How the Best Athletes "Burn" Fat for Fuel - Endurance Metabolism | Nick Sterling, M.D., Ph.D. #2

Nick Sterling, MD, PhD

In this episode, we discuss fat through the lens of performance and survival, and what happens when we push our energy systems to their limits. We also talk about how our bodies make adaptations via exercise to improve our ability to "burn" fat for fuel, and how our bodies conserve fuel during times of negative energy balance. Lastly, we preview the role of fat as an endocrine organ and the importance of its communication with the brain, as well as the critical role of exercise capacity for our future health.
