This is where a lot of diabetics 'in the wild' beg to differ fairly bigtime with the NHS. I have yet to find a piece of reliable info from a sensible source that proves - to me I hasten to add - that anybody diabetic or not actually needs carbs in their diet in the first place.
It's a handy source of instant satisfaction in the tum, I'll grant you that. But most people find after trying it that they can feel full a lot longer on protein than they can on carbs. "Go To Work on an Egg" the egg marketing board told me every half-hour or so during my childhood - well, after ITV was invented anyway, LOL - and unlike Consulate, which weren't 'pure as a mountain stream' at all - the Egg people actually were correct.
How on earth is it that if we can't exist without the Carb, when ultra-low carbing - Atkins diet gone mad - diabetics find their bodies make/grab glucose from both protein and fat? Less of it than from carbs, 50% and 20% is it? and yes the body has to work harder to convert those things, whereas carb is easy for it. Maybe that's one of the reasons why you get fat when eating shedloads of carbs? - cos your body ain't working so hard. Hey, maybe it encases your internal organs in fat - Oh yes, so it does!
Oh, maybe that was how the hunter-gatherers of yore managed to exist - the occasional woolly mammoth, padded out with whatever nuts and berries they could pick from the hedgerows. No spuds, no wheat (= no flour, pasta, bread, pastry etc) no spuds, protein and minimal carbs, plus a smallish amount of fat and other nutrients included in any of the three ...
Oh well, your meter will tell the story that your A1c probably won't.
Many people buy strips from eBay. I hate anyone having to do this because it shouldn't be necessary in the first place and it makes me cross!
