Research Interests

Dr. Kratz’s research focuses on the relationship between diet, obesity, and chronic diseases such as type 2 diabetes, cardiovascular disease, and cancers associated with obesity. Current projects are either controlled dietary intervention studies in humans to better understand how diet composition affects glucose homeostasis and liver fat, or clinical studies that aim to understand the biological mechanisms linking diet, obesity and chronic disease. All of these studies focus on chronic low-grade systemic inflammation and adipose tissue inflammation, a major factor in the etiology of many chronic diseases.

Clinical Expertise 
Dr. Kratz has more than 15 years of experience conducting clinical studies in a variety of human populations.
