I agree with eddiesgirl. Did you measure when you started? you might see changes there but not the scale. Also, the 3rd & 4th weeks are notoriously bad for not showing scale changes. Lots of posts have been done on this.

I started 1/25/04 and am still doing induction levels til I'm down another few lbs, then I'll start up the carb ladder.

I'm assuming you read your book (forgot to look before typing).

Be sure to get your water in, and don't panic it the scale doesn't co-operate every day.
