I’m over 50 years old. Isn’t it too late for me to start weight training? The ‘Can I…?’ series

Leave a comment

I have several well-meaning relatives, especially female, who, whenever they meet me after a long interval, never miss a chance to comment on whether I’ve gained or lost ‘weight’. After having used the ‘lost’ version too many times consecutively, they finally decided to ask me what they should do to get slimmer.

Many of these relatives are middle-aged, between 40 and 60 years old (DISCLAIMER – I don’t subscribe to this dictionary-definition of middle age, which suggests that one becomes ‘old’ at age 60.) The moment I mention to them that apart from adopting an appropriate diet protocol, they should incorporate resistance training into their exercise regimen, they are visibly flummoxed. Isn’t weight training for young persons and bodybuilders, that too, males? Why don’t you tell us how many kilometres to walk or how often to do Yoga?

It is a far too common misconception that resistance training, particularly the kind done in a gym, is not meant for people above a certain age. I would argue, in fact, that it is the one form of exercise that older persons MUST incorporate into their exercise programme. 

One of the surest signs of body aging is the loss of muscle mass. Due to changes in the nature of physical activity, diet, metabolism and hormonal profile (especially for women), one starts to lose muscularity in the absence of a concerted effort to maintain lean mass.

Engaging in regular strength training can help avoid muscular atrophy, or loss of muscle. This, in turn, helps to:

  • avoid loss of strength, which allows one to do simple day-to-day functions, as well as the difficult or occasional ones, easily and effortlessly
  • protect the joints from injury, especially weight-bearing ones, which are essential for independent hassle-free locomotion
  • enable quick recovery in the case of any injury
  • retain good posture, which is especially useful for keeping the spine healthy
  • maintain a strong core, which helps keep up stamina
  • maintain a toned look, which keeps one looking younger than one’s chronological age

Additionally, strength training encourages and sustains fat loss, which is usually considered impossible in the middle age. Music for your ears?

The only caveat would be to test for any chronic medical conditions such as hypertension, diabetes, post-surgery issues, or orthopaedic issues and get a professional practitioner’s clearance before embarking on a resistance-training programme. Also, as for any other age group, one should begin a strength-training programme under the supervision of a qualified instructor.

Here’s some more motivation to try out a gym for the first time – At your next birthday party, expect people to tell you that you look younger this year than at your previous birthday!

I can’t avoid late dinners. Will eating after 7 pm make me gain weight?

2 Comments

It was one of those days early in my self-guided study of what makes us fat that I ran into a senior colleague after several weeks of being at different offices. I couldn’t help but notice that the large-built middle-aged lady had trimmed some inches off her generous posterior. Knowing she would be pleased with an acknowledging compliment, I proceeded to congratulate her on the loss. Preening, she let me in on the secret. “I’ve stopped eating anything after 5 pm,” she said.

Wait, you mean to say that eating an early dinner (5 pm was like mid-day for my 18-hour consulting work schedules those days) can put away so much fat? And I, on the other hand, had been snacking and even binging late into the evening in the name of much-required sustenance on intense projects! It was a Eureka moment for me.

“I’ve stopped eating anything after 5 pm.”

Have you ever fallen into the temptation of resolving to have an early dinner all in the name of weight loss/ fat loss? Or rued the fact that a late night supper might have ruined your entire day’s hard work in following healthy practices?

I’d like to address this concern, a rather thoughtful one I daresay, in three parts.

First, what leads to weight gain, or more technically, fat storage, is a calorie surplus that is not being set off by additional physical activity or a special condition (for example, pregnancy, lactation, recovery from a surgery, etc.). As long as you stay within your calorie requirement based on your total daily energy expenditure (TDEE), there should be no cause for fat storage no matter what time you have your dinner. Again, it is important, that the quality of calories is controlled. More specifically, that the macros are honoured. Mindless stuffing of junk food just because it is within your calories quota will lead to other health issues if not weight gain.

What leads to fat storage is a calorie surplus.

Second, although is no specific curfew time for dinner that applies equally to everybody, it is advisable to finish dinner at least an hour, ideally two, before bedtime. The reason is that the digestive process could get adversely affected with meals timed too close to bedtime. At the same time, sleep can be disrupted due to heartburn, bloating and indigestion, leaving you under-rested the next day.

Finally, there is in fact a scientifically proven method to trigger fat loss that involves eating only within a certain time period. It is popularly known as intermittent fasting (IF) but also goes by the name of alternative day eating/ fasting (ADE or ADF), one-meal-a-day (OMAD) and time restricted feeding (TRF) depending on the format of fasting one follows.

