Factors influencing obesity in men and women revealed by brain scans.

Changes in the way peoples’ brains are wired could explain some of the differences in obesity between men and women, new research published Thursday finds. In women with obesity, changes in the brain tended to be centered on regions related to emotions, while in men with obesity, the changes tended to be found in regions that play a role in gut sensations, such as how hungry or full a person feels, the study found. The findings could have implications for personalized treatments for obesity, Gupta said, noting that the research also highlights the feedback loop between the brain and the gut.
