It's flying out the door

On the weekend I decided I needed to keep a closer eye on my personal calories in/calories out equation.  So I've started using a food diary again and trying to include a bit more physical activity in my days.  And as an objective measure of results, I weighed myself and took measurements.  Anyway, I stood on the scales again this evening and according to them I've lost 3kg in 3 days!  Not sure whether to believe them or not (Peter just gave me a new set of scales as a late wedding anniversary present, so we will see what they say in a weeks time).
