Day 3 who moved my cheese

So, I'm trucking along and on track for my week 1. I went to Zumba today and sweated like a piglette, but I burned 700 calories according to my BodyBugg!!!!!!! And this morning, I walked 35 minutes, and my caloric intake was a little over 1800. I understand that one of my issues is cheese and by eating too much of it, I take in too much sodium. As I was at the grocery store yestery, I bought sliced cheese, shredded cheese and string cheese. So my goal next week will be to look for alternative for cheese. But this week, my main focus is to get more fruits and veggies, log my food, and walk at least 20 minutes. So far, so good:)
