Will you lose weight and keep it off if you diet? No, probably not, UCLA researchers report in the April issue of American Psychologist, the journal of the American Psychological Association.
“You can initially lose 5 to 10 percent of your weight on any number of diets, but then the weight comes back,” said Traci Mann, UCLA associate professor of psychology and lead author of the study. “We found that the majority of people regained all the weight, plus more. Sustained weight loss was found only in a small minority of participants, while complete weight regain was found in the majority. Diets do not lead to sustained weight loss or health benefits for the majority of people.”
