What Really Happens When You Fast?

Fasting is not just about weight loss. In this episode, Dr. Derrick Hines breaks down what actually happens inside your body when you stop eating. He explains the metabolic switch from glucose to fat, the rise in ketones, and why hitting the 72-hour mark unlocks autophagy, your body’s built-in cellular cleanup system. From reducing inflammation and improving insulin sensitivity to increasing natural stem cell production, fasting can act as a powerful metabolic reset. Dr. Hines also shares why he often prefers a fasting-mimicking approach over water-only fasting, especially to protect muscle and hormone balance.
