True-love is a type 2 diabetic who has the whole thing under great control. The most obvious symptom he had before he was diagnosed was lethargy. He has never been overweight and actually prefers a low GI diet. Adding an excercise program and eliminating a very few things from his diet was all he needed to do.
It's not so easy for most of us but it seems the way to go even for non-diabetics.
The latest research shows that type 2 diabetes occurs in people with a genetic predisposition, so that a poor diet is not a cause, but is probably a factor in determining how soon you develop it. That is if you have the right (or wrong depending on how you view it) set of genes.
Having said that, I think we can all benefit from the experience of diabetics. Low GI diet, regular exercise.
Good luck Dave. You've already shown you can do it. Forgive yourself for the small lapse. Every time I have a fall like that I can't believe I did it either. Cheers Joy
