I'm allergic oats, iodine, anything with citric acid, and I'm lactose intolerant so what can I eat to lose weight and stay healthy?

Not all is allergy. First, i need more info. What is y our allergy to iodine? If you had a problem with contrast material for x rays, that is a special case. Lactose intolerance is inability to digest mil sugar (lactose); you can still eat cheese; most people tolerate yogurt, where lactose is already broken down. If citric acid bothers you, you may have a problem with stomach acid. See an allergist first, .
