If you want to lose weight healthily, you must first know why your body is obese, and then you can solve the obesity problem from the root. Obesity is because the energy contained in the food you eat greatly exceeds the energy consumed by your daily life and exercise. The inexhaustible energy is converted into fat and stored in your body. After a long time, more and more fat will make you fat. Therefore, to lose weight fundamentally, it must be that eating consumes less energy than daily life and exercise. Insufficient energy needs to be supplemented by decomposing the fat stored in the body. Every day, if there is less and less fat in your body, you will lose weight. At the same time, the more energy your body consumes every day, the faster you lose weight. There is a technical term called energy gap, which means that the greater the energy gap, the faster you lose weight. Exercise is to increase the energy consumed by the body. The greater the energy gap, the faster you lose weight! As the saying goes, losing weight means keeping your mouth shut and holding your legs. This is also a fact.
