Does L-carnitine cause weight regain after weight loss?

L-Carnitine, as an auxiliary weight-loss substance, generally does not cause significant rebound weight gain. However, this does not mean that the importance of diet and exercise can be ignored after taking L-Carnitine. The primary function of L-Carnitine is to promote the oxidation and breakdown of fat by facilitating its entry into the mitochondria, thereby accelerating fat metabolism. This process indeed helps reduce body fat content and consequently lower body weight. To achieve optimal weight-loss results, it is necessary to combine L-Carnitine supplementation with a balanced diet and moderate exercise. Only through the combined effects of these factors can body weight be effectively reduced and weight rebound prevented. However, excessive intake of L-Carnitine may lead to certain adverse reactions, such as diarrhea and loss of appetite. Therefore, L-Carnitine should be taken strictly according to the recommended dosage, and attention should be paid to the body's response.
