Comparison of Intermittent Fasting and Caloric Deficit for Weight Loss in Women With Polycystic Ovarian Syndrome

Intermittent Fasting and Polycystic Ovarian Syndrome

Time restricted feeding (TRF) has been emerging as a potential weight loss strategy that avoids major dietary changes but achieves strong effects. It also improves insulin sensitivity through increased human growth hormone. This effect helps to improve the root cause of weight gain and has additional benefits for women with PCOS.
