Fructose not only results in a lower level of satiety, it also stimulates the reward system in the brain to a lesser degree than glucose. This may cause excessive consumption accompanied by effects that are a risk to health.
The research is in PLOS ONE

The MRI image clearly shows how the brain's reward, or limbic, system behaves differently when administered a placebo (top) or one of two types of sugar, glucose (center) and fructose (bottom). Image credit: University of Basel, Department of Biomedicine. #neuroscience #fructose #neuroimaging
