The available evidence shows that moderate carb restriction is effective in treating any female hormonal problems that might be driving weight gain. In this study of women with PCOS, for example, 30% of calories from carbs worked better than 55% of calories. On the other hand, an extremely low-carb diet is not necessarily the answer either: especially for women, extreme carb restriction can cause problems of its own, including hormonal dysfunction, amenorrhea (loss of normal periods), and infertility. Sweet potatoes are not the enemy! You can eat 1-2 starchy tubers (potatoes or sweet potatoes) every day and still be well under 30% of calories from carbs.
Probably. If you have overweight or obesity, your risk for many health problems is higher than that of women who are at a normal weight. Even a small amount of weight loss can lower your risk for or even prevent health problems like diabetes and heart disease. Calculate your body mass index (BMI) to see whether you’re at a healthy weight. If you have overweight or obesity, start by making small changes to your eating habits and getting more physical activity.
