“It's amazing how he's survived this long.” Those were the words of a nutritionist when discussing Keith Sorrell. She said this because the 37-year-old British man has been eating nothing but Mars chocolate bars for 17 years. The man says: “I can easily polish off 12 a day, more at weekends. I'm totally addicted.” He goes on to explain: “My love of Mars Bars started at school with one or two between meals. All my pocket money went on them and one day I realized I couldn't get by without them.” Vitamins and orange juice are the only other things that he takes in and experts warn that he's not getting enough fiber and this could cause serious health risks. Reportedly, he has no plans to change his diet.
