Adding weight to profile?

I see everyone has a small grey oval on the top right hand side of they're posts which shows how much weight they've lost, can someone tell me how to do this please?Thanks.

Hi Hidden

The grey box next to your name is where the admin team award you badges as you lose weight. You have a newbie badge at the moment but once you have lost 7lbs we will change your badge. After that you get one for every stone you lose.

No need to be sorry it's fine. Any questions just shout out.
