Ep. 94: How Stress Crashes Your Metabolism & Why Hormesis Is NOT The Answer (Stress & Mitochondria Part 2)

The Energy Balance Podcast

In this episode we discuss:

• Why uncoupling is harmful in certain contexts and how PUFA cause constant, low-level uncoupling

• The involvement of uncoupling, mitochondrial biogenesis, autophagy, heat shock proteins, and hypoxia-inducible factors in the stress response

• How stress prevents our mitochondria from effectively producing energy

• How chronic stress causes insulin resistance, high blood pressure, weight gain, depression, and cardiovascular disease

• How sugar and fat cravings result from stress and why listening to them is beneficial

• How adaptations to stress get passed on through generations
