The mature genetic code of girls must have enough fat to be triggered. Too little fat and delayed trigger of code reduce estrogen secretion, which leads to many gynecological diseases related to menstruation. Fat is closely related to menstruation. Teenage girls need at least 65,438+07% body weight to have their first menstruation, and at least 22% body fat to maintain a normal menstrual cycle. If girls blindly go on a diet and resist fatty foods, they will consume a lot of protein and fat in their bodies, and then estrogen deficiency will inevitably lead to delayed menarche or menstrual disorder, and even amenorrhea may occur in severe cases. Young unmarried women need to store a certain amount of fat in their bodies to prepare for future fertility activities.
