Why we cite it
A theoretical framework for stress-driven eating: ”We propose a theoretical model of Reward Based Stress Eating.” The authors ”attempt to link animal and human literatures”; the model emphasises cortisol and reward circuitry, and names leptin, insulin and NPY as possible mediators. Opioid release, which both stress and palatable food can stimulate, ”appears to be part of an organisms’ powerful defense mechanism” that attenuates the stress response. The authors advance this inside a proposed model, not as a demonstrated result. They close that the obesity epidemic ”may be exacerbated by” chronic stress, unsuccessful food restriction, ”and their independent and possibly synergistic effects” on the reward value of palatable food.
