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.

Most people think fatigue is a sleep problem. But the truth is… sleep is often just a symptom. In this episode, Zane breaks down why so many people—especially after 40—feel exhausted even when they're getting 7–8 hours of sleep. The real issue often comes from under-fueling, chronic fasting, low carb diets, and excessive training, which drive up stress hormones like cortisol and disrupt recovery. Zane shares the mistakes he made for years with fasted workouts, low-carb dieting, and overtraining, and

I recommended low-carb and intermittent fasting for nearly 20 years. Then my labs started telling a different story. In this episode, I break down why I stopped fasting, increased carbohydrates, lowered fat intake, and how that shift improved my fasting glucose, thyroid markers, LDL, sleep, and recovery.

In this episode of Healthy AF, Zane sits down with Dylan Gemelli for one of the most honest, wide-ranging conversations the show has had.

Low-carb might not be the health solution you think it is. After years of eating low-carb, fasting, and grinding through high-stress training, I started to notice something: my results were stalling, my sleep was off, and my labs were telling me I wasn’t as metabolically “healthy” as I thought. When I added carbs back in—real food carbs from fruit, honey, and roots—my energy, recovery, and hormone markers improved across the board. That shift led me back to today’s guest, Jay Feldman, a health
