When the Body Holds On to Weight No Matter What
The experience is frustratingly familiar to many women with polycystic ovary syndrome. Friends follow the same diet and lose weight; they follow it more strictly and barely shift a kilo. The hunger around certain times of day is intense, cravings for carbohydrates can feel overwhelming, and the weight settles stubbornly around the middle. After years of this, the natural conclusion is that something is wrong with them.
What they are usually not told is that something is, in fact, wrong — but not with their discipline. The weight gain associated with PCOS is not driven by laziness or overeating. It is driven by a metabolic pattern called insulin resistance, which affects up to three-quarters of women with PCOS, and which changes how the body processes the very food it is given. Understanding this connection transforms the question from “why can’t I lose weight?” into “what is my body doing with the energy I give it?”
What Insulin Resistance Actually Means in PCOS
Insulin is one of the body’s most important metabolic messengers. After a meal, the pancreas releases insulin to move glucose from the bloodstream into cells for energy. In insulin resistance, the cells respond sluggishly to this signal. The pancreas compensates by producing more insulin, creating chronically elevated levels of the hormone in the bloodstream — a state known as hyperinsulinaemia.
The relationship between PCOS and insulin resistance runs in both directions. High insulin levels stimulate the ovaries to produce more testosterone and related androgens, which drives many of the hallmark symptoms of PCOS, including irregular periods, acne, and excess hair growth. At the same time, elevated insulin promotes fat storage — particularly abdominal fat — and suppresses the breakdown of stored fat for energy. Weight gain and insulin resistance therefore reinforce each other: insulin resistance makes weight loss harder, and more fat — especially visceral fat — worsens insulin resistance.
This explains why women with PCOS often find that hunger and cravings are not simply a matter of willpower. When insulin is chronically high, blood glucose can dip sharply between meals, triggering intense hunger and a preference for quick-release carbohydrates. The body is not being weak; it is responding to a hormonal environment that actively promotes fat storage and carbohydrate cravings.
Why Generic Diet Plans Do Not Work
Most standard weight loss advice assumes a simple calorie equation: eat less, move more, and the weight will come off. For a woman with PCOS and insulin resistance, this equation leaves out the variable that matters most — the hormonal environment in which those calories are processed. A diet that works for someone with normal insulin sensitivity may produce entirely different results in a body primed to store fat and resist its breakdown.
This is why women with PCOS so often report doing everything right and still failing. Restrictive diets can actually worsen the problem by driving hunger hormones higher while the underlying insulin resistance remains untouched. The approach that works for most people — moderate calorie reduction with standard macronutrient balance — is frequently the approach that works least well for PCOS, not because of any personal failing, but because the metabolic starting point is different.
A Medical Approach to PCOS and Insulin Resistance
At NuYu Medical, the approach to PCOS weight management begins with measurement. A comprehensive assessment includes blood testing that examines fasting glucose, fasting insulin, and markers of insulin resistance, alongside thyroid function, androgen levels, and lipid profiles. This testing does more than confirm a diagnosis — it quantifies how severe the metabolic dysfunction is and provides a baseline against which progress can be measured.
From this data, the clinical team builds a treatment plan that targets the specific drivers identified. For many women, this includes nutritional strategies designed to stabilise blood glucose — prioritising protein, fibre, and lower glycaemic carbohydrates while moderating portion sizes — rather than any extreme elimination diet. For some, GLP-1 medications may be clinically appropriate, as they directly improve insulin sensitivity and appetite regulation. Exercise prescriptions prioritise the forms of movement with the strongest evidence for improving insulin sensitivity, particularly resistance training. Every element of the plan is chosen because it addresses the metabolic reality of PCOS, not because it is a fashionable diet.
Practical Strategies for Managing PCOS Weight
The single most impactful change for most women with PCOS is stabilising blood glucose across the day. Structuring meals so that protein and fibre come first — vegetables, lean protein, legumes — and pairing carbohydrates with protein or healthy fats slows the release of glucose into the bloodstream, reducing the insulin spikes that drive fat storage and cravings. This is not a carbohydrate-free approach; it is a smarter way of eating the carbohydrates a body needs.
Movement that builds muscle earns its place in a PCOS plan. Because muscle tissue is highly insulin-sensitive, strength training two to three times weekly has a direct and measurable effect on how the body handles glucose. Combined with adequate protein intake, resistance training supports the metabolic improvements that help weight loss become possible. Regular review with a doctor or dietitian ensures the plan is adjusted based on blood work and progress, not guesswork.
