The following is the data of the female physiological cycle in a year, which combines the physiological cycle with our weight loss and is divided into four cycles: deceleration period, deceleration period, stop period and menstrual period. A week or so, estrogen in the body began to decrease, and progesterone (also known as progesterone) began to increase, thickening the endometrium. At this time, under the action of progesterone, the skin will become greasy, prone to acne, chest pain, body fat accumulation, weight gain, abdominal distension and a series of PMS. At this time, it is also the cessation period of weight loss, and the weight loss plan will stop, which is harmful to the body.

These three cycles and menstrual period constitute the whole physiological cycle of women, so we can see at a glance that in a month's time, only the rapid decline period and the slow decline period are suitable for weight loss, which is a relatively scientific weight loss period. About 15 days.
