Protein & Longevity
The protein paradox
High protein supports muscle mass — but excess animal protein activates mTOR, an aging accelerator. Timing and source matter.
Fact
mTOR: Growth vs longevity
mTOR is a nutrient sensor that promotes cell growth. It's great for building muscle, but chronically elevated mTOR accelerates aging. The key is cycling between growth and repair phases.

Aim for 1.2-1.6g/kg daily. Prioritize protein at breakfast, favor plant and fish sources, and cycle periods of higher and lower protein intake.
