Are high ketones during fasting dangerous?

Ketoacidosis is a serious health concern that can have devastating health consequences. However, having ketones in the blood during a fast is rarely cause for alarm. In fact, it is often an indicator that your body is burning fat.

Ketoacidosis primarily happens to diabetics who don’t take the right amount of insulin. Ketoacidosis is very different from nutritional ketosis, which is beneficial and will result in ketone levels in the body being raised.
