It is possible to temporarily lose weight simply by not eating or exercising, but it is normal to rebound after a single diet returns to normal. If combined with proper exercise (such as jogging and aerobic exercise), it can consume excess calories, improve metabolic rate, and make people fit without rebounding.
In the process of losing weight, it seems that there is less excess fat on the body, but in fact, the number of fat cells has not decreased, but the fat volume has become smaller. Therefore, after temporarily losing weight through dieting, the volume of fat cells will still be' fat' after eating under normal diet. What's more, blindly dieting to lose weight will also reduce the metabolic rate of the human body, and the reduction of metabolic rate will consume less calories, so people will gain weight more easily.
