I'm not sure how to boost the lagging scale but I do know that weight loss takes some time to kick in. How long have you been on plan? It can take several weeks for all the eating right to kick in and for you to start seeing the outcome on the scale.
I know for me personally that my scale does not budge for almost 3 weeks at a time and then all of a sudden the scale drops almost 5lbs in a week for me. This happens to me most months and I know that those 3 weeks that the scale doesn't move I get so frustrated! You just gotta take it one day at a time, it will go down at some point
