Melbourne players are stepping back more than 12,000 years in time as they look to turn their fortunes around in season 2015.
The Demons, including coach Paul Roos, have adopted the paleo diet which is commonly referred to as the 'caveman diet'.
It is a high-fat, low-carb approach to eating, which gets its name from the Paleolithic era many argue was when humans began eating new foods that the body can’t properly handle.
"We felt this was an opportunity for us to get a bit of a jump," Melbourne elite performance manager David Misson told the Herald Sun.
"More than anything, we wanted to put a discipline around their eating because the feeling was a lot of footballers eat for comfort rather than performance and we felt our guys could benefit from following a really strong and structured diet."
In its most strict form, Paleo prohibits the consumption of bread, pasta, wheat, oats and dairy products.
The Dees are allowed to eat rice and milk, but otherwise avoid processed foods and carbohydrates.
The AFL's best player, Gold Coast Suns captain Gary Ablett, follows the same diet, as does basketball superstar LeBron James and several NRL stars, including Manly's David 'wolfman' Williams.
Several of the Demons players have already stripped significant weight.
"There’s no doubt that’s been a by-product of it. That wasn’t the main intention because we were pretty comfortable where they were at, but the guys have definitely stripped some weight," Misson said.
"Dawesy (Chris Dawes) I haven’t seen look as good as he does since he’s been at Melbourne."
Despite showing early promise under Roos, Melbourne endured a year to forget in 2014 as they managed just four wins and finished the season second-last.
