Therefore, we tested whether the amount of money paid for a meal influenced the portion size effect at a lunch served in a controlled restaurant-style setting. In a crossover design, 79 adults (55 women; 24 men) came to the lab once a week for 4 weeks to eat a main dish of pasta with side dishes. Across weeks, the meal was varied in two factors: portion size of the main dish (400 g or 600 g) and cost of the meal (US$8 or $16). At discharge subjects completed questionnaires that assessed behaviors thought to influence the response to portion size and cost. Results showed that the portion size of the main dish had a significant effect on meal intake (P < 0.0001). The weight of food consumed at the meal increased by 18 ± 2% (mean ± SEM 83 ± 11 g) and energy intake increased by 20 ± 2% (133 ± 16 kcal) when the larger portion was served. These effects of portion size did not differ across the two levels of cost (both interactions P > 0.37) nor did meal cost have significant effects on meal intake (both P > 0.24). Subject scores for satiety responsiveness did, however, influence the effect of portion size on food intake (P = 0.0007). Serving larger portions led to increased intake in subjects with lower satiety responsiveness scores (P < 0.0001), but did not affect intake in those with higher scores. In summary, the effect of portion size on intake in a restaurant-style setting was not influenced by meal cost but was attenuated in individuals higher in satiety responsiveness.","is_dataset_classified":null,"base_score":2.995732273553991,"endowment":2.995732273553991,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"29772292","pmcid":"PMC12831231","openalex_id":"https://openalex.org/W2804822837","authors":[],"funders":[{"funder_name":"National Institutes of Health","grant_id":"R01-DK059853","title":null},{"funder_name":"USDA","grant_id":"2011-67001-30117","title":null},{"funder_name":"NIDDK NIH HHS","grant_id":"R01 DK059853","title":null}],"total_grants":3,"fwci":2.8955,"citation_percentile":0.90130126,"influential_citations":0,"citation_trend":[{"year":2018,"count":1},{"year":2019,"count":4},{"year":2020,"count":4},{"year":2021,"count":2},{"year":2022,"count":2},{"year":2023,"count":3},{"year":2024,"count":1},{"year":2025,"count":2}],"oa_status":"green","license":"cc-by-nc-nd","oa_locations":[{"url":"https://scholarsphere.psu.edu/resources/083d1f89-0bcd-4a49-81c1-15151c898454","host_type":"repository"},{"url":"https://scholarsphere.psu.edu/resources/083d1f89-0bcd-4a49-81c1-15151c898454","host_type":"repository"},{"url":"https://api.elsevier.com/content/article/PII:S0195666318300709?httpAccept=text/xml","host_type":"publisher"},{"url":"https://api.elsevier.com/content/article/PII:S0195666318300709?httpAccept=text/plain","host_type":"publisher"},{"url":"https://doi.org/10.1016/j.appet.2018.05.020","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/29772292","host_type":"repository"},{"url":"https://pmc.ncbi.nlm.nih.gov/articles/PMC12831231/","host_type":"repository"}],"fields_of_study":["Eating Disorders and Behaviors","Obesity, Physical Activity, Diet","Consumer Attitudes and Food Labeling","Adult","Consumer Behavior","Costs and Cost Analysis","Cross-Over Studies","Eating","Energy Intake","Female","Humans","Male","Meals","Middle Aged","Portion Size","Satiety Response","Surveys and Questionnaires"],"mesh_terms":["Adult","Energy Intake","Consumer Behavior","Costs and Cost Analysis","Eating","Female","Humans","Male","Middle Aged","Surveys and Questionnaires","Satiety Response","Cross-Over Studies","Meals","Portion Size"],"keywords":["Meal","Portion size","Animal science","Food intake","Crossover study","Affect (linguistics)","Medicine","Food science","Biology","Psychology","Internal medicine","Communication","Energy intake","Satiety Responsiveness","Meal Cost"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Zero hunger"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-06T17:42:59.876189Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
