Why we cite it
Landmark PNAS paper providing the biological mechanism explaining why people eat comfort food when stressed — and why it actually works in the short term. Demonstrates that chronically elevated cortisol drives comfort food consumption through three congruent pathways, and that the resulting abdominal fat sends feedback signals that genuinely suppress the stress response. Published in one of the world's highest-impact journals, this paper reframes stress eating from a willpower failure to a biological self-medication strategy with short-term benefits and long-term metabolic costs.
