I know of one middle aged man who had been deemed to be T1 by a hospital team of doctors but when he met my GP who knew better and had been informed by the man's wife that the man had felt fruit juices were healthy, that meant all the man really needed was an education in the wisdom of eating a low carbohydrate diet. The end result is the man lost all the weight he had gained by having been put on insulin by the errant hospital team. The man is now back to being non diabetic and is just eating in a wiser fashion. He was a T2 wrongly classed as a T1 because his initial testing had been so astronomically high that the hospital team figured he must have lost all ability to make insulin. Wrong assumption, that a c-peptide test could have corrected, if they had only bothered to measure that to find out.
Another woman I met about 10 years ago had at that point gained weight from having for a long while been on the drug Glyburide which forces more insulin production which as we all know can make a person gain weight. So in 2006 she had been on no injections of insulin, but had been told back then that she would need to be on insulin as her control was not very good. Well in Feb 2014 I heard from her and by that time she had been increased to 4 separate doses of 30u each, so 120u per day of insulin. She had neuropathy at that time which can occur relatively easily when taking Metformin with a poor choice of supplements as Metformin drives down B12. In less than three months on a much wiser choice of a higher quality multi vitamin mineral, her need for insulin had dropped to 83u per day in total. Now, a few weeks ago she told me she had found a doctor's weight loss clinic whose team had helped her lose over 40 lbs and she was now not on any insulin and no longer on Metformin. So that is how a T2 can become a non diabetic, but that does not mean they can eat whatever they like in large quantities. Being healthy does take effort.
So, if every overweight diabetic were actually taught properly how to eat in a low carbohydrate fashion and if they still have a robust c-peptide test result which can measure their own insulin making ability, it certainly is possible to reverse diabetes by giving the individuals a better education. Exercise must also be part of that plan.
So, indeed let's recognize that the medical system which does not bother to train people in the value of how to eat properly would much rather gain a patient for life by telling them they are diabetic which then causes them to gain large amounts of weight as it is so common that the low carbohydrate way of eating is not properly embraced.
There are indeed more diabetics around because of this lack of proper knowledge.
