Holly Wyatt, M.D.,Associate Professor of Medicine
University of Colorado
Dr. Holly R. Wyatt is a physician and clinical researcher at The Center for Human Nutrition, University of Colorado School of Medicine, in Denver, Colorado. Research interests include studies aimed at understanding whether energy metabolism is altered in obese individuals and in individuals who are successfully maintaining weight loss (reduced-obese). Her research interests also include measuring resting energy expenditure, fat oxidation, total energy expenditure and activity levels in the National Weight Control Registry's (NWCR) long-term reduced population. Dr Wyatt also studies how diet composition affects long-term success in weight loss maintenance. She has studied subjects who are losing weight with...

Elizabeth J. Parks PhD, Professor in the Department of Nutrition and Exercise Physiology
School of Medicine at the University Missouri-Columbia
Dr. Parks lectures on the regulation of body weight and effects of dietary macronutrients on blood lipid levels and conducts research on metabolism. Through studies of mice and humans, she focuses on understanding liver function and how low-fat diets, alcohol use, and diabetes, obesity and heart disease impact it. Her lab provided the first definitive evidence on the factors that contribute to fatty liver in obese humans. Her current research is investigating how the brain, intestine and liver may communicate to maintain energy balance and how the dysregulation of fat metabolism in obesity leads to body fat gain.
