About this episode

Dr. Eric Balcavage discusses why low energy and sluggish metabolism may not indicate broken physiology but rather adaptive responses to stress.

Episode 227: Why Your Metabolism Isn't Broken (And Why You're Still Tired) If you're struggling with fatigue, low energy, or a "slow metabolism," you've probably been told the same thing: Something must be wrong. Your thyroid is low. Your mitochondria aren't working. You must be deficient in something. So the solution becomes: take more thyroid hormone, add more supplements, and try to boost metabolism. But what if that entire model is wrong? In this episode of the Thyroid Answers Podcast , Dr. Eric Balcavage explains why low energy and sluggish metabolism are often not signs of broken physiology, but adaptive responses to stress and reduced capacity . You'll learn how your body actually produces energy, the difference between aerobic and anaerobic metabolism, and why your body may intentionally slow down metabolic output when it perceives stress. Dr. Balcavage also breaks down how physiologic and perceived stress impact mitochondrial function, why reduced T3 may be protective rather than dysfunctional, and how common lab interpretations often lead to the wrong treatment strategy. If you've been trying to "fix" your metabolism but still feel exhausted, this episode will help you…