Intermittent fasting is a great tool for fat loss.

The basic idea behind IF is that you time your meals/ feeds such that there is a large enough gap before the next meal to allow your body to tap into its fat stores. The technique is actually a clever trick relying on millions of years of evolutionary processes that allow humans to store fat for lean times and use it when food is scarce. When the body is in a fasting state for at least 14-16 hours, the metabolic pathways shift from burning glucose for energy, the most commonly used mechanism on a standard/ high-carbohydrate diet, to burning fat for energy. This is, perhaps, what caused the inch-loss in my colleague.

Done carefully and systematically, IF is a great tool for fat loss. A big advantage is also that during the feeding intervals, one can eat almost anything – no licence for junk, still. Of course, it has several other advantages too in terms of convenience and saving of time (less planning, less cooking, less packing, less, cleaning up…). Do bear in mind, that this kind of fasting bears no resemblance to the kind of religious fasts that most people in India undertake, what with an elaborate menu of ‘fasting foods’ at the ready.

So, what time will you have dinner?

Counting calories vs counting macros – which is better for fat loss?

1 Comment

I recently came across an infographic in this blogpost, which outlines the principles behind weight loss, in a bid to oversimplify the process. Basically, it conveys that for weight loss to happen, you basically need to be in a calorie deficit. I agree completely. Cutting calories will lead you to that result – weight loss. But is that the correct goal?

I can think of weightlifters, powerlifters, bodybuilders and participants in physique competitions aiming for weight loss to make the appropriate weight class that they want to compete in. But for the majority of the population, the ultimate goal is to achieve an ideal body composition, which means, the optimal body fat levels and, perhaps, a reasonable amount of muscle. That, in turn, means fat loss, not simply weight loss.

Cutting calories will lead you to that result – weight loss. But is that the correct goal?

Eating less may help you lose weight, but it cannot guarantee fat loss. In fact, eating too few calories could have several adverse results:

  • With a consistent calorie deficit, the rate of weight loss tends to slow down, as the body adjusts to a new normal, thus, lowering BMR, which slows fat loss.
  • Cutting calories too low, below the minimum required for sustenance, can threaten the normal functioning of the body.
  • Severe calorie restriction signals the body that it is in semi-starvation mode, causing it to conserve energy, making any weight loss even more difficult.

 

Does that mean that one must not be counting calories for fat loss? Yes and no.

Yes, because your calorie needs depend on your BMR, total daily calorie/ energy expenditure (aka TDEE or TEE) depending on activity levels, and any special conditions such as competition prep (I’m not including ‘pregnancy’ and ‘lactation’ because that is not the right time to aim for fat loss anyway), etc. For a gain in weight, your calorie consumption has to be above the TDEE level. For a loss, it must be below the TDEE level. For maintenance, it should be at the TDEE level. But all this is only related to the number on the scale, your bodyweight.

Does that mean that one must not be counting calories for fat loss? Yes and no.

No, because the quality of the calorie intake is more important for fat loss to occur. The ratio of protein and fat to carbohydrates is what will determine the rate of fat loss.

For several decades, we have deluded ourselves that a diet high in carbs and low in fats is the best for avoiding obesity, thanks to the extremely biased propaganda that Western medical journalism and food processing industry, especially the American variety, dished out in the 1970s. We have now been forced to embrace what our forefathers knew centuries ago – that saturated foods are some of the best sources of energy (think ghee) and whole foods are far more nourishing than any processed or refined ones (for example, whole vegetables vs juices, meat cooked in its own fat vs lean meat, etc.).

A diet rich in good fats – saturated, mono-unsaturated, poly-unsaturated, in that order, moderate in proteins, and low in carbs, tends to serve best when seeking fat loss. Hence, it is critical to track the ratio of these macronutrients, or macros, rather than simply counting calories, when the goal is to lose fat.

Our ancestors knew that fasting was meant to be just that – fasting.

A common proxy that advocates of a carb-rich diet proffer is the Glycemic Index (GI) of foods when comparing which carbs should be allowed on a diet for fat-loss. The lower the GI of a food, they claim, the more suitable it is for weight-loss or fat loss. They also put forward the Glycemic Load (GL) concept as a basis for choosing the ‘right type of carbs’. However, if you take the example of ice cream as a food, which has a GI of 39, middle of the Low range, and a GL of 3, low of the Low range, these numbers would suggest a green light for ice cream on a weight-loss/ fat-loss diet.

