According to a US researchers study, dieting is unlikely to lead to long-term weight loss and may put a person's health at risk."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.' said lead researcher Traci Mann.She added that in her opinion eating in moderation was a good idea for everybody as was regular exercise.
