Message: <blockquote data-quote="sgm14" data-source="post: 2639145" data-attributes="member: 517358">I'm underweight so I don't fast very often, but sometimes it is unavoidable (like after a dentist's visit) and sometimes its not convenient to eat a normal meal at the normal time.So when I do fast, I sometimes end up going high (i.e. over 10) and on occasionally much higher (like 18 recently) and whilst it does not happen very often, it frustrates me that I don't handle it better.Whenever I have tried to eat a small snack to avoid this situation, quite often this does not work out either and my blood sugars still rises.I don't quite understand when or how your body decides it needs a liver dump.As I understand it, the theory seems to be that your blood sugars first fall and then your liver dumps glucose to avoid going low. But in practice it still happens to me even if my blood sugar never really falls. So if it is not based on low blood sugars, what is it based on? (It can't be that is is missing carbs otherwise the low-carb followers would be permanently high).How do you handle this?</blockquote>
