It does look like you are on track. Hang in there and keep doing what you are doing! Maybe try to substitute the baked chips for some kind of fresh veggies? If I tend to eat too much sodium (the chips and popcorn pop out in the same day) I hang onto my water for the next few days.
Have you taken measurements yet? If not I'd suggest doing so. I take them every month & even the months where I don't lose as much on the scale I'm still losing a good bit in inches
It will come off! Like Susan has said...weight loss is not linear. If it was that would be awesome! It would not discourage so many women....we are very much into instant gratification

A 2 pound a week loss for 3 weeks is fantastic!
