I have had a lot of luck with sugar free and zero sugar products. I know they aren’t really good for you but I haven’t had an issue. But filling up on sugar free or zero sugar soda and juice has really helped me out these last few months.
I mainly just have to watch my sodium. So I can’t eat a lot of soup or other canned stuff. But if you can handle it then broth is good. Hot flavored tea is good too.
