Beetroot, Blood Flow, and Freaks of Physiology with Dr. Eric Trexler

Описание: In this episode of the Flex Diet Podcast, I’m joined by my good friend Dr. Eric Trexler, exercise scientist, educator, and Director of Education at Stronger by Science, for a wide-ranging, no-BS conversation on what physiology actually looks like in the real world.

We dig into beetroot juice, nitric oxide, and “pump” supplements, why the blood-flow story is usually oversold, and why neuromuscular function and calcium handling may matter far more than chasing a swollen muscle. We also talk about why most supplement mechanisms sound great on paper… and quietly fall apart once you look at healthy humans who already function pretty well.

From there, the conversation expands into human variability, elite athletic outliers, and why normal distributions actually guarantee that “freaks” exist — whether people are comfortable admitting it or not. We also unpack NEAT, energy expenditure, and why exercise doesn’t scale linearly for fat loss, including how the body aggressively manages its energy budget when stress or activity gets too high.

If you care about performance, body composition, or just understanding how the human system really works, this episode will recalibrate a lot of assumptions.
