Schlep i was wondering, do you have type 2 diabetes by any chance?
Because I was thinking (on my walk to work this morning)...
that your blood sugar rise may have nothing to do with liver dumping, but more to do with type 2 diabetes.
In a normal person whilst they are fasting, they will become insulin resistant - this is so that the body preserves it's dwindling supply of glucose,and starts to utilise fat instead. As soon as they eat, (I think it's due to stimulation of the vagal nerve) then insulin resistance drops, and the body (muscles really) become ready to absorb the glucose from the meal.
people with type 2 lose this flexibility - so what happens is that they do not become insulin resistant enough when fasting to switch completely to fats, and they do not become insulin sensitive enough when they eat for their muscles to absorb all the glucose from food.
A similar thing happens when a type 2 exercises - a normal person becomes much more insulin sensitive when they exercise, while this response is blunted in someone with type 2.
so....
could it be that what is happening to you in the mornings, is that you are waking up - you are insulin resistant when you wake, and you go for a walk. The liver responds to the demand by releasing glucose, but your muscles remain insulin resistant and so can not absorb the glucose - leading to BG rising.
You can perform a simple experiment....
a snack before you walk should improve things - the food will help lower your insulin resistance, allowing your muscles to better utilise glucose.
(this all assuming that you have type 2 of course)
