Muscle Growth, Preservation, Insulin & Leucine

Posted on September 22, 2013 by jghethe

Welcome back!

I believe that as a species we humans were designed to be lean, fit, muscular and healthy. We were not designed to be fat, overweight, beset with diabetes, whole body inflammation, heart disease and the rest of the gamut of modern lifestyle diseases. Our genetic promise is being steadily eroded by lack of exercise and a diet high in ‘fractured’ / denatured / highly processed foods that predisposes us to chronic diseases…

And no I am not about to start ranting about the need to return to eating & living like our pre-agricultural forebears. (Although a lot of the anti-grain information does bear at least some consideration if you want to pursue optimal health…) Even those folk who exercise regularly have trouble reaching and then maintaining a state of lean muscular health.

With all of the information available, with the explosion in personal trainers, DVDs for home and gyms why is this case?

Certainly a major part of the issue is the fact that despite the huge amount of information out there and the writings of people like Craig Ballantyne, Pauls Rigby and John Romanello people still chooses ineffective types of exercise.

I have written at length here about the benefits of high-intensity interval training (HIIT), of mixing low rep high weight training with medium rep medium training – but done circuit style. I have sung the praises of sprinting and Tabata protocols and kettle bells… Once you begin to work out in HIIT fashion using whatever modality you choose you can and do shift your body shape amazingly fast.

I think a major part of the problem from an exercise perspective, is the overuse of ‘Trash’ exercise – and most traditional cardio falls into this category. Too much focus on cardio (especially the ‘normal’ treadmill, exercise bike etc) with little strength or mobility work is, I am convinced the reason why so many folk try so hard yet see so little change in their physique.

Doing long sessions of cardio just does not work except to perhaps help you convince yourself that you are doing all you can and the fat that is not shifting is due to genetics or you being ‘big boned’ or…when simply you are indulging in a form of exercise that was prescribed back in the 1970’s when the scientific study of exercise performance was in its infancy. It still has a lot to learn but this exercise science is now at least a robust adolescent yet we persist in following outmoded and discredited exercise protocols.

I’ve already written extensively about the benefits of HIIT & Metabolic Conditioning exercise protocols, so here I will look at what you need in terms of nutrition to achieve optimal muscle building for leanness, fitness, and health.

Nutrition for Fitness

The commonly held belief is that if you want to build muscle, you need to eat lots & lots of protein and stacks of carbs because after all aren’t carbs our bodies preferred fuel? Yes & No. However, the evidence that has emerged over the past several years shows us it’s not that simple.

In the upcoming ‘Lose 20 in 30’ program I talk about research that shows that your body has a mechanism that allows it to build muscle even when deprived of food. Basically it is tied to a number of survival mechanisms which you can turn on by lifting heavy weights for lots of low rep sets – your body becomes convinced that it is under threat from the weights and so shifts gear to preserve if not actively build muscle even in a state of calorie deficit.

An important part of this mechanism is that some types of amino acids can act as signallers to certain muscle cell genes and turn them ‘on’ to grow muscle tissue. See, it turns out, that amino acids and protein are not just present in our bodies to act as the building blocks for tissues and muscle. Even during times of food deprivation, as long as these amino acids are circulating through your blood stream, you can preserve and even build muscle.

I have said many times before that we eat too little lean protein and too many processed carbs. The ratio between your protein intake and carbs is important for muscle preservation and growth – and it becomes even more important the older we grow. Time & again research from all over the world

has shown that high-carbohydrate diets fail to build muscle. Even in younger people. In study after study it is always the high-protein, low processed-carbohydrate diet that proves the most effective both for muscle building, metabolism boosting and fat loss.

So in order to live up to our ‘genetic promise’ of being lean, fit & muscular; there are two primary nutrition factors we need to pay attention to:

A high-protein, low processed -carbohydrate diet
And a diet high in amino acids – especially one called leucine

One Amino above them all…

Branch Chain Amino Acids (BCAAs) are truly the building blocks of our bodies and, as we have seen, also serve as gene signallers as well as a number of other functions.

Amino Acids are split into essential and non-essential. The difference being that essential amino acids cannot be made in the body (like Vitamin C) and needs to come from our food. Non-essential amino acids CAN be made by the body.

The amino acids regarded as essential for humans are phenylalanine, valine, threonine, tryptophan, isoleucine, methionine, leucine, lysine, and histidine. (Histidine was added in the last decade expanding the traditional 8 essential BCAAs to 9)

Leucine is a very powerful muscle preserver & builder. It serves multiple functions in your body the most important of which (for today’s blog) is that it acts as the signalling mechanism for the mTOR (Mammalian Target of Rapamycin) mechanism. No need to reach for your BioMed dictionary – simply put this mechanism is the one which causes protein to be created and builds your muscle.

However, as is so often the case, in order to get its full benefits, you need to take in far more than the recommended daily allowance (RDA).

Don’t forget the RDA is based on the minimum amount of a vitamin or mineral or other nutrient that a body would need to stay alive. It is not based on the amount needed for optimal health.

It turns out that we need what the RDA advocates would view as massive amounts of this amino acid.

Outside of BCAAs supplements, Whey protein, and quality cheeses (again because of their high whey content) have the highest concentrations of leucine and a number of other BCAAs.

Getting leucine into your diet is easy. However it is also a BCAA that is used very much for energy, recovery and repair which for most of us leaves very little over for use as a muscle building agent. This is why we need large quantities of it to get enough into our bloodstream in excess of the repair & recovery needs so that it can signal the genes to grow more muscle. We need more than maintenance quantities.

