This is what I don't eat to lose weight and keep it off. Mind you, you won't lose it in a week, it takes a few to show up. No bread or the like.
No sugar, candy or sweets. No chips or other in that aisle.. No salt, you may use substitute salt. No soda of any kind. TRY to eat smaller portions, but I didn't see it made difference but helped not to pick between meals.
