I remember doing the Desmond course many years ago when I was first diagnosed, I must admit I didn’t find it totally helpful as at the time it promoted the Eat Well plate that recommends to eat carbs, this isn’t always the best thing for T2 diabetes as all carbs turn to sugar.
I don’t know if they still recommend this way of eating but I don’t think you’ll find many T2 on the forum who follow the Eat Well plate. The majority of our members use a lower carb diet to manage there diabetes.
