The so-called menstrual weight loss is to divide the weight loss effect into four stages by physiological cycle: 65438+ 0-7 days from menstrual period. These days, because the secretion of estrogen and lutein in the body is very low and the metabolic ability is poor, the whole body is in an inactive state, which is easy to cause water retention and edema. So during this time, some people may gain weight. 7- 14 days after menstruation, starting from the seventh day after menstruation, the estrogen in the body will start to climb, which is the golden period of weight loss. As long as you do a good job in diet control during this period, you can generally see good results. But as far as principle is concerned, the obvious effect of this period is mostly due to the discharge of water caused by water retention during physiological period, so the weight date at this stage will drop by 3-4 kg. After menstruation 14-2 1 day is the ovulation period. At this stage, the metabolic rate will be slower and slower, the weight will not be easily lost, and the appetite will become better.
