Hi, I have been diagnosed as having pre diabetes. My Mum is type2 and has been for some years as was my Grandma. I would like to reverse this so that I don't go down the same path which I feel is inevitable. I try to avoid bread, pastry, crisps etc, but am finding when I go out say for the day or a lot of walking I feel faint. What do I eat to combat this? However I swim most days for an hour and half and don't suffer from feeling faint after! Any advice.
