Cat, congratulations on that 50 lb. weight loss. That is already having both short-term and long-term benefits for you.
My wife is quite the sugar addict, and though she acknowledges my weight loss and improved blood test results, she’s quite resistant to change. She’s still essentially metabolicaly healthy, though overweight - it may be that she’s just not at a place, yet, where she’s receptive to a different diet. I don’t push hard - she knows the deal, and I think that eventually it will all work out.
I don’t need support, really - it’s more that I need to deal with my own compulsions and excessiveness.
Restaurants for me - when I’m staying with the program - are meat and low-carb vegetables.
