The relation of weight suppression and food restriction to eating disorder psychopathology. The role of hedonic hunger in obesity and eating disorders. Obesity and the prevention of weight gain and weight regain. The impact of weight variability on health and future weight gain. Integrating biological and psychological influences on eating and weight regulation.
My research involves studying eating and weight regulation - and eating and weight disorders - from the perspective of clinical psychology, nutritional science, psychobiology, and neuroscience. The following describes five general areas in which my research group has been exploring these domains
- The relationship between dieting, overeating, and weight control
- Obesity and the prevention of weight gain and weight regain
- Eating disorders research
- Integrating biological and psychological perspectives on eating and weight regulation
- Research on the "power of food"
The impact of my research is manifested as follows:
- I developed a comprehensive model accounting for the ways that body weight, and changes in body weight, impact the development and perpetuation of eating disorders
- I developed an obesity intervention to systematically modify the home food environment to promote weight loss
- I created a widely-used measure of “hedonic hunger,” which refers to strong motivations toward palatable foods in the absence of physical hunger
- I established the importance of weight variability, which describes the degree of variation in people’s body weight over time, as a predictor of their susceptibility to future weight gain and difficulty in losing weight
- I consulted with the Renfrew Center for eating disorders over the past 15 years and helped established the first empirically supported treatment approach in a nationwide, community-based eating disorder treatment facility
