Could I lose weight from doing this?

I have recently got a new job. It is a very hardworking job at a country store. I have gone from sitting at home on the couch all the time to washing dishes, sweeping, cleaning, cash register, taking orders at the drive through window, making sandwiches and plate lunches (we cook a lot! I'm from the south and we make lots of plate lunches), running back and forth stocking the freezers and deli, etc... I am on my feet the whole entire time I work. I do not get a break and I do not get to sit down at all. I work around 25-30 hours a week. Since I went from doing absolutely nothing to working my butt off, could I possibly lose a little weight from this? I have been there for 2 weeks and my arms and legs get a little sore from sweeping, mixing large amounts of stuff, etc.. What do you think? I know its not exercise but could it help me? I also am not at home eating because I'm bored. I do not eat at all at work. Thanks!
