A friend of mine with type 2 diabetes has told me that his dietician told him that 50-60 gms of carbs per day is OK for someone who is pre-diabetic, but once you're diagnosed as type 2 diabetic, you need to eat 40 gms of carbs at each meal. Does anyone have any idea what this dietician is talking about? I have told him that I am skeptical about this information, but I'd like to show him some evidence that this advice is off the mark.
