PCOS can attract a huge amount of nutrition advice, much of it restrictive, contradictory or presented as a guaranteed route to “balancing hormones”. We wanted a calmer, more practical conversation.
We spoke with women's health nutritionist Kirsten Oddy about food, fertility, movement and the habits she believes are most useful for people living with PCOS.
Meet Kirsten Oddy
Kirsten is a women's health nutritionist who supports clients with hormonal and reproductive health concerns. Her approach is rooted in sustainable habits rather than rigid food rules.
That matters with PCOS because the condition looks different from one person to another. Nutrition can support general metabolic and reproductive health, but it should sit alongside appropriate medical assessment and treatment rather than being sold as a cure.
Our Conversation with Kirsten
What nutrition myths do you see most often around PCOS?
Kirsten regularly sees people arrive believing they need to remove gluten, dairy, carbohydrates or multiple food groups. Her advice is not to restrict foods without a clear reason. A more useful starting point is meal quality, regularity and whether the overall pattern is realistic enough to maintain.
What does a supportive eating pattern look like?
Kirsten recommends building meals around protein, fibre, vegetables, wholegrains and healthy fats. That can help meals feel satisfying and supports general metabolic health without turning food into a complicated set of rules.
For fertility, good nutrition supports the body broadly, but no individual food can guarantee improved egg quality, implantation or pregnancy.
Are there easy swaps that do not feel like a diet?
Her examples are deliberately ordinary: swap refined grains for wholegrain versions where you enjoy them, add lentils or beans to meals, include oily fish if it suits your diet, make breakfast more protein-rich, add an extra portion of vegetables and consider replacing a second or third coffee with a lower-caffeine drink if caffeine is affecting sleep or anxiety.
What about exercise?
Kirsten encourages regular movement rather than punishing exercise. Walking, resistance training and cardiovascular activity can all have a place. The best plan is one that fits your health, preferences, recovery and current fitness level.
How important is sleep?
Very. Sleep affects energy, appetite and stress, and poor sleep can make day-to-day symptom management harder. Persistent snoring, waking unrefreshed or marked daytime sleepiness deserves medical attention rather than simply being blamed on hormones.
Kirsten's Practical Starting Points
- Build meals around protein and fibre rather than cutting out entire food groups.
- Choose carbohydrates you enjoy and can pair with protein, vegetables or healthy fats.
- Make movement regular and realistic instead of using exercise as punishment.
- Protect sleep and notice whether caffeine or late nights are making symptoms harder to manage.
- Track symptoms if it helps you identify patterns, but do not use a tracker to self-diagnose.

PCOS, Fertility and the Bigger Picture
PCOS is one possible cause of irregular ovulation, but fertility is affected by many factors and both partners may need assessment. If you are trying to conceive and cycles are very irregular, or you have been trying for the recommended period for your age and circumstances, speak with a GP or fertility professional.
Nutrition can support health before and during fertility treatment, but it should not become another source of blame. A good plan should leave room for medical care, medication, fertility treatment and the realities of life.
More from Kirsten
Kirsten's message is refreshingly straightforward: you do not need a perfect diet to support your health. Consistent, nourishing habits are usually more useful than an extreme reset you cannot sustain.
