Weight management

Weight is a signal, not a verdict. It reports on what a whole system — food, movement, sleep, stress, hormones, medicines and inheritance — has been doing over years. Reading it as a measure of effort or character is both unkind and inaccurate, and it reliably leads to the wrong plan.

The physics is uncontroversial: fat is stored when more energy arrives than is used. The biology is where the real questions sit, because appetite and storage are regulated rather than chosen. Leptin and ghrelin set hunger and fullness. Insulin decides whether fuel is stored or released. Short or broken sleep raises appetite and insulin resistance measurably within days. Sustained stress alters where fat is deposited. An underactive thyroid slows resting energy use. PCOS changes both insulin handling and appetite. Steroids, insulin and sulfonylureas, some antidepressants and antipsychotics, and certain hormonal treatments all move weight upward as a known effect. None of these is a matter of discipline.

There is also the part that catches almost everyone who has lost weight before. After weight comes down, resting energy expenditure falls slightly more than the smaller body accounts for, and hunger signalling increases. The body defends the weight it has known. Regain, in other words, is a physiological response and not a personal failing — which is why the useful question is not how fast but what will hold.

South Asian bodies add a further layer. At the same BMI, Indians tend to carry more fat around the organs and inside the liver, and less skeletal muscle, than the European populations from which the standard cut-offs were drawn. Because muscle is where most glucose is disposed of, less of it means more metabolic strain for the same weight. This is why Indian thresholds are set lower — overweight from a BMI of 23 kg/m², obesity from 25 kg/m² — and why current Indian practice leans on waist measurement and on what the weight is doing to the body, rather than on BMI alone. A waist above 90 cm in men or 80 cm in women is a more informative finding than most BMI values.

The Indian plate deserves its own paragraph. A typical meal is a generous volume of rice or roti, one katori of dal, one sabzi and perhaps curd. It is warm, affordable, culturally coherent and, in most households, low in protein and high in refined carbohydrate. Regional patterns vary a great deal — a Kerala or Bengali plate is built differently from a Punjabi or Gujarati one — and vegetarian and Jain kitchens work with tighter constraints again. Any approach that does not begin from the food actually cooked at home is a plan for someone else.

ⓘThis information is educational and not a diagnosis.

Weight itself is visible, so the useful thing to recognise is what is happening around it.

Where the weight sits matters more than how much of it there is. Weight carried around the abdomen, with a waist that has grown while the scale moved little, points toward visceral fat and metabolic strain. Weight distributed around the hips and thighs carries a different and generally lower risk. Two people at the same weight can sit in quite different places.

The pattern over time is also information. Weight that has climbed slowly over a decade tells a different story from weight that has appeared over eight months, and weight that has been lost and regained several times tells a third. A stretch of months in which the eating and the walking were genuinely consistent and the scale did not answer is information as well, and it points toward the biology rather than toward the effort. Rapid gain over weeks, particularly with a change in medicines, is worth raising with your doctor rather than absorbing.

Then there is what travels with it. Snoring with unrefreshing sleep and daytime sleepiness suggests obstructive sleep apnoea, which is common, under-diagnosed in India and makes weight harder to shift. Irregular cycles, acne and unwanted hair growth point toward PCOS. A darkened, velvety patch of skin at the back of the neck or in the armpits is a visible sign of high circulating insulin. Reflux, knee and low-back pain, breathlessness climbing two floors, and a rising blood pressure are all part of the same picture. A predictable evening pull toward something sweet belongs in the account too — it usually reflects how the day was built rather than a failure of resolve.

What is worth knowing is that most of the metabolic consequences of weight appear in blood results before they appear in how you feel. A person who feels entirely well can have a rising HbA1c, fat in the liver and triglycerides above range. Feeling fine is genuinely good news, and it is not the same as a clear report.

The signs listed below are different in kind. They are not features of carrying extra weight; they suggest something that needs assessment promptly rather than at the next convenient appointment.

