Obese patients after gastric bypass surgery have lower brain-hedonic responses to food than after gastric banding

Conclusions
The identification of these differences in food hedonic responses as a result of altered gut anatomy/physiology provides a novel explanation for the more favourable long-term weight loss seen after RYGB than after BAND surgery, highlighting the importance of the gut–brain axis in the control of reward-based eating behaviour.
