The document warns about empty weight loss promises and dubious diets and supplements being promoted in 2012. It highlights two such programs - the HCG diet, which uses injections of a pregnancy hormone along with severe calorie restriction but has no proven long-term effectiveness or safety, and Calotren, a supplement that claims to burn fat but actually causes weight loss through calorie restriction and its laxative property of aloe vera. The document advises consumers to be skeptical of miracle cures and do their research before trying questionable diets or supplements.
