Try not to get too caught up in the finer details. I myself have sweet potatoes and rice about once a week. I also did a lot of reading back in the beginning, and couldn't understand why one site had a recipe for apple pie and cream!,,,,that would be a definite NO for me!
Make yourself a list of all the foods YOU want to eat, and come up with some menu ideas and a shopping list . Being prepared in the begining means you always have something in the fridge so you're less likely to cheat. Also stock up on some cooked meats and boiled eggs as well as fruit, nuts and seeds.
