Main article: Dieting A desire to lose weight is a common motivation to change dietary habits, as is a desire to maintain an existing weight. Many weight loss diets are considered by some to entail varying degrees of health risk, and some are not widely considered to be effective. This is especially true of "crash" or "fad" diets. Many of the diets listed below could fall into more than one subcategory. Where this is the case, it is noted in that diet's entry.
