If you've been listening to Evidence Radio for any length of time, you'll know that calories count, and macronutrients matter.

If you're an athlete, this is especially true.

You need to eat enough to perform at your best, but the amount of protein, carbohydrate, and fat you eat is also important. If you aren't able to properly tap into your carbohydrate and fat stores, you may not perform as well. This is mainly true for endurance athletes, but it might be important for strength athletes, too.

In this episode of Evidence Radio, Dr. Mike Nelson explains how to increase your ability to "burn" fat and carbohydrate to perform better.
