Appetite Regulation
Matching food intake to the body's energy needs. A well-regulated appetite is meant to be self-correcting — nudging you toward a surplus when you're underweight and a deficit when you carry excess fat. But cheap, energy-dense, hyperpalatable food easily overrides those satiety signals, driving chronic overeating and weight gain, so for many people the practical goal is to suppress appetite — while the underweight, ill, or undernourished need to stimulate it. For that reason the substances and behaviors below aren't scored good or bad: ↑ marks things that raise appetite and ↓ things that lower it, and which one helps depends on your body and your goal.
(↑) raises appetite · (↓) lowers appetite — neither is inherently good; it depends on whether you need to gain or lose.
