Negative Emotions Can Fuel Emotional Eating

New research finds that eating and especially overeating in response to negative emotions is a risk factor for binge eating and developing eating disorders such as bulimia.

Eating can serve different functions such as survival, pleasure, comfort, as well as a response to stress. Emotional overeating — eating past the point of feeling full — in response to negative emotions may be dysfunctional.

“Even at a healthy BMI, emotional overeating can be a problem,” said doctoral student Rebekka Schnepper of the University of Salzburg in Austria. Schnepper co-authored the recent study in the journal Frontiers in Behavioral Neuroscience.

The study investigated the extent to which individual eating styles and emotional states predict appetite response to food images.

Researchers compared emotional eaters — people who use food to regulate negative emotions — and restrictive eaters — people who control their eating through diets and calorie restriction. (While a person can be both an emotional and a restrictive eater, the two traits were not highly correlated in this study’s sample.)

Schnepper and her co-authors found that emotional eaters had a stronger appetite response and found food to be more pleasant when experiencing negative emotions compared to when they felt neutral emotions.

Restrictive eaters, on the other hand, appeared more attentive towards food in the negative condition although this did not influence their appetite, and there was no significant change between the negative and neutral emotion conditions.

The findings point towards potential strategies for treating eating disorders.

“When trying to improve eating behavior, a focus on emotion regulation strategies that do not rely on eating as a remedy for negative emotions seems promising,” said Schnepper.

The authors were compelled to investigate the subject because of a lack of consensus in the literature.

“There are different and conflicting theories on which trait eating style best predicts overeating in response to negative emotions. We aimed to clarify which traits predict emotional overeating on various outcome variables,” Schnepper said.

The study was conducted among 80 female students at the University of Salzburg, all of whom were of average body mass index (BMI).

During the lab sessions, experimenters read scripts to the participants in order to induce either a neutral or a negative emotional response. The negative scripts related to recent events from the participant’s personal life during which they experienced challenging emotions, while the neutral scripts related to subjects such as brushing one’s teeth. The participants were then shown images of appetizing food and neutral objects.

Researchers recorded participants’ facial expressions through electromyography, brain reactivity through EEGs (electroencephalography), as well as self-reported data. For example, emotional eaters frowned less when shown images of food after experimenters read the negative script compared to when they read the neutral script, an indication of a stronger appetite response.

The study chose to only test female participants since women are more prone to eating disorders and were available to participate in the subject pool. As such, Schnepper said, “We cannot draw conclusions for men or for long-term eating behavior in daily life.”

Nevertheless, researchers believe the study furthers the understanding of emotional overeating, and the findings may help in the early detection and treatment of eating disorders.
