The Dawn Phenomenon, or higher blood sugars during fasting does not mean you are doing anything wrong. It’s a normal occurrence. It just means that you have more work to do.
Some people have normal blood sugars except for the Dawn Phenomenon. This still indicates that there is too much sugar stuffed into their liver. They need to keep burning down that sugar. It means there is much more work to be done before they are cleared of their diabetes.
Think about it this way. The Dawn Phenomenon is simply moving sugar from body stores (liver) into the blood. That’s it. If your body stores are filled to bursting, then you will expel as much of that sugar as possible. By itself it is neither good nor bad. It is simply a marker that your body has too much sugar. Solution? Simple. Either don’t put any sugar in (LCHF) or burn it off (Fasting). Even better? LCHF + IF.