Okay I hear you say, we’ll simply take a supplement. Like so many other chemicals which our bodies use there can be side effects. Leucine from food sources has zero potential for causing side effects, but using a leucine only free form amino acid supplement can be counterproductive.

Too much of leucine by itself can cause insulin resistance ( and we know that this means slower metabolisms and increased storage) by impairing your body’s glycemic control.

Now as much as I believe in supplements (especially Fish / Krill Oil and Vitamin D) in general macronutrients act in concert with one another and too much of one affects the interplay of others. Really wherever possible it is best to eat whole foods – we appear to be programmed to benefit most from whole food nutrition.

So how much leucine from food instead of supplements, do you need to consume to get results?

Maintenance doses of leucine range from 1-3 grams per day, in order to move beyond this it has been estimated that leucine requirement should be about 8g – 16g daily. Given that per 100 grams, Whey has 8 grams of leucine, cheddar cheese about 4 grams, egg yolks 1.4 grams, beef about 2grams, chicken 1.4 grams and salmon 1.6 – there seems to be a lot of food needed to be eaten.

So in order to get your 8 gram leucine to preserve & grow muscle you would need to eat the following amounts of food:

a pound and a half of chicken (750grams)
three pounds of pork (1.5 kg)
over a pound of almonds (500 grams & over 3000 calories)
over a pound and a half of raw eggs (16 eggs)
half a pound of raw cheddar cheese (250grams)

And only 3oz (about 100gr) of high-quality whey.

So once again it is a no-brainer – adding a good quality whey protein to your diet will help you preserve & grow muscle even if you are cutting overall calories.

Carb Quality is important as well…

In order to get to our genetic promise we need to be careful about where we get our carbs from. You can get your carbs from cakes, cookies, sodas, foods containing high fructose corn syrup, from breads and pasta, or from vegetables, legumes & fruits. The source of the carbs you eat makes a major difference to your metabolism, leanness & overall health.

It only takes 1 meal of high GI carbs to reduce the sensitivity of your insulin receptors. Follow it up with a second and your body will use this next load of carbs, especially if they are simple carbs even less effectively and so on…

It is no secret that I am pro-carb and anti processed carbs. Processed carbs are denatured / fractured foods and just not good for you on a regular basis. Low-glycemic fibrous carbohydrates are best for your body. Best for insulin sensitivity, best for increasing metabolism (see my previous posts). Nuts and seeds especially walnuts and almonds contain not just carbs but healthy fats, lots of fibre and even some protein.

I personally believe (and there is an increasing amount of research to bear this out) that grains are rarely ideal sources of carbs. I love good bread as much as the next person and I certainly view Oats a great breakfast food but vegetables & fruits are the way to go for the carbs you need.

Fructose containing foods are at the bottom of the list. No, not fibrous fruit like Apples, pears or Kiwi fruits – but processed carbs & foods especially those containing High Fructose Corn syrup. HFCS is widely viewed as the main culprit in the ever increasing waistline of the Western world.

Whilst fructose is low on the glycemic index, it’s vital to realise that it is metabolised differently from other sugars and can directly – and adversely – affect insulin and leptin signalling. Both of which are near the top of the list in terms of controlling fat storage and metabolism. Your liver detects insulin activity, which helps your body determine how to metabolise your food. Insulin spikes caused by sugars in your blood stream are detected by your liver and it takes steps to regulate this. Because fructose rarely ever appears on its own in nature when it hits your liver with only a certain amount it can process and lacking an insulin spike the waste products of this metabolism accumulate in your liver. Too much of this and the liver itself develops insulin resistance.

But it gets worse – these by-products are then released and your body converts them to triglycerides whilst lowering HDL (the good cholesterol). All of this gives you a cocktail of insulin resistance, high blood lipids and likely hypertension and heart disease.

I’d even go so far as to say that if a food contains HFCS it is bad for you.

Want to lose Muscle? Get Insulin Resistant…

Insulin is a prime mover hormone – one of the most important, and amongst the most anabolic.

Insulin helps signals your body to move glucose from outside your cells into them, it affects your hunger levels on its own and through interaction with both ghrelin & leptin.

The insulin cascade is also a vital part of the mTOR signalling (other hormones do as well like testosterone, but the effect is greater with insulin as a part of the process) – if your body is insulin resistant this muscle preserving & building signal just does not get out and your muscles waste.

So use HIIT, eat more protein, include whey and cheese to get your leucine and lastly avoid the processed carbs. This is as close to a magic bullet for fat loss as there is.

Be well.

Two favourite foods that are killing us!!!

Posted on November 21, 2012 by jghethe

Hi welcome back:

Today’s post is about a simple way to help you and your loved ones to improve your health, support weight loss and yes increase leanness.

It does require some exercise – the exercise of willpower…

Just about the worst 2 foods you can eat / ingest / scarf down are…fries and soft drinks (soda to our American friends!)

Yep – just removing these two ‘foods’ from your diet will lead to improved health, less fat storage, less whole body inflammation and more besides.

This is NOT to say that avoiding fries’ ‘ Soft drinks will cure all diseases known to man, nor will it overnight cure diabetes, obesity or heart disease BUT if enough folk did eliminate these 2 foods from their diet the cumulative effect would be an amazing decrease in overall illness from diseases like those mentioned above.

We’d simply be a healthier society with healthier individuals in it.

Why you ask? Well…

Pretty much most ‘foods’ or food-like substances have something in that is semi / sort of ‘good’ for you…

In the case of soft drinks they have water. And water is essential for life and wellbeing. But we can water from a whole lot of other sources without having to take on board all of the other crap that soft drinks / soda contain…

Soda is either loaded with sugar (usually of the high fructose corn syrup variety see this post for the evils associated with that), added sugar (variation of dextrose, maltose, sucrose or HFCS again) certainly have loads of chemicals and colourings and even sodium.

