BACKGROUND: Eating while distracted [e.g., television (TV) watching, phone use] is believed to increase food intake. A previous small meta-analysis of experimental studies (published in American Journal of Clinical Nutrition) supported this. Many studies have since been published, but there has been no updated analysis. OBJECTIVES: This study aimed to conduct an updated systematic review and meta-analysis to examine the effect of distraction on concurrent and later energy intake. METHODS: Eligible articles (searching up to December 2024) were identified from: a previously conducted meta-analysis which included studies up until 2012; database searches from 2012 to 2024 (PsycINFO, Medline, and PubMed); and both forward and backward citation searching. We followed PRISMA guidelines and conducted generic variance inverse meta-analyses with intake as the outcome variable for both concurrent and later energy intake. RESULTS: A total of 50 eligible studies were included (40 measuring concurrent intake, 10 measuring later intake). Random effects meta-analyses revealed that the overall effect of distraction on concurrent energy intake was nonsignificant [standardized mean difference (SMD) = 0.123, 95% confidence interval (CI): <-0.01, 0.25; P = 0.051]. Moderator analyses revealed that type of distractor moderated the effect of distraction on eating, with passive distractor tasks (e.g., TV watching) resulting in greater energy intake when distracted [SMD = 0.272 (95% CI: 0.128, 0.417)], whereas physically demanding distractors [SMD = -0.139 (95% CI: -0.334, 0.057)] and cognitively demanding distractors [SMD = 0.202 (95% CI: -0.028, 0.432)] did not. The effect of distraction on later energy intake was statistically significant, such that eating while distracted led to greater intake at a subsequent eating episode [SMD = 0.419 (95% CI: 0.195, 0.642)]. CONCLUSIONS: Distracted eating increases later energy intake; however, the effect of distracted eating on concurrent energy intake is less consistent, and only relatively passive distractors may increase energy intake. Collectively, these findings suggest that distraction is a potential contributor to overeating. This systematic review and meta-analysis was registered at PROSPERO as CRD42024518245.
