The Best Weight-Loss Supplements
Alpha Lipoic Acid
What it is: A fatty acid found in red meats and organ meats.
How it works: This antioxidant reduces inflammation and can help you lose weight. In a 2011 study published in The American Journal of Medicine, obese people who were told to reduce their food intake prior to the study by 600 calories a day and who took 1,800 milligrams of alpha lipoic acid daily for 20 weeks lost significantly more weight—up to 5 percent of their total body weight—than did a placebo group.
Good to know: While it’s generally best to get nutrients from foods, supplements win out in this case, since the foods most laden with alpha lipoic acid—red and organ meats—are also packed with saturated fat and cholesterol. Take anywhere from 1,200 to 1,800 milligrams a day.
