Their weight would be pretty much the same, and their bodies would not suffer the wear and tear from losing weight and gaining it all back. People on diets typically lose 5 to 10 percent of their starting weight in the first six months, the researchers found.

Mann said that certain factors biased the diet studies to make them appear more effective than they really were. For one, many participants self-reported their weight by phone or mail rather than having their weight measured on a scale by an impartial source. Also, the studies have very low follow-up rates — eight of the studies had follow-up rates lower than 50 percent, and those who responded may not have been representative of the entire group, since people who gain back large amounts of weight are generally unlikely to show up for follow-up tests, Mann said.
One study found that both men and women who participated in formal weight-loss programs gained significantly more weight over a two-year period than those who had not participated in a weight-loss program, she said. In several studies, people in control groups who did not diet were not that much worse off — and in many cases were better off — than those who did diet, she said.
