He currently has 20 Grand Slam titles on his record and will compete in the clay season so he can attempt to win a 21st at the 2019 French Open in Roland Garros. He will also be one of the favorites at the Wimbledon Championships in the summer.
Even at 37, Federer continues to marvel on the courts. But to maintain his sporting dominance, he has to eat right. So what sort of food does the face of tennis eat?
Here's everything Federer likes to have for breakfast, lunch, and dinner.
This is 20-time Grand Slam champion Roger Federer, who is widely considered as the best male tennis player of all time.
To start his day, Federer prefers to go sweet rather than savoury and reportedly enjoys homemade waffles with a fresh fruit compote on the morning of a match.
To wash the waffles down, Federer has fresh juice, coffee, and a vinegar shot.
Before tennis, Federer will eat a plate of pasta. "Two hours before every match, I eat pasta with light sauce I have been doing it for 20 years."
In between practice sessions or competition matches, Federer is no stranger to snack bars.
He also eats bananas, which are a good source of carbohydrate and potassium. When tennis players contest long matches, their energy levels may lull and they may succumb to cramp if they lose too much potassium. Bananas help players like Federer refuel.
However, research suggests that energy drinks may be a superior way of replenishing an athletes body during competition. This is because the body absorbs liquids quicker than solid foods, like a banana.
When Federer goes out for dinner, variety is clearly the spice of life. "I am a lover of Italian, Japanese, and Indian restaurants," he said recently.
He even likes to take selfies with his naan bread.
Its not all health foods, though. Federer does have a sweet tooth and cant resist ice cream. "I like my ice cream, I like my chocolate," he said in 2017. "Thats my diet. I like my treats. I dont feel bad about it. I can do it and play tennis at the same time."
Being Swiss, he is no stranger to cheeses and likes to eat fonduta, a dish that combines milk, cream, cheese, and egg yolk. He also has raclette (pictured), a cheese thats melted and scraped onto a plate.
Federer has also tried local delicacies in other countries, including Scotland. He once received Irn-Bru and a tin of shortbread biscuits made especially by Andy Murrays grandmother.
One thing Federer doesnt eat is wombat meat. It was an allegation he denied during a bizarre interview conducted by Will Ferrell, who channeled Ron Bergundy, his character in the hit comedy movie "Anchorman," at the 2018 Australian Open.
Federer drinks alcohol if he is celebrating success. He may look dapper here in his tuxedo and his glass of champagne, but sometimes he doesnt just have one glass and suffered a "head-ringing" hangover when he mixed his drinks until 5 a.m., the morning after his eighth Wimbledon title, in 2017.
Sometimes theres not a trophy big enough for Federers champagne diet ...
But that doesnt seem to be holding him back.
