Michael Phelps reveals how he managed 10,000 calories per day during his swimming career

Michael Phelps said eating became a 'full-time job' during that time in his life

Olympic swimming champion Missy Franklin talks Katie Ledecky’s dominance, leadership ahead of Summer Olympics

Five-time gold medalist Missy Franklin spoke with Fox News Digital about her expectations for Katie Ledecky ahead of the 2024 Summer Games next month in Paris.

Michael Phelps’ eating habits during his time competing are the stuff of legend at this point, and the all-time Olympics medal winner shared just how he was able to cram 10,000 calories in per day. 

The 39-year-old Phelps spoke with E! News at the premiere of his docuseries, "Fueled By," where he shared how his diet was while swimming, and what it’s like now that he’s not going against the best in the world in the pool. 

During his training days, Phelps would (somehow) consume 10,000 calories per day, and he revealed that junk food helped him hit that goal.

"I probably eat cleaner now than I used to," he said. "And that’s just because I’m not eating as much as I used to.

"There’s no way you can just eat clean and get all those calories. So, I was trying to cram ice cream and whatever I could into my system."

Eating junk food and not worrying about the repercussions sounds like a dream for most. However, Phelps viewed that 10,000-calorie-per-day system as a "full-time job for so long."

Phelps revealed in a 2021 interview with GQ that it was "challenging" to eat post-career, referencing the job aspect of consuming food, which went on well before he became a professional swimmer. 

Phelps also noted gaining "30 to 35 pounds" after retiring from the sport in that interview. 

Feeling like eating is a job is obviously not what you want each day. Now, things are much less relaxed and enjoyable for the 23-time gold medalist when he sits down for a meal.

"Now I kind of just eat what I need and what I want to — not just pretty much devouring everything in my sight," he said, via E! News.
