Nutrition Science for PCOS Blog & Resources 

If you have PCOS and irregular periods, working out whether you are ovulating can feel confusing. Your tracking app may predict a different fertile window each month, ovulation tests may stay positive for several days, and having a bleed does not always confirm that an egg was released. The clearest approach is to understand what each sign can, and cannot, tell you. Changes in cervical mucus and a rise in luteinising hormone (LH) can suggest that ovulation may be approaching.

If you have PCOS (now known as PMOS), it is easy to feel that you should be taking a long list of supplements. Omega-3, vitamin D, magnesium, NAC, curcumin and probiotics are all promoted online for reducing inflammation, often with confident claims and very little explanation of who they may help. The reality is more nuanced. Some supplements have been studied in women with PCOS and may influence certain inflammatory or metabolic markers. However, no supplement has been show

Perhaps you haven't dramatically changed the way you eat, yet your clothes feel tighter around your middle. Maybe you're experiencing stronger cravings than you used to, feeling hungrier between meals or finding that maintaining your weight takes much more effort. It can be particularly frustrating when you're eating reasonably well and don't feel that yo

Have you reached your 30s or 40s and feel like your body has suddenly changed? Perhaps you haven’t dramatically changed what you eat, yet the weight seems to creep on more easily. The methods that worked in your twenties no longer make much difference. You’re feeling hungrier in the evenings, your energy dips during the day and losing weight feels like an uphill battle. If this sounds familiar, you’re certainly not alone. Many women with PCOS tell me they feel as though they’

If you're trying to eat well with PCOS, lunch can often be the meal that lets you down. Perhaps you throw together a quick salad, grab a supermarket sandwich or skip lunch altogether because you're busy. It might seem like the healthier option at the time, but if your lunch doesn't contain enough protein, fibre and healthy fats, there's a good chance you'll be reaching for biscuits, chocolate or crisps by mid-afternoon. Read this post to learn more about why fibre and gut hea

What Should You Eat in a Day With PCOS? One of the most common questions I hear is: "What should I actually eat in a day with PCOS?" After scrolling through social media, it's easy to feel confused. One person says to cut out carbohydrates. Another recommends intermittent fasting. Someone else claims dairy is the problem. The reality is that there is no single perfect PCOS diet. In my experience, most women benefit from stepping away from restrictive food rules and focusing o

When the weather is warm or you've been busy all day, the last thing many of us want to do is spend an hour standing over the cooker. But if you have PCOS, skipping meals or relying on toast, cereal or snack foods can leave you feeling hungry again within a couple of hours, making afternoon energy dips and evening cravings much harder to manage. Eating well doesn't have to involve complicated recipes or meal prep marathons. With a few simple ingredients in your fridge, you ca

If you have PCOS and often feel: exhausted after work constantly hungry in the evenings stuck in a cycle of snacking after dinner out of control around food at night frustrated that you “eat well all day” then overeat later your evening meal patterns may be playing a bigger role than you realise. Many women with PCOS spend the entire day: rushing working through lunch relying on caffeine eating very little trying to “be good” with food Then by evening: hunger feels intense cr

There is no separate official protein requirement for women with PCOS. As a starting point, UK adults need around 0.75g of protein per kilogram of body weight each day. Some women may benefit from approximately 1.0–1.6g per kilogram, depending on their activity, strength training, appetite, age and weight-management goals. You do not need to reach a perfect number or track every gram. Including a satisfying source of protein at each meal is often a more practical way to suppo

If you've been diagnosed with PCOS/PMOS, you've probably been told you need to "balance your hormones." The problem is that nobody really explains what that means. Hormones don't work in isolation. They're influenced by many different systems throughout the body, including your metabolism, gut, immune system and nutrient status. This is why there isn't one magic food, supplement or diet that balances hormones overnight. Instead, small, consistent nutrition and lifestyle habit

When women with PCOS try to improve their nutrition, fibre is often overlooked. Most conversations online focus on: cutting carbohydrates avoiding sugar fasting or following restrictive food rules. But one of the most supportive nutrients for PCOS may actually be: fibre. Fibre plays an important role in: blood sugar balance appetite regulation digestion gut health fullness after meals and overall metabolic health. Many women with PCOS are not eating enough fibre consistently,

If you've ever looked at healthy recipes online and thought, "I don't have time for all of that," you're in the right place. Many women with PCOS assume eating well means preparing different meals every day, buying expensive ingredients or following complicated meal plans. In reality, one of the simplest ways to support your overall health is to gradually include a wider variety of foods in your diet. This doesn't mean completely changing how you eat. It means making small ad
