Generally speaking, L-carnitine has a certain weight loss effect. Specifically, the main physiological function of L-carnitine is to promote the conversion of fat into energy. Therefore, taking L-carnitine can reduce fat and weight without reducing water and muscle. However, to achieve this goal, it is inseparable from the amount of exercise. It can be seen that the effect of L-carnitine on weight loss is a prerequisite, that is, the amount of exercise, because if there is no exercise, the fat consumption in the human body is not much, and only increasing L-carnitine will not increase the oxidation function of fat, so it has little effect on weight loss. The above are some contents about whether L-carnitine is effective in losing weight. Generally speaking, if L-carnitine wants to think of effective weight-loss effect, then the amount of exercise must be sufficient, otherwise only increasing L-carnitine will not achieve satisfactory weight-loss effect.
