Quick basics are: think mainly non-processed and no manufactured foods. There is no point counting, but you are supposed to stop eating when you are "satisfied' (not *full*). You can have pasta, potatoes, or white rice once a day. No bread. You are, however, allowed 35 points a week, so you could get some of the "forbidden items" using points. They stress vegetables, fruits, meats, and non-fat dairy. There are some "starch" items you can have (polenta, barley and quinoa come to mind, there are more).
Rather confusing, but if you get a book, it's easier to figure out. I tried it for 2 weeks and diidn't lose anything. My instructor said that's what she did, too, but lost on the 3rd week.
