48. The Real Reason Your Metabolism Slows After 40 It's Not Age

Most people believe your metabolism automatically slows down after 40.

But the science says something very different. In this episode of Healthy AF, Zane Griggs breaks down the truth about metabolism, aging, and why fat loss gets harder for many people after 40.

You'll learn why muscle loss, lifestyle habits, and hormone changes play a much bigger role than age itself — and what you can do to keep your metabolism strong for decades.

If you want better energy, improved body composition, and long-term metabolic health, this episode is a must watch.
