A physician and clinical researcher, Holly has extensive experience in weight loss using medications and behavioral, dietary, physical activity and surgical treatments.

Holly is co-author of State of Slim, revealing how Coloradans get and stay slender. As medical director of Extreme Weight Loss, she uses these principles to guide cast-member journeys.

Her research interests include resting and total energy expenditure, fat oxidation and activity levels in weight-reduced populations. She studies the effect of diet on long-term success, as well as weight loss with Atkins’ vs. low fat-high carb diets and diet composition, exercise patterns and breakfast consumption in the National Weight Control Registry.
