Calories sucrées liquides et satiété : existe-t-il une différence d'effet sur le bilan énergétique ?

Sweetened beverages are said to be responsible for the global obesity epidemic. The consumption of sugar calories in beverages, it is argued, fails to promote satiety, partly because humans lack physiologic mechanisms to process carbohydrate calories in liquid form. As a result, compensation for energy from beverages is said to be imprecise and incomplete, if not lacking altogether. However, the notion that liquids have no impact on satiety mechanisms has little experimental support. Studies have shown that liquid beverages and solid cookies had similar satiety profiles; in other studies, drinkable yogurts and liquid formula diets promoted satiety quite effectively. In laboratory studies, the degree of energy compensation following beverage ingestion was influenced by subject characteristics, beverage volume, and the time lag between the beverage and the next meal. Such factors had a greater impact on hunger, satiety, and later energy intakes then whether the stimulus preload was liquid or solid. On the balance, there was no evidence that liquids lacked satiating power as compared to solid foods.
