Eat not much or fat may be because the body’s metabolism is slower. The human body’s metabolism is mainly based on sweating to cool down, the process of fat metabolism will be accompanied by a large amount of heat release, the body will be more hot, the body automatically adjust after the fat metabolism will slow down. It is also possible to eat a lot of food with particularly high sugar content, the metabolism of sugar is a big project for the kidneys, did not have time to metabolize the sugar stored in the body, and the concentration of sugar in the body has a certain range, when the sugar is too high, the body will store water to dilute, and this is when edema occurs. Many times there is not a lot of body fat, just “swollen”. May also be because of the lack of exercise, the body does not metabolize the food eaten out will appear obese. May also be more body fat than others, and gastrointestinal absorption function is good, eat a little has been all absorbed, so easy to fat.
