Hello Jenna: I'm sorry I don't know the answers to your questions. But I noticed no one had replied to your post. So I thought I would. You mentioned you switched jobs to one that involves a lot of physical activity. So perhaps that has something to do with your weight loss too.

Personally I seem to be having the opposite problem. I have been keeping myself really thin in recent years. But a while back I put on about 4 pounds. And I just don't seem to be able to get rid of it. It's as if my body has decided it likes the extra weight & it's not going to give it up without a fight! Anyway, I hope you're happy with the weight you've lost & that, assuming you are, you find you can keep it off.
