Adherence

Exposure to environmental food cues (visual, olfactory, marketing) can trigger conditioned food intake and override homeostatic satiety signals, leading to overconsumption even when metabolically replete.

Your environment drives your eating more than your hunger. If you are exposed to constant food cues (ads, availability), your brain will trigger eating even when full. To manage this, you must minimize exposure to these cues (e.g., unsubscribe from food marketing, keep healthy foods visible and junk food hidden) because willpower alone is insufficient against conditioned responses.

Conditioned stimuli can induce food intake in satiated rats... stimuli from the environment clearly have the capacity to temporarily overwhelm homeostatic regulation.

Why this rating

Strong animal model evidence (Weingarten, Petrovich) and human observational data, though long-term human causal links are noted as less direct.
