Metabolism – What it is & How you can make it work for you Part 9

How to Keep Your Metabolism Fired-Up as You Age (How to slow the slowing…):

Welcome back to the next to last on this series aboiut your metabolism.

Your Resting Metabolic Rate or RMR is where the majority of our calorie / kilojoule use takes place. The higher this is, the less fat we carry. You see, as we’ve discussed before decreases in your RMR are heavily associated with the reduction of lean muscle tissue.

Age-related weight gain is purely a function of the loss of muscle.

Aesthetically pleasing or not - his metabolism will be faster with this amount of muscle...Muscle is a hungry tissue and requires a lot of calories to maintain. The more functional muscle mass you have the faster your metabolism and the lower your fat stores. Muscle tissue atrophies –diminishes – as we age because in general we move less, exercise less and become generally physically less active.

While it’s not entirely clear whether this muscle loss is just a result of the ageing process or because most people become less and less active as they get older, what is clear that you do not have to accept it as inevitable.

It is hard to argue with your mitochondria, but nonetheless you can offset many of the factors which cause the slowing of your metabolism. The quickest way to disrupt your current metabolic set point and loosen your current homeostatic state is through metabolically costly exercise. Challenging regular exercise actually increases the number of mitochondria and as we’ve seen already, the more of these little ‘furnaces’ you have, the more calories you burn. (See the soon to be released Lose 20 in 30 Work Out Manual)

Research has shown that regular, metabolically taxing strength and resistance training can reduce, reverse or even prevent this muscle loss. This in turn leads to less fat. So the first way we can work to negate the

The best insurance against age-related fat gain is lifting weights…

metabolic slowing effects of aging is by maintaining our muscle mass through regular challenging conscious exercise.

Move more and lift weights dammit!

However the type, duration and choice of exercises are vitally important. A specific exercise protocol called Metabolic Conditioning (referred to as Metabolic Chains in the  promised Lose 20 in 30 program) has to be used. The up coming Lose 20 in 30 Exercise Manual has all of the details on this.

But exercise is only one of a number of the lifestyle modifications that you can adopt to keep your metabolic rate fired-up – regardless of your age.

What can I do to increase or maintain my metabolic rate as I age?

You can (Warning – recap of some previous information ahead!!):

  • Ensure that you engage in at least 20 to 25 minutes of medium to high metabolic cost exercise every second day
  • Ensure that you engage in 20 – 35 minutes of moderate physical activity on the alternate days.
  • Begin eating more small meals throughout the days instead of just 1 or 2 larger meals.
  • Look for other small ways to move more and stay more active. Take a parking spot away from the main entrance of the mall. Likewise do the now clichéd but still effective, take the steps instead of the elevator. Give the dog an extra walk each day or just go for a walk each evening after dinner etc etc.
  • Stop drinking soda & fruit juices and drink more cold water and green tea instead.
  • Avoid foods that contain high levels of saturated fats and any level of transfats wherever possible.
  • Sleep – enough & your metabolism thrives, too littel & you get fat – simple really…

    Avoid highly processed foods wherever possible especially the ‘whites’ – sugar, flour, rice and other processed carbs.

  • Don’t eat anything labelled ‘diet’
  • Try to eat more un – or low processed foods like fruit & veges, fish, eggs and protein.
  • Eat more protein & fibre.
  • Add spices to your meals.
  • Take fish oil
  • Take Vitamn D ( the D3 version NOT the D2)
  • Eat like the Lose 20 in 30 Fuel manual suggests – slow, low GI carbs, good fats, lean proteins and as little processed carbs as possible.
  • Try out stress reducing activities like Yoga, Pilates, Tai Chi or start meditating daily. A walk on the beach, in the Park, in a Forest or a Field – are all great stress busters.
  • Take 500mg of Vitamin C when stressed this will reduce cortisol significantly.
  • Make love more often.

Your metabolic rate has always been, and will always be, a result of a combination of your activity levels, caloric intake, and the types of foods that you consume. Low or unprocessed foods are simply better for your metabolism and make it easier for your body to maintain a faster metabolism.

It’s very important for all of us, regardless of our ages, to eat better proper foods, more often and to maintain regular levels of physical activity. To a very large degree your metabolic rate is yours to control.

