Systematic review and meta-analysis published in the American Journal of Clinical Nutrition that pooled 24 studies of how attention and memory affect eating (exactly how much removed 2026-09-19). The most striking finding isn’t the immediate effect of distraction (SMD 0.39, moderate) but the delayed effect: distraction increased later intake to a greater extent than immediate intake — SMD 0.76 (95% CI 0.45, 1.07) against SMD 0.39 (0.25, 0.53) — the authors’ proposed reading being that the meal was not properly encoded into memory and so does not suppress later appetite. The review also showed that actively recalling what you ate reduces later intake (SMD -0.40), and that removing visual evidence of eating (pistachio shells, cleared plates) increases consumption (SMD 0.48). For the project, this is the evidence base for attentive eating. The authors offer memory as the likely route, hedged: impaired memory ”suggests that memory representation may be the underlying mechanism”. They also say no attentive-eating intervention had yet been tested. (Corrected 2026-09-19. This sentence said ”the mechanism isn’t mystical mindfulness but concrete memory encoding — when you pay attention to eating, your brain records the meal, and that record suppresses subsequent hunger”. That states the proposed mechanism as settled, and the memory result carries the abstract’s own caveat about disinhibited eating.) This connects to cpi04 (Zlatevska 2014): attentive eating is identified there as a moderator that weakens the portion size effect.
