In principle, the only correct way to consume fat is to convert it into energy through aerobic oxidation in the body. This is an internal metabolic process. Normal exercise such as running and swimming can promote aerobic transformation. Aerobic oxidation cannot be achieved by applying external forces such as vibration in vitro. In addition, fat itself has no contraction function and does not produce energy itself. It is either "crushed" or "less shaken" and consumes fat molecules.

Aerobic oxidation: refers to the decomposition of sugar, fat and protein into carbon dioxide and water with the participation of oxygen, and releases a lot of energy.

A lot of vibration to lose weight is actually just a heat transfer process. For example, vibration has a heating function to raise the local temperature; The vibration of the belt produces heat energy, which is then transferred to the stomach, causing local fever and sweating at the waist. Just like a sauna, people sweat through external heat, at most, they lose water and do not consume fat, so it is impossible to lose weight.

When active exercise consumes fat, people can feel that they are working hard, for example, when running, they will feel the contraction of leg muscles; You will also feel energy consumption, such as getting hot and sweating. This kind of fever is systemic, not local. Judging from some physical indicators, people's pulse will accelerate, breathing will become faster, blood pressure will rise, and so on. In this state, fat can be consumed healthily. The difference between passive sports and active sports lies in whether the athletes contribute. Active exercise requires one's own efforts, and athletes can feel obvious muscle contraction; Passive athletes generally don't make their own efforts, or only make a little effort, and rely on machinery to drive sports (not to say that there is no active sports with mechanical assistance, many sports equipment are active sports, and the key is whether to make efforts).