In the US of A up to 25% of daily calories come from sugar with a whopping 7% from soft drinks / sodas. That is a lot of sugar, a lot of insulin spiking, a lot of fat storage and a lot of body inflammation right there…

Okay so you’ll drink the zero sugar ones…not so fast!! The diet ones use artificial sweeteners and whilst the jury is still out on their long term effects on human beings (and some of the more hysterical internet rants & warnings have been disproven) they still carry lots of other chemicals & colourings. And they still not be good for you. An increasing body of research shows that people who drink diet drinks actually stimulate their appetite and can sabotage their diets through this mechanism…

Which brings us to fries. They’re made out of potato and spuds are essentially benign aren’t they? Again – it depends. If you are making your own fries (their thicker cousins – chips) from whole potatoes store or market bought and you are either oven baking or at least frying in lard (yep lard!) then you will end up with a food that has some redeeming features. I mean they would be filling, trans-fat and colouring free. Still not great but acceptable now and again.

The truth is that the store bought fries are loaded with sodium, have colourings added for colour in many cases and are flavoured with more salt and sugar to increase their tastiness. (remember we are genetically wired to love salty and sweet foods and fast food manufacturers in fact processed food manufacturers use this to sell more products.) The potatoes (maybe good quality maybe not) are fried in one of the those pro-inflammatory seed (called vegetable – see marketing) oils which are so high in omega-6 like canola or blended oils – which oil can be used and re-used numerous times before being replaced with ‘fresh’ oil. Two things here – reusing high omega-6 oils for cooking makes them even more prone to become trans-fat laden, more carcinogenic and when I say fresh – I mean not yet cooked in. Most ‘seed’ oils are already rancid when you buy them off the supermarket shelf, never mind about the ones that are supplied by food services.

So trans-fat filled, chemical / sugared / salted yumminess is what a fry basically is. Add to this by glugging down a few teaspoons of sugar, colourings and more chemicals and you have the complete meal if you want to induce inflammation, insulin spikes, fat storage, damage insulin sensitivity, and support the likelihood of diabetes, heart disease and obesity. And that’s before we even think about portion size…

Many folk say that the advice on nutrition is confusing because expert A disagrees with Expert B or opinions change (Remember the crap about no eggs because they’ll raise your cholesterol and give you heart disease which was scientifically proven only it was wrong…).

And you’re right it is confusing and made even more so by the various lobby groups and manufacturers who ‘support’ scientific and University studies into the effects of various ‘simple foods (like sugar) on people.

It’s a play straight out of the Big Tobacco playbook – confuse & muddy the issues and sell lots in the meantime and then say ‘The best available research of the time…’

However when it comes to fries and soft drinks / sodas the only folk you’ll find defending these quasi-foods are the paid spokespeople of the manufacturers or the companies that retail them. Even the oft trotted out ‘as a part of a balance diet’ argument is no longer supported.

Remove these 2 foods from your diet and from that of the people you care about – your body and theirs will thank you by giving you better health and less chance of unnecessary disease.

See you next week.

Be well and think before you put stuff in your mouth…

The Real Truth about Low Carb…

Posted on September 15, 2012 by jghethe

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 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!!

24 Proven Tips for Quick Fat Melting…

Posted on September 9, 2012 by jghethe

Welcome back!!

The last 10 or so weeks have been about using your metabolism in a number of ways to enable your desired fat loss – here are some short tips to support it also…

Remember that a calorie is NOT just a calorie – where a calorie comes from determines how your body will use it and that there is no escaping that a pound / 500 grams of fat is about 3500 calories. To lose a pound / half a kilo of fat you need to create a deficit of 3500calories.

Here are 24 proven tips to adopt that will help you to melt away bodyfat and develop a lean & healthier body…

