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.

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