But Dr. Andrew Koutnik argues the science is more complicated. In this episode, Mike Haney talks with Dr. Koutnik about how the body fuels exercise, why muscle glycogen may not explain “hitting the wall” as neatly as many people think, and why blood glucose, brain energy, insulin, and metabolic flexibility may matter more than conventional sports nutrition advice suggests. They discuss whether athletes really need 60, 90, or even 120 grams of carbs per hour, why some athletes may perform well on far less, and how to think about fueling as an individual experiment rather than a universal rule. Because apparently even “eat sugar while running” was too simple for human physiology to leave alone.
