For snacks, I'd say things that have alot of protein and/or fiber. Or, what I do and should do more, is bake those Fiber One muffins. I use the packets, and also put two scoops of protein powder in the mix. Any flavor taste good. We have blueberry mix and chocolate powder. You can't even really taste the powder, and it's a really satisfying snack. Protein bars are good snacks, but they do not taste good, and you need to drink a glass of water with them. If you find one that tastes good, let me know!!! (or anyone for that matter)

As far as the workout, I wouldn't trust it to get you total shape. And your first week is going to be hell on earth. At first I was doing a mix of lifting and cardio for about 8 months. The past 3 months I've been doing all cardio, and now just started a weight lifting class. I'm sore! It sucks, but it'll be worth it in 10 pounds. I'm also taking a "Fat Burner" twice a day. It doesn't have caffiene in it, it just tells your body to burn the stored fat you have. If you decide to take a weight lose supplement, remember it's just there to aid you, not do the job. I get mine from a place called Juice It Up. It's the fat burner that they put in smoothies, so I feel really comfortable with it.

As long as you keep an open mind and don't think that there's only one way to get in shape, you won't have a problem. There's always tweaks you can do to exercises that might or might not be better for you.

Sorry for the rambling, working out is one of my favorite things to talk about, lol.