The problem is that the only reason ice cream has a low GI and GL is because of the high fat content, which contributes zero GI and GL. Almost all ‘fasting’ foods in India fall in the category of low GI – low GL foods because of the fat-carbs combination. Yet, they are probably the worst category of foods for fat loss since the carbs trigger an insulin response, which, in turn, triggers storage of any carbs that are unutilized for energy in our fat cells as adipose tissue. The result – more body fat! Our ancestors knew that fasting was meant to be just that – fasting – and not a licence for ingesting foods with a poor macro balance.

When seeking fat loss, what will you choose? Low-calorie foods? Low GI/ GL foods? Low-carb foods? Fasts?!

Which is the best cardio exercise? The one that gets you closer to your goal!

2 Comments

I am a big believer in productivity. In my own (elusive) vision of the ‘perfect’ me, I am this highly efficient, multi-tasking, fast-moving, super-worker who gets things done on time, every time, all the time. During one of those eureka moments, when you suddenly hit upon the most elegant solution to not one or two, but half a dozen problems, I realised that I must run a marathon.

The main challenges to which it was an elegant answer were:

  1. Getting enough exercise on a regular basis
  2. Improving my stamina
  3. Gaining a sense of accomplishment
  4. Doing something to show off about to friends and family
  5. Losing weight (I was not aware of the concept of ‘fat loss’ as distinct from ‘weight loss’ then) – secretly the most important reason for signing up!

During one of those eureka moments, I realised that I must run a marathon.

And, thus, I signed up for one of the earliest Goa River Marathons. The name was somewhat misleading because it was actually a Half Marathon then, but daunting, nevertheless, to the cardio-challenged me. I did my research on viable training programmes, and, as always, trusted my own instincts on creating one to work on. I embarked, in earnest, on the three-month run-up to the marathon, crossing one milestone after another. From being able to trot barely 3K at the start of the programme, I was running over 10K nonstop a couple of months in, that too within a respectable number of minutes.

I ran 17K of the 21K on the final day and walked the rest. Not bad, I thought. When the soreness had worn off after a couple of days, I stepped on the scale. I had lost a grand total of 1100 grams, at the end of three months. Umm… something wrong with the scale?!

LISS can lead to some weight loss and fat loss but not if you’ve overcompensated for the calories you burned running by eating them back.

If that’s ever happened to you, you’d know the disappointment it brings. But if you knew the science behind this inadequate result, you’d realise that you could not have expected anything different.

Long distance running is, in essence, low intensity steady state (LISS) cardio work, where your heart rate remains within the range of 40% to 70% of your maximum heart rate. What it prepares you for is exactly that, long distance running, which builds your stamina or endurance. It CAN lead to some weight loss and fat loss depending on how your diet has changed, but not if you’ve overcompensated for the calories you burned running by eating them back. Walking is the most common example of LISS cardio.

If, however, your goal is to lose fat, then you would be better served by indulging in HIIT.

If your goal is to be a long distance runner, with endless stamina, or if you simply enjoy running, go for it. You will be training completely in the aerobic zone, building your cardio-respiratory endurance as well as muscular endurance in the lower body (the weight-bearing joints and muscles in the hips and legs).

If, however, your goal is to lose fat, then you would be better served by indulging in High Intensity Interval Training, popularly known as HIIT. As the name suggests HIIT workouts have periods of highly intense cardio exercises interspersed by intervals of low intensity exercises or full recovery. This mechanism raises your heart rate, within the range of 75% to 90% of your maximum heart rate, for short bursts of time. It targets body fat stores long after the workout since it has a great after-burn effect. The higher the intensity and shorter the interval, the shorter the workout. There are as many adaptations of HIIT programmes available as there are sports – running, spinning, functional training, circuit training, Crossfit, even swimming. Those with cardiac problems should, perhaps, refrain from HIIT.

Other than intensity, an important principle to bear in mind is whether the chosen cardio activity is high-impact or low-impact.

If your goal is general cardio-respiratory endurance to maintain your level of fitness, then moderate intensity training should be your choice. You would be training at an intensity where your heart rate remains within the range of 60% to 75% of your maximum heart rate. Examples include step-aerobics, Zumba, Power Yoga, dancing, swimming, trekking, etc. Those with cardiac problems should get clearance from their healthcare provider before starting such a programme.

