Health and nutrition expert Dr Michael Mosley has explained how far you'd have to run to burn one single pound of fat.
Dr Mosley, the TV producer and presenter who is the creator of the 5:2 and Fast 800 diets, was exploring the theory that exercise will make you lose weight. Journalist Lydia Stephens tried the Fast 800 diet for a week and couldn't believe the results.
In an article on the Fast 800 website, Dr Mosley said it was a "diet myth" that exercise helps you lose weight, saying "that isn't what actually happens". He said: "It seems incredibly obvious. Do some exercise, burn some calories, lose weight. But that isn’t what actually happens. Part of the problem is that fat is very energy dense. You would need to run for about 36 miles to burn off a single lb of fat."