Testing in weight management has three purposes: to establish where you are starting from, to find the conditions that make weight harder to move, and to look for the small number of causes that need treating in their own right.

The measurements come first and cost nothing. Waist circumference taken at the level of the navel, weight recorded as a trend rather than a single reading, and blood pressure. Body-composition scales that estimate fat and muscle are useful for direction but are strongly affected by hydration, so a reading after a workout or a long gap without water will mislead. What matters is measuring the same way each time.

The blood work establishes the metabolic picture. HbA1c, a fasting lipid profile, liver enzymes with an ultrasound, and thyroid function form the usual core. Vitamin D, vitamin B12 and ferritin are added often in Indian practice, because deficiency is widespread and because low ferritin in vegetarian women affects energy and exercise tolerance in ways that get blamed on motivation. Uric acid is worth knowing where there is a family history of gout.

Thyroid function deserves a note of its own, because it is the test most often ordered and most often over-interpreted. Frank hypothyroidism does slow energy use and can account for a few kilograms. Subclinical changes, where TSH is mildly raised and free T4 is normal, usually explain much less than people hope. Knowing the result is genuinely useful; expecting it to explain everything is usually a disappointment.

A small number of situations call for a wider look: rapid weight gain with purple stretch marks, easy bruising and weakness rising from a chair; severe cold intolerance and slowed thought; snoring with witnessed pauses in breathing, which warrants a sleep study. These are uncommon, and they change the plan completely when present.

Repeat testing at three to six months is enough to see real movement. Testing more often measures noise and, in practice, mostly produces anxiety.

What follows is what the evidence supports in general terms. What applies to you — particularly anything involving medicines — belongs in a conversation with your own doctor, who knows your history.

Composition before restriction. For most Indian households the highest-yield change is not removing a staple but rebalancing the plate: more protein and vegetables, a measured portion of rice or roti rather than an open-ended one, and fewer refined carbohydrates arriving as biscuits with chai, packaged juices, sweets and fried snacks. Protein at each of the day's meals, rather than concentrated in one, does more for satiety and for muscle retention than any specific food. A practical household measure many families find useful is tracking cooking oil by the litre per person per month — it makes an invisible quantity visible without turning every meal into arithmetic.

Muscle is the point, not a side effect. Resistance training two or three times a week protects the muscle that is otherwise lost alongside fat, and muscle is where most glucose is cleared. Aerobic activity of around 150 minutes a week, built up gradually from wherever you are, adds cardiovascular and liver benefit. Where safe outdoor walking is difficult — and in many Indian cities it genuinely is — home-based bodyweight and resistance-band work is a reasonable substitute rather than a compromise.

Sleep and stress are not soft factors. Six hours of broken sleep raises appetite, insulin resistance and evening eating in controlled studies. In someone who is doing everything else well and seeing nothing move, sleep is frequently the missing variable. Untreated sleep apnoea is worth pursuing for the same reason.

Medicines and surgery have a defined place. Prescription options exist, including the GLP-1 based medicines now available in India, and metabolic surgery has established criteria that are set lower for Asian-Indian patients than for Western populations because of the earlier metabolic risk. Both are decisions made individually, with a full discussion of benefit, side effects, cost and what happens afterwards. Neither replaces the rest; both work alongside it.

Follow-up is where plans succeed or quietly end. A review at twelve weeks, looking at waist, blood results, strength, sleep and energy — not weight alone — gives a fair reading of whether the approach is working. A plateau is information about what to adjust. So is a difficult month. Small steps, repeated and sustained, outperform severe plans that hold for six weeks.

Most of what makes weight management frustrating is that the visible measure — the number on the scale — is the slowest and noisiest signal in the system. Waist, blood glucose, liver enzymes, triglycerides, strength and sleep all move earlier, and understanding them changes what you pay attention to week by week.

The Learning Session below works through reading your own blood results, so that the reports you already have start to make sense as a picture rather than a list of values.

If you would like your history, your reports and your own household's food looked at together, and a plan built around them, that belongs in a consultation rather than an article.
