Hey kgood!
TOM can artificially raise weight--I say artificially because it's water weight. 2-3 pounds is not unusual, but only time will tell whether that's the cause of your weight not changing.
It would be nice if weight loss were a smooth, straight line going down, but it doesn't work that way. Drat! Some weeks you'll drop more, some less, and some not at all. Some weeks you may even go up a little, even though you haven't changed what you've been doing.
Don't despair! Keep going! Stick with it!
