Does fast weight loss promote eating disorders in obese women?

Unfortunately, this opportunity is currently unavailable. Please check back at a later date.

Summary

This project aims to determine whether very low energy diets (VLED) may contribute to the development of disordered eating in obese women.

Supervisor(s)

Associate Professor Amanda Salis

Research Location

Camperdown - Boden Institute of Obesity, Nutrition, Exercise & Eating Disorders

Program Type

Masters/PHD

Synopsis

For many years health professionals have recommended ‘slow and steady' weight loss. Recently however an increasing number of health professionals have begun prescribing severely restrictive VLEDs for the management of excess body weight. VLEDs can induce fast weight losses of approximately 0.5 to 2 kilos per week, which some people find motivating. Moreover, some people report not feeling hungry while on a VLED.

While VLEDs clearly improve metabolic health in people who are obese, little is known about their potential psychological effects. Of concern is the fact that severe energy restriction in lean people is a known contributor to eating disorders such as anorexia nervosa, bulimia nervosa and binge eating disorder. Whether or not the same effects of severe energy restriction also occur in obese people on VLED is currently unknown.

With funding from a project grant from the National Health & Medical Research Council (NHMRC), this project will demonstrate whether or not there are any differences between VLED and a less restrictive weight reducing diet with respect to effects on psychological parameters that are associated with eating disorders. Drawing on cutting-edge psychological and neuropsychological assessments, the results from this study will have important implications for the clinical management of obesity and the prevention of eating disorders.
