Portion‐size preference as a function of individuals' body mass index
OBJECTIVE: Large portions of food are often blamed for rising rates of obesity. We tested the possibility that people who are heavier may tend to select or prefer larger portions than do people who are lighter. METHODS: Participants (total N = 798) were asked to choose between a small and larger por...

description | OBJECTIVE: Large portions of food are often blamed for rising rates of obesity. We tested the possibility that people who are heavier may tend to select or prefer larger portions than do people who are lighter. METHODS: Participants (total N = 798) were asked to choose between a small and larger portion of pasta for a hypothetical meal (Studies 1, 2 and 4), to indicate their ideal portion from a range of portion‐size options (Study 2), or to select their preferred portion size from each of 28 portion pairs (Study 3). RESULTS: Across all studies, there were no significant differences between heavier and lighter participants in their portion‐size selection (effect sizes ranged from d = −0.06 to 0.33). The pattern was the same regardless of whether we grouped participants as having a body mass index (BMI) <25 vs. ≥25, as having a BMI of <30 vs. ≥30, or treated BMI as a continuous predictor. CONCLUSIONS: Given the lack of association between BMI and portion‐size preference, we suggest that factors other than portion size, such as differences in meal frequency, food type, plate clearing or compensation at subsequent meals, may need to be considered in order to explain the increasing prevalence of obesity. |
