think twice.

Mum was right lots of leafy vegetables and fruit along with lean protein is the best way to eat.

Foods can also elicit a hormonal response from our bodies based upon calorie numbers and the quantities and types of macronutrient present. These responses can be either fat burning or fat storing.

Simply put look to move towarss food swith the fewest number of ingredients on the label. Generally fewer ingredieints means less processed and less processed means more nutrition and less calories…

Next time we’ll look at the Hormonal Affects of Food

  • The Hormonal Affects of Food:

o   Fat Storage

o   Fat Sparing

o   Fat Burning

I hope you found the information above of interest. We’ll be backnext week to look at Hormones & Fuel.

The Surprising Truth about Saturated Fats & their place in a Healthy Lifestyle.

Posted on by

The misconceptions and outright lies about saturated fat and your health.

Hi Welcome Back!!

As you know I believe that there is a mountain of evidence (growing larger daily) that shows that processed carbs are the underlying cause of obesity and that a simple way to drop body fat and shift your shape is to cut them out of your diet.

Surprisingly research says you should too...

A few people have written in and asked ‘What about saturated fat? Doesn’t it cause hear t attacks and obesity?’

Here is the first of several posts on the truth about saturated fat. What I have to tell you will surprise you. It may even make you angry.

For decades we’ve been told that saturated fat will clog up our arteries and kill us. Most health professionals will tell you that fat is bad for you, that it raises the bad cholesterol (LDL), causes obesity and is a major contributing factor to heart disease & stroke. The media also pushes this line and rolls out dietician and nutritionist one after the other who agree.

The trouble is that no-one has ever proved it.

You read that right – NO-ONE HAS EVER PROVED IT!

There is better proof for these than the Lipid hypothesis

What has become Politically Correct Nutrition is based on the assumption that we should reduce our intake of fats, particularly saturated fats from animal sources. Fats from animal sources also contain cholesterol, which is presented as the other main cause of heart disease and is seen as an evil part of the a ‘civilized’ diet.

I’m here to tell you that this is a false perception. And a deadly one.

Simply put saturated fat is a normal, natural part of the human diet and has been literally from the time the first Neanderthal took a bite of animal…

Fats are essential to our health – without them you would sicken & die.

Why?

Well fats from animal and vegetable sources:
• Act as a concentrated source of energy in the diet;
• They provide essential parts of the building blocks for cell membranes
• They provide a wide variety of hormones and hormone-like substances.
• They act as carries for all of the fat soluble vitamins like A, D, E,& K
• They assist with mineral absorption
• They are an essential part of the processes involved in converting carotenes into Vitamin A
• Fats slow down absorption of food if part of a meal so it takes longer for us to feel hunger again.
• Fats are a part of what keeps our skin in condition
• Fats are involved in…
You get the picture – fats are essential to our health.

The cause of this demonization of saturated fats is a thing called the ‘Lipid Hypothesis’. (fat theory).

Now according to this fat theory there is a direct relationship between the amount of saturated fat and cholesterol in someone’s diet and their incidence of coronary heart disease. This was proposed by a medical researcher in the 1953 whose name was Ancel Keys who believed that there was a connection between fat intake and mortality from heart attacks in 6 countries: Japan, Italy, England, Australia, Canada, and the USA.

His research has called the anti-fat tune for over 40 years...

What he reported was that the US had the highest heart attack rate and the highest fat intake whilst Japan had the lowest fat intake and the lowest rate of heart attacks. The other countries neatly fitted into the 2 extremes, again based on reported fat intake and heart attack incidence. Keys called this a ‘remarkable’ relationship and went public with the idea that eating fat causes heart attacks. He was quite a natural publicist and was soon on the cover of TIME gravely warning that people were ‘eating themselves to death’.

In 1970 he then said that new research had shown that it was not all fat, but rather the amount of animal fat eaten could be used as an accurate predictor of someone’s likelihood of suffering a heart attack. He also noted that there was a strong link between cholesterol and heart disease. His hypothesis was that the saturated fat derived from animals raised cholesterol and this lead to heart disease. Most Doctors and even the Heart Foundation believe this to this day – 40 years after the theory was proposed.

Thing is there are major flaws & problems with Keys & his research.
In numerous subsequent studies over the last 40 years his data and conclusions have been brought into question. For example the data he used to draw his conclusions came from only six countries – which represent only a small portion of the countries where data was available on fat consumption versus heart disease death rate.

When subsequent researches have gone back and used data from the same era, but from a greater range of countries, even with a bias towards the ‘western diet;’ they found that there was no link between fat consumption and heart disease deaths.

Read that again – NO LINK!!

So Keys’ conclusions were actually false.

Next is the fact that even in the 1950’s it was recognised that there were a number of factors that caused heart disease but Keys chose to consider only one potential factor – fat intake. He gave no consideration of other factors such as smoking rates, stress factors, sugar intake, exercise frequency etc etc.

Guess Keys forgot about these & heart disease...

It is unfortunate that his faulty research was coupled with a flair for promotion and the beginnings of the food processing industry because this confluence of factors has seen Keys study cited for over 5 decades as proof of the “fact” that saturated fat is bad for you.

There ain’t much in the way of facts here…

Since that time, numerous other studies have been conducted trying to link saturated fat intake to heart disease. The majority of these studies have failed to correlate ANY risk at all from saturated fat. A couple of them made feeble attempts at linking saturated fat to heart disease, however, it was later shown that in those studies, the data was flawed as well.

This is actually good for you...

