Biography:

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.

Funded Research:

Effect of varying the fat composition of a carbohydrate restricted diet

Effect of a novel whey protein on markers of vascular function

Physiogenomic method for predicting responses to carbohydrate restricted and low fat diets

Safety and efficacy of NBTY products as part of a carbohydrate restricted diet with and without resistance exercise

Potential of eggs in enhancing the cardiprotective effects of carbohydrate restricted diets in weight loss interventions

Hyperglycemia-mediated alterations in vascular endothelium function and redox sensitive parameters

Investigation of whey protein supplementation for physiologic enhancement to resistance training and dietary regimes in young adults
