UK man claims to have lost 7kg in a month eating only McDonald's

A UK postie and YouTuber who set out to disprove the results of famous documentary Supersize Me says he lost 7kg by eating only McDonald's for a month.

Ryan Williams, 29, launched his fast food mission at the beginning of October, in an effort to disprove Morgan Spurlock's famous documentary.

In 2004, the filmmaker became famous for gaining 12kg by eating McDonald's every day for 30 days, consuming over 5000 calories a day.

Williams documented his journey also eating McDonald's for a month, just as Spurlock did - but with a twist.

His problem with the original experiment was that Spurlock did no exercise, meaning his calorie intake wasn't offset. So Williams set his own challenge; working out for an hour each morning, spending between $27 and $36 per day on McDonald's and making sure to eat everything on their menu at least once, as Spurlock did 14 years ago.

Williams claims this one month diet and exercise programme dropped 7kg off his weight.

He says he started the month weighing around 90kg and finished up about 83kg.

Williams told The Sun that "prior to the challenge I was probably in the worst state I'd been in in a few years".

"My diet wasn't great, I would eat a lot of food - about 5000 calories - in a day, lots of biscuits and junk food, and I wasn't going to the gym at all," he said.

"Before that, for about 10 years, I was always very active and went to the gym four or five times a week.

"So for me, this challenge was partly about what I could do to help myself get back to that, whilst also having a bit of fun."

Meanwhile, Spurlock has been working on a sequel to his 2004 film, entitled Super Size Me 2: Holy Chicken!. It's said to explore the ways in which the fast food industry has rebranded itself as healthier over the last decade.