I’ll be back with the Whys & Wherefores of the good things about saturated fats and how eating them can actually be better than good for your health…

Metabolism – What it is & How you can make it work for you Part 1

Posted on by
Reply

The next few posts on this blog will be all about giving you a solid understanding of what your metabolism is, what affects it and how you can make it work for you.

The information here will give you a better working knowledge of those parts of your metabolism that you exert some direct control over, those you can exert some indirect control over and those you just have to live with!

Having a fast metabolism means more than exercising...

If you have ever felt like you’re fighting a losing battle to shed pounds, in a sense you are.

Metabolism is NOT just about energy in versus energy out.

In our primitive past our bodies evolved so that we could store energy as fat in times of plenty (feasting) so that we are able to survive in times of scarcity. In these modern times we feast and then feast again without ever really enduring times of scarcity where food becomes rare and starvation looks likely. So this survival mechanism keeps storing energy as fat against hard times that frankly most modern humankind will never experience.

That creates problems for us because our bodies are basically fat storage machines. Very efficient ones.

The Body Shape Shifters philosophy is based around the idea of reconditioning your metabolism through a strategic mix of exercise, diet and hormone manipulation. A high metabolic rate means that we use the nutrients from our food more efficiently, maintain healthy body composition (lower fat and higher muscle levels) longer, feel better, think clearer and live healthier lives overall

What is Metabolism?

Beginning with birth and ending at death, our body receives the energy it needs to fuel itself through the processes of metabolism.

Yep - it can appear complex...

Metabolism is an umbrella term that covers the non-stop chemical processes that operate to keep our bodies functioning. Your Metabolism is primarily 2 things:

1)      The rate at which your body uses energy to support all of the basic functions that are essential to sustain your life,

2)      Plus all of the energy requirements for needed for additional activity and digestive processes.

Think of it this way – just being alive requires energy so when we talk about Metabolism it includes standing, sitting, sleeping, running, jumping, breathing, eating, digesting, having a beating heart, growing new cells, hair, skin, muscle and bone. So when we talk about our metabolic rate we are talking about the rate at which our bodies are burning the calories / kilojoules we have stored and that we get from food.

Your metabolism burns calories / kilojoules all the time, whether you’re just sitting on the couch or you’re jogging around the block. Even while we sleep our metabolism is working.

Every process that takes place in our body ultimately gets the energy to do so from the food we eat. The food we eat is broadly made up of Carbohydrates, Fats or Proteins with some micronutrients in the form of vitamins & minerals. (More detail on the effect that different nutrients have on our metabolism in later posts.) The amount of calories your body burns at any given time is regulated by your metabolism. In other words, it’s not just about burning up the food we eat, but about how the various nutrients from that food are used to help us maintain a healthy body.

There are two primary metabolic processes that take place in your body:

Catabolism – this is the breakdown of food components such as carbohydrates, proteins and fats into

No! Not that sort of anabolism!!

their simpler forms, where they are then used to create energy which can be turned into heat or burned up by your cells. This can also mean the breakdown of body tissue like muscle in the absence of other fuel sources. Catabolism is the destructive phase of metabolism, and the critical partner to anabolism, as they rely on each other to do their specific jobs. Digestion is a catabolic process that breaks your food down into smaller particles that can then be used in anabolism.

Generally characterised as ‘bad,’ catabolism is an essential part of our metabolic processes.

Anabolism – means growth or storage so energy is stored as glycogen in the liver & muscles, in fat cells (once the glycogen stores are full) or used to help build and repair structures of the body. It is most often associated with muscle growth. Anabolism is the constructive phase of metabolism, as it produces all of the substances needed in our body for it to grow, maintain and repair itself.

These two processes are carefully monitored by our body to make sure they remain in balance. However our diet, our environment and our type & amount of daily activity can all affect them both.

Ultimately our metabolism is controlled by hormones (think chemical messages that trigger processes) and by our nervous system. Hormonal problems, our physical environment and genetic disorders can all affect our metabolism. Whilst we cannot control our metabolism per se, we can make it work for us.

In part, Hormones determine how much of each of these you have...

Studies conducted by Spennewyn in 1990 found a number of strong correlations between lean mass and metabolism based on indirect calorimetry measurements. Spennewyn discovered that lean tissue in men and women required approximately 16 calories per pound per day. This means that once a person’s lean mass is known then it can be multiplied by 16 to reveal ball park daily caloric needs based on the activity level of the individual. This method has been used in many gyms, health clubs and dietician settings to determine daily caloric needs. It is not perfect.

Where is the energy used?

Energy expenditure for your body is roughly broken down like this:

  • Liver 27%
  • Brain 19%
  • Heart 7%
  • Kidneys 10%
  • Skeletal muscle 18%
  • Other organs 19%

To shift our shape by getting rid of fat we need to understand the ways & the speed with which we burn the calories from the food we eat. We cannot necessarily speed up all of your metabolic processes but we can make them more efficient.

Well that’s the basic stuff out of the way – next week we get into some terms to know and then the 4 components of your metabolism & how you can affect them for your benefit.

Be well.

My Gym Program to Shed Fat – Fast!!!

Posted on by

Welcome Back!!

Last time I listed 30 something reasons to get in shape if you are over 30 and this time I want to look at the use of exercise as a major component of getting into shape  – or staying there once you’re happy with how you look.

The first type of program uses barbells & dumbbells and pretty much needs a gym so you can access enough weight to really challenge yourself. If you are already set up at home so much the better….

But what if I don’t go to the gym I hear you ask? Don’t worry – I have info on how to use body weight workouts in the next blog post.

Not many of us can afford to set up a home gym with this much equipment

We all know that diet is 80 – 90% of fat loss and that you cannot out-train a poor one.

