My grandfather is a borderline type-2 diabetic, but has never been prescribed any meds. He has a serious sweet tooth and since he quit smoking 25 years ago and needless to say candy and cookies took over.
He's 5'8 and about 214, I put him on a keto diet and in a week he dropped 6 pounds. He has a lot of health problems, but he began to feel much better, however about 10 days into the diet he collapsed, pretty much out of nowhere. The dietician in the hospital told him that he should be eating a high carb diet.
Now I have no formal nutritional education, but that seems absurd to me. As she was explaining this to me, her statement was as follows, "the effect on blood sugar after gluconeogenesis is less stable than that of carbohyrdate intake."
I always thought that someone with type-2 diabetes should avoid carbohydrates and that through gluconeogenesis that person would be able to get the glucose they need, albeit much easier on the body.
