Polycystic ovary syndrome (PCOS) is a hormonal disorder common among women of reproductive age. Women with PCOS may have infrequent or prolonged menstrual periods or excess male hormone (androgen) levels. The ketogenic diet aims to lower insulin levels and can induce weight loss which is helpful for women with PCOS. It also improves insulin sensitivity, aids weight loss, manages hunger, and improves the PCOS hormone profile. Losing weight on a keto diet becomes easier and is one of the many reasons that women start a keto diet. You see, if your body is well adapted to burning fat for energy, it can then more readily use your own fat stores for energy instead of all the glucose it would normally use.
