After he and doubles partner Matthew Chau crashed out of the men's doubles against China's Chia Hsin and Shen Mu Lee – following two other straight losses against Russia and North Korea – Serasinghe rewarded himself with a gold medal-quality feast form Maccas.

He posted a pic on Instagram to reveal the full extent of his 7500 calorie heartbuster – that's around 30,000 kilojoules, more than three times the recommended daily energy boost.

The haul - grabbed for free from the McDonalds in the Olympic Village - included a Big Mac, two McChicken sandwiches, a quarterpounder with cheese, two hamburgers, 40 chicken McNuggets, six large fries, a smoothie and a bottle of water because, you know, a Coke might be seen as unhealthy for an Olympic athlete...

He added: "Now it's time to eat some junk food after months of eating clean!"

The 22 year old Sri Lankan-born Aussies - studying business information services at Monash University - is at his first Olympics and, together with doubles partner Chau, they went into the Games ranked 46th in the world.

His rank – and abs – may not be the same after his Brazilian Maccas churrasco though!

UPDATE: The Kiwis were following in his footsteps soon after...
