Polycystic ovary syndrome (PCOS)
PCOS frequently combines cycle disturbances, signs of hyperandrogenism and insulin resistance. Nutrition does not treat the syndrome, but it acts on two of its main drivers: insulin sensitivity and the inflammatory background.

Understanding PCOS: insulin, inflammation, hormones
In most patients, insulin resistance sustains hyperinsulinaemia, which stimulates ovarian androgen production. Low-grade inflammation and a hormonal imbalance disturbing ovulation are often added to it. These three mechanisms feed each other, which is why nutrition has a measurable effect on symptoms.
- Insulin resistance: cravings, post-meal fatigue, abdominal weight gain
- Low-grade inflammation: fat quality, fibre and polyphenol intake
- Hormonal imbalance: irregular cycles, acne, excess hair growth
- Diagnosis remains medical (gynaecologist, endocrinologist): dietetic follow-up complements it
The nutritional pillars of PCOS
No dramatic exclusion is required. The work focuses on meal glycaemic load, fat quality and steady intake across the day. These three levers reduce insulin peaks and, for many patients, the intensity of cravings.
- Low glycaemic load: carbohydrates spread out, paired with protein and fibre
- Omega-3 / omega-6 balance: oily fish, rapeseed, walnuts; limit omega-6-rich oils
- Craving management: protein-rich breakfasts, complete meals, no skipped meals
- Regular physical activity, especially resistance training
Realistic goals of the support
Goals are set with you and reviewed at each consultation. They focus on observable markers — cycle regularity, energy, lab results monitored by your doctor — with no promise of outcome, as every situation differs.
- Improve insulin sensitivity and limit reactive hypoglycaemia
- Support cycle regularity, alongside gynaecological follow-up
- Gradual weight management where relevant, without restrictive dieting
- Prepare a pregnancy project nutritionally, complementing medical care
What belongs to your physician
Diagnosis, tests and medical treatment remain your doctor's responsibility. Dietetic support adapts to them and, with your agreement, a report is sent to your doctor.

Frequently asked questions about PCOS
The practice neither sells nor commercially recommends supplements. Some supplements are discussed in the scientific literature, but their indication, dosage and monitoring are your doctor’s decision, based on your lab results.
Current evidence does not justify systematically removing dairy. It provides protein and calcium. If digestive discomfort or skin symptoms occur, a targeted, temporary adjustment can be trialled and then reassessed.
The insulin resistance frequently associated with PCOS raises the risk of glucose intolerance and type 2 diabetes. Regular screening, prescribed by your doctor, is recommended; nutrition and physical activity are part of the prevention levers.
No. What matters is the amount per meal, the quality and the pairing with protein and fibre — not exclusion.
