All right. James Levine, welcome to the show.
Dr. James Levine: Thank you so much for having me, Brett. So you have spent your career researching obesity, particularly how our physical activity levels can contribute to how trim we are or how fat we are. When it comes to the way our body burns or uses calories, you’ve broke it down in your work, and there’s basically three ways our bodies burn calories. What are those three ways our body uses calories?
Yeah, the three basic ways we burn calories are there is the basal metabolism. Basal metabolism accounts for about 60% of the total. The bigger you are, the bigger your basal metabolism, or more specifically, the greater your lean body mass, the greater your basal metabolism. Now what’s important is, yes, it’s actually the majority burn, but you can’t change it. So moving on, the next one is the thermic effect of food. It accounts for about 11% of the total. Now, those are the calories you expend when you convert your meal into intermediary metabolites like glycogen and glucose.