Remember your age or even your sex does not matter, in order to lose fat fast, efficiently and to transform your metabolism three things have to fall into place – you must have an absolute burning desire to change the way you look & feel, you must have a strategic training protocol to follow which disrupts your current

A strong old age – something to aspire to …and within reach for us all.

homeostatic set point and ramps up & re-conditions your metabolism and lastly you must follow a diet that supports the reconditioning of your metabolism by creating a calorie deficit whilst firing up your metabolism and manipulating your hormones.

In the end, age will slow us down. But by staying active and eating well, the experts agree: You can slow the effects of a slowing metabolism.To a very large extent your metabolic rate is yours to control.

Take Away: You’ve heard it before – you don’t have to accept the metabolic slow down of aging – you can offset it!!

Metabolism – What it is & How you can make it work for you Part 8

Welcome back!

So what causes downwards trends in your Metabolic Rate:

Children’s per body weight kilo metabolic rate is about 200% that of adults. Because they have a much higher proportion of their body composition made up metabolically active tissue (heart, lungs, kidneys, brain etc) in comparison to adults, are undergoing the demands of growth and simply having a more active lifestyle kids have a much higher metabolism than grownups.

It’s not just their activity level that makes children’s metabolism run so much higher than an adults…

However as growth finalises getting and we get older the proportion of metabolic active organs to our body composition drops. This alone means that our RMR decreases. Your RMR drops round about 25% between the ages of 6 and 18 as your adult proportions are reached and growth slows and eventually halts.

After age 18 your RMR decreases at least 2-3% for each decade that follows. (Many researchers put this figure even higher if you live the typical Western lifestyle.) By the time you have hit 40 your RMR is usually more than 40% less than it was as a child.

So this drop in RMR is coupled with an increasing loss of fat-free lean body mass as we take on adult, ‘real life’ responsibilities and  move less, exercise less, eat metabolism slowing foods and eat more than our slowing RMR demands. Usually we eat more ‘on the go’, less regularly and the wrong foods with a lower TEF – so this compounds the RMR dropping effect.

So as we age we experience a lower RMR, lower TEF, and less TEA – these all combine to create a less lean, fatter, less metabolically active environment for our bodies. Even worse because these changes are gradual our bodies accept them and then strive to maintain them via a state of homeostasis.

Face it – by the time we are in our 40’s, if not before, most of us are well on the way to a future of not moving well, having larger fat stores than is good for our health and in fact be starting to experience firsthand some of the myriad health issues that our Western lifestyle is rife with.

So does Metabolism slow down or do we?

The answer is both.

Unfortunately the exception – not the rule!! (but most of us could if we wanted it badly enough…)

As we age we certainly move slower as the ability to contract our muscles lessens and undertake less physical activity.

The slowing of your metabolism is real. Our cells have miniature ‘furnaces’ in them called mitochondria. These mitochondria burn the fuel supplied to them and as we get older they become less & less efficient at burning fuel and recent research suggests that their numbers also decline as we age. This leads to a slower metabolic rate not just at rest but also for all activity.

Next we have a delightful process called sarcopenia, which is a fancy name for muscle wasting. Once past the age of 50 our ability to retain muscle tissue in the face of poor nutrition and lack of exercise diminishes rapidly. Again since muscle burns more energy than fat, this means the metabolism slows down. This means it is harder to burn off a cupcake when you are in your twenties than it is in your sixties!!

Lastly being overweight slows metabolism because overweight people burn fat even less efficiently. Add these together as the years go by, and it is little wonder that we get fatter, less lean and that the inches start to get more & more numerous around your waist.

Take Away: Your Metabolism slows as you age – especially if you follow the typical Western lifestyle & diet.

How to be ‘Fit and Flat’ at every age

Welcome back!!

This week we’re going to look at what you need to do to be fit with a flat belly at the different stages of your life. Because of the drop in metabolic rate, our ability to recover, our abuility to produce hormones and just plain strength we need to adopt  a slightly different approach to bot eating and exercise depending upon our age.

Here are some general rules…

20-something

At this age you can get away with more and, for the most part, your youth will soak it all up.

Flat Belly? Avoid grain based foods

I can remember being able to eat 5 big meals a day and still retaining a flt stomach. But by my late 20’s this was not the case – my abs starterd disappearing..

