We often associate professional athletes with a refined dietary regimen to keep their performance at the top level. Denver Nuggets center Nikola Jokic didn't exactly get that memo early in his career.

The 21-year-old Serbian international opened up about his propensity to drink a lot of Coca-Cola prior to being drafted by the Nuggets in 2014.

When asked how much of it he actually consumed, the 6-foot-10 big man wasn't shy about telling the truth.

“Maybe three liters or so. It was a lot,” Jokic told ESPN's Zach Lowe. “Never in the morning, because we had practices in the morning, and I could never drink before. But after practice, it was glass after glass. I couldn't stop.”

Asked if he still drinks coke, Jokic replied: “I haven't had any in the last one-and-a-half years. On my flight to come to Denver, I had my last Coke ever.”

Jokic kicked the habit with relative ease, he confirmed.

“It was easy. It felt really good, actually. It was good to know I didn't need it.”

A playmaking big that has now cemented himself as the team's starting center, Nikola Jokic is averaging 12.7 points, 7.8 rebounds and 3.7 assists for the Nuggets this season.
