Is the current protein craze backed by science, or could eating too much protein actually accelerate aging?
With conflicting headlines everywhere — some experts recommending high protein for muscle retention, while a major new review suggests protein restriction may promote longevity – it’s easy to feel confused.
In this episode, I break down the latest research on protein restriction, mTOR, and longevity, while contrasting it with the crucial role muscle mass plays in healthy aging and preventing sarcopenia.
We look at why protein needs are not one-size-fits-all, how activity levels and age change your requirements, and what a common-sense approach looks like.
