Deseret News special Don't waste your time envying people who can eat and eat and never gain weight. According to a recent study, such people probably don't even exist, says the Nutri/-System Health & Fitness Information Bureau.

When researchers from the USDA Human Nutrition Research Center on Aging at Tufts University asked a group of healthy, average-weight men to consume 1,000 extra calories every day for three weeks, they found that all the men gained weight. Once the men stopped overeating, their weight rapidly returned to normal."Nobody has a magical way to stop excess calories from turning into fat," explained Peter D. Wood, professor of medicine at Stanford University's School of Medicine and a member of of the Nutri/System National Health Sciences Advisory Board. "The unavoidable fact is, if you don't burn up extra calories through increased physical activity, you gain weight."
