Title: A Double-blind, Randomized Trial of the Efficacy of Replacing Sugary Drinks by Low-sugar Alternatives on Body Weight and Fat Mass in School Children
Brief Summary: Obesity results from an imbalance between energy intake and energy expenditure. There is much speculation about foods that are particularly fattening, and sugary drinks are seen as major culprits. It is hypothesized that a high intake of calories from sugary drinks would not be compensated for by reduced food intake at subsequent meals. As a result, body weight would increase. In this double-blind, long term, randomized controlled trial the effect of replacing sugar-containing beverages by low-sugar alternatives on body weight and fat mass in children will be investigated.
