This episode I describe the science of fat loss, including how fat is mobilized and oxidized (burned) and how to increase fat burning by leveraging the nervous system. Most people don't realize it, but our neurons connect to our fat and release epinephrine/adrenaline to facilitate fat oxidation. I explain how this can be accomplished with non-exercise movements such as fidgeting to burn thousands of calories of fat a day-- a practice is rarely discussed but very well supported by the science literature. I also discuss an optimal fat loss protocol using cold to create shiver, and how specific types and timing of exercise impact fat loss. I discuss if exercising fasted indeed increases fat oxidation-- it turns out the type and duration of exercise really matters. And I discuss the use of caffeine, GLP1 from Mate or guayusa and emerging new prescription compounds for fat loss. The episode includes a lot of tools, links to cost-free resources and explanation of the science underlying each tool for fat loss.

    Dr. Death

    We’re at our most vulnerable when we go to our doctors. We trust the person at the other end of that scalpel. We trust the hospital. We trust the system. Christopher Duntsch was a neurosurgeon who radiated confidence. He claimed he was the best in Dallas. If you had back pain, and had tried everything else, Dr. Duntsch could give you the spine surgery that would take your pain away. But soon his patients started to experience complications, and the system failed to protect them. Which begs the question: who - or what - is that system meant to protect? From Wondery, the network behind the hit podcast Dirty John, DR. DEATH is a story about a charming surgeon, 33 patients and a spineless system. Reported and hosted by Laura Beil.
