Welcome BigButchMistie....so glad you joined us!
I see you're already getting lots of good advice. I'm a big advocate of making small, progressive changes. Usually when we try to do everything at once, it's a lot harder to stick to.
Cutting out fast food and drinking more water is a fantastic place to start. Like Zimmy, I've become a huge fan of the greek yogurt. The first time I tried it, I didn't like it...but I tried a different brand and that made all the difference. I like the Oikos (Stoneyfield) Organic non-fat greek yogurt...although I like the ones with fruit at the bottom (and not the honey or fig flavors

). Sometimes it just takes experimenting.
If you're not a veggie fan, I'd say drinking a V8 is better than no veggies at all. I love puregrrl's idea about the soup too....you get all the goodness that way.
Stick around and keep trying different things. You've got lots of support here!
