Polycystic Ovary Syndrome (PCOS) affects approximately 1 in 10 women of reproductive age in the UK. It’s characterised by hormonal imbalances, insulin resistance, irregular periods and often weight gain. Emerging research suggests the ketogenic diet may offer significant benefits for women with PCOS.
Insulin resistance is present in up to 70% of women with PCOS. When cells don’t respond properly to insulin, the pancreas produces more insulin, which in turn stimulates the ovaries to produce excess androgens (male hormones). This disrupts ovulation and causes many PCOS symptoms.
By dramatically reducing carbohydrate intake, keto lowers blood glucose and insulin levels. This directly addresses the root cause of insulin-driven PCOS. Studies have shown that low-carb diets can: improve insulin sensitivity, restore menstrual regularity, reduce androgen levels, promote weight loss, and improve fertility markers in women with PCOS.
Beyond insulin, keto can positively influence other hormones relevant to PCOS. Reducing inflammation (which keto does through lowering blood sugar and oxidative stress) may improve LH/FSH ratios and support healthier ovarian function. Always work with your GP or gynaecologist when making dietary changes for PCOS management.
Focus on anti-inflammatory keto foods: fatty fish, leafy greens, avocados, olive oil, nuts and seeds. Avoid processed keto products with artificial sweeteners. Get regular moderate exercise to further improve insulin sensitivity. Explore our keto breakfast recipes and keto desserts for hormone-friendly meal ideas.
