STRESS & APPETITE

from journal PLOS One

Stress increases our appetite. That is the message from Johns Hopkins Researchers writing in the journal PLOS One. Participants in the study were given functional MRI brain scans, during which they were given food words and asked to imagine how each food looked, smelled and tasted. After the second MRI, the participants were given a combined social and physiological stress test. Researchers found stress affects the brain’s responses to food in both lean and obese participants, but obese people had greater response to food words, especially high-calorie foods. Conversely, lean individuals who reported higher stress following the test showed lower activity in a key brain region for cognitive control.
