Hi Ya Sav,
I have just started CD however did the LL last year and they are pretty much the same. Most people lose about a stone a month, in the first month it can be anything up to 2 stone, just check out some of the progress people add under thier tickers. Men can lose slightly quicker than us girlies, but a stone a month is fab.
Good luck and enjoy the feeling your gonna get every week stepping on those scales.
