You can't lose weight without eating or drinking during menstruation. Not eating is just a temporary weight loss. Once you eat back, the rebound will be even greater. Moreover, menstruation is the most vulnerable time for women. If you don't eat it, imbalance will easily lead to changes in hormone levels in the body, which will indirectly lead to the possibility of irregular menstruation, and in most cases will delay the possibility of menstruation.

It is suggested to ensure regular diet, balanced nutrition and adequate sleep, especially during menstruation, so that the endocrine system is in a relatively normal state and menstruation is relatively normal.
