He is very particular about what he eats and how he maintains his ridiculous physique.
Juve youngster Daouda Peeters gave a valuable insight into how Ronaldo stays at the top of his game - and it involves a lot of chicken.
"Cristiano wants to win always and everywhere. I went to the gym for a while and, of course, Cristiano was also there.
"I was impressed. Cristiano has the perfect body for a footballer. And although I am also quite muscular, that day I thought; there's still work to be done. But hey, he's been doing it maniacally for so many years."
It won't come as a surprise to anyone, including Coca-Cola, that the world's all time top goalscorer in men's football isn't a fan of the carbonated drink.
The five time Ballon d'Or winner caused controversy last summer during the Euros, when he refused to be sat alongside two bottles of the stuff.
It was during a press conference and the drink had pride of place as one of the major sponsors of UEFA's event, but Ronaldo moved them to the side.
Ronaldo eats up to six meals a day and avoids all carbonated drinks as well as alcohol.
"A good workout must be combined with a good diet," the former Manchester United man said per Goal. "I eat a high protein diet, with lots of wholegrain carbs, fruit and vegetables, and avoid sugary foods.
"Eat regularly. If you train regularly it's important to keep energy levels high to fuel your body for better performance.
"I sometimes eat up to six smaller meals a day to make sure I have enough energy to perform each session at top level."
Ronaldo continued: "Learn to train your mind as well as your body. Mental strength is just as important as physical strength and will help you achieve your goals.
"Be disciplined. Keeping yourself motivated and sticking to your routine is key. For me, there is no room for easing off so I have to be strict.
"Training and physical sessions are most important, but living a relaxed lifestyle helps you to be the best you can be, physically and mentally.
"I spend my free time with family and friends, which keeps me relaxed and in a positive mindset."
A new set of teammates could soon be getting used to Ronaldo's eating habits, if reports are to be believed, with the United forward reportedly unhappy with the lack of signings at Old Trafford.
Chelsea's new owner Todd Boehly is said to have held a meeting with the player's agent, Jorge Mendes, over a potential move to Stamford Bridge.
