Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The objective is to investigate neuro-anatomical correlates of the regulation of energy intake by means of functional MRI. Administration of glucose as well as fructose is followed by functional brain MRI, and findings are correlated with serum glucagon-like peptide 1 (GLP-1) levels as an endogenous satiety signal in obese humans.