Other than intensity, an important principle to bear in mind is whether the chosen cardio activity is high-impact or low-impact. The ‘impact’ here refers to the stress put on weight-bearing joints, your hips, knees and ankles. Those who have never or rarely been on an exercise programme, those with high levels of obesity, those with orthopaedic problems, and those with back/ spinal injuries should ideally begin with no/ low impact cardio exercises such as swimming, training on an elliptical machine, cycling, rowing, light to moderate Yoga, Pilates, or functional training not involving plyometrics. Most other cardio exercises are high-impact, including walking, all types of jogging or running, climbing stairs, skipping, aerobics, Zumba, dancing, plyometrics, etc.

With so much choice out there, it would be hard not to find a cardio workout that works for you. Go for it!

Bodyweight or BMI – which is the best metric for fitness? Neither!

1 Comment

I recounted in an earlier post my experience of weight loss that was hardly apparent to people around me. Many years before that attempt at weight loss, however, I was, in fact, squarely in the middle of the range for ‘ideal bodyweight’. Or so said the Body Mass Index (BMI) chart that adorned the dull walls of my GP’s clinic. As a young girl just barely out of her teenage, however, I was still disappointed by the number on the scale – I had enough ‘issues’, one might say, regarding my body image. If I had known then that, in relation to my height, my weight was very reasonable, as per BMI norms, I might have had more body confidence. But then, again, I would have been chasing the wrong ideal.

Is BMI a better indicator of health and fitness?

We now know that the absolute number on a weighing scale does not mean much by itself. Is BMI a better indicator of health and fitness? It is more complex than the bodyweight metric, but it is definitely inadequate on many counts, and possibly no better. Bodyweight is a critical factor in BMI calculation. As we know, bodyweight is comprised of lean body mass and body fat. However, BMI calculation does not discern between these components. And that is how the cookie crumbles.

Two men with the same age, height and weight, and resultantly the same BMI, should, in theory, have the same level of fitness and/ or degree of risk of lifestyle disease. But what if one of them has a body fat percentage of 10% while the other has 30%? The former has far greater lean mass, and likely more muscle, than the latter, meaning greater strength and no/ low obesity, indicating a lower risk of lifestyle disease. One look at the BMI numbers for some celebrities is enough to realise how meaningless the index really is when comparing one individual with another.

If one has to throw out bodyweight as well as BMI, then what is one left with to gauge health and fitness levels? The singular metric that indicates if you are in a healthy range or not, is your body fat percentage. The proportion of fat in the body indicates how close you are to the ideal body composition for fitness. Among men, the ideal range for body fat percentage is 4% (elite athletes) to 15%, and among women, 8% (elite athletes) to 20%.

Admittedly, it is a little more complex to gauge body fat percentage than getting on a weighing scale or plugging in height and weight measurements into a formula. Skin fold measurements using calipers, bioelectric impedance analysis (BIA), dual energy X-ray absorptiometry (DEXA scanning), air displacement plethysmography, and hydrostatic weighing are the most well known methods, in increasing order of accuracy, complexity, accessibility and cost.

The singular metric that indicates if you are in a healthy range or not, is your body fat percentage.

Along with cardio-respiratory endurance, muscular endurance, musculoskeletal strength and flexibility, ideal body composition rounds out the five components of fitness.

There, you now know what you have to shoot for! If there are lingering doubts, feel free to ping me in the Comments section.

I do Yoga each day. Why do I need to train with weights?

1 Comment

I became a yogini over two decades ago, quite by accident. A college-mate of mine had enrolled for a class on her parents’ recommendation. She suggested I check it out. It was the first time I had tried any activity like it. I discovered not only that I enjoyed the experience but also that I was rather good at it.

Once a month, the 60-something Yoga teacher would invite other Yoga teachers from his matth, which practised the Iyengar style, to break up the monotony. On one such occasion, the invitee teacher led us through a particularly complex routine of yogasanas. As the complexity grew with each pose, more and more participants started to stall. To my surprise, I was among a handful that could complete all the poses as directed. The teacher beamed at me as I arched my back in a perfect Kapotasana, the pigeon pose, and said encouragingly, “Now, strive to maintain this flexibility throughout your life.” So that is what I did.

I am grateful for the day that my friend convinced me to go to that class with her. Yoga has been a constant companion in my life ever since. (My love for it eventually translated into a certification as a Yoga teacher following the Ashtanga philosophy a few years ago.) My belief in Yoga as a way of life has only solidified further.

Around me, I’ve noticed that the attendees in Yoga classes typically span a gradient from middle-aged women (especially homemakers), senior citizens (primarily interested in Pranayama), or exercise-starved corporate employees in a corporate-sponsored class, on one end of the spectrum, to young adrenaline-seeking enthusiasts of Power Yoga and passionate believers of the Yogic philosophy on the other. However, I see people attending Yoga classes to the exclusion of any other form of exercise. And that’s where the disconnect occurs.

