Decreased Emotional Perception in Obesity

Eur Eat Disord Rev. 2016 Jul;24(4):341-6. doi: 10.1002/erv.2444. Epub 2016 Apr 4.

Abstract

Background: There is hardly any empirical evidence on emotion processing by controlled studies in obesity.

Material and methods: Participants rated their emotions in response to visual emotional stimuli from the International Affective Picture System. Study 1 compared obese women with normal-weight controls and women with eating disorders. Study 2 compared obese men with normal-weight controls.

Results: Obese women had reduced emotional intensity scores for all basic emotions and the mixed emotion sadness-fear. Obese men had reduced scores for all emotions except happiness and disgust; anger showed a trend towards significance. The results were mainly based on ratings from non-depressed obese individuals.

Discussion: Obese men and women scored significantly lower on most basic and mixed emotions. Non-depressed obese subjects seem particularly affected. These new findings must be validated by further study, and longitudinal evaluation after weight loss, e.g. by bariatric surgery, will be of interest.
