Vicky - obviously it depends on what figures you put in... but with my 141K high, and my 80K stabilisation for a few months (the only weight I can ever remember stabilising at actually!!), mine's always going to be higher than most.
If I do it now, forget what I once weighed, and don't mention the 80K, it would come down...
But then I might as well just use the BMI calculator which takes nothing into account!
One of our newbies - I forget which one - is aiming for a 21.? BMI which surprised me.