Yoga, undoubtedly, has holistic benefits for not just health but also life in general. I would be amongst the first persons to attest to its importance in health and fitness. Among the benefits from Yoga are improved flexibility, which reduces risk of injury; improved breathing, which enhances cardiovascular health and stamina; improved posture and balance, which improve spine and bone health; and relaxation and stress-relief. A highly advanced practice can even improve muscle tone and strength.

I would venture as far as to say that among all types of exercise, the practice of Yogasanas is perhaps the only form to enable improvement on all five components of fitness. And, yet, it has limitations when it comes to progressive overload, a key requirement for developing musculoskeletal strength, the main antidote to aging, which I discussed in detail in my last post.

‘Progressive overload’ simply means giving your body a greater training stimulus once it gets accustomed to a particular level of training. For example, the veteran jogger who runs the same 5 kilometres every day is not progressing in his cardio training while the newbie who adds five more minutes to his ten-minute jog, or adds half a kilometre to his 2-kilometre run, or takes two minutes less to run the same 2 kilometres, is increasing the load and intensity.

Similarly, while training with weights, one might add a few repetitions to a set, or a whole set to an exercise, or increase the weight for a set, or do the same number of sets in less time than before, as a way to increase the load. The idea is to go beyond your comfort zone and push your body to do a little more once a particular training level is reached. For example, a novice to weight training might be able to do 15 reps of an exercise in her first week before experiencing fatigue. Once she finds that she can go up to 20 reps without fatigue, she could increase the weight or resistance to deliver 12 reps. As her muscles gain strength to perform 15-18 reps of the same exercise at the new weight, she can move to a higher weight again.

While doing yogasanas, there is sufficient progression until you learn the correct posture, balance, form, technique, and how to handle your own bodyweight. You might even gain some load by increasing the duration of your practice or adding variations of an exercise to target the same muscle group multiple times. However, it is impossible to add further resistance to such practice once bodyweight training comes within your comfort zone. For example, a person who can perform an Adhomukh Vrikshasana, a handstand, even when adding pushups to the handstand, will need to resort to external weights eventually to seek hypertrophy and further strengthen her shoulders, arms and forearms.

Weight training provides your body with the training stimulus to first break down muscle tissue and then build it up larger to be stronger than before. If fat loss is your goal, then the greater muscle mass means that you carry more metabolically active tissue, which revs your metabolism and increases your Basal Metabolic Rate (BMR). Also, resistance training has the greatest after-burn effect among all types of exercise.  Hence, you burn more calories even when you are at rest and not only during exercise.

So the next time you face a dilemma as to whether to sign up for resistance training despite the daily Yoga class or not, don’t choose. Go for it!

Will eating less help me lose weight?

I caught on to the calorie counting game long before the advent and proliferation of fancy calorie tracking apps. As far back as 2008, I figured I could use my skills at Microsoft Excel to do more than creating financial models and business plans. I created my own calorie counter, following up with several updated versions (I think I even passed it on to some keen friends and relatives). The idea was to have a neat food log to track the calorie intake on a daily basis and ensure it remained at or near my Basal Metabolic Rate (BMR). I arrived at my ideal calorie requirement based on conventional wisdom of the time, and the vision I had of myself six months down the line.

That’s it, I thought. Calorie counting and control is all I need to do to crack the weight loss game.

As my food log got populated, I could see patterns emerging. I utilised the knowledge to tweak my dietary habits. Barring a few social incidents, I managed to remain fairly consistent in sticking to my ever more aggressive calorie goals. Needless to say, at the end of three months, the number on the scale had moved south significantly, despite little support in the form of exercise. I was feeling rather proud of the achievement not only because of the weight loss but also because of this fantastic tool I’d developed. That’s it, I thought. Calorie counting and control is all I need to do to crack the weight loss game.

Not so fast! Despite the shouts of success from the weighing scale, I wasn’t receiving the expected looks, compliments or appreciation from people around me. Why couldn’t they see what I could?

Have you ever had this experience? Or know someone who did? Why was your/ their ‘loss’ not apparent or as significant as what the scale suggested?

The answer, as I discussed in my last post, lies in the type of weight that was lost – water, muscle or fat. Weight loss is easily apparent to the eye of a beholder when there is fat loss. Hence, what an overweight person with a disproportionate body composition must seek is fat loss, not simply weight loss.

