My Mum has has type 2 diabetes, which she has had since her early 60s, now almost 90. She has managed it with diet and it was not an issue until recently, as balancing her glucose levels is difficult alongside other health challenges, including keeping weight on. I was warned I had insulin resistance by my gynaecologist and have been able to, hopefully, avoid diabetes through dietary adjustments. All my Mums siblings had diabetes, but didn't adjust their diets. They are no longer alive, but Mum is! So keep doing what you are doing. You are following the most healthy diet, hopefully, that everyone should follow.
