A McDonald's lover 'turned grey' when he gave up fast-food - and it emerged he had a rare condition that turned the sugar in meals into alcohol.
Gregory Cole, 58, admits that he loved a McDonald's burger and would eat them at every opportunity, but it turned out the high sugar content in the food was very bad for him.
One day he suffered a herniated disk and was told by doctors he would have to lose weight, but then he seemed to get sicker as he dieted - and he said his skin changed colour.
