I'm sort of an expert at starting Atkins, since I have restarted so many times (four vacations last year). Plan to have lots of food around the first few days, and drink plenty of water. You won't feel so great right away, and it really does help to eat more. Keeping full will help you stay on program too, until it gets easier (it does!).
I usually have a couple of eggs and a couple of pieces of bacon, keeps me satisfied for a long time. If I'm not being really strict (ie induction), I might have them on a lo carb tortilla with some salsa and cheese, or on alternate days have some hi fiber, lo carb cereal with fruit. You'll have to visit a store with lo carb items to get these, but they are becoming more available. Lunch is usually leftover dinner from the night before, snack is a small handful of nuts or sometimes a piece of hard cheese, dinner is almost always a big salad with protein. And maybe a side of veggies. Watch the carbs in the salad dressing. Good luck! Diana
