VAS, visual analogue scale.
Values presented are means and standard deviations, unless otherwise stated. Baseline hunger is on a 0–100 mm scale (anchors: 1=‘not at all hungry’, 100=‘extremely hungry’). Dietary restraint, disinhibition and emotional eating are represented by a score from 1 to 4, with higher scores denoting higher dietary restraint, dietary disinhibition and emotional eating. Statistical difference between small and large bowl conditions is compared using a t test, except for gender (χ 2 test).
