L-carnitine weight loss principle The metabolic process of fat has to go through an obstacle, which is the mitochondrial membrane. Mitochondria can burn fat, release energy and be consumed by the body, but long-chain fatty acids can't pass this obstacle. L-carnitine plays the role of a porter! Carry the long-chain fatty acids out of the shield bit by bit and send them to mitochondria for further oxidation! L-carnitine is just a vehicle, and how much fat is consumed does not depend on L-carnitine. It's like the bricks that Gai Lou needs are transported by car, but how many bricks Gai Lou consumes does not depend on the number of cars, but on the size and structure of the building. Simply put, if the amount of exercise (energy consumption) is not large and the fat consumption is not much, just increasing L-carnitine will not increase the oxidation function of fat, so it will not help to lose weight. Under normal circumstances (the amount of exercise is not very large), the human body will synthesize enough L-carnitine by itself, and there will be no problem of L-carnitine deficiency. Only when the amount of exercise is large, such as athletes or bodybuilders, the energy consumption per unit time is large, and the "flow" of fat oxidation energy supply is large, it is possible (supported by many research reports, but also denied by some research reports) that the synthesis of L-carnitine is "relatively insufficient". At this time, taking extra L-carnitine, expanding the scale of the transport fleet (carrier) and transporting more bricks (fatty acids) to the construction site (mitochondria) in a unit time are obviously beneficial to the oxidation and consumption of more fat.
