Rolls BJ, Morris EL, Roe LS. Portion size of food affects energy intake in normal-weight and overweight men and women. Am J Clin Nutr. 2002 Dec;76(6):1207-1213. doi:10.1093/ajcn/76.6.1207
Why we cite it
Reports that the response to portion size ”was not influenced by who determined the amount of food on the plate or by subject characteristics such as sex, body mass index, or scores for dietary restraint or disinhibition”, in 51 men and women, portion varied within subjects. *The authors themselves conclude ”regardless of serving method and subject characteristics”. That is a failure to detect moderation, not a demonstration that none exists. It uses the same macaroni-and-cheese paradigm as Rolls and colleagues’ 2000 study in children, with adults. The authors: ”Portion size is a modifiable determinant of energy intake”*.
