It's a synthetic but realistic 2.2 lb of fat . It keeps me motivated when it's going slow. I have even been known to keep it in the fridge to keep me out of the fridge !
My little lady now weighs 19 and half lbs. I have lost 27lbs.. It staggers me that I have lost half a stone more than she weighs! My arms nearly drop off when I hold her now!
I wondered if that was what the pic was! I've been known to pick up bags of sugar in the supermarket to remind myself how much 1kg actually weighs but that looks very realistic!
