Xylitol has been shown to slow stomach emptying, and thus to help promote a feeling of fullness with less food intake. In one study, those given 25 grams of xylitol at mealtime needed only 690 calories before they felt full. Those who did not use xylitol consumed 920 calories in order to achieve satiety. A preload of glucose, fructose, or sucrose failed to suppress food intake.6 Xylitol, therefore, shows great promise as a natural way to decrease food intake, and thereby help promote weight loss.
