Welcome to the Dr. Berg's Healthy Keto and Interminate Fasting Podcast, where Dr.

Berg takes you on the journey for the truth about getting healthy and losing healthy weight.

So I want to talk about the hormone effects that can occur from doing a fast.

From really interesting research, I've put the link down below, comparing fasting for

two to seven days versus fasting from eight to twenty days.

So this would definitely be a longer fast compared to a shorter fast.

Now this data is not based on intermittent fasting, but at least you can get a concept

of what could happen to the endocrine system when you start to fast.

The first hormone that's involved is adrenaline.

This is a counter regulatory hormone.

So in other words, when you go to sleep at night and you're not eating, sometimes you're

going to get a release of glycogen.

So your body is going to use glycogen as fuel, especially if you haven't adapted to fat

burning.

What happens is the glucose is being released and the bloodstream is going up this way,

and then insulin comes in there and pushes it down.

And so there's counter regulatory hormones, adrenaline being one of them that will kick

in and release the sugar and raise the sugar back up to prevent a crash in blood sugars.

That can happen, especially if you are insulin resistance.

This is the main reason why people may feel that they're not sleeping that well when they're

doing fasting.

I realize that's a temporary situation.
