Energy Metabolism

 

Mission
The mission of the EMET lab is to explore determinants of energy regulation throughout adult life and contribute to resolving the national obesity epidemic. Studies are conducted on both nutrition (determinants of energy intake and expenditure) and eating behavior, and interventions are being created to expand options for control of energy balance at the individual and group level.

Lab Objectives
1. Test the feasibility and effectiveness of a long-term caloric restriction intervention program for decreasing body fatness, risk factors for chronic disease,and retarding biological aging.

2. Examine the causes of error in the accuracy of reporting energy, macronutrient,and fiber intake from foods.

3. Assess whether a worksite intervention will result in a significant and sustainable reduction in the prevalence of overweight and obese employees and disease risk factors compared to a control group receiving no intervention.

4. Examine the contributions of heritable and environmental factors to eating behaviors and dietary patterns associated with weight gain and body fatness.

5. Assess whether an intervention implemented during pregnancy will result in a significant and sustainable reduction in the prevalence of overweight and obese prior to and subsequent to delivery compared to a control group receiving no intervention.

Lab Members
Susan B. Roberts, Ph.D., Laboratory Director
Senior Scientist and Professor, Nutrition and Psychiatry
Research focus: Dietary, behavioral and cultural determinants of body fatness, and development of behavioral programs for weight loss and prevention of weight regain. This work is currently being conducted both in worksites and military familites in the U.S, and also in different population groups internationally (China, Brazil, India and Italy). In addition, new formulations of foods for prevention and treatment of malnutrition across the lifecycle (U.S. and Guinea Bissau), in particular to reduce susceptibility to obesity and improve cognition.
