Thanks for the neg!

Last i checked fat is broken down into sugar as well... and unlike carbs fat blocks insulin from doing it's work, if insulin aint working due to fat, glucose is stuck in the blood.
if you're fat enough to can have high blood glucose while starving.
The reason glucose is "stuck in the blood" in diabetes is that there isn't sufficient insulin available to digest the carbohydrates eaten. Either because in type 1 the pancreas just doesnt make it, or in type 2 where the body makes it, but the insulin resistance means a much larger quantity of insulin is needed to do the same job.
So if you eat lots of carbohydrates you are putting lots of glucose in the blood at once and saying to the pancreas "here you go then, sort that lot". That is the reason for high blood sugars - the pancreas cant do its job! Fat, if eaten with carbohydrates won't "block the insulin from doing its job" at all, it will however slow down the digestion of the carbohydrates. A diet based on protein/veg etc, the body will of course still break it down to get the energy it needs, but there wont be mountains of glucose sat hanging around in the bloodstream waiting to be sorted out.
As for the last bit its nothing to do with "if you're fat enough" at all. Do you realise that before the discovery of insulin type 1 diabetics simply starved to death? The whole reason blood glucose is high without sufficient insulin is that if the glucose is sat around in the bloodstream and the body cant use it for energy, the body will starve. People literally starved to death whilst having high blood glucose, and they would not have been fat at all - starving means they would have lost lots of weight - their bodies couldnt get any energy from the food theyre eating.
This is the reason that eating smaller portions of carbohydrates and more of other nutrients would be better - a diabetics body cant efficiently deal with carbohydrates, it's just not efficient enough at breaking them down for energy and they sit around in the blood stream for far too long, causing high blood sugar. As an insulin dependent diabetic i only take insulin for the carbohydrates i eat, the body can deal with energy from other sources without insulin, so makes sense to me that those are better sources of energy.
Almasy and the OP - have you had a glucose tolerance test?
