Why do we get tired? The afternoon crash usually isn't sleep, age, or laziness. It comes down to your metabolic capacity: your body's ability to produce energy, manage it, and recover from the demands placed on you. In this video, I break down the real biology of fatigue, from mitochondria and metabolic flexibility to insulin and why caffeine stops working, and how you can actually change it.

WHAT YOU'LL LEARN

Why your mitochondria set your energy ceiling, not your willpower
How you can carry thousands of calories of fuel and still crash
Insulin, Randle's glucose-fatty acid cycle, and afternoon brain fog
The adenosine mechanism behind caffeine, and why the 3rd coffee fails
How recovery, HRV, and mitochondrial biogenesis rebuild capacity

My name is Andrew Reid, and I'm the founder of Medgeeks. For 15 years, I've worked on two sides of the same problem: caring for patients and clients directly, and teaching the science of metabolism to the clinicians who treat them. I've had 100,000+ patient/client encounters, and 50,000+ people read my emails daily to get a handle on their metabolic health. Welcome to the Medgeeks community!