Change how often you eat – move to eating 4-6 small meals a day instead of the usual 2-3 large meals. As we’ve discussed in earlier posts – by eating more often you regulate blood sugar and boost your metabolism to burn more calories.
Eat with smarts! This means eating as many unprocessed (don’t come in a box or bag) foods as possible. Eat whole foods – foods that are close to the way they come from nature as possible. (If your Grandmother wouldn’t immediately recognise it as food don’t eat it!)
Eat more Protein, and the protein that you eat should come from roasts, steaks & chops, chicken breasts, whole birds, turkeys, buffalo, kangaroo or fish etc NOT from salami, pastrami or other processed proteins. Occasionally cheeses and Greek style yoghurts.
The only real exceptions to the processed food rule are whey protein powders for shakes, cold pressed olive oils dairy products..
Get your carbs from fruit & vegetables – and the higher the fibre content of these the better! Low Glycemic carbs choices are generally best – but use your common sense – Ice Cream is low GI on some measures but it is not a fat loss promoting food. Likewise potatoes are a high glycemic food but only if cooked & eaten OUT of their jacket…Eat nuts. Avoid carbs out of a box! If possible avoid grains and grain based foods except for the occasional meal on a weekend.
Eat as close to 10 servings of fruit and vegetables everyday to ensure that you are getting all of your needed micronutrients. Add these to their fibre content and you appetite control, insulin management and overall body health well underway!
Consume at least 25-35 grams of fibre every day – not too difficult if you are eating a lot of fibrous fruit & vegetables. Fibre not only ‘keeps things in motion’ but it also enables you to eat calorie sparse meals and still feel full. Fibre also helps control insulin release and response. And we know that controlling Insulin means controlling potential fat storage!
At every meal consume some form of lean protein.(Whey protein comes into its own here) It helps satisfy hunger and taps into your metabolism by utilising TEF (Thermic Effect of Food– see earlier blogs on this topic) Not only that, but a regular protein intake ensures that your body has all of the essential amino acids it needs to repair & rebuild your body and maintain muscle mass while you are altering your body composition by losing fat.
Eat Fat. Seems contradictory but your body needs essential fatty acidswhich you can only
really get from eating healthy fats. Many nutritionists will tell you to get your fats in a balanced manner – 1/3 from saturated fats, 1/3 from monounsaturated fats, and 1/3 from polyunsaturated fats. This can be difficult to manage if you are living an adult life with adult responsibilities. Better to look at it this way use Olive & Macadamia oils and coconut milk for salads and cooking, eat walnuts & almonds, take an Omega-3 supplement, use butter, avoid margarine and read labels so you don’t ingest transfats.
Avoid vegetable oils (really grain oils) this means Canola, mixed vegetable oil, corn oil, etc etc. Stick with Olive, Macadamia, Coconut, Palm and, in small amounts, nut oils.
Avoid any food that says ‘Low Fat’ as in 98% of times this means high in sugar…
Avoid Sodas, fruit juices, cordial, or heavily sweetened teas & coffees. Drink Green Tea or Water (aim for 2 litres a day of water on top of your tea / coffee intake) the many health benefits of Green Tea are well documented as are the benefits of drinking lots of water. (Added tip – drink chilled water and your body will burn a couple of extra calories just warming it up – not a huge number but it all helps & accumulates!)
Ensure that you get plenty of Omega-3’s (from coldwater fish, walnuts, almonds or easiest of all via supplements) and lots of Vitamin D3. Not only do these nutrients help with reducing inflammation in the body, they have roles to play in fat loss, tissue repair, brain health, and general cell health.
Don’t use a To Do list – create a Habit List and write down the things that move you towards fat loss that you should do every day. Things like eat 6 times a day, eating 10 serves of Fruit & Vegetables, like getting at least 20 minutes of some form of exercise in each day and so on. Make these behaviours & actions habits and you’ll find it easier to do them and best of all your fat loss will be consistent. It will take about 21 days of consistent effort but once you’ve done each of these things 21 times they will have become a habit. Draw up a list with a checkbox for 21 days & stick it on your fridge where you can see it and tick off each habit successfully done each day.
Be consistent with your foods – in other words plan your meals for each day (or more) in advance and buy the foods you need to make them fresh. Most of us rotate between less than 20 different meals – if you identify 15 fat-loss supporting meals that you like then plan your week around them. Consistency comes from repetition.
Speaking of food consistency – try to make what they now call “Super foods” into your meals on a daily basis. This means Berries (especially blueberries – & the frozen are just as nutritious as the fresh!) Nuts, Salmon, natural Greek style yoghurt (never low fat or fat free yoghurt – sugar laden are theses!) olive oil, fish oil, buffalo or kangaroo meat, spinach, broccoli and (yep I don’t like ’em either)brussel sprouts, apples, pears & melons and beans. At worst make sure you add
one of the powdered ‘super green’ supplements to a shake. (Sorry Acai berries and secret Himalayan bat cheeses don’t make the list – neither does whatever this week’s you beaut MLM company ‘must have’ food…)
Aim to get about 35 – 40% of your calories from protein (lean & unprocessed is best), about 30% from healthy fats and the rest from unprocessed, non-grain carbs.
Use herbs & citrus juices, chillies & garlic, olive oil and nuts to add zest 7 flavour to dishes – avoid store bought mayo and salad dressings and you’ll avoid extra calories (surprisingly a lot from sugar)
Sugar is the enemy. It is a poison in the amounts the average Westerner eats. Some types are worse than others (High Fructose Corn Syrup for example). Avoid as much and as often as possible. Read labels and try to cut it out of your diet.
Have a sweet tooth and fruit just doesn’t cut it? Try the lollies and sweets from the diabetic section of your supermarket usually low calorie and always low sugar these can be used sparingly to help you get over any sugar ‘jones’ you may have.
Avoid ‘white foods’ – bread, rice pasta and products made with them.
Get your exercise in. High Intensity Interval Training is best for rapid fat loss (see earlier posts) but if you are not ready for this level of intensity just yet, then simply aim to do at least 20
minutes of movement everyday at a level that makes it just a little hard to have a conversation whilst doing it. Walk fast (with hand weights!) Use some of Craig Ballantyne’s excellent Turbulence Training programs, get on a rowing machine, swim some laps, do some push ups, some squats, some burpees and pull ups, skip rope, try P-90X, sprint some hills, climb some steps – the important thing is to get moving! Just as you can’t out train a bad diet you get faster and more permanent fat loss by combining diet with exercise. Yes, you can reduce body fat just by changing your eating habits but results are slow to come and it takes much longer to lose fat . (Quick rant DON’T fall into the old chronic cardio routines of hours on bikes / ellipticals or step machines – get your heart rate up, move some weights and get on with your day. Anymore than an hour is counterproductive to your fat loss efforts.)
I personally find this one difficult to do – but for a week to 10 days use a food journal and record everything that you eat or drink. Use Fitday.com to see how many calories you are ingesting.
Doing this brings to light all of the hidden foods we eat and makes you more aware of eating so that mindless eating (think popcorn in front of the TV) becomes less easy to slip into. I also suggest hat if your fat loss has stalled that you do the 7-10 day food journal exercise – usually when fat loss stops it is because your food intake has moved in the wrong direction.
Allow yourself to be human and fall off the fat loss wagon now & again. Try to adhere to the 90% rule – that is: stay with the good, fat loss promoting habits 90% of the timeand you’ll getresults even if you don’t follow them the other 10%. If you start edging towards using a 80 / 20 rule (and as good as Paretto’s principle is) you need to stop, re-evaluate and get back on track.

