“Something else to avoid is super high protein because mTOR, it can be activated but you don't want to activate it all the time. 'Cause it's not going to turn on the autophagy, the defenses to recycle proteins.”
Main Takeaways:
- Excessive protein intake can lead to overactivation of mTOR, which inhibits autophagy.
- Autophagy is a cellular process important for recycling proteins and maintaining cellular health.
