There is one growth signal in your body that quietly controls how fast you age.

If it's too low, you will age faster.

If it's too high, you will accelerate aging too.

Yet, doctors never measure that!

It’s called IGF-1 (insulin-like growth factor 1) — and it’s massively influenced by the food you eat.

In today’s new video, I break down:

 How IGF-1 controls aging – why it speeds up some processes and protects others

 Muscle growth & strength – why you need enough IGF-1 if you want to build or maintain muscle

 Bone mass as you age – how IGF-1 helps prevent the slow, silent loss of bone density

 The “sweet spot” – why both too high and too low IGF-1 can be a problem.

I will touch under 65 and over age 65.
