Eat less but still fat because the body’s basal metabolic rate is too low, can be changed in several ways, the most important is to improve the body’s metabolic rate, and adjust the body’s acid-base balance, adjust the body’s endocrine and environmental systems, can do the following: First, adhere to aerobic exercise, daily aerobic exercise at least 30-45 minutes or more. Exercise should not be too strenuous, aerobic exercise to fully absorb air, exhale carbon dioxide, increase lung capacity as the main mode and method of exercise, it is best to control the heart rate at about 120-140 times / min, to be slightly hot body sweating, can achieve the effect of improving the basal metabolic rate. Second, can be appropriate muscle exercise, large muscle groups, such as biceps, biceps femoris, gluteus maximus and other exercises, can promote the improvement of the recent basal metabolic rate. Third, drugs can be taken to improve the absorption and digestive function of the gastrointestinal tract, but also take a combination of vitamins, trace elements and other drugs to mediate the endocrine system and improve the internal environment. Eating less but still fat belongs to an endocrine disease of low basal metabolic rate, which can be regulated by the above means.
