Welcome to the Dr. Berg, Healthy Kito and Intermediate fasting podcast.

Now your host, the man taking your health to a whole new level.

Dr Eric Berg.

So a lot of times I'll get feedback from people that have this idea

that your body, especially your brain,

can only run on glucose, right? That's the primary fuel. That is absolutely not true.

You can run your body on ketones and other types of fuel. So ketones generally will provide about 40 to 70 percent of the fuel in the body.

So then the question is what other fuel is going to make up the difference because if key tones are

only providing 40 percent, what else are we going to run our body

on? Well, there's always going to be a small amount of glucose, but your body can run on something

called fatty acids. So the fat will turn into ketones and fatty acids. Okay? So you can still use that, a small

amount of something called lactate, but also glucose. So with the brain it is a little bit different because you could run

70% of the brain on ketones and the rest is going to be either lactate or glucose. Okay. So the question is where are you going to get the glucose if you don't

want to do carbohydrates? Well your body can make glucose and that process is called gluconeogenesis, the making of new glucose.

Where does it get it from?

Fat and protein.
