Exercise & Nutrition
My primary area of research is focused on physiological adaptations to low carbohydrate diets with emphasis on outcomes related to metabolic syndrome, diabetes, and cardiovascular disease. I primarily use prospective diet and/or exercise interventions and use sophisticated cellular techniques to understand changes in adiposity, fatty acid and lipoprotein metabolism, inflammation, vascular function, and endocrine adaptations. Our recent studies have suggested a shift in our understanding of the role of dietary carbohydrate restriction. Long considered primarily a stratagem for weight loss, reduction in dietary carbohydrate is now understood to lead to improvements in metabolic syndrome and other cardiac risk factors, even in the absence of weight loss and frequently even in the presence of higher levels of saturated fat. Another major area of research has been in the general area of sports nutrition including studies evaluating a wide range of dietary supplements on exercise performance and overall health.
