Studies of appetitive behavior in humans after RYGB have produced ambiguous results. It therefore remains unclear whether there are fundamental shifts in the palatability of high-fat and sugary foods after RYGB or simply a decrease in the appetitive drive to ingest them. Moreover, learning processes may play a role as changes in diet selection progress with time in rats after RYGB. However, direct measures of an altered food selection in humans after RYGB are rare and both the durability of the phenomenon as well as the role of experience for changes in food selection remain elusive.
