I may have misread your post - apologies if I have. Are you saying that carbs are essential for type 2 for energy? I am a type 2 who is now now diabetes resolved and no longer on insulin and have a maximum of 20g of carbs a day.
I teach pilates six days a week and go for long walks with my dogs. In fact I have loads more energy than when I did eat carbs.
Apologies if I am derailing this thread.
The issue many don't know, T2D's especially, is ALL HUMAN LIFE is powered by blood glucose. Insulin then produces a 'battery' that makes every cell work. Over at least 98% of people get ALL their blood glucose from the Automatic Conversion of Carbs into Glucose. Without carbs and blood glucose YOUR DEAD!
A complex way to get blood glucose is increasing protein (too much will make 'your intestines block' to say it nicely). That way the body switches and uses more fat, rather than utterly concentrating on carbs, (it can also use proteins) this process goes via the liver not the pancreas.
Resting a T2D's Pancreas, but T1D's can via this way get too much protein and produce a toxin (Ketones we can't expel - complex!).
**A balance in food, as in life is always the key, It's just finding 'our' bodies balance.
>So sugar acts super fast, but Carbs metabolise slower, but into Blood Glucose too THAT POWERS EVERY HUMAN CELL.
So if T1D (unless you've a low mmol/L readinh) or T2D's, reducing Carbs and increasing Protein (gently) makes the body find needed Blood Glucose from fat and protein, not Carbs (before we found sugar cane growing).
(Search Engine: NHS Carbohydrates and scroll to Energy). For T1D's as the years pass its all hyper complex, but you remember it as its critical! T2D's can control blood glucose by reducing carbs and increasing protein - Gently, Gradually, and monitor blood readings. "The human body is a complex chemistry machine".. {Re Sucralose I think it tastes better, and some have side effects or are allergic to aspartame - and as its not cane sugar, it does not go in hyper fast).
Just a walk, Exercise is good for all, it even increases 'happy' hormones in the brain! Good for the heart and blood.. Again balance and keep a close eye on blood readings. But just know its not just grown cane sugar that is sugar - the body creates it and needs it, but all in balance. (NHS Carbohydrates, Energy).