So let’s assume that you’ve reduced your calories and are eating nutrient dense but calorie sparse foods. That you are eating clean – lots of protein and low GI carbs, few processed foods, no transfats and you’ve come as close to eliminating High Fructose Corn Syrup from your diet as humanly possible. You’ve also added spices like cinnamon & capsicum to your diet, drink green tea and use protein shakes as a means to keep your body feeling full and also staying in positive nitrogen balance. In other words you’ve got your fat loss diet sorted.

Now we need to get the exercise part firing, this is one of my preferred routines.

Now as we have discussed in previous posts – once our bodies sense a cut in calories it immediately begins to preserve (and if possible) add to fat stores. It also begins to burn muscle for fuel once glycogen stores are depleted – result; a slower metabolism and more body fat.

You can combat this though – by convincing your body that it needs to maintain if not add to your muscle if it is to survive. And we do that by lifting heavy weights and then following this up with a Metabolic conditioning / HIIT style workout.

No more than hour is needed to get great results

The total workout should take no more than an hour with 30 minutes spent on the strength / muscle preservation side and the final 30 spent on reconditioning & firing up your metabolism with some HIIT circuits.

Your goal has to be to maintain lean muscle and to max strength when you are reducing calories. The best exercises to use for this are compound (ie multijoint) ones like Squats, Deadlifts, Overhead Presses and weighted Chin Ups. (You’ll note the absence of the bench press – this is deliberate as I & many others believe that it is not as effective as overhead presses, creates strength imbalances in the shoulder girdle and often causes shoulder injuries)

So in order to preserve your muscles and build strength you use this program:

  1. 1. Deadlifts paired with Overhead presses on Day 1
  2. 2. Squats paired with Pull ups (weighted if possible) on Day 2

The reason that pullups and deadlifts aren’t paired together is that they’re both challenging to your grip and will weaken it. A weak grip means that you can do fewer reps or use less weight so by splitting them apart your grip only gets ‘hit’ with 1 exercise each session. (Note – if you can’t do weighted chin ups don’t worry – do as many as you can in each set. Once you get strong enough to do 10 from ‘dead hang’ with good form then add some weight and drop your reps back to 3 or 4 and work back up)

On each day you do the following metabolic condition workout:

You WON'T be using any of these - they don't work!!

  1. 1. Dumbbell Squat and Presses
  2. 2. Jumping Jacks
  3. 3. Dumbbell Bench Step-ups with Bicep Curl (do reps for each side)
  4. 4. Squat Thrusts
  5. 5. Dumbbell Walking Lunges (do reps for each side)

Go through 10 – 15 reps of each exercise pausing only long enough to swap weights until you’ve completed one circuit. Rest long enough to get your breathing down ( 2-3 minutes) and repeat 3-5 times.

The goal of this style of training for the second 30 minutes of each workout is to get your metabolism really ramped up so that you create a strong EPOC and continue to burn fat as fuel for hours after the workout is done.

Execution:

Firstly warm up with some Jumping Jacks followed by walking lunges, then shoulder swings, some push ups and some body weight squats. Not a lot, just enough to get the blood flowing and the joints lubricated.

Then set up your barbells for the deadlift and the overhead press. Put enough weight on each bar so that you can only do 5 -6 fast reps of each exercise with good form.

Don't forget to warmup first

Speed is important as it engages more muscle fibres, fires up more mitochondria ( the fat burning furnaces in each cell) and builds more strength. Good form matters as injury will slow if not halt your progress. Always err on the side of caution.

Then do 3 – 4 sets in circuit fashion (3 reps of Deadlifts, rest long enough to get your breath back, then 3 reps of Overhead Press, rest long enough to get your breath back then back to Deadlifts again and repeat for 3-4 times)

That is the first part of the workout on day 1, next you move to part 2 which is the metabolic circuits.

For these you need to set up several sets of different dumbbells. You need different weights as you will be able to handle different ones depending upon the exercise. For example you can hold a larger weight for the walking lunges than you can curl on the step ups. Again aim for speed with good form.

Put your equipment back and go home and eat a meal high in protein, moderate carbs and low fat. Because you are trying to drop bodyfat you should NOT go the high carb route. That works when you are already lean and certainly enhances muscle growth, but if you are carrying body fat your metabolism is still primed to store carbs as fat…

Then you come back on day 2 and do the squats & Chin Ups followed by the same metabolic workout.

For best results, and if you are up to it you should workout 6 days a week, alternating Workout 1 with Workout 2.

Over a week it would look like this:

Day 1- Deadlifts & Overhead Presses + Metabolic Conditioning Exercises

Day 2- Squats & Chin Ups + Metabolic Conditioning Exercises

Day 3- Deadlifts & Overhead Presses + Metabolic Conditioning Exercises

Day 4- Squats & Chin Ups + Metabolic Conditioning Exercises

Day 5- Deadlifts & Overhead Presses + Metabolic Conditioning Exercises

Day 6- Squats & Chin Ups + Metabolic Conditioning Exercises

Day 7 – Rest

Follow this program for 6 weeks with a clean metabolism boosting diet and you’ll see great results. Make no mistake though – this is hard work and should be challenging!!

Results come to those who work at it!!

If however you are just starting out you should aim for working out 3 days a week with a 2 week program that looks like this:

Day 1- Deadlifts & Overhead Presses + Metabolic Conditioning Exercises

Day 2- Rest

Day 3- Squats & Chin Ups + Metabolic Conditioning Exercises

Day 4- Rest

Day 5- Deadlifts & Overhead Presses + Metabolic Conditioning Exercises

Day 6- Rest

Day 7 – Rest

Day 8- Squats & Chin Ups + Metabolic Conditioning Exercises

Day 9- Rest

Day 10- Deadlifts & Overhead Presses + Metabolic Conditioning Exercises

Day 11- Rest

Day 12- Squats & Chin Ups + Metabolic Conditioning Exercises

Day 13- Rest

Day 14- Rest

If you use the 14 day cycle aim to do it for at least 8 weeks then switch to the 6-days a week one foe another 4.

