Because fructose is a carbohydrate that provides energy (calories), consumption of it will decrease hunger and help to signal satiety.
A comprehensive review by Dolan et al. in 2010 found that fructose consumption did not increase overall food intake. It is unclear if fructose affects hunger and satiety to the same extent as other carbohydrates. In a Moyer and Rodin (1993) study that investigated the potential role of fructose as a hunger suppressant, the investigators found that fructose may be more satiating than other carbohydrates (Moyer & Rodin, 1993). A 2009 review study by Moran found that the results of studies comparing the effect of fructose on satiety to that of other sugars were mixed, with some studies showing differences while others did not.
