PCOS Diet: What to Eat for Steadier Energy (No Banned Foods)

Search for “PCOS diet” and you’ll find strict rules: no carbs, no dairy, no gluten, no sugar. The reality is kinder. The 2023 international PCOS guideline found no evidence that any one diet is better than another for PCOS.

What matters is a way of eating that steadies blood sugar and that you can actually keep doing. Here’s how to build one.

Why food matters in PCOS

Many people with PCOS have insulin resistance. When blood sugar rises quickly, the body releases more insulin, and high insulin can push up androgen levels and drive cravings. Meals that release energy steadily help break that loop.

Pair, don’t ban

The simplest rule: don’t eat carbohydrates on their own. Pair them with protein, healthy fat or fibre, which slow how fast sugar reaches the blood.

Instead of	Try
Toast with jam	Toast with eggs or nut butter
Fruit juice	Whole fruit with a handful of nuts
Plain pasta	Pasta with chicken or lentils and vegetables
Crackers alone	Crackers with hummus or cheese
Sugary cereal	Oats with Greek yoghurt and berries

Build your plate

A practical template for most meals:

• Half the plate: vegetables or salad (fibre, volume, nutrients)
• A quarter: protein such as eggs, fish, chicken, tofu, beans or Greek yoghurt
• A quarter: high-fibre carbohydrates such as whole grains, legumes, potatoes with skin or fruit
• A thumb of healthy fat: olive oil, avocado, nuts or seeds

A sample day

• Breakfast: Greek yoghurt with berries, oats and chia seeds, or two eggs with wholegrain toast and tomatoes
• Lunch: A grain bowl with brown rice or quinoa, roasted vegetables, chickpeas and a tahini dressing
• Snack: An apple with peanut butter
• Dinner: Salmon or tofu, a big serving of greens and a baked sweet potato
• If you want dessert: Have it after a meal rather than on an empty stomach

Front-load protein

Many people with PCOS find that a breakfast that includes protein keeps them fuller and reduces cravings later. Eggs, Greek yoghurt, cottage cheese, tofu or a protein smoothie all work.

About cravings

Cravings in PCOS are real, and partly hormonal. They aren’t a lack of willpower. Some things that help:

• Eat regularly. Long gaps followed by a big meal can make crashes worse
• Include protein and fibre at every meal
• Notice timing. Many people find cravings cluster in the days before a period
• Prioritise sleep. Short sleep increases hunger hormones

Logging cravings alongside your cycle for a month or two often reveals a pattern. Ovra shows which phase of your cycle cravings tend to appear in.

If weight loss is a goal

For people with higher weight, losing around 5–10% of body weight can improve cycles, androgen levels and insulin sensitivity. Any healthy eating pattern that creates a modest energy deficit can work. Choose the one you can sustain. Pair it with regular movement, and talk to your doctor or a dietitian about support, including medication where appropriate.

Weight isn’t the whole story, though. Eating well improves PCOS symptoms at any size.

What about supplements?

Inositol, vitamin D and omega-3s are popular with people who have PCOS. The evidence for most supplements is still limited. Read our guide to inositol, and check with your clinician before starting anything, especially if you’re trying to conceive or take other medication.
