Lady Arabella Onslow, 41, a GP at Market Street Medical Practice, Kirkby-in-Furness, was given the award at a ceremony in London’s Marriott Hotel, after losing 10 stone.
'There are a lot of unhealthy and overweight doctors and nurses in the NHS. It is a very sedentary lifestyle and the accessibility of high-density food is massive,' she said.
'People forget that we are just like everybody else and how you live your life doesn’t necessarily correspond with your work.'
Lady Onslow weighed 21 stone 10 pounds and wore a size 26. She now weighs 11 stone 10 pounds and is a size 12.
'Although I lost weight for personal reasons, I applied for the award to inspire other GPs and give them the mechanisms to have that weight-loss conversation with their patients who need help.'
Lady Onslow added: 'Before, when I had to tell a patient they would benefit from losing weight, I felt they were judging me. I can now say I’ve been there and if I can do it so can you.'
She admits that at the beginning meal times required meticulous planning.
She now takes a balanced approach combining a calorie-controlled diet with regular activity.
The Rosemary Conley diet programme works with PCTs across the country and it is possible to get a referral on the NHS.
