Welcome to another episode of Revolution Health Radio. I’m Chris Kresser and today we’re going to answer a question from Jordan. So let’s give it a listen. Jordan: Hi Chris. Thank you for all that you do in helping people like myself. As a result of my HPA axis dysfunction, my metabolism is pretty much shot. I would love to exercise, but every time I do, my fatigue becomes exacerbated. I would love to hear your thoughts on exercise while suffering from adrenal fatigue. Thank you. Chris Kresser:  That’s a great question Jordan. It’s one that comes up a lot, particularly in my patient population, because I tend to see a lot of patients with HPA axis dysfunction. And for those of you that are not familiar with this term, this rather unwieldy term “HPA axis dysfunction,” or HPA-D, as we call it, the term you're probably familiar with that most people use for this condition is “adrenal fatigue.” For a lot of reasons that I won’t be going into in this particular podcast, I think adrenal fatigue is not an accurate description of this condition and is a bit of a misnomer. And the system that governs our response to stress and our tolerance of stress is the HPA axis, or the hypothalamic–pituitary–adrenal axis. And this is a system that often becomes dysfunctional when we’ve been exposed to chronic stress and inflammation and chronic illness, and so we call it HPA-D.

The concept of metabolic reserve

So before we jump into the specifics of my answer to Jordan's question, I want to introduce another important concept to you, which is metabolic reserve. So metabolic reserve is defined as the long-term capacity of cells, tissues, and organ systems to withstand repeated changes to physiological needs. So that's a mouthful, but we can use a couple of analogies to make it simpler to understand. So you can think of metabolic reserve like the charge level in a battery. So if the battery charge is full, your metabolic reserve is strong. You’ll be able to do a lot of work with whatever device that battery powers. But when that charge is depleted,
