One of the "perks" of being an Olympic athlete is the free McDonald's in the Olympic Village - and some Olympians, who are some of the healthiest people on the planet, are consuming a stunning amount of french fries, McNuggets and Big Macs.

Australian badminton player Sawan Serasinghe failed to advance out of group play along with his partner Matthew Chau, but he's celebrated the end of years of hard work and intense training just to make the Olympic team by eating a McFeast.

Wow what a week it has been in Rio! Have to say I am disappointed about the match today. We definitely had a good chance...

"There are lots of good things to learn from the matches in the last three days playing against more experienced pairs. Can't wait to go back home to start training and keep on improving! Just want to say thanks again to everyone back home for the on going support. Definitely motivated me to fight hard on court everyday!

Now it's time to eat some junk food after months of eating clean."

Serasinghe isn't the only athlete binging on McDonald's.

Via the Washington Post:

"'The Chinese basketball team, they come all day, every day,' said one McDonald's employee, who was not allowed to give his name. 'The Chinese eat Big Macs at 9 a.m. It's crazy.'

So many people have been coming to McDonald's that the restaurant decided this week to limit to 20 the number of items that one person could order."
