Is Your Protein Aging You? What the Longevity Science Gets Wrong
Description
The longevity world has convinced a generation of women that protein is shortening their lives. The science says they've got it backwards and the people hurt most are the ones who need protein most.
In this episode, Dr. Gabrielle Lyon breaks down the protein-and-longevity fear, steelmans the strongest case against protein, then walks through what the evidence shows:
- The RDA (0.8 g/kg) is a deficiency floor, not a target, the intake one camp calls "dangerously high" is what federal guidelines and expert groups now recommend (1.2–1.6 g/kg)
- The IGF-1–cancer link is tiny (a 3–11% risk bump vs. smoking's 1,000–2,000%), and the IGF-1–mortality curve is U-shaped: the lowest levels carry ~40% higher death risk
- Sarcopenia roughly doubles death risk (3.5× with frailty) and perimenopause stacks anabolic resistance on top, exactly when women are told to fear the foods that defend them
By the end, you'll understand the mTOR and IGF-1 science well enough that nobody online can scare you off your own dinner, plus a simple Monday-morning plan: adequate protein, front-loaded, built on minimally processed foods, with heavy lifting to match.
