Dieting is unlikely to lead to long-term weight loss and may put a person's health at risk, a study says.
US researchers found people typically lose between 5% and 10% of their weight during the first six months of a diet.
But the review of 31 previous studies, by the University of California, said up to two-thirds put more weight on than they had lost within five years.
Repeatedly losing and gaining weight is linked to heart disease and stroke, the American Psychologist journal reported.
Lead researcher Traci Mann said: "We found that the majority of people regained all the weight, plus more.
"Diets do not lead to sustained weight loss or health benefits for the majority of people.
"We concluded most of them would have been better off not going on the diet at all.
"Their weight would have been pretty much the same, and their bodies would not suffer the wear and tear of losing weight and gaining it all back."
Professor Mann said in her opinion eating in moderation was a good idea for everybody as was regular exercise.