See you next week.

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

Posted on September 1, 2012 by jghethe

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:

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.
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.
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.
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!
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.
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.
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.
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…

Metabolism – What it is & How you can make it work for you Part 10

Posted on August 25, 2012 by jghethe

Welcome back for the final part of this series on your metabolism …

How do I know if my metabolism has increased?

We all know why we want a reconditioned and faster metabolism – but how do you know if your metabolism is increasing?

But how do you know if your metabolism has been raised?

A raised metabolic rate will cause some physiological changes which indicate that your metabolism has been increased:

Greater energy levels:A reconditioned and faster metabolism means that your body is able to more quickly release calories as fuel. This means that your energy systems are running more efficiently and you just have more ‘Get up & Go’ and are able do more. You’ll even find yourself looking forward to working out as it remains challenging but you have the reserves to do more and get more out of it.
A better metabolism = More Energy!!!
Temperature sensitivity alters: For most of us an increase in metabolism means that we produce more heat from our bodies and as a consequence feel the cold less. If you are one of those folk who rarely feel cold you may find that you are feeling hotter more often. You will also find that you break out into a sweat easier when you exercise as your body more quickly heats up and that you tend to sweat more as your body sheds heat. This is a good thing – it means you are burning calories!!
Hormone Levels alter: You can get tested to find out for sure but the research shows that as your metabolism reconditions & speeds up you will experience a change in your hormone profile. Your energy highs & lows will smooth out meaning Insulin is under more control, you’ll feel les hungry meaning Leptin & Ghrelin are playing their roles better and you’ll be adding lean muscle, recovering faster, getting stronger and experiencing a higher libido – all of which means your testosterone levels have increased and likely your cortisol levels have dropped.
Lower Resting Heart rate: This sounds counter to everything we’ve looked at about RMR – but a low resting heart rate is a sign of fitness, and disease aside the fitter & leaner you are the lower your heart rate. Now ‘low’ is an individual thing. My resting heart rate is 56 – not bad for a 50+ year old with a history of smoking, obesity and little exercise for way too many years!! Generally a resting rate of over 80 is unfit, and lower than 60 is good. However judge it after your 30 days based on where you started – if it was 90 and you’ve done your Lose 20 in 30 Program and it is now 79 that is a significant improvement.

Your heart will have a better recovery rate so you can be fitter...

(NB: anytime the body needs to speed up recovery, your heart rate is usually speeded up for some time. So your resting heart rate can be higher on occasion when you have had a particularly challenging session the day before. This is because your body will be in rebuild / recovery mode and increases in heart rate are a part of this as your body removes wastes created by tissue breakdown and also strives to deliver nutrients & other tissue building compounds.)

Exercises get easier: Another sign of an increased metabolism is how much more you can lift / run / do before feeling fatigued. This is increased fitness and increased levels of fitness mean a reconditioned metabolism.
You eat a huge meal and feel full for less time: Whilst you should NOT be eating to bursting at any meal, occasionally we all do and you will find with your new reconditioned, faster metabolism that your body deals with the excess food more quickly and reduces the tendency to bloat. The reason is the body is digesting the food quickly by activating more digestive enzymes so it can rapidly break down the essential nutrients to speed up muscular recovery. Of course if you are eating as the Lose 20 in 30 Program suggests then this will not be an issue for you.

The more of the above signs you experience, the more likely it is that you have reconditioned and increased your metabolism. Of course the other real sign is that your clothes are fitting better and you are seeing changes to your body shape & appearance in the mirror. The best sign of an increased metabolism is less bodyfat.

The real sign - you need to buy smaller clothes!!

Take Away: Signs of increased Metabolism will vary from person to person, but the changes in your appearance and the way your clothes fit are the most visible ones.

Conclusion:

Well there you have it – a good grounding in what metabolism is what affects it and how you can manipulate it to reach your goal of becoming leaner and healthier.

Metabolism – What it is, How You Can Make It Work For You Part 7

Posted on August 4, 2012 by jghethe

Welcome Back !

As different as we all are there is one area that affects us all the same way – Sleep or rather the lack of it. Two of the things that have the greatest blunting effect on your metabolism are stress & a lack of sleep.

Stress and Lack of Sleep can affect your Metabolism

As mentioned earlier your BMR & RMR both decrease as you get older. This means that it is harder for your body to burn calories and harder for you to lose fat. A daily routine of conscious, challenging exercise not only improves your health and fitness, but it increases your RMR.

Stress has both positive and negative impacts on our metabolism.

In reaction to any stress our body initially increases our metabolism, but when the stress becomes prolonged or chronic then the opposite occurs and our metabolism slows down.

The famous ‘Fight of Flight’ response is our body’s reaction to stress. But this heightened physical state can only be sustained for short periods before the body exhausts its stores of the main hormones it responds with.

During periods of stress, your hypothalamus (sort of the hormone control centre – see the Lose 20 in 30 Hormone Primer) instructs the adrenal glands to release three chemicals – epinephrine (adrenaline), norepinephrine and cortisol – into your bloodstream. Initially these three chemicals act to speed up your heart rate, your respiration, your blood pressure, and your overall metabolism.

Epinephrine breaks down glycogen into glucose in the liver, and both it and norepinephrine

increase the amount of circulating free fatty acids for use as a readily available fuel source. However once these have hormones have done their job and we have not used the fuel available then the cortisol kicks in and acts in its role as the belly fat storing hormone. The more prolonged the stress the higher your cortisol levels & the more belly fat you store.