Well there you have it – follow this program with a clean diet and the fat will certainly disappear.

See next time when we’ll look at why bodyweight workouts can deliver excellent results – even without gym equipments.

Be well.

Insulin – not the bad guy we thought???

Posted on by
3

Hi & Welcome back!!

For years Insulin has been painted as the bad guy hormone – you know the one that takes blood sugar and then shunts it off to be stored as fat.

Thing is, this is only partially correct. The real issue for most of us in the Western world insulin resistance coupled with too many processed high GI carbs. In fact becoming more insulin senstive will help us lose fat, build muscle and have a more efficient metabolism.

Insulin Sensitive or Resistive??

Traditional Nutritionists & Dieticians, despite the mountains of research to the contrary,  all seem to believe that fat loss is as simple as subtracting X calories from your daily intake and Hey ! Presto! Instant 6 pack abs! Be nice if it was true and would fat loss a whole lot easier and Gyms & weight loss centres would rapidly be rolling out lean, athletic women & men.

Just imagine the world we would be living in if all it took was the application of some simple arithmitic applied to a total calorie count. <sigh> never going to happen.

Let’s not make any mistake here though – a pound of fat is still 3500 calories and to lose fat you still have to achieve some form of calorie deficit in order to do so. In fact no mater how hard you train you can’t outperform a bad diet – or one that overloads you with calories that you just don’t need.

But this is only a part of the overall strategy that we need to use to achieve our desired outcome –  a leaner body that LBN and has a revved up metabolism.

Part of this strategy is understanding the metabolic and hormonal effects of food and then using  these effects in a tactical plan to achieve our goals.

Insulin Sensitivity

The single most important hormone when it comes to body recomposition is – Insulin. Yep the ‘bad guy’. Y’see Insulin is the most anabolic(repair & growth) and anti-catabolic (tear down) hormone that we have.

Insulin improves amino acid uptake by muscle tissues initiating protein synthesis promoting growth & repair. It also acts to prevent amino acids (the building blocks of our bodies) whether from food or our hard earned muscle from being used as a reserve fuel source when calories are cut below what our body has become to view as the ‘norm.’

Trustworhty fat loss advice? I don't think so...

Insulin also has a ‘dark side – under the right conditions, it is also the most lipolytic (fat storing) hormone in the body, shuttling fatty acids and glucose to fat cells for fat storage.

A logical approach to fat loss is one that moves you to a low-carb diet that is used to reduce calories and at the same time minimise insulin release so you avoid fat storage. This is right on the money if you are overweight, have a low activity level and are likely insulin resistant (or well on the way to being so). This covers the majority of the population these days.

It is also the way to go if you are over 40, a Type II diabetic or suffering from Syndrome X. I agree except that I am NOT an advocate of low carbs, but an advocate of low processed carbs for fat loss.

However no hormone is completely bad and the above approach is an incomplete one. If you work out hard on a regular basis, create a calorie deficit whilst eating nutrient dense foods – then moderate amounts of insulin is a positive thing. Why?

Because  insulin helps your body to maintain muscle the leaner you get. So you can strip off fat and keep or build muscle. The key is the complete approach of training, diet and food types.

However if you are overweight, sick, obese, a sedentary worker on the slope to Type II then your diet should not be the same as for someone who is active, lean and nowhere near becoming a diabetic of any persuasion.

In utilising insulin’s positive side – one size does not fit all.

If your body is insulin sensitive then you can have a higher amount of carbs in your diet because you will get the anabolic effects of this hormone. Again my belief is that you should avoid as many processed carbs as possible, but if you have some and are Insulin sensitive the efects will less likely to go to fat storage.

All carbs but not much goodness here...

If your body is insulin resistant, then higher carbs will mean that suffer more of its’ lipolytic (fat storing) effects. Simply – high GI & processed carbs should be a muich smaller part of your diet if you are insulin resistant.

So if you want to recompose your body you need to look at ways to increase your insulin sensitvity and reduce your insulin resistance.  Becoming more Insulin ‘Sensitive’ as opposed to resistant should be a goal right up there with resistance training, metabloic conditioning and eating lots more protein.

So in addition to focussing on cuting out high GI processed carbs we need to looking at ways to improve our bodies ability to utise them & insulin more efficiently.

Some easy ways to improving your Insulin Sensitivity.

1. Avoid mixing  ‘White’ Carbs with HFCS

All carbs aren’t be bad. All grain based carbs require at least some processing before humans can eat them. White carbs (flour, pasta rice – even the ‘healthy’ brown varieties) by themselves are not fat inducing. But combining these starches with sugars – especially fructose, and particularly HFCS – is downright evil.

Google High Fructose Corn Syrup and you’ll see that many researchers are now condemning the use of this sweetener as the major cause behind the obesity epidemic in the Western world. Americans partake of over 60 pounds a year…

Millions of our Asian brothers & sisters eat one of the purest starches out there aa a dietary staple – rice. By pure low carb thinking they should be the fattest folk on Earth. They’re not and in fact it is only when the traditional high starch / low sugar ratio becomes high starch / high sugar do we see obesity & diabetes rates rise in Asian populations.

The number one cause of obesity in the USA - HFCS

Guess which form of sugar has the worst effect on ALL humans? Got it in one – fructose, particularly HFCS.

