Summary

This study tracks 420 people to see how bariatric surgery affects drinking behavior using a special device called a drinkometer. It measures things like sip size and speed, and looks at how gut hormones and sex differences play a role. The goal is to better understand why surgery helps with weight loss, beyond what people report about their eating habits.
