A working plan for PCOS

Steady.

PCOS doesn't respond to intensity. It responds to the same unremarkable things done for a long time. This is those things, organised so you don't have to hold them all in your head.

Why any of this works

Four levers, pulled at once

PCOS is a loop rather than a single broken part. Insulin raises androgens, androgens disrupt ovulation, poor sleep raises both, and inflammation greases the whole thing. Everything in this plan exists to pull one of these four. When something feels optional, check which lever it belongs to — that usually settles it.

Insulin

The lever with the longest reach. Most people with PCOS have some degree of insulin resistance, including at a completely normal weight. High insulin tells the ovaries to make more testosterone and pushes SHBG down, which frees up even more of it.

You pull it withProtein and fibre before starch, walking after meals, and muscle.

Androgens

Testosterone and DHEA-S sit behind the symptoms that are hardest to live with — the acne along the jaw, the chin and neck hair, the thinning at the crown. They also interfere with follicles maturing, which is why cycles go long or vanish.

You pull it withWhatever lowers insulin, plus zinc, spearmint, and patience. Skin takes about three months to answer.

Cortisol

The most underrated one. Short sleep raises insulin resistance measurably within days, and chronic stress drives adrenal androgens directly. If your DHEA-S runs high while testosterone is only borderline, this is probably your main lever.

You pull it withA consistent bedtime, morning daylight, and not treating every workout as a test.

Inflammation

Low-grade and mostly invisible — it shows up as a mildly raised hs-CRP. It worsens insulin resistance and makes the ovaries less responsive, so it quietly amplifies the other three.

You pull it withOmega-3s, a lot of plants, enough sleep, and enough calories.

The first ninety days

Add things in this order

Doing all of it in week one is the most reliable way to be doing none of it by week five. Each block only asks you to add two or three things, and you keep whatever's already sticking.

Weeks
1–2

Get a baseline and fix breakfast

Nothing else. Two habits and a blood draw.

  • Book the full lab panel. Fasting, before 10am, cycle day 2–5 if you can manage the timing.
  • Eat about 30g of protein within ninety minutes of waking — see the daily section for what 30g looks like.
  • Walk ten minutes after your largest meal.
Weeks
3–6

Build the floor

  • Two strength sessions a week, full body, thirty to forty minutes.
  • Start inositol. Start vitamin D at whatever dose your result calls for.
  • Lights out by 10:30 on five nights out of seven.
  • Fibre up toward 25–30g a day — beans, berries, chia, leaves.
Weeks
7–12

Refine and re-test

  • Add a third strength day if the first two feel routine rather than heroic.
  • Start eating with the cycle phases — the section below.
  • Fill in your first monthly check-in and compare it to how week one felt.
  • Re-draw the fast-moving markers at week 12: fasting insulin, glucose, HbA1c, testosterone, SHBG, vitamin D.
After

Just keep going

Cycles often take four to six months to shift, and skin runs about a quarter behind everything else. If the daily checklist is mostly getting done, the plan is working even on the weeks it doesn't feel like it.

Eating with your cycle

Four phases, four jobs

Tap a wedge. The segments are drawn to real length, which is why luteal takes up nearly half the ring — it's the longest stretch and the one where blood sugar matters most. With PCOS the phases can run long or skip entirely, so treat this as a loose guide and let your tracking app tell you where you actually are. If a cycle is unclear, default to the luteal rules; they're the safest bet for insulin.

Menstrual DAYS 1–5

Tap a phase — or use ← → after selecting one

Menstrual

Days 1–5 · bleeding

Iron and minerals are leaving. The job is replacing them and keeping inflammation down, which is most of what cramps respond to. This is the week for red meat — it's the most efficient iron you'll get.

Lead with

Red meat, especially beef and lamb. Liver if you'll eat it. Dark leafy greens, lentils, beets, blackstrap molasses.

Pair with

Vitamin C at the same meal — peppers, citrus, strawberries, tomato. It can multiply how much plant iron you absorb.

Comfort that helps

Bone broth and soups, ginger, turmeric, cinnamon, dark chocolate for the magnesium, salmon or sardines for omega-3.

Ease off

Tea within an hour of iron-rich meals — including spearmint and herbal — the tannins block absorption. Move it to between meals this week. Very cold raw meals if they make cramping worse.

A day that fits: Beef and vegetable soup with a squeeze of lemon · steak with roasted peppers and sweet potato · ginger tea and two squares of 85% chocolate · warm oats with molasses and berries.

