What insulin resistance actually is
Insulin is a hormone your pancreas releases after you eat. Its job is to move glucose out of your bloodstream and into your cells, where it is used for energy or stored.
In insulin resistance, your cells stop responding properly to that signal. The glucose stays in your bloodstream longer than it should. Your pancreas notices, and it responds the only way it can: by producing more insulin.
Your blood sugar may look normal on a standard test, while your insulin levels are considerably elevated.
This is why a routine blood sugar test can come back fine even when insulin resistance is well established. It is also why so many women with PCOS are told their tests are normal when the relevant measurement was never taken.
Why high insulin makes weight loss harder
This is the part that is rarely explained properly, and it is the part that matters most.
Insulin is a storage hormone. When insulin is present, your body is in storage mode: it moves fat into fat cells and, critically, it suppresses the release of stored fat for use as energy.
That second function is the obstacle. Fat loss requires your body to release stored fat and burn it. Elevated insulin actively inhibits that process.
So when you reduce what you eat, your body does not respond the way it would in someone without insulin resistance. It resists releasing its stores. You feel the deficit: hunger, fatigue, low mood, without seeing the result you would expect from it.
You are not eating more than you think. You are working against a hormone whose specific function is to prevent what you are trying to do.
The loop that makes PCOS self-reinforcing
Insulin resistance and PCOS drive each other, which is why the condition is so difficult to break out of without understanding the mechanism.
High insulin raises androgens
Elevated insulin stimulates the ovaries to produce more testosterone and other androgens. This is the direct cause of several PCOS symptoms — unwanted facial hair, hormonal acne, scalp hair thinning.
High androgens disrupt ovulation
Excess androgens interfere with the process by which a follicle matures and releases an egg. Ovulation becomes irregular or stops. This is why periods become unpredictable or disappear.
Weight gain worsens insulin resistance
Fat tissue, particularly around the abdomen, is not inert. It is hormonally active and contributes to further insulin resistance. This raises insulin further. And the loop continues.
This is the reason the condition was renamed PMOS in 2026 . The old name pointed at the ovaries. The new name, polyendocrine metabolic ovarian syndrome, reflects that the condition is driven by interacting hormone systems and metabolism, with the ovaries as one part of a larger picture.
Why the weight sits on your stomach
Women with insulin-resistant PCOS commonly carry weight around the abdomen rather than the hips and thighs, in a pattern more typically associated with male fat distribution.
The reason is androgens. Elevated testosterone changes where the body preferentially stores fat, directing it toward the abdomen. This is why the shape of your weight gain may have changed even if your eating did not.
It matters medically as well as cosmetically. Abdominal fat is more metabolically active and contributes more to insulin resistance than fat stored elsewhere, which tightens the loop further.
You can have insulin resistance at a normal weight
This is widely misunderstood and it costs slim women with PCOS years of being dismissed.
Insulin resistance is not caused by being overweight, and it does not require being overweight. A significant proportion of women with PCOS who are within a normal weight range still have insulin resistance and the symptoms that follow from it: irregular cycles, acne, unwanted hair growth.
Weight is not one of the diagnostic criteria.
How to find out if you have insulin resistance
Ask your doctor. The tests are inexpensive and widely available in Pakistan.
Fasting insulin
Not routinely ordered, and it is the most directly relevant measurement. Ask for it specifically.
Fasting blood glucose
Commonly ordered, but it can appear normal while insulin is elevated, so it is not sufficient on its own.
HbA1c
Shows your average blood sugar over roughly three months. Useful for identifying prediabetes and diabetes.
Oral glucose tolerance test
More informative than fasting glucose alone for detecting early insulin resistance.
Lipid profile
Insulin resistance frequently accompanies raised triglycerides and reduced HDL cholesterol.
If your doctor has only checked fasting blood sugar and told you everything is normal, that is not a complete assessment of insulin resistance.
What actually improves insulin resistance
Four things have meaningful evidence behind them. They are worth more of your attention than anything else in this article.
Walking after meals
Muscle contraction moves glucose out of the bloodstream without requiring insulin at all. This is a separate pathway from the insulin one, and it works even when insulin signalling is impaired.
A ten-to-fifteen-minute walk after your largest meal lowers the post-meal glucose spike measurably. It is free, it requires no equipment, and it is the single highest-value habit available to you.
Resistance training
Muscle is the body’s largest site of glucose disposal. More muscle means more capacity to take up glucose. This is relevant even when the scale does not move.
Reducing refined carbohydrate and sugar
Not eliminating carbohydrate, reducing the foods that produce the sharpest glucose and insulin spikes. In a Pakistani diet, the main contributors are white rice, maida-based breads and snacks, sugar in chai, sweets, and fried items.
Fibre helps here, because it slows how quickly glucose enters the bloodstream from the same meal. Whole chia seeds soaked in water or dahi, and the ispaghul in our Weight Loss Phakki, both work on that principle. Neither is a treatment for insulin resistance. Both make a lower-spike way of eating easier to sustain.
Sleep
A short stretch of poor sleep measurably reduces insulin sensitivity in healthy people. Sustained poor sleep works against everything else on this list.
Weight loss itself, where it applies
A modest reduction in weight improves insulin sensitivity and is associated with the return of more regular cycles in many women.
The frustrating part is that insulin resistance is what makes that reduction difficult, which is why the habits above matter. They improve insulin sensitivity directly, without requiring weight loss first.
What this means for you
If you have been trying to lose weight and failing, and you have been told the problem is your discipline, this is the explanation nobody gave you. The obstacle is real, it is measurable with a blood test, and it has a name.
If you are judging entirely by the scale, you may conclude nothing is working at the exact point when things have started to.
If you are working on cycle symptoms and weight at the same time, our PCOS Tea and Weight Loss Phakki bundle covers both sides of the loop described above. It is our most-ordered combination for that reason.
