Food intake has a larger impact on weight loss than exercise, according to a new study in the International Journal of Obesity. A review of school-based interventions found that weight loss could be achieved by diet changes alone, while exercise without diet changes was not effective. Researchers explain it is difficult to “out-exercise” dietary intake. For example, a one-hour bicycle ride burns 240 calories and, in comparison, one small order of French fries—which are consumed in much less than an hour—contains nearly the same number of calories.
