Hello and welcome.
A very good book for carb and calorie counting is Carbs & Cals, which you can order from Amazon - the proper book rather than the pocket version. It has thousands of food stuffs, all with photos on plates showing the portion sizes, with weights, carbs, calories, protein, fat, saturated fat and fibre. It was my bible when I first started.
Your husband has done brilliantly to lose that weight, so he (and you) have made a great start. Please have a good read round these forums. There are loads of idea, recipes, and suggestions. Basically, it is all about reducing carbs as much as possible. All carbs turn to sugar once in the system, so for diabetics Carbs = sugar. He could also try adding a bit more exercise. Even a 20 to 30 minute walk each day will help. Please feel free to join in with us and ask whatever you wish.
