Georgia Davies was said to have made 'dramatic progress'
A teenager has been praised for losing more than 12 stone, seven months after joining a US weight loss programme.
Georgia Davies, 16, from Aberdare in south Wales weighed 33st (209kg) when she flew to Wellspring Academy, a boarding school for weight loss.
She had earlier been warned by UK doctors that her weight could kill her.
But now Georgia has seen her blood pressure drop while her "confidence, self-esteem and smile have returned" said academy spokesman John Gordon.
Since she enrolled at the academy in North Carolina last September, Georgia has lost nearly half a stone a week.
She is also no longer suffering from diabetes and her blood pressure and heart rate are now within the normal range for a teenager.
Mr Gordon, chief marketing and business development officer for Wellspring Academy, said: "This is a remarkable result that can be attributed to Georgia's consistent commitment and a programme that enables teens to make healthy lifestyle changes."
Georgia was labelled as "Britain's fattest teen" in a newspaper story in August 2008.

She told The Sun newspaper on Monday: "Last Easter, I ate 12 chocolate eggs. This Easter I'm going on a picnic near a beautiful waterfall. I'll do lots of walking and eat healthy food. I'm really happy with my life now."
Georgia had previously told the newspaper of how she began comfort-eating at the age of five after her father died from emphysema. By the age of seven she already weighed 11 stone.
Wellspring Academy, which is sponsoring Georgia to board for one year, said she was unable to get funding within the UK to extend her stay.
Mr Gordon said: "While Georgia has made dramatic progress she still has 11 stone to lose in order to reach her healthy weight.
"She also requires additional behavioural training and work to help ensure her success continues long term."
Lynda Williams, nurse director at Rhondda Cynon Taff Teaching Local Health Board congratulated Georgia on her achievement and said they would look at her needs if and when she came back to live in the area.
She added: "We would like to reassure Georgia and her family that should Georgia return to Rhondda Cynon Taff, we will assess her healthcare needs at that time and ensure that measures are put in place to help her maintain her excellent progress."
