Sodium isn't the only thing that causes water weight. Anything bulky that will stay bulky (examples - leafy vegetables don't, popcorn does) going through your gut will keep some water with it. You didn't go 7000 over burn and actually gain 2 pounds.

I think of sedentary as an office job, walking to/from the parking lot, around a little at work and some around the house. The calculators are for most people. Lightly active includes some exercise or a job that has you on your feet and moving around a lot.

I am going to try Pacer Pedometer on my phone. It syncs with mfp.
