for your liver to deplete all their glycogen levels.

And that all depends on- 12 to 36.

It all depends on your diet.

If you're eating a lot of carbs, refined carbs, it's going to be more like 36 hours.

If you're eating more of a whole foods type of diets, like protein, lean meats, you know, poultry, fish, vegetables, that's glycogen is going to be depleted after like 12 hours.

And then, you know, anything beyond that, you're going to be in what's called like ketosis.

So for me, I usually stop eating dinner 6 p.m.

Usually, sometimes, you know, social obligations push that a little bit later.

And I don't eat my first meal until around noon.

So for me, I'm fasting for about, you know, 18 hours, right?

Now, there's the 16-8 where you basically stop

eating your meal around 8 p.m.

and don't eat your first meal until noon.

Or, no, I mean, 8 p.m.

Or you could start, if you stop at 6 p.m., then 2 p.m.

It depends, right?

So whatever works for you.

Some people, they have to wake up in the morning and eat breakfast.

Like I said, there is an adjustment period.

For me, it works really well.
