Biography

Christos Katsanos is an exercise physiologist who studies metabolic responses in obese individuals. He is interested in how insulin resistance, which is a common observation in obesity, may contribute to metabolic abnormalities that are specific to skeletal muscle protein and fat metabolism. He is particularly interested in how muscle protein and fat metabolic responses in obese individuals can be favorably altered by exercise and dietary interventions.
