Living with PCOS: food, movement and weight

There’s no single best diet for PCOS. The international guideline found no evidence that any one mix of foods works better than another. That goes for hormones, fertility, metabolism and mental health. Start with food you enjoy and can afford to keep eating.

PCOS now has a new name: polyendocrine metabolic ovarian syndrome (PMOS). Both names mean the same condition. This article uses PCOS because it’s the name you may already know.

Food without a special rulebook

Healthy eating is part of PCOS care, but the guideline recommends a flexible approach that suits what you like and what you want to achieve. It warns against diets that cut out too much food or lack a balance of nutrients. You don’t need a named PCOS eating plan.

Talk about what makes eating well hard. The guideline asks clinicians to think about money, culture, physical limits and mental health when they talk about food. If you need more support, your clinician can think about referring you to someone with the right training.

At an appointment, pick the hardest part. It might be planning meals around shifts, the cost of food, or advice that clashes with what your household eats. Ask for a change that fits that situation. Say if a plan feels too complicated or doesn’t appeal to you.

The NHS recommends a balanced diet and regular exercise. WHO says these habits matter with PCOS even if they don’t lead to weight loss. The international guideline also recognises benefits for general health and quality of life, rather than measuring progress only by weight.

Movement that fits into your week

No type or intensity of exercise has been shown to be best for PCOS. Activity can include walking or cycling to get around, housework, games and planned exercise. The guideline says some activity is better than none. Swapping time sitting down for any kind of movement can help your health.

For adults aged 18-64 years, the guideline gives a general health target. This is 150 to 300 minutes of moderate activity or 75 to 150 minutes of vigorous aerobic activity a week, or a mix of the two. It also recommends activities that strengthen muscles on two days a week that aren’t next to each other. These goals are for the whole population. Your own plan needs a conversation about you.

If you’re not sure where to start, use these goals to start a conversation. You could ask how to fit movement around pain, disability, caring for others, or something you already enjoy. Say what you’d like to do.

A health plan does not have to centre on weight loss

Managing your weight can be part of care if that’s what you want. The guideline also supports weight-inclusive care. This means making changes for your health without trying to lose weight. It calls for good care at every weight, including checks and treatment.

The guideline accepts that weight stigma (being judged for your weight) in healthcare causes harm. It advises clinicians to ask your permission before talking about or measuring your weight. If you’re asked to be weighed, ask why they need to know and how it will change the plan.

You can say clearly what you’d prefer: “I’d like to focus on food, movement and symptoms without a weight-loss goal.” Or ask for support with your weight if that’s what you want. Agreeing goals together is part of the recommended approach.

Sleep and eating difficulties need their own attention

Sleep apnoea is more common with PCOS, whatever your body size. It means your breathing stops and starts many times while you sleep. If you snore and also wake up unrefreshed, feel sleepy in the day or feel very tired, ask to be checked.

The guideline also asks clinicians to think about eating disorders and unhealthy eating patterns at any weight. This matters especially when they talk about lifestyle or weight. If a plan leaves you struggling with eating, bring it up. If an eating problem is suspected, the guideline recommends a check and the right support.

Asking for practical support

Book a GP appointment in the UK, or see your doctor in the US or elsewhere, for eating problems or the sleep symptoms described above. You can also ask for help shaping a food and movement plan around your health and situation.

Bring a short account of what you’ve tried and what got in the way. Ask which goal you’ll work on, who can help with it and when you’ll review it together. If talk about weight has made past appointments hard, say so at the start.
