Oh, you are not alone! I have skipped a weekly weigh in for that very reason...and that is ok, because as long as you are changing your eating, exercising and improving your lifestyle you are on target. Remember this is not a race, it is a healthy lifestyle change! It could be a big loss or a little, but you still succeeded. Did you take your measurements? That is another way to measure success. Maybe you need to weigh in monthly? Think about it. And remember the big losses are usually in the beginning, so don't get caught in the trap of thinking it will always be fast.
