Ep 72 - Hydration (Beyond Water)

September 9, 2026 · 1 h 9 min

Show notes

Trexler and Lauren open with Lauren's return after a mystery 18-hour illness and her travels, followed by a callback to their running guilt-tipping saga — this time being asked to tip at a Canadian grocery-store self-checkout — plus some beverage talk and listener feedback. From there they get into the week's science.

The main thread is hydration beyond plain water: an article on water-rich foods and whether you really need to chase a giant-water-bottle hydration goal, and how much fluid we get from food and other sources. They then look at a New York Post story on Eight Sleep's mattress that claims to track your "biological aging" via in-bed sensors, and debate whether it offers anything over a ring or watch, the limits of sleep-tracking wearables, and the health-tech habit of re-solving already-solved problems. Dr. Drew's endorsement of a C15 (pentadecanoic acid) supplement gets an extended breakdown of the marketing claims and how you'd actually design a study to test them. The episode closes on a listener question about fasted training, where they separate fasted training from low energy availability and discuss the topic through an evolutionary lens before wrapping up.
