One of the problems with rigidly following a restrictive or narrowly focused dietary protocol like low-carb or low-fat is when you go off-plan for whatever reason, you can get slapped.

For instance, if you’re a high-carber and miss a meal, you might find your energy levels plummeting, or if you’re a low-carber and indulge in some cake at a party, you might find yourself craving—and eating—every carb in sight.

Ideally, these things wouldn’t happen—our bodies would be able to adapt to varying dietary circumstances and maintain an even physiological keel. In other words, ideally our bodies would possess a fair amount of “metabolic flexibility.”

If you haven’t heard of metabolic flexibility, that’s understandable because few people have, and in this episode, Kurtis Frank explains what it is and how to improve it so our bodies can better shift between different fuel types and thus be more adaptable to whatever situations we find ourselves in.

In case you’re not familiar with Kurtis, he’s the co-founder and former lead researcher and writer of and the current Director of Research and Development for my supplement company Legion Athletics.

Here’s a sneak peek of what we talk about in this interview.

  • Insulin resistance and carb sensitivity as you age.
