I read that Denise' long blog over the weekend, which you posted. Thank you. To be honest, I wouldn't dare recommend rice to a diabetic. I would much rather go with finding pure fructose than pure glucose from rice. If I were the diabetic, I would be willing to try it, but when it's for somebody else, there's Murphy's Law
I know it sounds counter intuitive, but it's not. You want to reverse insulin resistance = you want to improve glucose metabolism.
Reducing carbs may work for most people because it kinda goes around that insulin resistance. It says "oh well your metabolism is broken, too bad too late can't fixe it. nope. have high fat instead". It's quite dangerous in my opinion and much more sustainable to slowly progress towards a very low fat diet.
It's possible that the super restrictive diet and very high fruit juice alongside rice may have been risky for some patients. There must be an easier way :) Anyways, 6 chances out of 10 to be treated in less than a month vs. medication their whole life.
