Mark has not been able to manage his weight for the last several years, and the doctor told him he now officially has type 2 diabetes. Elaine has paid close attention to her health, and the doctor told her she does not have type 2 diabetes and her health is normal. Whose body cells no longer respond normally to insulin?

Mark
