A few days ago I put some books in a bag to try and physically experience the amount of weight I've lost - mostly because I don't yet feel very different. I've lost 21lbs so far.
The bag of books is so heavy that I can only just about pick it up and I certainly wouldn't want to carry it about all day. I realise that it must have been a bit easier when the weight was evenly distributed over my body rather than in a bag but still ....!
So now when I'm feeling a bit down-hearted that the weight isn't coming off quicker I just go an lift that bag and realise how far I've come, even though there is a long way to go yet.
