I have similar health challenges. Atkins works best for me. I can't tolerate any grains--and that includes rice. Read the books (Atkins is my first choice) and adapt what you read to your own particular health issues. I, for one, will never be able to add wheat, corn, sugar, beans, or rice back into my diet--even though most people can add them in on Maintenance. I have also learned that I can no longer tolerate tomato sauce or almonds (which were my favorite go-to low-carb snack). Life goes on--we need to learn from it.
