Reversing type 2 diabetes naturally is not scientifically unfounded at all. Look online in the right places and there is tons of people that have been able to stop taking all their insulin and metformin etc by fasting, compressing feeding windows, cutting out all carbs.

Even the ADA had to finally acknowledge this is possible in a statement back in 2021: https://diabetes.org/newsroom/international-experts-outline-...

It's not such a crazy idea really - You consume so many carbohydrates that you overproduce insulin and become insensitive to it in a vicious cycle. The more you fast, stay in a ketogenic metabolic status, reduce carbs and/or go zero carb, compress your feeding windows the more insulin sensitive you become.

There is no such thing as an essential carbohydrate. Your body can maintain your glucose needs by converting proteins into glucose. Fat and proteins are essential. Glucose is not it can be produce by liver.
