We constructed a mechanistic-ecological model to explain this inconsistency and tested its predictions using population dietary data. The model builds on experimentally established mechanisms to predict that, whereas alcohol will contribute ethanol calories irrespective of diet, its impact on total macronutrient energy intake varies depending on dietary pattern. Alcohol consumption stimulates FGF21, a hormone that increases savory (umami) preference and reduces sweet preference. In minimally processed food environments—where umami flavor is a relatively reliable indicator of protein in foods—umami-seeking should direct consumers toward satiating, high-protein foods, with limited effect on macronutrient energy intake. In contrast, on diets rich in ultra-processed savory foods and/or high-fat unprocessed meats, the correlation between umami flavor characteristics and protein is broken by umami-flavored low-protein foods (protein decoys), so alcohol instead drives dietary protein dilution and, through attenuated protein satiation, increased food and macronutrient energy intake (protein leverage). Mixture analysis paired with nutritional geometry confirmed these predictions in population data, suggesting the model may generalize to ecological contexts. Our results potentially explain why alcohol has variable effects on energy balance across dietary patterns and suggest that it exacerbates the obesogenic effects of ultra-processed diets—a potentially important interaction given their global rise.</p>","PeriodicalId":216,"journal":{"name":"Obesity Reviews","volume":"27 10","pages":""},"PeriodicalIF":7.6,"publicationDate":"2026-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/obr.70138","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147969018","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present review investigated the potential relationship between meal satisfaction-related constructs and childhood obesity, and whether this relation is shaped by individual factors and the external environment. Seventeen eligible studies from 350 records published between 2008 and 2024 were included. No study directly assessed meal satisfaction; instead, proxy measures were used. Food enjoyment emerged as the proxy most consistently associated with BMI, often clustering with higher food responsiveness, lower satiety responsiveness, and emotional overeating. Parental feeding practices, especially pressure to eat, significantly contributed to variation in children's eating behavior and were associated with lower food enjoyment. Overall, meal satisfaction could be a key aspect to consider in childhood obesity prevention programs. However, to date, the available evidence is heterogeneous and predominantly observational.

Evidence was low certainty or very low certainty.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusions</h3>\u0000 \u0000 <p>The average suicide incidence (231 per 100,000 people) in people with obesity who underwent MBS significantly exceeded the 2019 WHO global estimate for the general population (nine per 100,000 people). These findings underscore the need to incorporate structured psychological screening and follow-up into the perioperative management process of MBS, as patient mental health may play a pivotal role in postoperative adherence and long-term outcomes.</p>\u0000 </section>\u0000 </div>","PeriodicalId":216,"journal":{"name":"Obesity Reviews","volume":"27 10","pages":""},"PeriodicalIF":7.6,"publicationDate":"2026-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147466249","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
