L-carnitine, also known as L-carnitine, is a substance similar to amino acids. Functionally speaking, under normal circumstances, the main function of L-carnitine is as a "porter" of fat, which sends fatty acids into the mitochondria of cells and burns them to generate energy. As a carrier, L-carnitine transports our fat to mitochondria in our cells. The combustion and decomposition of fat is such a process. First, fat is brought to mitochondria, and then oxidized and decomposed in mitochondria. Finally, after oxidative decomposition, the energy generated can supply the needs of our bodies in this form. Therefore, when there is a considerable amount of L-carnitine in our body, it does delay our fatigue to a certain extent, which is a mechanism and principle of how L-carnitine can help us lose weight. In fact, you can pay attention to weight loss products. L-carnitine is added to many weight-loss products, but we take it in the form of drugs through external supplementary sources. Of course, you can't rely entirely on L-carnitine to lose weight. L-carnitine cooperates with exercise and running, so it is recommended to exercise for more than half an hour, because carnitine mainly accelerates fat consumption, mainly consumes sugar in the early stage of exercise, and consumes more fat after half an hour, so it is best to exercise for more than one hour. Exercise is mainly aerobic exercise, such as running, brisk walking and skipping rope. It can be said that L-carnitine is more suitable for exercise and can also promote fat burning. What is L-carnitine? It is very helpful for us to lose weight to some extent. We can lose weight through L-carnitine and exercise.
