Spontaneous meal patterns of humans: influence of the presence of other people

de Castro, J M, de Castro, E S·1989·The American Journal of Clinical Nutrition

Abstract

Social influences on eating were investigated by paying 63 adult humans to maintain 7-d diaries of everything they ingested, time, subjective hunger, and number of people present. Meals eaten with others contained more carbohydrate, fat, protein, and total calories; had smaller deprivation ratios; and had larger satiety ratios than meals eaten alone. The number of people present was positively correlated with meal size even when meals eaten alone were excluded. Adding the number of people present as a factor in a multiple-regression prediction of meal size more than doubled the variance accounted for, without altering the influence of other predictors, suggesting that social factors are associated independently with an increase in meal size. Meal size was positively correlated with the postmeal interval for meals eaten alone but not for meals eaten with other people. This suggests that social factors increase amounts eaten and disrupt postprandial regulation.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
