Hi Tony and welcome, have a quick look at my "So you're thinking of starting Atkins" Thread on the stickies above, you could even cut and paste some of it as a shopping list. Basically look for as many green leaqf veggies you can find, Spinach, green cabbage, endive, chicory, broccolli, Pak Cho, Bok Choi, lettuce, the list is almost endless.
PS are you a bloke Tony or a girl Tony?
