Is protein aging you faster? What the latest research actually says

Is protein aging you faster? What the latest research actually says

879. Are you eating too much protein, or not enough? The honest answer is that the question itself is flawed, because there's no single number that fits everyone.

In this episode, Monica breaks down why protein needs shift across a lifetime. The mTOR "growth switch" inside your cells runs hot during childhood, powering the tissue-building that young bodies require. In your 30s and 40s, dialing protein back may nudge cells toward repair and cleanup instead. And after 50, when muscle naturally starts to decline, eating more actually helps preserve strength, mobility, and bone health well into later years.

She also puts the recent longevity headlines in context. A widely covered review of animal studies found that lower protein intake can extend lifespan in flies and rodents, yet those results don't map neatly onto human biology, where lifestyle, genetics, and the rest of your diet all shape how you grow older.

Monica offers a more grounded way to think about protein: match your intake to your age, sex, and activity level, and treat the current RDA as a floor rather than a goal.