Cortisol serves many important functions, including the rapid release of glycogen stores for immediate energy. But persistent cortisol release requires that other vital systems effectively shut down – immunity, digestion, healthy endocrine function, and so on. Among other stress-health associations, the link between elevated cortisol and weight gain has already been clearly established.

Chronic stress, largely through your hormone system, can disrupt your digestive system resulting in a lower uptake of nutrients and to the stomach producing higher than normal amounts of digestive acids on a prolonged basis. This can lead to IBS – Irritable Bowel Syndrome which definitely lowers nutrient uptake. Stress can often cause our abdomen to become bloated, creating cramping, constipation or even diarrhoea. Even worse studies suggest that stress may make a person more susceptible to the bacteria that cause peptic ulcers.

All of these conditions lead to a lowering of your RMR.

The good news is that if the stress is removed, the body quickly improves and your RMR is raised.

How to de-stress? – Get your sleep!!

Inadequate sleep interferes with nearly every aspect of your fitness & fat loss program. The negative effects of lack of sleep cannot be overstated.

Tired people burn fewer calories because they lack the energy to exercise or work out intensely. Some studies show that even if sleep deprived folk exercise for the same length of time as rested individuals they burn far fewer calories / kilojoules.

Lack of sleep not only makes you too tired to exercise, but it negatively affects your hormone system by altering the hormone levels in your body. Miss enough sleep and you’re effectively disrupting your biological processes, especially those that control & regulate your metabolism.

Lack of sleep affects the levels of cortisol, leptin and ghrelin, three hormones linked with muscle catabolism, belly fat storage, appetite and eating behaviours. Researchers at Stanford University found that when you are sleep deprived, your body decreases production of leptin, (the ‘I’m full & don’t need to eat any more’ hormone) at the same time it increases levels of ghrelin, the hormone that triggers feelings of hunger, and our old friend cortisol – which exists to store fat around your belly and increase the catabolism (tearing down) of your muscle tissue.

The researchers found that nearly three-quarters of the people they studied slept less than

8 hours per night, and that the increase in obesity was directly proportional to the decrease in sleep. This goes a long way towards explaining why very sleep-deprived people are nearly twice as likely to be obese.

Lack of sleep also causes levels of growth hormone to decline. Growth Hormone naturally blunts & counteracts the effects of cortisol so lowering it raises the effects of cortisol. This reduces your muscle mass, your strength, decreases your recovery ability, increases your fat tissue stores, and weakens your immune system.

Too little sleep also raises your Insulin levels increase. This, as we now know, increased insulin makes fat control difficult due to its effect on storing blood sugar as fat. Sleep deprivation also leads to low energy levels which often bring about the dreaded candy / cookie / chip cravings which turn into binges which in turn lead to more insulin release and fat storage – especially if your glycogen stores in your liver & muscles are full. There is even some research which suggests that lack of sleep reduces your body’s ability to store as much glycogen as when it is fully rested. This means that even more blood sugar has to be cleared from your blood stream and with less glycogen storage available, it gets shunted into fat cells.

About 25% of the adult population are insulin resistant. This means that your pancreas

has to pump out a lot more insulin to achieve that same blood sugar clearing effect. It turns out that excessive insulin reduces the ability of your body to burn fat for energy even after the glucose is cleared. Insulin resistance also typically leads to an increase in under the muscle, “visceral fat” around the organs, particularly in the abdomen, and this increases the risk of heart disease. Insulin resistance is even more common if you have diabetes in your family, or if your diet has been high in sugars and other processed carbs, and saturated fats.

Fortunately, by keeping your carbohydrates low-glycemic, and by exercising you reduce the need for this excessive output of insulin, and you keep your fat-burning in high gear. By itself Exercise improves insulin sensitivity.

Even better news is that is improving your sleep immediately reduces the negative effects on your hormone levels & their effect on your body. If you reduce the amount of stress in your life and get more sleep each night, your normal BMR will return. This is not easy in the modern world, with its fast pace, work commutes, paucity of easily available good foods and the general demands on your time, but it can be done.

As for the number of hours of sleep, there’s no one-size-fits-all number of prescribed hours. The right amount for you is based on your individual sleep requirements, although there’s some evidence indicating that somewhere around seven hours a night is ideal from a general health perspective.

Still, numerous factors can influence the amount of sleep you need, such as pregnancy, illness and stress levels, for example. As a general guideline, if you feel sluggish and foggy-headed upon waking, you’re likely not getting enough sleep, or the quality of your sleep is not very good.

Unfortunately, many people are quick to jump on the pill wagon once they start having

sleep problems. But sleeping pills come with numerous side effects and can cause more harm than good – better by far to try to reduce the stressors in your life. At the very least a solid exercise program not only helps burn fat but has been proven to lower the levels of the ‘stress’ hormones in your body.

Bottom line for a healthy metabolism you need at least 7 hours of sleep a night.

Metabolism – What it is & How you can make it work for you Part 6

Posted on July 28, 2012 by jghethe

HI & Welocme back!!

Today we’ll take a quick look at other factors that affect your RMR.

Your RMR isn’t just affected by your TEA & TEF (Thermic Effect of Activity & Thermic Effect of Food) – there are a large number of factors that often work in combination.

