11 Sep 2017 --- Despite eating the same breakfast, made from the same ingredients, people consumed more calories throughout the day when they believed that one of the breakfasts was less substantial than the other.

It was presented on 6 September at the annual conference of the British Psychological Society’s Division of Health Psychology.
