Why can't I lose weight even though I'm trying?

You have changed what you eat, you are walking most days, and the scale has not moved in months. That is a common and genuinely frustrating position — and it usually has a physiological explanation rather than a motivational one.

What this could be

There is a particular kind of tiredness that comes from doing the work and not seeing the result. You have cut the rice, you are walking forty minutes, you have been at it for four months, and the number has moved by nothing worth mentioning. People arrive at a clinic in that position expecting to be told they are not trying hard enough. They usually are trying, and the explanation usually lies elsewhere.

Insulin resistance is the commonest single reason effort under-delivers. When cells respond poorly to insulin, the body compensates by producing more of it — and circulating insulin favours fat storage and makes stored fat harder to release. South Asians develop this at lower body weights and younger ages than most reference populations, which is why someone with a BMI of 24 can be metabolically in the same position as a European at 29. Rising fasting glucose, raised triglycerides, a fatty liver on ultrasound and darkened skin folds at the neck or armpits often accompany it.

PCOS, in women, changes the arithmetic. Polycystic ovary syndrome sits on a base of insulin resistance and makes weight reduction slower and more effortful than the same plan produces in someone without it. If periods are irregular, if hair is thinning at the scalp while increasing on the face, and if weight has been stubborn since the late teens, that combination is worth investigating rather than pushing through.

Thyroid function. Hypothyroidism is common in India, more so in women, and it lowers resting energy expenditure while adding fatigue and fluid retention. It rarely explains a large gain by itself, but it makes everything else harder and is one of the simplest things to check.

Muscle, not willpower. Repeated cycles of steep restriction tend to cost muscle. Since muscle is where most glucose is disposed of and much of daily energy is spent, each round can leave the next attempt harder. This is a mechanical problem with a mechanical answer: adequate protein and resistance training, rather than a further reduction in food.

Sleep and stress, which are rarely asked about. Short or fragmented sleep raises appetite and reduces glucose tolerance measurably within days. Obstructive sleep apnoea — loud snoring, witnessed pauses, daytime sleepiness — is under-diagnosed in India and forms a loop with weight in both directions. Sustained stress raises cortisol, which favours abdominal storage specifically.

Medicines that count. Steroids, some antidepressants and antipsychotics, certain diabetes medicines, and some hormonal treatments all shift weight upward. Any of them may be exactly the right medicine for you — the point is that it belongs in the explanation, and it is a conversation for your prescribing doctor.

Two practical notes. Everyday Indian eating is more carbohydrate-dominant and lower in protein than most people estimate, so plans often reduce quantity without changing composition. And a plateau after several months of steady loss is a physiological adaptation, not a verdict.

Conditions commonly associated with this

These are conditions this symptom is commonly associated with. This is a list of things to consider and rule out — not a diagnosis, and not a ranking of what is most likely for you.

When to see a doctor

Most difficulty losing weight is metabolic and slow rather than urgent. A small set of features points to something that needs assessment on its own terms.

Arrange prompt review if weight has risen by more than four or five kilograms within a few weeks alongside swelling of the face, ankles or abdomen — that pattern suggests fluid rather than fat, and fluid points to the heart, kidneys, liver or thyroid. Breathlessness at rest, or waking at night gasping, needs same-day attention.

Purple stretch marks, skin that bruises easily, and weakness climbing stairs or rising from a chair together raise the possibility of excess cortisol and deserve a specific look. Periods that have stopped or become very infrequent, or excessive thirst with frequent urination at night, are each worth mentioning early rather than at the end of an appointment.

Beyond those, it is reasonable to seek assessment when six months of consistent effort has produced no change in weight or waist, when there is a family history of type 2 diabetes, or when you would rather know your actual numbers than keep guessing at them.

This is general education and cannot account for your history, your examination or your reports. If you need advice specific to your health, we’re always happy to see you in consultation.

What to do next

Start by measuring the right things. Weight alone is a noisy signal; add waist circumference at the navel, taken monthly, and a photograph. Waist frequently improves while weight sits still, which is a real result that a scale alone would have hidden from you.

Get a baseline set of blood tests rather than continuing without one. HbA1c, a fasting lipid profile, thyroid function, a liver panel and — where the picture fits — a fasting insulin will tell you whether you have been working against a metabolic headwind. Ordering these through a consultation rather than an off-the-shelf package means the results are interpreted against your history.

Then change composition before you change quantity again. Protein at every meal — dal, curd, paneer, eggs, chicken, fish — is the single most useful shift in most Indian plates, and it protects muscle while the rest changes. Add two sessions a week of resistance work; it improves insulin sensitivity even when weight stays flat.

Protect sleep as a metabolic intervention rather than a luxury. And if you have been on a low-energy plan for months, understand that further reduction is usually the least effective remaining lever. A structured review with someone who can see your numbers alongside your history is a better use of the next three months.

Not everything fits neatly into one box.

If you have several symptoms, or none of this quite matches, a consultation can help connect the pieces rather than guess at them.
