Keto And Runners
If you took a class on nutrition, the very first thing you would learn is that there are three sources of calories: carbohydrates, fat, and protein.
As all runners know, carbohydrates are the primary fuel if you want to run fast. But there’s a problem with carbohydrates—your body just can’t store that many.
That’s why hitting the wall, or “bonking,” is such an issue in the marathon.
Once you run out of carbohydrates, your ability to produce energy drops dramatically and you have to slow down.
But, there’s a fourth source of energy that might offer a way out of this conundrum, and that is ketones.
