In this episode, we dive into the world of metabolic age — what it is, how it's measured, and why it can be such a useful marker of health, especially once you hit your forties. Frank shares his own recent result (spoiler: he scored a metabolic age of 25 and hasn't stopped telling people about it), and we unpack what that number really means for your long-term fitness, health, and motivation. Whether your metabolic age is younger, older, or bang on your years, this conversation will help you understand what's behind the number and how to use it to your advantage.