Some of these are:

Body size – Because of their size adult bodies have more metabolic active tissue and a
higher RMR than a child. This does not hold true for obese folk as they have a lower RMR in general than lean folk. So to raise your RMR – get leaner
Age – Our metabolism slows with age, due to loss muscle tissue along with hormonal and neurological changes. Not a lot we can do about getting older but keep an eye out for the ‘Counterclockwise’ program (coming later in 2011) which is a 100 day program aimed at reducing your biological markers of age.
Growth – Babies, infants, children and teenagers all have a much higher energy demand per unit of body weight than adults. This is due to the energy demands of growth, the energy needed to maintain their body temperature when little, and the fact that (apart perhaps from teenagers) they are so physically active.
Gender – In general – men have faster metabolisms than women because they tend to be larger, have more muscle tissue and have proportionately less body fat.
Genetic predisposition – Your metabolic rate can also be partly decided by your genes.
Amount of lean muscle tissue – Muscle burns more calories than fat – even at rest. The higher your proportion of muscle tissue to fat the better for your metabolism.
Amount of body fat – Fat cells are metabolically less active than muscle cells (and most other tissues in your body) and burn far fewer calories. It’s simple: the more fat you have the slower your metabolism.
Hormonal and nervous systems – Your RMR is controlled by the nervous and hormonal systems; and any hormonal imbalances (Insulin resistance, or increased Cortisol due to excessive stress, decreased Leptin or raised Ghrelin for example) influences how quickly or slowly your body burns calories / kilojoules. You can affect your hormones through carb manipulation, other dietary ‘tricks’, sleep and exercise. – See the accompanying Lose 20 in 30 Hormone Primer
Dietary deficiencies – If, for example, your diet is low in iodine this reduces thyroid function, which in turn slows your metabolism. (The Lose 20 in 30 Nutrition program makes it damn near impossible to be deficient!)
Environmental temperature – By cooling or heating our immediate environment we can increase out RMR by causing the body to work harder to maintain our normal body temperature. Being too hot or too cold both burns calories / kilojoules.
Infection or illness – In most cases our RMR increases when we are ill because our body has to work harder to build new tissues and to create an immune response. Not recommended for fat loss.

Crash dieting, starving or fasting – Eating too few calories / kilojoules encourages our body to slow its metabolism to conserve energy; this means that your RMR can drop by up to 15 per cent if the change is sudden. Not recommended.
Loss of lean weight due to sudden calorie restriction. This often happens when people go on a strict restricted calorie diet, forcing the body into what is known as “negative nitrogen balance.” This means that more protein is lost than is replaced through your diet and is a sign of more catabolism than is normal. This nitrogen imbalance causes a gradual loss in lean weight and lowers the RMR. On the upcoming Lose 20 in 30 program we avoid this by using a combination of calorie sparse, but nutrient dense foods – with a heavy emphasis on ingesting sufficient quantities of good protein along with an exercise regime that creates the need for your body to maintain its current muscle level if not increase it. This in turn forces your body to take more & more energy from your fat stores. (see the soon to be released Lose 20 in 30 Workout Program for details)
Drugs – A number of drugs, legal, illegal, prescription and non-prescription can be used to increase your RMR. Caffeine is a good example of a legal drug that affects metabolism. Body builders used to use a ‘stack’ of caffeine, ephedrine and aspirin (in a specific ratio which I am NOT going to divulge) to really burn fat as well as some anti-asthma (no NOT Puffers) medications. These had obvious side-effects but they worked by amping up the RMR – something you can do but through effort not pill popping!!

Take Away: So if we manipulate our TEF & TEA wisely & strategically, we can increase our RMR and BMR which leads to a faster overall metabolism, a shift away from fat storage and a healthier, leaner body.

Metabolism – What it is & How you can make it work for you Part 5

Posted on July 21, 2012 by jghethe

Welcome back – last time we looked at the thermic effect of food – how the foods you eat can increase or slow down your metabolism. This time we’re looking at TEA – the Thermic Effect of Activity.

Factors Affecting TEA

It is easy to have an effect on your TEA – move more, sit less, and exercise 6 days a week using HIIT & metabolic conditioning protocols (like those found in upcoming the Lose 20 in 30 Exercise program).

Weighted vest training is a great example of MetCon training!!

Take the stairs, park further away, spend some of each day at work standing up – just add more activity to your day on top of conscious, challenging exercise.

Long traditional cardio is NOT the best way to increase your TEA – you need to use an interval style approach to max out your TEA. The best way to recondition your metabolism is to use a mix of resistance training, interval training and a training style called Metabolic Conditioning. (MetCon)

Ensuring that you work out using strategies that elicit a high metabolic cost, uses high EPOC inducing exercises will increase your RMR and reset your metabolic set point over a short period of time (you’ll see changes in under 30 days!). Again – the use of high intensity intervals, metabolic conditioning, and resistance training are the best forms of exercise to achieve a faster metabolism and a leaner body. (see my other post on HIIT)

The more active we are, the harder we work our bodies & increase the demands on our muscles, the more energy we need for fuel and more importantly the more energy we need for recovery. Regular, challenging exercise increases lean muscle mass and ‘teaches’ the body to burn kilojoules at a faster rate, even when at rest. In this way we can alter what the body currently has as its homeostatic set point for a new one. Remember your body likes things to stay the same so if you add regular exercise this becomes the ‘norm’ and your body adjusts to cater for and adapt to this.

By improving / increasing your TEF & TEA you can in turn raise your RMR. As we have seen – this is important because your RMR accounts for the majority of your calorie / kilojoule burn & use. The higher it is, the more you burn and the leaner you become…

Exercise is the other metabolic affecting variable that we can manipulate, but it needs to be done strategically using the right exercise protocols & techniques.

Metabolic Energy Pathways

There are three different metabolic pathways that the body can use in order to tap into its energy stores.

Looks complicated but using this to your advantage isn’t!!

