Welcome, and congrats on your decision to take the plunge! I know what you mean; there are plenty of foods I thought were healthy, only to find out that they aren't allowed or are extremely limited. It just goes to show how misinformed most people are about nutrition, and just how much there is to learn! My sister called me up the other day to tell me that she was going to stop drinking pop and just drink juice from now on. I congratuated her on the pop, but I had to break the news to her that, aside from the lack of caffeine, she'd might as well be drinking the pop! And she LOOOOVES Subway subs, and of course they MUST be healthy since Jared says so. Never mind the high carbs (and fat, depending on the sauce!). She was pretty mad at me for that one.
In any case, look at it this way. Those "bad" foods will be allowed again eventually. Right now they're forcing you to end those old habits and turn off your cravings for them. During maintenance, they'll teach you how to choose those bad foods carefully without going overboard. They'll be back, and by then you'll know how to eat them without gaining!
Again, welcome to both the program and the boards, and best of luck achieving all of your weight loss goals
