Why am I seeing no change in my weight, nor in inches lost? (Please see details.)

As of April 11, I have a new job. Yay! In my previous job, I (mostly) sat from about 8:30AM to 4:00PM and took a 45 minute lunch, also sitting. Now, I’m on my feet from 7:00AM to 2:30 or 3:00PM with a 30 minute lunch. That lunch is the only time I’m sitting during the day. I am also up and down a flight (one story) of stairs at various times of the day. (Typically a dozen or so trips, with a “trip” being both up and down)

My caloric intake has not changed since after my first week there. We get fed lunch. Initially I hit the soup and sandwich lunch pretty hard. Once I thought about the calories in the soup (because we’re talking creamed soup here) I quit that. My breakfast and dinner have not changed from my far more sedentary job days. My lunch is now healthier most days than it was as I’m doing salad with chicken, no soup, one slice of bread and one slice of cheese. I’m still drinking the same amount of coffee and water as I did before.

The only thing that has been significantly different is that my stress level started out higher. Over the last 3 weeks, that has lessened quite a bit.

So here’s what I don’t understand: more activity, the same (and sometimes fewer) calories but neither the tape measure nor the scale are moving. There are no changes in how my clothes fit. What’s not adding up or subtracting! here?