Fructose is metabolised & processed by our bodies differently from glucose. There are now a heap of studies that indicate that fructose, NOT glucose, is the main culprit in table sugar that causes insulin resistance.

In animal studies increased fructose intake produced insulin resistance, impaired glucose tolerance, high insulin levels, high triglycerides, increases in whole body inflammation and hypertension.

So to up your insulin sensitivity and to lower your insulin resistance – start by cutting out high fructose corn syrup, fructose sweeteners, sugar, sodas, processed fruit juices, fruit smoothies, and dried fruit. Then make sure that if you are having ‘white’ carbs ou are not mixing them with fructose – so watch cakes & cookie, pasta sauces and more. read your labels!!

Remember – never, ever combine white carbs with HFCS.

You can still eat 1-4 pieces of whole fruit a day is permissible – its fructose effects are ameliorated by the fibre (slows down digestion) and the presence of vitamins, minerals & antioxidants mean that fruit has more good than bad.

2. Increase your Omega 3’s

The ratio of your fatty acids is important to your overall health. We all know this. Just like we all know that our intake of Omega 6 is way higher than our intake of Omega 3 because of our use of canola oils etc etc.

Omega 3’s have been shown to improve insulin sensitivity and have a host of other beneficial health effects. Cut down on the polyunsaturated oils, increase the olive oil, eat cold water fish, grass fed beef, lamb & take a fish oil supplement.

3. Add some Spice

This is a natural way to improve your Insulin Sensitivity...

Cinnamon has been shown to increase insulin sensitivity when a couple of grams a day are added to your diet. Numerous studies have shown it improves glucose uptake by the cells.

Oh yeah – it has to be cinnamon powder – not pop tarts or cinnamon donuts…

4. Have some Green Tea

Metformin is a prescription glucose dispersal drug that is given to folk in the pre-curser and then the actual type II diabetes stages.  It is expensive, and in the 90’s a lot of bodybuilders were using it. Why – well the role of any glucose dispersal agent is to mimic the effect of insulin in insulin resistant folk.

The good news is that green tea is also a glucose dispersal agent. So drinking 3 -5 cups a day can actually help improve your insulin sensitivity. Even better green tea’s action shows a distinct inclination towards pushing carbs to muscle cells and not to fat cells.

Sounds about perfect to me – and you don’t need a prescription!

5. Ditch the trans fats

Along with HFCS, trans fats are just about the worst substances that you can be ingesting. They are simply devastatingly bad for your health.

A mountain of research has shown that in addition to all of their other health destroying effects, trans fats also inhibit glucose dispersal and promote insulin resistance. They also have been shown to support preferential fat storage around the belly.

Check your labels and if you see trans fats or hydrogenated oils on them, find something else to eat.

Where do you sit on the low carb continuum?

Look if you are 20 or more pounds (10 kilos) above your fighting weight then the low carb (remember low processed High GI carbs!) is the best way to lose fat. Just be aware that apart from very fibrous carbs (like broccoli or spinach) you’re likely already very insulin resistant so just about any carbs you eat will end up being stored as fat unless you are doing regular challenging workouts and following the diet advice from previous blog posts.

The Research shows that the best approach for folk in this grouping to improve their insulin sensitivity is for them to lose body fat through low-carb / higher protein eating.

The good news is that the leaner you get the more diet options you have available to you.

A natural Glucose Dispersal Agent

If your  insulin resistance level is high, then your carb intake should be low. If your insulin sensitivity is high, then your carb  intake can be higher. Logically if your resistance / sensitivity is in the midle then modest carbs is the way to go.

Since insulin resistance is closely correlated with body fat so the fatter you are the fewer carbs you have. So if your body fat is above 20% for a male & 25% for a female – no carbs for you!! Well low GI carbs anyway in modest quantities.

If you run between 12 to 20 (or 25)% then you can up your carbs, especially if you are regularly working out.

Les than 10% – eat clean, but pretty much whatever you want.

So insulin has benefits as well as drawbacks and once again the negatives are tied to excessive processed carbs and trnsfats…

Be well, see you again soon.

A Beginners Workout to Help You Sculpt an Incredible Body with Bodyweight Training

Posted on by

Welcome Back!

Here is a simple and intense 2 -part workout, each of which you can perform 3 times a week in the comfort of your own home, at the park or beach using just your bodyweight.

It combines strength with intense cardio and uses the interval / HIIT protocol. This means that it has a high metabolic cost, will burn fat during the workout and more importantly for hours afterwards.

Background Information:

  • A circuit is when you move from one exercise to the next without resting in between.
  • Then rest for no more than 2 minutes before doing the next circuit.
  • All rest should be ‘active’ rest where you do not stand still but just keep moving by walking around. Not only will you get your breath back more quickly, but you will add the overall metabolic cost.
  • Reps are a guide only – if you can do more reps then do so, if less then that’s okay – match your efforts to your capability.
  • If push ups are too difficult substitute them with push ups from your knees.
  • Chin / Pull ups:  if you can’t do the reps then use one leg on a secure (ie won’t slip or tip) chair to assist in pushing you to the top of the movement.
    • Once there ‘lock’ your arms & back and fight your weight all the way down. This called an eccentric contraction and will give you sore muscles but will also help you develop strength more quickly.
    • Concentrate on bringing your elbows to your ribs rather than your chin over the bar. This activates your back .

      Like a squat for your upper body...

  • Rope Jumping (skipping) count every second step. If 100 is too many aim for 50 & then work up from there.
  • Add 1 more round each week until you are doing 8 rounds, and then try another workout.
  • Try to add at least 1 rep each workout to your push ups, lunges & squats. Aim for 10 reps with the Chin / pull ups. (When you get here you will be stronger than just about everyone else you’ll come across in your life!)

