What the latest research says about diet, supplements and lifestyle for managing PCOS without medication.
Recent meta-analyses confirm that diet and lifestyle changes can produce clinical remission of PCOS in 50-70% of women within 6-12 months - even without medication. The key is matching the intervention to the woman.
Low-glycaemic Mediterranean-style eating, daily strength training, 7-8 hours of sleep, stress management and selective use of supplements (inositol, vitamin D, omega-3, magnesium). Together, these produce better results than metformin alone in many trials.
Extreme low-fat diets. Crash calorie restriction. Generic "PCOS diets" sold online. Most "detox" teas and miracle supplements. Soy in extreme quantities. These either do not help or actively harm.
Most studies show first cycle changes by week 8-12 of consistent lifestyle change. Full restoration (regular monthly cycles) typically takes 4-6 months. Fertility outcomes improve dramatically once cycles regularise.
If symptoms are severe, fertility is time-critical, or lifestyle alone has not moved the needle in 3-4 months, metformin or other medications can be added under your gynaecologist's guidance. Diet still does most of the work.
