In a paper presented at the European Congress on Obesity last month, researchers concluded that weight gain in the United States over the past 30 years can be attributed almost entirely to calorie intake, as opposed to lack of physical activity. Scientists looked at data from previous large food and activity surveys and concluded that physical activity has changed little in recent decades whereas calorie intake has increased significantly, accounting for virtually all the observed weight gain. A related paper appears in this month’s American Journal of Clinical Nutrition.
