Summary

The objective of this study is to test and determine whether a high protein diet is efficacious, safe and beneficial to curtail food intake and body weight in obese adult human patients and to establish whether neurohormonal mechanisms of a high protein diet induce an early signal of fullness or satiety in a relevant experimental model, focusing on activation of gastric vagal afferents.
