Don’t completely eliminate foods that you actually LOVE.
Chances are that if you completely cut out foods you absolutely love, you’ll spring back into old eating habits pretty quickly. Unless your doctor informs you of a health condition that requires food elimination, or unless you choose to eliminate a food for personal reasons, let go of the idea of “bad” foods and learn to enjoy them in moderation instead. Pasta? Rice? A piece of chocolate cake? Enjoying these once in a while won’t derail all of your hard work and they aren’t “unhealthy” in proper portions. It is all about portion control...
Things do get a bit tricky with this “don’t” though. You have to figure out the best method of non-elimination for you. For example, if you keep your favorite food in the house and know you aren’t able to control how much you eat, then don’t keep it in the house. Instead, enjoy it only when you go out.
