Women with Apple-Shaped Bodies at Greater Risk of Binge Eating

Women with apple-shaped bodies — those who store more fat around the abdomen rather than the hips (pear) — may be at greater risk for binge eating disorders in which they experience a sense of loss of control, according to a new study from Drexel University.

The findings also show that women who store more fat in their midsections report being less satisfied with their bodies, which may contribute to loss-of-control eating.

This study is the first to look at the connections between fat distribution, body image disturbance, and the development of eating disorders.

“Eating disorders that are detected early are much more likely to be successfully treated. Although existing eating disorder risk models comprehensively address psychological factors, we know of very few biologically-based factors that help us predict who may be more likely to develop eating disorder behaviors,” said lead author Laura Berner, Ph.D., who completed the research while pursuing a doctoral degree at Drexel.

“Our preliminary findings reveal that centralized fat distribution may be an important risk factor for the development of eating disturbance, specifically for loss-of-control eating,” said Berner. “This suggests that targeting individuals who store more of their fat in the midsection and adapting psychological interventions to focus specifically on body fat distribution could be beneficial for preventing eating disorders.”

There is growing evidence that experiencing a loss-of-control during eating — feeling driven or compelled to keep eating — is the most significant element of binge-eating episodes regardless of how much food is consumed, say the researchers.

“This sense of loss of control is experienced across a range of eating disorder diagnoses: bulimia nervosa, binge eating disorder, and the binge-eating/purging subtype of anorexia nervosa,” said Berner.

“We wanted to see if a measurable biological characteristic could help predict who goes on to develop this feeling, as research shows that individuals who feel this sense of loss of control over eating but don’t yet have an eating disorder are more likely to develop one.”

For the study, nearly 300 young adult women completed assessments at baseline, six months and 24 months, that looked at height, weight, and total body fat percentage and where it’s distributed. Participants, none of whom met the diagnostic criteria for eating disorders at the start of the study, were assessed for the development of eating disorders through standardized clinical interviews in which experiences of sense of loss of control were self-reported.

The findings showed that participants with greater central fat stores, independent of total body mass and depression levels, were more likely to develop loss-of-control eating and demonstrated steadier increases in loss-of-control eating episode frequency over time. Women with a larger percentage of their body fat stored in the trunk region were also unhappier with their bodies, regardless of their total weight or depression level.

“Our results suggest that centralized fat deposition increased disordered eating risk above and beyond other known risk factors,” said Berner. “The specificity of our findings to centralized fat deposition was also surprising. For example, a one-unit increase in the percentage of body fat stored in the abdominal region was associated with a 53 percent increase in the risk of developing loss-of-control eating over the next two years, whereas total percentage body fat did not predict loss-of-control eating development.”

More research is needed to explain the mechanism behind these findings, but Berner has a few suggestions as to why this might happen.

“It’s possible that this kind of fat distribution is not only psychologically distressing, but biologically influential through, for example, alterations in hunger and satiety signaling,” she said.

“Fat cells release signals to the brain that influence how hungry or satiated we feel. Our study didn’t include hormone assays, so we can’t know for sure, but in theory it’s possible that if a centralized distribution of fat alters the hunger and satiety messages it sends, it could make a person feel out of control while eating.”

The findings may apply to other disordered eating behaviors beyond loss-of-control eating, but more research is needed.

“Body fat distribution hasn’t been studied in disorders characterized by binge-eating behaviors as much as it has in anorexia nervosa,” said Berner. “The participants in our sample didn’t develop eating disorder diagnoses within the two year period that we studied them, but this study suggests that future research should investigate whether individuals with greater central fat stores are more likely to develop bulimia nervosa and binge eating disorder.”

The study is published in the American Journal of Clinical Nutrition.
