Reply #1: Some of that is probably water weight.

There are several articles about it but here's one: http://extension.osu.edu/~news/story.php?id=3085

It's nice to get off to a good start, though, and your math sounds good for continuing to lose at the rate you calculated. Unfortunately, it's not an exact science and weight loss isn't usually linear. Some weeks, you might lose more and some weeks less, and the weight loss doesn't always match what you ate or how much you exercised so don't get discouraged. You can even reach a plateau where you don't lose at all for a few weeks -- it happens to everyone and there's lots of advice on the web on what to do about it.

Good luck and let us know how you're doing. And congratulations on a great first week! :yourock:
