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 explains how these habits can impact:

• Thyroid function • Testosterone levels • Sleep quality • HRV and recovery • Energy and mood

You'll also learn how to properly fuel your body for better energy, deeper sleep, and sustainable performance.

If you're tired all the time, this episode could completely change how you think about recovery.
