Are l-carnitine enriched drinks really effective in losing weight?
L-Carnitine is mostly used for weight / muscle gain, not weight loss. Increasing muscle mass will help a little at weight loss, but the real secret to loosing weight is a proper diet. There is only one rule: Take in less than you burn (in calories). Additionally, it is beneficial to take in nutritious foods, rather than empty calories, such as sugar, corn syrup, starches etc. See some of the other answers on weight loss in askville.