Work out #1:

Three (3) rounds of:

  • Rope Jumping, 100 Count
  • Push Ups, 10 reps
  • Forward Lunges, 10 reps each leg
  • Rope Jumping 100 Count
  • Chin / Pull ups, 5-10 reps
  • Squats, 20 reps
  • Rope Jumping, 100 count

Complete 1 circuit and rest for 2 minutes and then go again until you finish all 3 rounds. Do this 3 days a week.

Work Out #2

Do this work out the days in between the body weight workout above – 3 days a week.

Go to the park (or if you are feeling particularly adventurous) the beach and do some sprints.

Why sprint? Well ever seen a fat sprinter?

Not everyone wants to look like this - but the point is, sprinters are not fat!

Sprinting fits into the HIIT protocol, is challenging, has a high metabolic cost and will help you burn fat. It also gives your workouts balance. It should take no more than 20 minutes.

  • Gently jog around the park / along the beach to make sure that your hips, knees & ankles are loose and your leg muscles are warmed up.
  • Step out 50 metres
  • Run the 50 metres as fast as you can
  • Don’t stop moving at the 50 metre mark but drop to walking / jogging speed and take a 2 minute period whilst still moving.
    • This ‘active rest’ is important as it helps move lactic acid out of the working muscles and stops them from tightening up.
    • Keeping moving also adds to the overall metabolic cost and post workout ‘Afterburn’.
  • Repeat until you have done 3 rounds.
  • Work up to 10 rounds by adding 1 round every second work out.

Do some hamstring & quad stretching afterwards when the muscles are loose & pliable and stretching will do the most good.

Upping the Ante:

Body Weight Work out:

Once you are able to hit or exceed the rep targets in the body weight work out you can add intensity a number of ways.

  • You can do more reps
  • You can do more rounds
  • You can add exercises into each round (add a set of burpees /  squat thrusts after the push ups and after the Chin ups for example)
  • You can vary your exercises (try spiderman push ups instead of regular ones, or jumping lunges instead of split ones for example.)
  • You can add weight via a vest.

    Great way to up the ante for working out at home!

NB weighted vests are NOT recommended for chin ups – This is for 2 reasons – firstly using your own bodyweight on this exercise is challenging enough by itself and it will take some time for you to work up to doing 10 reps a time. Secondly, and depending upon the type of home chinning bar you are using, you will find that most home chinning bars are not strong enough to handle added weight  – I weigh 100KG and if I added even the lightest vest I own I will be close to its top rating of 110 kg.

However if you are using a chinning bar that is part of another, stronger set up feel free to add weight once you can do 10 reps. Adding weight before then will be counterproductive.

Sprint Intervals:

  • Take note of your time and try to get faster over the same distance.
  • Increase the number of rounds.
  • Increase the distance from 50 to 75 metres and then from 75 to 100.
  • Try doing your sprints uphill
  • If at the beach try doing using the dunes (super tough!!)
  • Set a timed protocol where you sprint for 20 seconds, jog / walk for 40 and then repeat for a period of 5 minutes initially working up from there.

  • Go long or go hard...

    Use Tabata intervals – 8 rounds of sprinting for 10 seconds followed by 20 seconds of active rest.

  • You can add weight via vest – again be careful – the vest must not only fit snug enough so that the weights don’t beat you half to death by moving around whilst you are running but also allow your chest to move freely so you can breathe. NOT recommended except for those looking to become superhuman.

Well there you have it a simple, do-it-in-the-comfort-of-your-own-home work out that fits into my philosophy of reconditioning & improving the efficiency of your metabolism through interval / HIIT training.

You will burn fat and become leaner just with the body weight training – adding in the sprinting will increase your fat burn and metabolic efficiency but is not an absolute necessity.

However your results will be greater if you do both.

Strength Training & Metabolic Boosting

Posted on by

Welcome back!!

A few posts ago I wrote about Interval training, particularly HIIT – high intensity interval training and why it is the best exercise protocol to use to lose fat – and it is.

Great for HIIT or 'normal' strength training...

Especially when you combine it with some form of resistance (ie strength) training. Thing is combining HIIT with strength training is VERY intense and can lead to burn out very quickly if you are properly familiar with how to use them correctly.

So what do you do if you can’y do HIIT everyday?

As you know if you have been a regular reader – you can’t out run or out lift a bad diet. But you can recondition your metabolism through a variety of means.

My choice is to keep eating the right way (low processed carbs, high protein, high fruit & vegetable intake) and to use strength training when I want either a break from HIIT or just as an alternative.

Resistance / Strength training, involves using weights, bands, kettlebells, body weight, weighted vests or other forms of resistance to force your body to move differently and work harder than it does in everyday life.

By working differently from our everyday activity and challenging our bodies at the same time we can increase our metabolic rate.

Going for a run, performing a HIIT session or doing a strength training workout and the way they affect your metabolic rate is quite different.Previously we have seen that HIIT (Interval) training has the greatest efffect on overal metabolism.

Remember it is how long for and by how much any activity boosts your metabolism that really has an impact on your ability to lose body fat when your diet is under control.

Let’s talk about the components of our metabolism:

First we have our resting metabolic rate, or RMR. This is the energy needed (counted in calories or kilojoules) to keep our bodies alive – our heart beating, our lungs breathing, etc.This is the ‘lying on the couch & not doing anything’ measurement.