The lesson here is that being a 20-something doesn’t give you immunity against stomach fat. In fact

the habits that you adopt and create in your 20’s will either make your fitness & leannesss easier or hareder for the upcoming decades.

The biggest things to avoid eating are refined sugars (alcohol, sweets, biscuits, etc) and starchy, grain based carbohydrates (white bread, pasta, rice, etc)..

The way to exercise is to lift strong, run fast and do both often.And if you stay flexible, your abs will remain strong and your stomach flat, so try adding some semi-regular (at least) yoga or pilates. Learn and practise good posture and keep your overall body fat down.

30-something

You need to eat meals that are high in vegetables, lean animal protein and some fruit. If you’re a male avoid vegetable derived proteins – the phytoestrogens in these will begin to lower youtesterone levels even more than natural age progression.

There are only a few you consider using regularly...

If you didn’t take them in your 20s, definitely start taking fish oil supplements, Vitamin D3, a good multi and some E & C. These will go a long way towards to helping you stay lean and healthy.

For exercise keep a good mix happening : Cardio (such as sprinting, rowing, running, swimming, or even the occasional aerobics class), weight training (kettle bells, body weight, weights) and flexibility (such as yoga or pilates). Look at adding some relaxing exercises like Tai Chi or Chi Kung – these are really important in combatting stress levels and as we know increased stress means increased levels of cortisol which means more belly fat!!

 

40-something

Okay – now we begin to hit the downward spiral unless we either: 1) take strong corrective action NOW or 2) continue with good habits developed in our 20’s or 30’s. if you don’t do either then you will begin to lose vitality, fitness and really begin to add fat.

Your lean muscle mass starts to decrease around age 40.  Avoiding grain based starchy carbohydrates (especially those with a high glycemic load) and refined sugar will help to keep your insulin levels down and, in turn, will slow down the amount of lean muscle mass you lose. You will also need up your amount of

Being smart in your 40's means looking this good in your 50's & beyond!!

protein, as it provides the building blocks of lean muscle mass – and these need all the help they can get.

In order to preserve your muscles masss (& you can still add more if needs be!!) lift heavy at least twice a week (complex exercises in the 4-6 rep range – thing deadlifts & squats!), start doing lots & lots of chin ups to preserve, strength and your posture; cut spriniting back to a weekly exercise and get some swimming or cycling (even if its 2 or 3 spin classes) in. Exercise in your 40’s is essential if you are to remainlean & vital into your 70’s & beyond!!

Increasing your fish-oil consumption will lower inflammation and in turn help keep your stomach as flat as possible post-40. Your abs and (especially for the ladies who ‘ve had kids) pelvic-floor muscles need to be focused on now more than ever, so pilates, yoga and lots of planks & core work is essential.

50-something and above

More of the same – move more, lift as heavy as able, do squats & chin ups & push ups, swim or bike, run and stretch, tai Chi or yoga – stay active and challengingly so. Most exercise should be resistance-based, using weights and pulleys, as this increases lean muscle mass, as well as releasing serotonin (the feel-good hormone). It will also leave you with a strong core which will protect your hips, back and knees from injury, as well as keeping your stomach flat.

Turning 50 means that you become more aware than ever of how your body takes longer to recover and how

Tosca Reno - at age 50+

you begin to become at least half a step slower…However it does not mean that you have to relegate yourself to dimming vitality, lowered sexuality and the scrap heap. Even without good habits formed in your 20’s, 30’s and / or 40’s you can still slow down the slide . A lot. But you have to get itno it and realise that once you get lean & fit again it will be even harder to do so if you let yourself slide again…

Your meals should be frequest with protein and lots of veges and fruits as often as possible.Eat as many colours of fruit & vegetables as you can daily – the phytonutrients & co-factors are needed like never before. Dark green leafy vegetables are important for their calcium content and you need to be eating lots of calcium-rich foods to reduce your increased risk of osteoporosis.

So the lessons don’t change – avoid sugars & trans fats, cut back or eliminate grains, avoid starchy carbs, lift heavy weigths, move more and do it regularly throughout life.

One more piece of inspiration – this is a 69 year tested & avowed natural (ie no steroids) Doctor who left it until his 50’s to get into shape. Great genetics for sure – but I’d like to look as close to looking that good as my genetics allow at that age.

See you next week. Be well.
