Because of the hormone balance before menstruation, progesterone rises, water retention in the body increases, breasts increase and endometrium thickens, which leads to the obvious weight gain of women in the first few days of menstruation. After menstruation, due to the decrease of hormone level, breasts shrink, endometrium and blood are discharged, water in the body decreases, and weight should be reduced. This decline may make up for the weight gain caused by eating, so the legendary "nothing will make you fat." Tip: If you don't eat indiscriminately, you will lose one or two pounds or even two or three pounds after menstruation.

Menstrual calorie consumption is twice as high as usual?

At this point, let's take a look at the expert's research results: "In the article published by Horton and other researchers in 2002, the menstrual cycle is divided into early follicular phase (low estrogen and progesterone levels), middle follicular phase (high estrogen and progesterone levels) and middle luteal phase (high estrogen and progesterone levels). In 90 minutes of moderate-intensity physical activity, the level of energy substance oxidation and glucose utilization of normal-weight women are between these three. exist

In the article published on 20 1 1, researchers such as Vaiksaar divided menstrual cycle into follicular phase and luteal phase, and found that female rowers' energy consumption, oxygen consumption level, exercise and resting heart rate level, energy substance oxidation level and lactic acid level had nothing to do with menstrual cycle during dynamometer exercise at 1 hour. Tip: The popular explanation is that the researchers found three women at different stages of the menstrual cycle for comparative experiments. According to the actual measurement, there is no obvious difference between women's calorie consumption and metabolism in different physiological periods, so there is no such phenomenon as "menstrual calorie consumption is twice as high as usual".

Poor digestion and absorption during menstruation

Eating high-calorie food won't make you fat?

After ovulation (menstrual day 14), anorexia, dyspepsia and decreased absorption function may occur due to the effect of progesterone. If the first half of the sentence "menstrual indigestion" refers to this period, it is possible. But the second half of the sentence is very problematic. During the above period, progesterone in women's bodies did not rise too much (much less than during pregnancy), and it would not be so obvious. Eating too much will make you fat. "The decline in absorption function is not without absorption. If you eat too many calories, it will also be converted into fat and stored. At any stage, don't overeat by thinking that you won't get fat if you don't absorb it well. "

Within two weeks after the physiological period

This is the best time to lose weight.

Generally speaking, women's menstruation takes 28 days as a cycle, and the menstrual cycle is divided into menstrual period (menstrual period 1-6 days), late menstrual period (menstrual period 7- 13 days), inter-menstrual period (menstrual period 14-20 days) and pre-menstrual period (menstrual period).

2 1-28 days) is divided into four periods. Leptin concentration changes with the change of menstrual cycle, with the lowest in menstrual period and rising gradually in the later period. Leptin began to rise on the 7th day of menstruation, and reached the highest level during ovulation (about 65438+ 4th day of menstruation), and gradually decreased in the prophase until the lowest level during menstruation. Therefore, the best time to lose weight during menstrual cycle is from the 7th day to the 20th day. The best time to lose weight is the seventh day after menstruation, that is, when menstruation has just come. About two weeks after the physiological period, due to hormonal changes, appetite declines and metabolism accelerates, which can be said to be an excellent golden moment to lose weight. At this time, correct diet control and active exercise plan will get twice the result with half the effort.