Coming back to the original question, eating less does indeed help you lose weight. But, and this is a BIG ‘but’, it will not necessarily help you lose fat if you are eating the wrong type of calories since all calories are not equal.

Weight loss is easily apparent to the eye of a beholder when there is fat loss.

Another phenomenon that you might notice is that the rate of weight loss tends to slow down despite maintaining a calorie deficit, i.e. eating fewer calories than one spends in a day. This is because the BMR of a lighter person is lower, in absolute terms, than that of a heavier person (not to be confused with slow or fast metabolism).

Also, remaining on a calorie-lowering spree could prove dangerous if you reach calorie intake levels so low that they threaten the normal functioning of the body, usually around 1,000 calories, for the average adult.

A collateral fallout of such low calorie intake levels is that the body senses that it is in a semi-starvation mode and holds on to its stores of energy even more closely, potentially stagnating or even reversing weight loss.

So, take the ‘eat less’ formula of weight loss, or rather, fat loss, with a pinch of salt. There are other ways to create a calorie deficit than simply through eating less.

More myths to be flushed out. Soon.

Weight loss or fat loss – which is better?

4 Comments

It was one of those New Year’s eves when you decide you’ve had enough and need to take charge of your life. This particular one was memorable because I actually managed to stick to my health-related resolutions for over five months in the new year. I’d celebrated my first wedding anniversary and the ‘new bride’ glow had started to wane. The weighing scale seemed to have taken on a life of its own, adding numbers at will. Within just a year, I had gained almost 10 lb, firmly putting me in the ‘overweight’ category. I knew I had to do something. Leveraging my past experience, I turned to what I knew had worked in the past – exercise.

I had gained almost 10 lb, firmly putting me in the ‘overweight’ category. I knew I had to do something.

I had always been involved in sports while at school, thanks to a carefully crafted regimen at my quasi-military style alma mater (something I can’t be thankful for enough). While at college, I’d got introduced to Yoga and fallen in love with it. The one thing I wasn’t too proud of was my endurance level. I decided to kill two birds with one stone – improve my stamina, and lose the excess weight. The first hour of my day was, thus, reserved for jogging (as far as I could go without stopping) followed by a routine of intense Yogasanas.

The first moment of exhilaration came when I crossed the 5-km mark for the first time, about eight weeks into my schedule. I was ecstatic to find that I did have some endurance muscle fibres in me after all. The Yoga practice was supporting the cardio schedule admirably, with outstanding improvement in breathing capacity and flexibility. I did not own a scale then so was not distracted by minor fluctuations. The diet was unchanged but the eating was mindful. In about three months, I’d reversed all the damage of ‘newly-wed’ celebratory feasting and then some.

“Are you not keeping well?”

I was feeling highly accomplished. That’s when the reality check happened. One day, a colleague that I was collaborating with again after several months of being on separate projects, casually asked, “Are you not keeping well?” …er…what?

Have you ever had a friend or relative return from a health retreat, where they promise dramatic weight loss, put you on a detox diet of ‘healthy’ juices, boiled and tasteless vegetables, and lentils cooked the ‘zero-oil’ way? You wondered why he looked so feeble that he might fall if he stood in the way of a mildly strong draft of wind? Or a cousin or aunt who took up marathon training to ‘lose the flab’, but at the end of the annual marathon calendar ended up not only weighing several kilos less but also looking several years older, with sunken eyes, gaunt cheeks, and far more wrinkles than you remembered she possessed?

Without going into a lesson on physics, let us understand what ‘weight’ actually means in the context of health and fitness. Our bodyweight comprises two things: lean body mass and body fat. Lean body mass further comprises internal organs, bones, muscles, skin, and body water. Of these, muscle tissue is the most metabolically active tissue, requiring more energy than the other components for growth, repair and maintenance. In terms of changes in weight, it is the muscle mass that can gain or lose weight in the short term, a few weeks or months. The only other component that can change in weight quickly is the water in the body; just a few days are enough.

The prolonged cardio activity definitely burnt the fat, but only after it ate into precious muscle too, hence, the weathered look.

In the case of the friend who patronised the health resort, what he probably lost was water weight. In all probability, he promptly regained all the lost weight within a few weeks of his return as his body readjusted to the usual levels of water intake and retention. In the case of the marathoning cousin, she lost valuable muscle tissue along with the dispensable body fat. The prolonged cardio activity definitely burnt the fat, but only after it ate into precious muscle too, hence, the weathered look.

