Negative Emotions can Cause Stronger Appetite Responses in Emotional Eaters

People who use food to regulate negative emotions found the food to be more pleasant when experiencing adverse emotions, reports a new study.

Emotional eaters had a stronger appetite response, and found the food to be more pleasant when experiencing negative emotions compared to when they felt neutral emotions, reports a new study. The findings of the study are published in the journal Frontiers in Behavioral Neuroscience.//

Turning to a tub of ice cream after a break-up may be a cliché, but there's some truth to eating in response to negative emotions. Eating serves many functions - survival, pleasure, comfort, as well as a response to stress. However, emotional overeating - eating past the point of feeling full in response to negative emotions, is a risk factor for binge eating and developing eating disorders such as bulimia.

All You Need to Know about Eating Disorders
Eating disorders involve extreme attitudes and behaviors towards food and weight. It has the highest suicidal mortality rate than other mental illnesses.

‘Emotional eating is a risk factor for binge eating and bulimia, which may help in the early detection and treatment of eating disorders. ’

"Even at a healthy BMI, emotional overeating can be a problem," says Rebekka Schnepper of the University of Salzburg in Austria, who co-authored.

The study investigated the extent to which individual eating styles and emotional states predict appetite response to food images, by comparing 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 the food to be more pleasant when experiencing negative emotions compared to when they felt neutral emotions.

When a person overeats, he is unable to control his hunger pangs, while during an emotional/binge eating session, he is incapable of controlling his 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," says Schnepper.

Chronic Dieting - Is it an Eating Disorder?
Chronic dieting is associated with eating disorders that mainly include unhealthy eating practices such as severe calorie restriction in diet of men or women who on a regular basis follow fad diets mainly to reduce weight.

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," says Schnepper.

They conducted the study 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.

Sleep Eating Disorders Causes Symptoms Diagnosis Treatment
Sleep-related eating disorders are abnormal eating behaviors that occur during night. Sleep related eating disorder is a part of parasomnias.

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 but, given the limited subject pool as well as the controlled conditions, Schnepper says that "We cannot draw conclusions for men or for long-term eating behavior in daily life." Nevertheless, the study furthers our understanding of emotional overeating, and the findings may help in the early detection and treatment of eating disorders.
