Why Some People Can’t Stop Eating: Scientists Discover Unique Brain Circuit Linked to BMI

A newly identified link between two brain areas could influence eating behavior control.
A recent study reveals that weaker connections between brain areas related to smell and behavior motivation are associated with higher BMI, suggesting these pathways influence eating habits and the perception of food reward.

Why can some people easily stop eating when they are full and others can’t, which can lead to obesity?

A Northwestern Medicine study has found one reason may be a newly discovered structural connection between two regions in the brain that appears to be involved in regulating feeding behavior. These regions involve the sense of smell and behavior motivation.
