Your Body Can Either Grow or Repair — Not Both, Here’s Why (Ft Renee Fitton)

Why is it that we chase longevity like it’s a number, yet ignore the daily behaviors that are aging us from the inside out?

Most of us think longevity is about adding years. But what if it’s really about removing what no longer serves you at the cellular level and at the identity level?

Renee Fitton — registered dietitian, longevity specialist, and one of the leading voices in fasting-mimicking science (VP at Prolon) — breaks down the biology of renewal… and the psychology that quietly shapes our habits.
