Correlation Between Microstructure of Ingestive Behavior and Body Weight Loss in Patients After Roux-en-Y Gastric Bypass

Marco Bueter·observational·Posted Jun 21, 2021·Updated Aug 18, 2023

In Brief

An observational study evaluating Roux-en-Y Gastric Bypass for Obesity and 6 related conditions. Completed, enrolled 50 participants across 1 site.

Detailed Summary

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.
