A.P.
I don't mean to be rude, but isn't this basically asking "tell me what to do to change?"
I think you're the only one that can answer that. You just change. Try it a different way the next time you're at the store. Go google "healthy eating".
But everyone is a "flavor" person, that's not unique. So "today", which is the word you wanted me to remember from the beginning - i assume b/c you're not really fully committted to change - today remember that you can eat healthy for just one day.
Don't worry about tomorrow, you can decide tomorrow if you want to snack. But today - just eat healthy.
