My scale plays mean jokes with me if I try to check out my progress before my weigh-in day.
Today it says I am up over Monday's weigh-in; I can't be as I stuck to my plan, exercised and drank all my water daily.
In the 5 months I have been on my program, I have lost every single week (knock on wood!).
So I finally realized I can't trust my scale/body while it works it's weekly magic out!
Keep your eye on the prize, don't go off your plan just because of the scale!