Without going in-depth to biochemistry, the three energy pathways are:

ATP/PC – This is your quickest and most powerful energy source. It is instantly available and requires no oxygen. ATP itself is the raw fuel for exercise as it is the chemical that drives muscular action. However our bodies only store enough for between 6 & 10 seconds – after that it has to start manufacturing more ATP.
Anaerobic Glycolysis – This is the next quickest energy source and is the way your body creates ATP without oxygen. It is also the process that creates the ‘burn’ in your muscles. This energy system is good for 2 -3 minutes of activity and enables you to continue a relatively high level of activity but it does create a high level of muscle fatigue. This makes it difficult to continue using this metabolic pathway beyond the initial couple of minutes.
Aerobic– This last system is the slowest to act and is good for fuelling a moderate activity level. However it can sustain this level of activity virtually for as long as there is fuel available to use. The aerobic system is the process your body uses to produce ATP but with oxygen.

Following high intensity activity, the aerobic system is required for recovery and to re-establish balance within the body, removing the metabolic by-products, re-synthesising metabolic compounds such as creatine phosphate and providing energy for the repair of exercise induced tissue damage. (She’s definately got her TEF & TEA working for her!!)

In a simple way, our normal energy system is primarily the aerobic system, with the ATP-PC and Glycolitic systems acting as reserves. They provide extra power when needed, but are a very limited resource in comparison.

When we talk about metabolic conditioning exercise we are talking about a strategic exercise protocol that works all three of these energy pathways. (See the Lose 20 in 30 Exercise manual coming soon!)

That’s it for this week – next time we’ll look at other factors that affect your resting metabolic rate – some will surprise you!!

Be well!!

How you can fix a Broken Metabolism Part 3

Posted on June 30, 2012 by jghethe

How can you fix a Broken Metabolism? Part 3

Welcome back !! Remember if you are more than 20lbs (10 KG) overweight the chances are that your metabolism is slowing down and may even, in terms of fat loss, be broken.

In the last post we looked at the effect diet can have on our hormones and how this in turn affects our metabolism in terms of fat storage or fat loss. We saw how certain eating

patterns and foods can trigger fat storage and the anti-starvation hormones which in turn blunt our metabolism and decrease lean tissue.

Today we look at the Thermic Effect of Food (TEF)

Thermic Effect of Food

Macronutrient ‘Burn rates’
Food timing
Meal Frequency

Just eating burns calories. Every bite, chew& swallow, each step of digestion, transport & storage in the processing of food creates what is called the “Thermic Effect of Food.” (TEF). And certain foods require more energy, more metabolic involvement to be processed.

TEF accounts for as much as 10% of our daily calorie expenditure so if we can optimise it we will recondition our metabolism that much faster and for the long term.

Protein for example has a thermic effect or burn rate as high as 30% while the burn rate for fat is as low as 2 or 3%. In fact dietary fat is so easily processed that it creates little thermic effect on the body at all. The quickest way I know to put on loads of body fat is to eat simple carbs with fat and no protein or fibre…

Carbohydrate has a burn rate that falls between the two and depends upon the type of carbohydrate being eaten. Complex, lower GI carbs require more processing and therefore create a stronger thermic effect than high GI carbs and simple sugars & starches.

If you eat an equal number of calories of protein, of fat and of carbohydrates, the calories in the fat are more likely to end up on your waist as fewer of them are burned off by the thermic effect. If you are eating the right foods you are not only re-conditioning your

metabolism but you are burning more calories.

Even better, studies show that the leaner you get the more your TEF increases, and for people who exercise their TEF is even higher. It is almost unfair – the leaner you are the more calories you burn from just eating, whereas the fatter you are the less calories eating consumes…just another reason why reconditioning your metabolism is so important.

You can take major steps in re-conditioning and re-igniting your metabolism by eating foods that are nutrient dense, fibrous and require more effort from your body to process. Likewise you can bring it to a screaming halt by eating too many of the wrong, easy to process foods.

This leads again to an earlier point – not all calories are equal. A calorie is no more than a convenient measure of energy, but calories from different sources require different amounts of energy for our bodies to process them.

So if you eat protein your metabolic rate will rise approximately 30% which means that for every calorie you eat from a protein source your body will burn 30% of one of its’ own calories. For every 100 calories of protein your body will burn 30 calories just to process it.

This is like getting a 30% off discount in calorie intake without the calorie crash scenario. So 100 calories of protein is really a ‘net’ 70 calories – you get 30 for ‘free’

If you eat 100 calories of Carbs your body will burn 10 – 20 calories (on average) to process them. This means that if you eat 500 calories, 10% of them will be burned off by the thermic effect, leaving only 450.

If you eat 100 calories of fat, then your body will burn only 5 calories of its own for processing.

A gram of fat contains more than twice as many calories as a gram of protein or carbohydrate. So a gram of fat not only gives you more calories, but a smaller percentage of them will be burned off by the thermic effect.

While the vitamins and antioxidants in vegetables & fruit are great for you, the fibre is where the rubber really meets the road as far as your metabolism goes. Your body expends a lot more calories digesting fibre and protein than it does simply digesting carbohydrates.

This does not mean that you should only eat protein in your quest to lose body fat, nor should you be blind to the beneficial effects of some types of fat on your metabolism & overall health. What it does mean is that you need to know how to combine protein, complex carbs and ‘good’ fats so that they work optimally to re-condition your metabolism.

Don’t forget our next post will look at the ways that you can use exercise to recondition

your metabolism.

Exercise

Weight bearing – Being Lean = Higher metabolism
Cardio – work long or work hard can’t do both
Metabolic Circuits – HIIT, drive metabolism up and keep it up for up to 30 hours after
NEPA – non-exercise physical activity move more!!
