Generally speaking, L-carnitine has a certain weight-reducing effect. Specifically, the main physiological function of L-carnitine is to promote the conversion of fat into energy. Therefore, taking L-carnitine can reduce body 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 the effect on weight loss is minimal. The above are some contents related to the question of whether L-carnitine is effective in losing weight. Generally speaking, if L-carnitine wants to play an effective role in losing weight, then the amount of exercise must be sufficient, otherwise just increasing L-carnitine will not achieve a satisfactory weight loss effect.
