jor public health concern with more than 60% of adults in the United States categorized as overweight and more than 30% as obese. 1,2People who become obese have been in a positive energy balance for an extended period.Swinburn et al 3 have argued that this reflects an increase in food intake, but Church et al 4 have presented data showing that reduced occupational activity might account for the positive energy balance.Although a majority of people in the United States are overweight or obese, there is a significant number of people with normal weights who do not become overweight or obese.As obesity develops, a number of metabolic changes occur, which may not completely reverse when weight is lost. 5These differences may reflect differences in the way individuals handle the food they eat each day both during weight gain and weight loss.
