A fad diet is a diet that suddenly becomes popular, usually because it promises people that they will lose a lot of weight overnight. Although dieters may really show weight loss from a fad diet, they will almost certainly get back the weight if their usual eating habits (习惯) remain unchanged. Moreover, fad diets continuously call for special products of questionable value or for “health foods” that may cost twice as much as supermarket(超市) foods. Worse yet, certain fad diets don't include nutrients(营养)good for health. People have been known to become very ill as a result of following medically unhealthy diets.
The worse fact of fad diets, though, is that they keep people who are over-weight or sick from receiving the medical care that they truly need.