Follicular

Days 6–13 · rebuilding

Estrogen is climbing and energy usually follows. This is the phase where you have the most appetite for fresh, light food and the most capacity for hard training — spend it. It's also the best window to help your body clear estrogen cleanly.

Lead with

Cruciferous vegetables — broccoli, cabbage, cauliflower, brussels sprouts, and broccoli sprouts if you can find them. They support estrogen metabolism.

Add daily

Ground flaxseed, a tablespoon. Fermented foods — kefir, sauerkraut, kimchi, plain yoghurt — for the gut bacteria that process estrogen.

Protein

Lighter cuts here: chicken, eggs, white fish, tofu, lentils. Still 30g at breakfast.

Keep steady

Higher energy makes it easy to skip meals. Don't — long gaps undo the insulin work faster than almost anything.

A day that fits: Eggs with sautéed cabbage and feta · big salad with chickpeas, sprouts and lemon · kefir with flax and berries · roast chicken with charred broccoli.

Ovulatory

Days 14–16 · the peak

Short and busy. Estrogen peaks then drops fast, and this is the phase PCOS most often struggles to complete. Fat and antioxidants support the hormone-making itself, and fibre helps clear the estrogen surge instead of letting it hang around.

Lead with

Colour and antioxidants — berries, pomegranate, tomatoes, leafy greens, bell peppers.

Fats matter here

Olive oil, avocado, walnuts, salmon, whole eggs. Hormones are built from cholesterol; chronically low fat makes this phase harder.

Zinc

Pumpkin seeds, oysters, beef, cashews. Zinc supports both ovulation and the acne side of things.

Fibre

Keep it high — artichokes, raspberries, beans, oats. This is the estrogen exit route.

A day that fits: Salmon with olive oil and greens · avocado and pumpkin seeds on everything · berries with yoghurt · a proper salad with beans, egg and a real dressing.

Luteal

Days 17–28 · the long one

Progesterone rises, your body burns slightly more energy, and cravings become real physiology rather than weakness. Insulin sensitivity dips in this phase, so this is where blood sugar work pays the most. The mistake is cutting carbs here — that reliably produces a 9pm binge and a bad night's sleep.

Eat the carbs

But make them slow and warm: sweet potato, squash, oats, quinoa, potatoes, sourdough. Always alongside protein or fat, never alone.

Magnesium

Pumpkin seeds, dark chocolate, spinach, almonds, black beans. It blunts cramping, sleeplessness and irritability.

B6 and calcium

Salmon, chickpeas, bananas, potatoes, yoghurt, sardines. The most consistent evidence for easing premenstrual mood and bloating.

Ease off

Restricting food to "undo" the bloating — it backfires within a day. Salt and water actually help it more than cutting back does. Sweet drinks land harder in this phase too.

A day that fits: Oats with peanut butter and banana · chicken and roast squash bowl · dark chocolate and pumpkin seeds in the afternoon, deliberately, before the craving arrives · chilli with beans and a baked potato.

Every day

The daily twelve

Eight out of twelve, most days, beats twelve out of twelve for nine days and then nothing. This resets each morning.

0 of 12
Protein — aim for 100–130g a day

Breakfast 30g · lunch 30–40g · dinner 30–40g · snack 15–20g if you need one. Breakfast is the one that changes the most.

  • Roughly 30g looks like:
  • 4oz cooked chicken, beef or turkey
  • 5oz salmon, or one drained tin of tuna
  • 5 large eggs — or 3 eggs plus ½ cup cottage cheese
  • 1 cup Greek yoghurt plus 2 tbsp hemp seeds
  • 1¼ cups cottage cheese
  • 1½ cups cooked lentils
  • A scoop of protein powder plus 1 cup Greek yoghurt
Fibre — aim for 25–35g a day

8–10g at each meal, plus whatever comes with a snack. Almost nobody hits this by accident — it takes one deliberate fibre item per plate.

  • Roughly 8–10g looks like:
  • 1 cup raspberries or blackberries
  • ¾ cup black beans, chickpeas or lentils
  • 2 tbsp chia seeds
  • 1 whole avocado
  • 1 medium artichoke
  • 2 cups broccoli, plus a pear
  • Oats and sweet potato are lower than people assume — about 4g each. Pair them with something on this list.

Move fibre up gradually over two or three weeks and drink more water alongside it — jumping from 12g to 30g overnight is the usual reason people decide fibre "doesn't agree with them."

