Not me personally, but my brother in law did. He is mentally disabled but, has enough going for him to be able to live on his own and work as a grocery store stocker, anyway, he ignored everything until he had a heart attack in his thirties, had to have a new heart valve put in and was extremely overweight. That is how he was diagnosed. My husband, his brother, went and stayed with him while he recuperated and taught him how to eat keto with some very basic recipes and guidelines. He's been insulin free for years now. ❤