Our RMR makes up about 60 to 80 percent of our total metabolic rate, so the more we can boost this the more fat we will be burning. To raise our RMR we need to recondition and boost our overall metabolism. Increasing physical activity, especially by using HIIT & strength training can directly change RMR.

Next there is the Thermic Effect of Activity, or TEA. Basically this is a measurement of how many calories are burnt by our bodies through movement. This includes walking, mowing the lawn, bringing in the groceries and so on. So your TEA is higher on the days you play touch football than the ones where you watch DVDs all day because it covers all of the activities that we engage in every day to live our lives. .

The more active you are, the more your total metabolic rate increases.

The easy way to view Metabolism

Third, we have the Thermic Effect of Food, or TEF. This is the amount of energy that your body expends to consume and digest food and then put the nuturients in the food to use to create more energy, repair the body etc. As you know you can increase your metabolism simply my eating more protein, more fibrous fruit & vegetables and less processed carbs & fat. Why? Because protein & fibrous fruit & vegetables can use up to 22% more energy to process than processed crap. As for fat – our bodies are the utimate fat storage devices so fat processing (&storage) requires virtually no energy at all.

So we can view our metabolism as the total number of calories (or kilojoules) our bodies use each day for each metabolic component.

This total energy expenditure  can be derived by using this simple formula: (TEE) = RMR + TEA + TEF.

Because we are all different the enrgy used by each metabolic component is different for each person, resulting in unique metabolic rates.

But why Strength Training?

Strength training increases our TEE by elevating the amount of calories expended in activity (TEA). The harder you strength train, the greater the amount of calories you burn through exercise. This in turn leads to the creation of more lean tissue (which is more metabolically active) which burns more calories at rest.

So strength training not only raises your TEA but also your RMR. Next to HIIT it is the best way to do this.

In turn, if you keep eating clean and also watch that your calorie / kilojoule intake does not exceed your TEE then you will lose body fat.

If you conduct your training session with intensity then they all – strength training , HIIT or running – will increase your energy expenditure both at the time of activity, and for a few hours afterwards. This elevation of your RMR that follows on in the hours after exercise is often called the ‘Afterburn’ and for fat loss it is essential. It can also only be gained by either using a HIIT protocol or through strength training.

By using multiple sets of a challenging weight, scientists have shown that the energy expended afterwards, known as EPOC (excess post-exercise oxygen consumption) can be elevated for 24-36 hours.

Isn't this what we want to achieve?

Strength training can boost your metabolism, but it has to be more challenging than activities you do every day. two or three pound dumbells won’t make much of a difference if the groceries you carry or the child you hug weigh more than this. The key to an elevated metabolism is to challenge your existing strength boundaries.

Otherwise your body won’t  get the challenge it needs to build muscle, lose fat and look better in your clothes – or out of them….and that’s what we’re all looking for, isn’t it?

Interval Training – the #1, not so secret fat loss tool…

Posted on by

Welcome back!

Today I want to look at interval training and what is one better!!

Interval training has been around for a long, long time. Supposedly even the Gladiators used a type of interval training in their preparations for the arena.

You can do intervals by running...

What is interval training? – the classic interval is that used by runners – sprint 100 metres and then walk the remaining 300 metres back to the start. Repeat. And again and again. Really interval is a mix of high intensity, short bursts of effort followed by a lower intensity, longer period of effort and then repeated as often as required or possible for the work out session.

Intervals are back in fashion and are really a research-proven tool to have in your body shape shifting arsenal. They are so good that I recommend that they be a key part of your overall fat loss & general health program.

Regular readers know by now that in order to lose fat there has to be a caloric deficit, a low level of insulin, and there has to be high levels of certain chemicals in the body so that the fat is released from the cells so it can be transported to the working muscles and burned as fuel.

Research has conclusively proven that this all important chemical release is easily achieved through the use of high intensity exercise protocols like Intervals.

But – hang on aren’t intervals just aerobics or cardio dressed up a bit differently? In a word – No! Traditional cardio or aerobics (think treadmills, aerobics classes, recumbent bikes etc etc), require low to moderate intensity over a long period of time. The effect on metabolism tends to be limited to exercise period and does not really recondition it.

Chronic cardio just is not as efficient as Intervals...

It’s true that traditional Cardio / Aerobic work actually burns more fat as a percentage of calories during the activity period than interval training does. But don’t get too excited however – it still burns fewer overall calories.

Interval and NOT aerobic training is by far the best form of exercise for this purpose.

Compared to aerobic training, Interval training:
• Releases more fat burning chemicals
• Burns more calories minute for minute than aerobic exercise and
• Elevates your metabolism during and AFTER the exercise session
The thing is not only are Intervals very demanding, but when used in the classic style they get boring and really hard to stick with. How do we deal with this by moving into what is called metabolic conditioning.

The other exercise protocol that elevates your metabolism and burns fat is resistance training – weight lifting, body weight exercise etc – so why not combine the two?

This is where the fat burning can really take off – doing resistance exercises as a circuit in an interval fashion!

For example you could use pure bodyweight exercises like this:
• Squats x 30
• Push ups x 15
• Pull ups x 5

Do each exercise one after the other without rest. This is one circuit. After each circuit rest for 2 minutes. Repeat 5 times.

You get the idea – you can do this in the gym with barbell or machine exercises, or anywhere using a variety of body weight exercise.

The thing is the fat burn during & after the exercise session is massive. The reconditioning effect on your metabolism is strong and it is hard to get bored…

If you do not have variety in your workout program you are more likely to end up at a fat loss plateau soon rather than later. Variety, changing the positive stress that exercise provides, is one of the keys to keeping that fat loss coming.

Body weight exercises are great for metabolic conditioning...