Every week

The shape of a week

Movement
  • Two to three strength sessions
  • One longer easy walk or hike
  • 7,000–9,000 steps most days
  • One genuine rest day
Kitchen
  • One prep block: cook a protein, a grain, a tray of veg, a soup
  • Boil six eggs
  • Refill the supplement organiser
  • One dinner you didn't cook, without guilt
Sunday reset
  • Ten minutes: look at the week and pick where the strength sessions go
  • Note anything worth telling your doctor
  • Fill the monthly check-in if it's the last Sunday

The shopping brain

What to keep in the house

There's no PCOS food you're banned from. What actually moves the needle is what's easy to reach for at 6pm — so the list is about stocking, not restricting.

Build meals from these
  • Protein: eggs, chicken thighs, ground beef, salmon, sardines, tinned tuna, Greek yoghurt, cottage cheese, lentils, black beans, tofu
  • Fibre: berries, raspberries, artichokes, broccoli, cabbage, spinach, chia, ground flax, oats, chickpeas
  • Fats: olive oil, avocado, walnuts, almonds, pumpkin seeds, tahini
  • Slow carbs: sweet potato, squash, potatoes (cooled and reheated is even better), quinoa, sourdough, oats, fruit
Small things that do real work
  • Vinegar or lemon on food before a starchy meal
  • Cinnamon in oats and yoghurt
  • Spearmint tea, twice a day, for the androgen side
  • Two Brazil nuts for selenium — not more, they're potent
  • 70%+ dark chocolate as your default sweet thing
  • Frozen everything. Frozen berries and veg count fully and never rot.
Ease up on, rather than ban
  • Sweetened drinks and juice — liquid sugar with nothing to slow it
  • Refined carbs eaten alone: toast by itself, a pastry between meals
  • Very long fasts. Popular advice, poor fit for PCOS and cortisol.
  • Gluten and dairy: individual, not universal. If you suspect one, drop it for three weeks and reintroduce properly rather than cutting both forever on principle.
The five-minute meals
  • Cottage cheese, berries, cinnamon, flax
  • Tinned salmon on sourdough with avocado and lemon
  • Two boiled eggs, hummus, cucumber, olives
  • Greek yoghurt, walnuts, dark chocolate shavings
  • Frozen edamame with salt, and whatever protein is in the fridge
  • Rotisserie chicken over bagged salad with a real dressing

Bring this list to your doctor

Supplements, ranked honestly

Ordered by how good the evidence actually is, not by how loudly they're marketed. Start with the top two or three rather than all of them — if you add eight things at once you'll never know which one worked, and you'll quit when the bill arrives.

WhatTypical doseWhat it's forEvidenceWorth knowing
Myo-inositol + D-chiro inositol (40:1)2g myo-inositol, twice dailyInsulin sensitivity, ovulation, androgensStrongThe best-supported supplement in PCOS. Give it three months. Generally considered safe when trying to conceive, but confirm with your doctor.
Vitamin D3Dose to your lab result — often 1,000–4,000 IUInsulin sensitivity, cycle regularity, moodStrongOnly useful if you're low, and most people are. Test rather than guess. Take with a meal containing fat.
Omega-3 (EPA/DHA)1–2g combined EPA+DHAInflammation, triglycerides, androgensModerateFatty fish twice a week does much the same job.
Magnesium glycinate200–400mg at nightSleep, cramps, insulin, premenstrual moodModerateGlycinate for sleep; citrate if constipation is the issue. Oxide is mostly wasted.
N-acetylcysteine (NAC)600mg, two to three times dailyInsulin sensitivity, ovulationModerateCompares reasonably with metformin in several trials, with fewer stomach complaints.
Zinc15–30mg with foodAcne, unwanted hair, hair sheddingModerateDon't run high doses long-term — it depletes copper.
Spearmint teaTwo cups dailyFree testosterone, facial hairEmergingSmall studies, modest effect, essentially no downside. Pleasant way to hit the target.
Berberine500mg, two to three times dailyInsulin resistance, lipidsModerateStop before trying to conceive, and don't use while pregnant or nursing. Interacts with a long list of medications — clear it with a pharmacist first.
Prenatal with methylfolateDailyBaseline nutrient coverStrongWorth starting three months before any attempt at conceiving, not at a positive test.

Supplements are an addition to a plan, never a replacement for one, and they're not a substitute for treatment your doctor recommends. Run this whole list past your clinician or pharmacist before starting — particularly if you're on any medication, or if conceiving is on the horizon.

Movement

Build muscle, walk a lot, don't grind

Muscle is where most of your glucose ends up, which makes strength training closer to a treatment than a workout. Long punishing cardio does the opposite — it raises cortisol, which raises androgens, which is the loop you're trying to open.

