New to Using MFP Regularly

Hey everybody... my name's Andy. I'm a 19 year old college sophomore, and I'm a music education major (I play clarinet). I've always (as long as I can remember) been a bit overweight, but freshman year of college I gained about 50 pounds. It kept coming on... I remember noticing when I got up to 200 pounds and thinking that was ridiculous but still not doing anything; I ended up at a high of about 220. I didn't do anything about it until the beginning of 2011 (halfway through my sophomore year).

At the beginning of the year my mom and I started the "17 Day Diet". I don't know if any of you have heard of it, but it's a book written by some doctor. Apparently it resets your metabolism. It gave us a pretty specific regimen of what to eat, and I was fine with that. I'll eat what you tell me to eat if it'll make me lose weight. It worked. I lost a good amount of weight following that plan. I was on break between semesters at college when we started it (living at home), so it was easy. Then (beginning of February), I went back to school, living and eating on campus. I couldn't keep following the 17 day diet, but I took the principles I learned from it and good habits I'd developed to college. I continued drinking only water, not eating late, not eating huge portions, etc. From the beginning of February until this week I would eat (usually) a salad for one meal and either sushi or a chicken wrap for the other (the healthy choices here are limited...). Don't think I deprived myself though, I've enjoyed quite a few dinners out. So I continued losing weight every week. I started at the beginning of 2011 at 209.9 pounds, and I'm currently at 168 pounds. Note that this was all without exercising at all... I had the intention of exercising but, being busy, never got around to it.

Anyway, these past two weeks I lost 1.5 pounds and then 1 pound. I know this is good and healthy, but my weight loss is slowing down and I'm afraid that it's going to stop if I don't change what I'm doing. I think I may not be eating enough. So basically I'm starting to use MFP to make sure I eat enough, and to motivate me to exercise (my friend and I have been jogging around campus every day). I'm excited to see how I feel next Monday morning at my next weigh in.

Sorry this is so long, thanks for those of you who made it through!
