In reality, our body will use fat to store excess protein or carbohydrates in the form of triglyceride molecules. Biologically, the "fat" that people expect to lose is actually these triglycerides stored in cells.
This molecule contains three components: carbon, hydrogen and oxygen. The process of losing weight is actually to "decompose and oxidize" the triglyceride molecules in the body.
When triglyceride molecules are oxidized, this process consumes many oxygen molecules and produces carbon dioxide and water, as well as other wastes.
Through a series of scientific formulas, it can be calculated that to "burn" 10 kg of fat, an individual needs to inhale 29 kg of oxygen, and this chemical reaction of burning fat will produce 28 kg of carbon dioxide and 1 1 kg of water.

Say goodbye to fat scientifically
The concept of scientific fat reduction cannot escape a kind of exercise-aerobic exercise. Because the process mentioned before that fat is converted into energy and finally into carbon dioxide and water, it is inseparable from aerobic exercise.
Simply put, aerobic exercise is a form of exercise that keeps the heart rate at a certain level, that is, the bull's-eye rate, and the exercise time is not less than 20 minutes. In contrast to this concept, long-distance running, brisk walking, cycling and other sports can all fall into this category.
But basketball, volleyball and other ball games are not aerobic exercises. Because the latter does not always keep the heart rate at the same level. Only when the intensity and time of fat reduction meet the requirements at the same time can the body fat be mobilized.
At the beginning of exercise, the body consumes glycogen stored in muscles. With the increase of time, glycogen participation gradually decreases, and fat becomes the main energy source. Therefore, the process of reducing fat needs to be adhered to. "
Wang Qirong further explained that during aerobic exercise, if only muscle glycogen provides energy, the maximum rate of aerobic exercise can only be maintained for less than 60 minutes. Exercise muscles must absorb and utilize blood sugar and plasma free fatty acids.
Fat will only participate in energy supply when you exercise at low intensity for a long time. The fat mentioned here refers to triglycerides. Moreover, the longer the exercise time, the smaller the intensity, and the greater the proportion of energy supplied by fat oxidation.
The complete oxidation of fat in vivo is bound to involve sugar metabolism, because when fat is catabolized, its fatty acids are further oxidized and degraded into acetyl-CoA, and acetyl-CoA must be combined with oxaloacetic acid, an intermediate product of sugar oxidation, before it can enter the aerobic metabolic pathway and be completely oxidized.
