The hosts reveal why reaching for NAD+ supplements misses the point—it's like adding more battery packs to a device you never unplug—and instead provide actionable strategies to restore natural battery cycling through consistent fasting windows, protein-based meals, post-meal movement, and protected sleep. They explain how continuous glucose monitors show you the real-time movie of your metabolic battery's charge-discharge cycle, not just the final score like A1C tests, helping you understand why certain food choices create the wired-and-tired, crashing-after-meals pattern that sabotages your fasting efforts and keeps you trapped in a cycle of cravings and inconsistent results.
