Welcome to the Dr. Berg's Healthy Keto and Interminute Fasting podcast, where Dr. Berg takes you on the journey for the truth about getting healthy and losing healthy weight.

So I get this question quite frequently. How much weight can a person actually lose when they're fasting?

Now I just want to mention the difference between doing the ketogenic diet, okay, and you

have fasting over here.

And if you combine them, it's a whole different thing. But if you're

just doing the ketogenic diet alone where you're lowering your carbs, the most that you can lose

per week is about two pounds of fat per week if you're healthy. But what if you're fasting every day?

How much can you lose? You potentially could lose a lot more.

You can lose a half a pound a day, and that would be 0.227 kilograms for those Europeans,

or that comes out to 3.5 pounds loss per week, or 1.58 kilograms per week. Now Now just realize that this is the best case scenario. You're not

going to lose more than this. You have to have a really healthy metabolism to be able to lose that

much. Now if you're just starting out, you're probably going to lose anywhere between 7 to 15 pounds for the first week.

And that's pretty much going to happen on just about any diet that you do that lowers the carbs.

Why? Because you're going to lose a ton of water weight. Where is the water weight coming from?

It's coming from the stored glucose as

glycrogen. So there's 3 to 3.8 grams of water in every gram of glucose if it's stored as

glycogen. So glycogen, which is stored glucose in your liver and your muscles, is like a fluid-filled sponge. And when you're doing fasting, you're going to use up the glycogen in your liver, not your muscles, but in the liver, and some other places, to the point where you're not going to have very much glycogen in your liver, and you're going to dump a lot of water. I think most people

knew that, but if you didn't, that's what it is. Now, there are all sorts of variables that go along

with this. Depending on your age, if you're 18 years old, you're going to lose a heck of a lot more

than a 65-year-old. So you have your activity level, your exercise level. If you're male or female, females have

more estrogen. It makes it more difficult to lose weight. You have how strong your metabolism is,

how healthy you are, and then you have what you eat when you break the fast. I think that's really
