Comfort food leads to more weight gain during stress
A combination of chronic stress and high-calorie diets raised insulin levels tenfold in the amygdala of mice.

The desensitized neurons boosted NPY levels, which promoted eating and reduced the normal homeostasis response to burn calories. The findings may shed light on why some indulge in high-calorie foods when stressed, and why this may lead to obesity.... Read More...
