Scientists now say that if your stress level is too high, it could lead you to overeat. Managing stress, therefore could be an important part in maintaining a healthy weight and healthy body.

Researchers in the Hotchkiss Brain Institute (HBI) at the University of Calgary’s Faculty of Medicine have uncovered a mechanism by which stress increases food drive in rats. This new discovery, published online this week in the journal Neuron, could provide important insight into why stress is thought to be one of the underlying contributors to obesity.

Normally, the brain produces neurotransmitters (chemicals responsible for how cells communicate in the brain) called endocannabinoids that send signals to control appetite. In this study, the researchers found that when food is not present, a stress response occurs that temporarily causes a functional re-wiring in the brain. This re-wiring may impair the endocannabinoids’ ability to regulate food intake and could contribute to enhanced food drive.