Smart body shape shifters use 2 different metabolic conditioning workouts each week (done on alternate days 4 – 6 times a week) and change these every 4 – 6 weeks.This keeps the challenge fresh and stops your body becoming too efficient at doing the workout. Remeber homeostasis – your body gets stressed, becomes efficient at the exercise stressor and then starts to use less energy to perform the exercise. This means less fat burning. By changing things around you can stop your body reaching this peak efficiency whilst still burning fat and getting fitter.

Other ways that you modify your metabolic training:
• Switch exercise methods – go from bodyweight exercises to machine, to dumb bells, kettle bells or bands.
• Up the intensity by adding a weighted vest or hand weights
• Increase or decrease the length of the circuit by adding or subtracting exercises respectively
• Increase or decrease the number of circuits per workout
• Increase or decrease the rest time between circuits

In your quest for variety don’t ignore the classic interval exercises like sprinting (great on the beach, up stairs or hills), bike riding, skipping rope or swimming. The trick is to go flat out and then use active rest (keep moving – walk after a sprint, breaststroke after free style for example) to recover before going flat out again.

I like doing kettle bells on one day and mixing a Body weight circuit with some running at the local park on the next. So I use metabolic conditioning and classic intervals…

Whilst there is a clear advantage to using metabolic conditioning workouts over both classic intervals and cardio / aerobics, you can still get a great work out by utilising the interval training circuits on machines.

For example Spin classes often use an interval training approach, you can alternate high intensity with low intensity of stationary bikes, elliptical trainers of even treadmills.

Okay, so how long should you do metabolic condition circuits or intervals for?

There is NO “best” metabolic conditioning or interval training program – no best number of “sets and reps” for fat loss. It depends upon what you like doing, what gives you the best results. The only thing I’d say is that whatever you choose to do has to be challenging and make you work!

I am about efficient time use – the higher the intensity the greater the effect during & after the exercise session. You can, as they say, go hard or go long – you can’t do both. This is why I am against what they now call ‘chronic cardio’ – Why spend an hour on a treadmill when you can better results in 20 minutes with a metabolic conditioning circuit or running intervals in the local park?

However the lack of a ‘Best’ set is a good thing as it allows us to use the all important variety in our approach.

One of these helps...

The time you perform each circuit for has a wide range. There is a thing called the Tabata protocol named after the Japanese researcher who discovered it. Using it you do 20 seconds of an exercise, completing as many reps as possible, rest for 10 seconds, and repeat 8 or 16 times for a total workout time of 4 or 8 minutes. Doesn’t sound like much but if you are doing kettle bell swings, or prisoner squats, or burpees – it really gets your metabolism running!!

At the other end of the scale is the 3, 4 or 5 minute interval circuits where you go hard for several minutes and then rest for the same period of time. Soccer players use these a lot and they are generally referred to as ‘Aerobic intervals’. They are also not, in my opinion, the most efficient for fat loss, but they are good for football players to develop ‘burst endurance’.

Short time circuits enable you to work at near maximum intensity and back up to repeat this effort again & again. This type of training is very taxing! It makes enormous demands of your body and really shakes up your metabolism. They have a downside if you are using most machines though – it is very difficult to do sub 45 second circuits on machines because of their “build up” and “bring down” times.

This is particularly true of treadmills and a number of bikes. Apart from treadmills, you can overcome this by using the machine on the ‘Manual’ setting instead of a programmed one.
If you decide to use short, high-intensity circuits, you need to understand that they require a high level of fitness and that you will have to work up to them. Short rest intervals (like the Tabata protocol) tend to lead to a dramatic drop-off in performance with each successive circuit.

Using a longer (relatively speaking) rest period will allow you to work harder in each successive circuit. This means that your performance in each circuit will be more consistent with less drop off in performance circuit to circuit.

Even these can used in an interval fashion...

Don’t think that intervals or metabolic conditioning workouts are too intense for you – they really are all relative to the individual. You don’t have to go 100% flat out in each type of circuit instead, just work at a bit harder than normal pace. Aim to be tired and a little out of breath at the end of each circuit. Don’t be gasping for breath – if you are you’ve worked too intensely and as we are using these for fat loss this means that you are pushing your fitness level to far too fast. Start conservatively and you will get the hang of it.

Here are some of the more popular timing variations:

8 seconds on, 12 seconds off
This duration was the one used by Australian researchers in the now famous “intervals vs. cardio” study from 2007. The results found that interval circuits helped subjects lose belly fat, but chronic cardio didn’t. It can be extremely difficult to control 8 seconds on, 12 seconds off unless you have a timer like a Gym Boss timer – look them up online, at about $20 they are great!

15 seconds
This is a killer = 15 seconds at max effort followed by a rest period. The truly fit can go 15 on , 15 off – but mere mortals are more likely to need at least 60 seconds recovery time as a minimum after each max effort.

20 seconds on, 10 seconds off
The previously mentioned Tabata method. Short, intense and challenging.

30 seconds on / 90 seconds off / 60 seconds off / 45 seconds off / 30 seconds off
Body weight metabolic conditioning or machine based workouts tend to use a lot of 30 second intervals. Beginners will rest up to 90 seconds between intervals, and as you get fitter you drop your rest period down the more advanced you become.

45 seconds on / 90 seconds off / 60 seconds off / 45 seconds off / 30 seconds off
These intervals are proven for fat loss, will these tax your muscles, and challenge your will to complete each circuit at high intensity.

60 second on / 60 seconds off / 90 seconds off
Similar to the 45 second intervals in terms of benefits and toughness. Use 60-120 seconds of recovery between each.

So there you have it – the best way to drop body fat through exercise.
