Ketogenic diet in women with polycystic ovary syndrome and liver dysfunction who are obese: A randomized, open-label, parallel-group, controlled pilot trial.

Aim: To evaluate the effect of a ketogenic diet (KD) in women with polycystic ovary syndrome (PCOS) and liver dysfunction who were obese.

Methods: Women with PCOS and liver dysfunction who were obese were enrolled in this prospective, open-label, parallel-group, controlled pilot trial, and randomly received KD (KD group) or conventional pharmacological treatment (Essentiale plus Yasmin, control group) in a 1:1 ratio for 12 weeks. The primary endpoint was the liver function markers.
