A study of the diets of 22,000 people over five years found that all of them gained weight, but those who switched to a vegetarian diet gained the least amount.
Over Four Pounds in Five Years
On average, study participants gained just under 4.5 pounds over the course of the study. None of the participants were overweight. In addition to diet, exercise proved to be a key factor in weight control.
Part of a Larger Study
The research is part of a much larger study of 500,000 people in 10 countries, intended to examine how diet is linked to cancer.
