Dr Kevin Fernando, a partner at the North Berwick Health Centre, took part in the show after his wife put him forward.
The programme, which was filmed in September, will see Dr Fernando cooking for three other contestants from Edinburgh and competing for a £1,000 prize.
Although he could not reveal details of who won or what he cooked, Dr Fernando described his menu as ‘quite ambitious'. But he added: 'I managed to pull it off.’
Dr Fernando said both his partners and patients had been extremely supportive of his decision to take part . ‘I had a chat with my colleagues about it and then I thought I’d give it a bash.
‘The patients are behind me 100%, it’s been great. Recently more have been calling reception asking when I'll be on,' he said.
Dr Fernando added that he considered the TV appearance carefully before agreeing to take part, to make sure it would not affect his standing as a GP. ‘I said to them that after my family my career is the most important thing to me,’ he said.
Watch Dr Fernando on 'Come Dine with Me' on Channel 4 on Sunday 3 February at 7pm.
