“Women and men of average height need to gain or lose about three and a half and four kilograms, or about eight and nine pounds, respectively, for anyone to see it in their face,” said Nicholas Rule, associate professor in the Faculty of Arts & Science and Canada Research Chair in Social Perception and Cognition.
