The same reward circuitry that responds to addictive substances responds to hyperpalatable food, and brain imaging finds the parallel with large effect sizes — heightened anticipatory reward alongside reduced inhibitory control. But the strongest evidence for tolerance, withdrawal, and escalation comes from rat studies whose own authors concluded only that this may translate to some human conditions, and the food-addiction model remains scientifically debated: human imaging results largely conflict, no addictive agent in food has been identified, and binge-eating treatments do not match the model’s predictions. None of that makes the experience less real. It reframes it — a strong reward system doing its job in an environment built to exploit it, rather than an addiction you have contracted — which is still enough to explain why “just don’t eat it” fails.
This companion covers the shared circuitry, how it works, what the evidence does and doesn’t show, and the implications for change. (7 min read)
