Improves PCOS symptoms
Polycystic ovary syndrome (PCOS) is a hormonal disorder that can lead to excess male hormones, ovulatory dysfunction, and polycystic ovaries. A high-carbohydrate diet can cause adverse effects in people with PCOS, such as skin problems and weight gain.
There are not many clinical studies on the ketogenic diet and PCOS. One pilot study from 2005 examined five women over 24 weeks. The researchers found that a ketogenic diet improved several markers of PCOS, including:
- weight loss
- hormone balance
- ratios of luteinizing hormone (LH) and follicle-stimulating hormone (FSH)
- levels of fasting insulin
A different review of studies from 2019 found that a keto diet had beneficial effects for people with hormonal disorders, including PCOS and type 2 diabetes. However, they did also caution that the studies were too diverse to recommend a keto diet as a general treatment for PCOS.
