How obesity, diet and exercise influence our metabolism and interact with our genome

Research by kinesiology investigator Dustin Hittel, PhD, has proven that muscle in extremely obese individuals produces large amounts of a protein called myostatin, which normally inhibits muscle growth-suggesting that for Type 2 diabetics, and the very obese, the task of getting healthy may be more difficult than initially thought.