Appropriate levels of fat loss, while retaining existing skeletal muscle mass, will automatically give you the lean look.

The ideal body composition focuses on body fat as a percentage of your bodyweight. Hence, one should aim to lose fat rather than simply losing weight. Appropriate levels of fat loss, while retaining existing skeletal muscle mass, will automatically give you the lean look.

Now, here come the twin dilemmas:

  1. If a so-called ‘healthy’ diet only helps to lose water weight then what should I eat to lose fat?
  2. If a challenging physical activity like marathon training costs me precious skeletal muscle mass, then how do I protect it? (Everyone says walking is the best exercise. I thought I’d take it to the next level with running. Should I simply walk then?)

More on cracking the dilemmas soon.

‘Fat people are lazy’, ‘Fat people eat too much’, and other such falsehoods

4 Comments

As a kid, I was always in awe of those thin, lanky girls in my class who never got fat. I was even more surprised that they managed to tuck in way more than I did on most occasions. Yet, I was the one who remained ‘plump’ and ‘healthy’ (the latter is a special euphemism used by Indian parents for overweight kids of all ages). By teenage, I realised that I only had to breathe to put on the pounds while the skinny friends of mine could gorge on all manner of goodies without a gram showing up on the scale.

It was also the teen years that I realised I could turn to sports to help redeem my future of being a ‘fatso’. There were entire school terms I did so with a vengeance. And it did work… until I stopped. Every vacation, a period of seven weeks, I successfully managed to turn back time and undo the hard work of an entire 4-month term. Well-meaning aunts and uncles visiting during those holidays would affectionately remind me that I should be ‘more active’ and laze around less.

Every vacation, a period of seven weeks, I successfully managed to turn back time and undo the hard work of an entire 4-month term. 

As an adult, I continued to keep up an exercise regimen, even if it was patchy, so that laziness would not become a reason for being overweight. I had some good months and some not-so-good months. But I realised over time that, in my case, exercise was not a guarantee against weight gain, that simply eating less or moving more than my slim friends would not make me slimmer.

Do you have friends who seem the same size, even at 35, as they did when they were 22, while you sport sufficient curves and bulges to make you ‘look your age’? Or do you look at some of your schoolmates and marvel at how they filled out as adults while you could still turn out in a school uniform and look the part?

I realised over time that simply eating less or moving more than my slim friends would not make me slimmer. 

What causes some people to gain weight, and, indeed, fat, easily while some others seem to have natural insurance against such bodily changes without any apparent effort? In one word, the answer is ‘metabolism’. Metabolism is the sum of chemical processes involved in the breakdown and build-up of cells in our body. Put simply, it is the process by which energy is utilised and created in the body. Each person has a specific rate of metabolism for carrying out day-to-day activities, called the Basal Metabolic Rate (BMR), which determines how fast or slow one’s body handles the energy it receives, i.e. the food they eat.

Now, some people have a fast metabolism, which means their body burns energy from food at a faster rate than the average population (the thin girls from my childhood come to mind). They are the ectomorphs, usually skinny, with a small frame, thin and long limbs, and lean muscle. Their bodies are resistant to weight gain and, in fact, could lose weight quickly if they do not eat enough. This means they have a hard time putting on fat or muscle.

Some have a slow metabolism, as their body burns food energy at a slower rate than the average population (that’s me…sigh). They are the endomorphs, naturally plump, with a wide frame, round and tapered limbs, and a high fat-muscle ratio. Their bodies attract the pounds easily but lose them very slowly. They do, however, gain muscle quickly too.

Then there are the naturally lucky ones – the mesomorphs – the statistically average body type that people usually strive for. They have an athletic, medium build, and gain muscle easily as well as lose fat easily with moderation in exercise and nutrition. Their metabolism is neither too fast nor too slow for maintaining weight and body fat levels provided they follow a moderate diet.

Unfortunately, it is not possible to change one’s basic somatotype.

Three friends – an ecto, an endo and a meso – may each eat exactly the same food in the same quantity for several days and yet show completely different results on the weighing scale even if they started at the same weight. The reason is the rate of their metabolism. Unfortunately, it is not possible to change one’s basic somatotype.

Does that mean that you are stuck with whatever hand fate dealt you? To remain round and chubby if you are an endomorph, or skinny and fragile if you are an ectomorph (curse those mesomorphs!)?? Fortunately, no. Two factors, among others, play a major role in determining the BMR – age and exercise.

