Question

How do neurotransmitters work in relation to stress and comfort food

Answer 1

A group of hormones that are released when we are stressed are called glucocorticoids.  These glucocorticoids remain in the blood for a significant time after the stressor is removed.  Put a person under chronic stress and they will have constantly high amounts of glucocorticoids in their blood.

The glucocorticoids initiate the release of corticotrophin-releasing factor (CRF) which is a key player in our stress response.  They also increase our cravings for sugary foods and they also act directly on increasing abdominal fat storage
