Thanks everyone!  Quercus, I honestly don't know how it happens.  I've been shooting for 2 pounds a week, roughly, because that's a healthy rate to lose at.  I'm not even 'dieting.'  I mean, I don't pig out or anything like I used to, but I still basically do what I want (within reason).  I guess it's all the exercise.
Yesterday was pretty bad, from a food standpoint.  It was my mom's birthday and I made a cake with 3/4 of a cup of lard in it.  And frosting.  With more lard.  We also went out and ate A LOT of Italian food.  However, that was the only meal I had yesterday.  I was still probably in the 2500 calorie range though, but that's ok to do every once in a while.  My mom and I still managed to take our walk too.
Not sure what'll happen today.  I might take a day off from the exercise.  My feet are pretty sore.  I'm starting to get hungry too, so maybe I'll go upstairs and make a 'mater sandwich, even though I know I'll be disappointed because it's the middle of March and no tomato is a good tomato in March.  Not sure what will be for dinner tonight.
I need to go to the local rec center and buy a pass for fitness classes this week.  It's spring break and the ones through my university are cancelled, but I still want to go and get my exercise.  Definitely more expensive than my university, but it's only for a week and I think it's worth it.
