Hi shortandfluffy! i use TDP too and their protein, sugars, carbs, sodium, etc. levels are a good estimate but not an exact science. It must also be based on height because my fiber is 21g. However, I just read an article that said women should aim for 21-25 grams a day so I think that those levels must be based on the lowest recommended dose and then adjusted for height. Not really sure, but that's what it seems like to me. I always go over sugar, but it's all from fruit sooo I don't really think much of it.
Anyhoo, my "feel full foods" are popcorn and lentil soup. Food network's Giada DeLaurentis (sp?) has a lentil soup recipe that I use but I don't add salt because I don't like/need it. Usually if I'm feeling hungry and want something unhealthy, I tell myself "first, eat a bowl of soup and then if I'm hungry, I'll eat whatever I want" but then I'm not hungry after I eat the soup. It has celery, carrots, tomatoes, and lentils so it is pretty darn healthy and low calorie. and filling! I also just bought a can of garbanzo beans to make roasted chickpeas to munch on but I haven't tried it yet. (Sounds yummy though! Just a dash of olive oil tossed with cumin, chile, and cayenne and then baked) Also, lately I've been feeling lazy so I've just been cooking 1/2 cup lentils with a can of tomatoes with chiles and a little water, and then eat like a cup of it for a meal. I've had it for lunch and dinner today and it's been pretty filling. Have you tried couscous before? it's a complex carb so that would help you stay full longer. I like it with hot sauce on it, but i've yet to meet anyone else who does that.

I like spicy foods! beans, legumes, and whole grains are really filling, low calorie, and high in fiber and protein. You can't really go wrong with them!
