Women in Central and South America are usually regarded as a symbol of health. Compared with Asian women, women in Central and South America have higher levels of female hormones because of their different eating habits and genes. Japanese female hormone research experts say that these women's waists are made of hormones. Estrogen can change the distribution of fat. Yao Mi Ryoko, director of the Health Management Department of Kanto Central Hospital, said that estrogen in female hormones will help the body store subcutaneous fat, which will mostly accumulate in the lower body and chest. The main purpose is to make fertile women cultivate a body suitable for pregnancy. According to the X-rays of waist and abdomen of 20-year-old and 50-year-old women, the abdominal fat thickness of young women is about one-fifth of that of menopausal women, so their waistlines are much slimmer. Women must constantly provide fetal nutrients during pregnancy and be responsible for feeding fetal breast milk after delivery, so they need to store a lot of energy in their bodies. Skin is the largest tissue in the human body, so it is more suitable for storing fat for burning than internal organs. It is easy to lose weight according to the physiological cycle, but it is not easy to regain weight. Professor Kawakawa, an emeritus professor at the University of Tokyo, also said that there were experiments in the past to investigate the relationship between estrogen and fat burning. The experimental results show that the fat burning rate is completely different before and after the physiological period. The most suitable time for women to lose weight by exercise is after menstruation and before ovulation. This way of losing weight in line with the physiological cycle is not easy to gain weight. Professor Hu Chuan mentioned that due to the highest concentration of estrogen in the body at this time, it is prone to the physiological phenomenon of loss of appetite and rapid heartbeat. After comparing the fat burning status of women in the gym, it can be found that after the same amount of aerobic exercise and weight-bearing training, women in the week before ovulation can reduce their body fat by 0.57%, which is 1.5 times more than women in the week after ovulation. Because the production of estrogen in human body is limited, Professor Song Yongjia Shizi from Fujita Health University said that exercise habits combined with the intake of soybean milk, tofu and natto can also provide beneficial bacteria in the intestine to produce equol. When the concentration of equol in the body rises, it can play a role similar to estrogen. With protein in soybean, it can help the body build muscles and forge a body that is not easy to gain weight and has high basal metabolism. Professor Song Yong suggested that the intake of soybean food should be one piece of tofu or 200ml of soybean milk every day. As long as you insist on eating, the beneficial bacteria responsible for producing equol in the intestine will increase continuously. Besides losing weight, you can also beauty beauty and improve your memory.
