You must pay attention to losing weight during menstruation. The answer you mentioned is as follows: 1. Remember to drink a large glass of warm water when you get up in the morning-detoxification 2. Don't eat too much every meal every day, eat more times (at that time, I ate five meals a day, and the amount was not large). I will definitely eat a fruit before meals to make my stomach feel full. I refuse to eat anything after six in the evening. You can go to yoga if you can.
