The menstrual cycle isn't the cause of weight changes, it's just a bystander, explains Arias. The menstrual cycle does not directly impact weight loss or gain, but there may be some secondary connections. On the list of premenstrual syndrome (PMS) symptoms are changes in appetite and food cravings, and that can affect weight. Studies show that women tend to crave foods high in fat and carbohydrates during specific phases of the menstrual cycle; women also tend to take in more calories during these phases.
