Welcome to the FTS forum Donna. I'm still kind of a newbie (only been here since July) so I'm gonna let Doug and Umpa answer most of your questions. All I can say is this forum is the bomb...there are great recipes, videos from Doug and Umpa and best of all, member support when you need it.
I try to eat less than the 20 carbs a day that are allowed. 15 or under a day for me works the best. The beans I use (learned about them here) is black soy beans, very low in carbs. You will learn how to read labels and eliminate high carb foods like pasta, rice, corn, peas etc.
You sound like me, having tried all the different ways to diet. The thing to remember is that FTS is going to be a "lifestyle change" and I don't consider it a diet. I love this way to eat and don't feel I have to give up a thing, unlike weight watchers, where I was constantly hungry and wanted something to eat.
Good Luck, your answers will be here shortly.
Suz
