Insulin-resistant

This type points hardest at blood sugar. Here is what that driver is actually doing, the three things worth changing first, and the bloodwork that settles it.

This pattern starts with cells responding less to insulin. The pancreas compensates by making more of it, and that extra insulin does two things at once: it pushes the ovaries to produce more testosterone, and it tells the liver to make less of the protein that keeps testosterone bound and inactive. The symptoms follow from there.

Written by Sarah Collins, who is not a doctor or a dietitian, and checked against the 2023 International Evidence-Based Guideline for the Assessment and Management of PCOS. No clinician has reviewed this page. Educational only — it is not medical advice and it was written before you took the quiz.

What this result actually means

The driver: Blood sugar and insulin signalling.

Insulin's job is moving glucose out of the blood and into cells. When cells respond less, the pancreas does not give up — it sends more. Blood glucose can sit in the normal range for years while insulin climbs behind it, which is why a normal fasting glucose on its own tells you very little.

The extra insulin is the part that reaches your hormones. It acts on the ovary to increase testosterone production, and it lowers sex hormone-binding globulin (SHBG), the protein that holds testosterone inactive in the blood. More made, less bound, more free and active — that is what drives the skin changes, the hair changes and the missed ovulations.

It is also why this pattern feels like a discipline problem and is not one. Glucose swings generate real, physiological hunger, and high circulating insulin makes stored fat harder to release. The cravings are downstream of a hormone, not of willpower.

What it looks like day to day

You will not have all of these, and having several does not confirm anything on its own. They are here so you can check the result against your own week rather than against a label.

A carb-led breakfast — toast, cereal, a pastry with the coffee — leaves you hungry well before lunch.
There is a reliable mid-afternoon crash, and the thing that fixes it fastest is sugar.
Weight settles around the middle rather than spreading evenly, and it moves slowly even when the eating has not changed.
Soft, velvety darkening of the skin at the back of the neck, the armpits or the groin (acanthosis nigricans), sometimes with small skin tags.
Shakiness, irritability or a headache when a meal runs late.
You feel noticeably steadier on the days you happened to eat protein at breakfast, and have never been sure why.

Three things worth changing first

In this order. Each one is chosen because it acts on the driver above rather than on PCOS in general, and because you can start it this week without buying anything.

Put the protein and the fibre in front of the starch

Eating the protein, vegetables and fat in a meal before the starch flattens the glucose rise from the same plate of food. Nothing is removed and nothing is banned — the order changes. It is the cheapest intervention on this page and the one you can start at your next meal.

Start with: Tomorrow morning: 25–35 g of protein before anything else. Eggs, Greek yoghurt, last night’s chicken, tofu. If breakfast is currently coffee, that is the single highest-return meal you own.

Walk after the meal that hits you hardest

Contracting muscle pulls glucose out of the blood without needing insulin to do it, so a walk lands directly on the mechanism that is struggling. The timing is the whole point — it works during and just after the meal, not six hours later.

Start with: 10–20 minutes within half an hour of your largest meal. Around the block counts. Doing it after every dinner beats doing it properly twice a week.

Add two short strength sessions a week

Muscle is the largest place your body has to put glucose. Building and using more of it improves the disposal problem rather than avoiding it — and unlike cutting harder, it does not make the following month worse.

Start with: Two sessions of 20–30 minutes, whole body, six to eight exercises, heavy enough that the last two repetitions are genuinely difficult. Bands and body weight count. Add a set or a rep each week.

What not to do first

Do not open with a bigger calorie cut. Aggressive restriction tends to end in the rebound you have already lived through, and it does nothing to the insulin signalling underneath. The levers here are the shape of the meal and what happens in the half hour after it.

The bloodwork to ask for

Take this list to the appointment rather than the page. You are asking for tests, not interpreting them — the numbers only mean something next to your history, your medications and each other, which is the part a clinician does and a quiz cannot.

What to ask for if your answers point at insulin-resistant
Test	Why it is on this list	Worth knowing
Fasting insulin	Measures the compensation rather than the failure. This is the number that moves first and the one most often missing from your notes.	Ask for it alongside fasting glucose, from the same draw.
Fasting glucose	Can read normal for years while insulin climbs. Useful mainly next to the insulin result.	The two together are what HOMA-IR is calculated from.
HbA1c	Average glucose over roughly the previous three months.	A screening number, not a sensitive one. It moves late.
Oral glucose tolerance test	Watches how you handle an actual glucose load, which catches what fasting numbers miss.	Ask whether it is appropriate for you. It takes a morning.
Total testosterone, free testosterone, SHBG	Where the insulin story shows up in the androgens. Low SHBG next to a high-normal testosterone is the pairing to look for.	Free testosterone is usually calculated from the other two, so ask for all three.
Triglycerides and HDL	Track with insulin resistance more closely than total cholesterol does.	Ask for the full lipid breakdown, not just the total.
TSH and prolactin	Nothing to do with insulin. They exclude two other causes of irregular cycles before anything gets pinned on PCOS.	Standard part of the workup — check they were actually run.

Fasting insulin is the one to push for. It is frequently left off a "hormone panel", it is the number this whole pattern turns on, and without it you are being assessed on the measurement that changes last.

Where this overlaps with the other three

Insulin resistance and inflammation feed each other, so recognising yourself in the inflammatory result as well is expected rather than contradictory. Start with the blood sugar levers — they are more measurable and they move faster — then revisit inflammation once you have a baseline to compare against.

If two of the four sounded like you, that is the normal outcome rather than a failed quiz. Work the one whose first actions are cheapest for your life right now, give it eight weeks, and read the others when you have something to compare against.

What this result is not

PCOS is diagnosed against the Rotterdam criteria — irregular or absent ovulation, signs of raised androgens on examination or in bloodwork, and the appearance of the ovaries on ultrasound — with two of the three required and other causes excluded first. A questionnaire cannot assess any of the three.

The four types on this site are working categories for sorting advice by what is driving it. They are not a formal classification, they are not the phenotypes used in the research literature, and no blood test confirms them. They are useful because generic PCOS advice averages four different problems into one answer, and the average fits nobody.

So take the bloodwork list and the timeline. Leave the label here.
