Women with PCOS are often told, in effect, to try harder. Eat less, move more, and the weight will come off as it does for everyone else. When it does not, the conclusion drawn is usually about willpower.
That conclusion is wrong, and it is worth understanding why.
The insulin connection
A majority of women with PCOS have some degree of insulin resistance — their cells respond poorly to insulin, so the body produces more of it to compensate. Elevated insulin does two unhelpful things at once: it encourages fat storage, particularly around the abdomen, and it stimulates the ovaries to produce more androgens.
Those raised androgens drive the symptoms most associated with PCOS — irregular cycles, acne, unwanted hair growth. So weight and hormones are not two separate problems. They feed each other.
This is also why generic calorie-cutting underperforms. A low-calorie diet built on high-GI carbohydrates keeps insulin elevated, and elevated insulin keeps working against you regardless of the calorie total.
What tends to work instead
- Low-GI carbohydrates — millets, whole dals, vegetables — rather than polished rice and refined flour
- Protein at every meal, which steadies both blood sugar and appetite
- Fibre in quantity, which slows glucose absorption and supports oestrogen clearance
- Healthy fats from nuts, seeds and ghee in reasonable amounts
- Regular meals rather than long fasts followed by large meals
The pattern here is consistent: keep insulin steady. That single principle explains most PCOS nutrition advice worth following.
Strength training earns its place
Cardio is useful, but resistance training is particularly valuable with insulin resistance. Muscle is the body’s largest site of glucose disposal — more muscle means more capacity to clear glucose without a large insulin response.
Two or three sessions a week is enough to matter. This does not require a gym; bodyweight work at home counts.
Realistic expectations
Weight loss with PCOS is usually slower than for someone without it. That is a physiological reality, not a personal failing, and expecting otherwise is a reliable route to giving up.
The encouraging part: research suggests losing even 5 to 10 percent of body weight can meaningfully improve insulin sensitivity and, for many women, restore more regular cycles. For someone at 80 kilograms, that is four to eight kilograms — a far smaller target than most people assume they need to hit before anything improves.
