Eating in the absence of hunger is related to loss-of-control eating, hedonic hunger, and short-term weight gain in normal-weight women

Abstract

Eating beyond physiological need contributes to obesity onset. Measuring this behavior could help identify those at risk for weight gain. This study measured eating in the absence of hunger (EAH) and its relationship with weight change and self-report measures related to appetite and eating behavior.

Participants also completed questionnaires, and their body weights were measured regularly over the next year. Participants consumed a mean 188 calories (±140) during the EAH test. Caloric intake during the EAH test was associated with hedonic hunger (p