Strength · 2–3×

Full body, 30–40 minutes. Squat or leg press, a hinge, a push, a pull, a carry. Add a little weight or one rep whenever last week felt manageable. Heavy and low-rep is fine and often better.

Walking · daily

The post-meal ten minutes first, steps second. A short walk after eating blunts the glucose rise more than the same walk hours later.

Easy cardio · 1–2×

Thirty to forty-five minutes where you could hold a conversation. Hike, bike, swim, stroller walk. This is the low-cortisol kind.

Intervals · at most 1×

Fifteen to twenty minutes, once a week, only if you're sleeping well. More than that stops helping.

Rest · genuinely

One full day. With PCOS, under-recovering shows up as worse skin and a longer cycle, not just as tiredness.

If you're depleted

Walk and lift, skip the intervals. Adding intensity on top of poor sleep makes every marker worse. This is the most common mistake in PCOS training.

Sleep and cortisol

The 10:30 rule

This gets its own section because it's the lever most people skip and the one with the fastest return. A few short nights measurably worsen insulin sensitivity in healthy people — with PCOS you're starting further back.

Evening
  • 9:45 — wind-down starts. Overhead lights off, lamps only.
  • Magnesium glycinate.
  • Phone out of the bedroom, or at minimum face-down and charging across the room.
  • 10:30 — lights out. Five nights out of seven is the target, not seven.
  • Cool and genuinely dark. Blackout or an eye mask.
Morning
  • Same wake time daily, within about half an hour — including weekends. The anchor matters more than the bedtime.
  • Daylight outside within an hour of waking. Through a window doesn't count for much.
  • Eat within ninety minutes of waking, before anything else gets going.
If you wake at 3am
  • It's often a blood sugar dip. Try a small protein-and-fat snack before bed — a spoonful of nut butter, a boiled egg, a little yoghurt.
  • Check whether dinner was mostly carbohydrate.
  • Check the room temperature. Waking hot is as common a cause as blood sugar.
Cortisol during the day
  • Ten quiet minutes, ideally at the same time daily.
  • Eat regularly — skipped meals are a stress signal, and your body reads them that way.
  • Don't stack a hard workout onto four hours of sleep. Walk instead.
  • If DHEA-S runs high on your panel, this is your main lever. Spend your effort here before anywhere else.

Testing

What to draw, and when

The numbers live in the tracker spreadsheet — this is the timing, which changes results more than almost anything else you control. Get it wrong and you'll be reading noise.

Fast for 10–12 hours

Insulin, glucose, HbA1c, lipids, liver. Water only. A single meal can double fasting insulin.

Book 7–9am

Androgens and cortisol both peak in the morning and fall through the day. Write the draw time on the report.

Cycle day 2–5

LH, FSH, estradiol, and the androgen panel. This is the window every reference range assumes.

7 days after ovulation

Progesterone, and only progesterone. Above 3 ng/mL means you almost certainly ovulated — the most useful single result you can get.

Off the pill

Androgens, SHBG and LH/FSH aren't interpretable on combined hormonal contraception. The numbers describe the pill, not you.

Pause biotin

Three days off biotin and hair/skin/nail supplements before any draw. It skews thyroid and hormone assays into believable but wrong territory.

How often

Baseline: the full panel. Month 3: only the fast movers — fasting insulin, glucose, HbA1c, total and free testosterone, SHBG, vitamin D. Month 6–12: the full panel again. Any cycle you want confirmed: a mid-luteal progesterone. Same lab, same time of day, same cycle day, every time — between-lab variation is often bigger than the change you're trying to see.

For the days it's hard

Things worth remembering

Protein first, then fibre, then the starch.Same food, same meal — a smaller glucose rise purely from sequence.
Ten minutes of quiet is treatment, not a treat.Meditation pulls the cortisol lever directly. It belongs in the protocol, next to the supplements.
Muscle is a hormone organ.Lifting isn't about appearance here. It's where glucose goes instead of into the loop.
Bed by 10:30.One of the highest-return things on this whole page, and the one most likely to get skipped.
Don't skip meals to make up for something.Under-eating raises cortisol and moves the insulin spike to later, bigger. Restriction is not the lever.
PCOS answers in months.Skin at about twelve weeks. Cycles at four to six. Energy is usually first. Nothing has failed at week three.
A bad week is data, not a verdict.You don't restart. You just do tomorrow's twelve.
Eight out of twelve, most days.Consistency at 70% beats perfection that lasts nine days. Aim there on purpose.
