Metabolic flexibility is the ability of the human body to increase use of fuels that are more available in the diet, depending on what is available. It's basically how our bodies are biologically designed to run. Think about it this way-- we haven't always had fast and convenient access to food. Throughout our history as a species, we've gone through feasts and famines-- periods of prolonged lack of resources between "meals," depending on factors such as environment/soil conditions, seasons, and food availability. Our bodies had to adapt, and the way they did this was by switching between fuel sources as a means of survival.

Metabolic flexibility is possible in our modern world of abundance, but it takes a little  work. In this episode, I break down the science of metabolic flexibility, from insulin and glucagon's role in blood sugar homeostasis, and mitochondria levels. I also provide practical things you can implement in your life, today, to improve your metabolic flexibility.
