I hope that you will eventually get your husband to watch some of the Diabetes related videos on DietDoctor. Dr Fung makes it perfectly clear that controlling BG through insulin does little for preventing the eventual LT side effects...the risk of amputation, eye problems, go away by lowering insulin, not adding more. My own Doctor, Eric Westman, has good videos there how he treats diabetics in his clinic. Tons of good info about diabetes on that website and more inspiring stories. Also this 18 minute TedTalk: https://m.youtube.com/watch?v=da1vvigy5tQ. Clear, simple, how Diabetes happens and what to eat to correct it.
I am a fan of the pantry clean-out method to help begin LC...give away the biscuits, crackers, pastas, sweets...a clean slate. Hard, DH may fight that, but it’s a NEW Year! All the best for a healthy one,
