[QUOTE="NoCrbs4Me, post: 1035565, member: 113206"] For type 1 diabetes, the immune system attacks and destroys the beta cells and you basically don't produce any insulin, although there can be a honeymoon period where there is still some beta cell function. This is not caused by eating much carbs. For type 2 diabetes, the beta cells work fine, but due to insulin resistance must pump out extra insulin to get blood glucose at the right levels. Eventually, however, the insulin resistance becomes too much for the amount of insulin the pancreas can pump out and blood glucose levels rise. And after many years of maximum pumpage, beta cells start to die. As I said before, for years before blood glucose levels reach diabetic levels, the pancreas is pumping out excessive amounts of insulin. The majority of obese people likely have insulin resistance, just not elevated blood glucose. I would also suspect that your obese friend does not have non-diabetic blood glucose levels. And for all you know maybe he does have diabetes. You should ask him what his fasting blood glucose and his HbA1c are. Maybe he hasn't even been tested for diabetes. Also, I don't think Fung has said that being fat causes type 2 diabetes. Being overweight is just a symptom of insulin resistance. But, not all people are overweight due to insulin resistance.
