We're trying a more Atkins-type (with low fat) diet and he is feeling much better. Amazingly so (and he's still eating carbs - 40g-60g per meal as per the US Diabeties thing recommendation), anyway, it seems to be working.
The most amazing thing to me is that he is not only willing to change but has done so!
However, if anyone has any fave recepies, please do post! McJag, I keep meaning to look for Angelfood cake mix in the supermarket, but I haven't remembered yet! Doh!!!
