I think the tape measure is WAY more important than the scale. If someone had told me before I started Fat Flush I could have 150 pounds OR size 12, but not both, I would have jumped at the size 12 thing 'cause I'd never been smaller than 14 as an adult.
So the fact that I'm now wearing size 6-8 is a complete and wonderful surprise. The only other thing I'd like to add to this discussion is to make sure you are eating enough to support your current exercise levels. Some newbies make the mistake of exercising TOO much for their current calorie levels and end up stalling their metabolism.
