Cooper, who is now contracted to Japanese club Kintetsu Liners, said he and good friend Williams have spent the last eight months avoiding vegetables, fruits and carbohydrates because they are trying a diet that better suits their requirements.
And Cooper, who previously represented the Melbourne Rebels and the Reds in Super Rugby, reckons he’s in the best shape of his life.
The 32-year-old told the Daily Telegraph he wouldn't recommend the diet for everyone, but believes it’s doing the trick for him as he prepares for another season playing rugby in Japan.
"I'm no expert in this field, this is my science, it's what works for me," Cooper said.
"Others might try it and say, 'It's not for me'.
While Cooper is contracted to play in Japan, Williams is locked into a deal with Canadian rugby league club the Toronto Wolfpack.
Both men are renowned for their work ethic in the gym, and Cooper often posts photos of his trim physique on social media.
Quade Cooper's daily menu:
07:00 - Bulletproof coffee (2 cups of coffee, 2 tablespoons of butter, 1 tablespoon of MCT oil)
09:00 - Sip bone broth throughout workout
10:30 - Two rib-eye steaks with salt and butter
18:00 - 800g tomahawk steak with roasted bone marrow and a dozen oysters
