The elimination of adipose tissue stored in the body is essentially that fat is oxidized and decomposed into CO2 and H2O in mitochondria of various tissues and cells, and at the same time, the released energy is converted into other required energy forms (such as mechanical energy of exercise). Fat can be decomposed to release energy only through oxidation reaction. On the other hand, the stored fat will only be passively utilized and decomposed when the human body needs more energy than usual (such as exercise).
Extended data:
The process of fat metabolism is like buying gold to preserve its value. People exchange inexhaustible money for gold to preserve their value, and then exchange gold for money when they need it. Gold is just a form of currency preservation.
When the intake of energy-supplying substances exceeds the energy consumption, the excess part can be stored as synthetic fat, and when the intake of energy-supplying substances is insufficient, the stored fat is used for decomposition and energy supply. In this process, fat is only a form of energy conservation. Once the foreign oil and water is very fat, not only does it not need to use the stock fat, but it will also add new fat to the stock, and finally it will form fat.