Younger people tend to have a relatively higher BMR than older people. That’s the reason daily servings of breads and pasta, typically high on calories, over an entire summer vacation, do little damage to pre-teens as far as weight gain is concerned. The same diet would start to reveal itself within a couple of weeks, if not days, for a middle-aged adult. BMR tends to drop as you grow older. So a 20-something endomorph could achieve the ‘fit’ look far quicker than a 40-year old mesomorph.

Exercise is the big game changer when it comes to increasing the BMR regardless of somatotype or age. Any form of exercise burns calories and adds to the rate of metabolism. (Of course, there are certain forms of exercise that help achieve a BMR higher than others.) Hence, a 35-year old endomorph who does weight-training regularly could look fitter and leaner than a 25-year old mesomorph who does not.

Does this mean that ectomorphs are doomed since they already have a high BMR and would only get thinner if it increased further? What an ectomorph needs is to add body mass, ideally muscle, to maintain a BMR that contributes to fitness. Thankfully, muscle-building is accessible to people of all ages, since it depends on exercise.

Exercise is the big game changer when it comes to increasing the BMR regardless of somatotype or age.

How do you determine what exercise is best for you? Several myths, misconceptions and even prejudices surround this question. I will discuss the most popular ones soon.

The ‘fat-free’ revolution that made us fat – the biggest con in the food industry

1 Comment

In my last post, I recounted my initiation into calorie research. Like many rational and reasonably intelligent people, I arrived at the same conclusions that others do: fat eats into the calorie quota quickly, and it takes up too much space in the body, and, thus, would make me gain body fat. So, I should eat as little fat as possible, which will result in two benefits – I get to eat more, and I don’t get fat!

I soon became a pro at figuring out which foods contained fat and which didn’t, reading food labels for their fat content, looking for skimmed and low-fat options on supermarket shelves, and even cooking fat-free meals. Despite all this diligence, I could avoid neither the hunger pangs nor the weight gain. The way my requirement for larger clothes was going, I knew the weight gain was from fat, not muscle. It was definitely not dietary fat that was making me gain fat thanks to my thoughtfully crafted low-fat diet. Then what was making me fat?

Ever been through this before or know someone who has?

The answer lies in the inequality of calories. A calorie from fat will always remain a calorie from fat, and be stored as triglycerides, until it is required for providing energy. Calories from carbs and protein, however, are talented – they can change form. Carbs that are unutilised by the body are converted to fat and stored for later use. Any protein that is excess, after completing the job of growth, repair and maintenance, also converts to fat.

OK. That explained the metabolism issue, or the lack thereof. But surely the body should have been able to tolerate some amount of fat, especially if it was not getting any from my diet! ‘Some’, yes, but what about the body fat that was already sitting there and not getting used?

The human body has evolved over a couple of thousand millennia to use its resources in the most efficient way possible. For our ancestors of the Stone Age, starvation was a real situation that presented itself every so often. The store of fat in the body was what kept them going during those periods, which could very well last a couple of days or a few weeks. The reason being that the body has unlimited potential to store fat. Our ancestors, however, were different from us in that their bodies knew how to metabolise fat since they needed to do it frequently. On days that they got enough to eat, their bodies used the quick-energy providing foods, i.e. carbs, for immediate uses, and stored dietary fat as, well, fat. Obesity, hence, was a rare occurrence, if at all, since the body was adapted to burning fat.

With the advent of agriculture, about ten millennia ago, a dramatic shift occurred in the eating habits of human beings, since vegetables, fruits, grains and legumes, largely carbohydrates, became far more easily accessible to wide proportions of the population. With a rise in their consumption, the body started adapting to a sugar-burning mechanism (all carbs essentially being a form of sugar, once the fibre is removed). Now, the human body can store only about 2,000 calories worth of carbs at any given time, basically enough to last a day or at most two, versus an average of 30,000 calories from fat.

The food processing industry amplified this change by an order of magnitude. And guess what types of food were processed the most? Carbs! From raw vegetables and fruits to fibre-less juices and sugar-laden smoothies, from dehusked grains to polished ones, flours and breads, from steamed, whole tubers to dried and fried snacks.

With human bodies having essentially switched over to becoming sugar-burning factories from the highly optimised fat-burning, muscle-sparing ones, requiring feeding at small intervals (mostly carbs again) is it any wonder that rates for obesity, not to mention diabetes, have broken all records in the past hundred years?

What we actually needed to do was not cut out the fat from our food but to reduce the proportion of carbs, especially the processed ones.

So, how does one switch back to the fat-burning metabolism without subjecting oneself to starvation? That story begins with understanding ‘metabolism’. And I’ll get to it soon.
