Tippy,
First of all let me say I am sorry you and your husband are going through this. It is hard to make the necessary adjustments for everyone, but I think it's harder on men...they are more stubborn and set in their ways. Does that sound sexist?
I have another possible resource for you. A magazine called Diabetic Cooking. It's chock full of recipes, including low carb, and it usually has an article or two on current medical news associated with diabetes.
As was previously mentioned, there are a million sites on the net and even more books available at the library and bookstores.
I don't think there is an easy way to make a change in your diet unless you want to. Your dh's desire to stay well has to be as strong as our desire to be thin. Strong desire and fear brought about the change in my diet and exercise routine. No one in my family could make dieting easier on me. I don't think you should put that burden on yourself. Just be supportive. Get educated. Eat healthy together. Hold hands and take long walks together and pray the your husband will understand the importance of it all.
My prayers are with you both,
MB
