![Page 6: Cortisol,Hunger, and Desire to Binge Eat Following a Cold Stress Test in Obese Women with Binge Eating Disorder Gluck ME, Geliebter A, Hung J, and Yahav.](https://reader035.fdocuments.net/reader035/viewer/2022081520/5697bfd61a28abf838cade65/html5/thumbnails/6.jpg)
Hypothesis
Obese women with BED compared with non-BED
1. Increase CORT after CPT
2. More hungry and desire to binge eat after CPT
3. Less CORT suppression after DST
