The music producer revealed that he took part in quite the diet experiment: only eating pizza for five days to see if he could lose weight.
As Blanco explained in an Aug. 19 TikTok, he decided to try it in an effort “to prove you can lose weight eating literally anything.” And indeed, he dropped nearly five pounds thanks to the cheesy meal plan.
The 38-year-old started the week weighing 152.2 pounds before digging into his pizza of choice: a large thin crust cheese pizza from Domino’s.
“This is 1/16 of everything I can eat today,” he mused while holding up a slice on day one, before sharing that things took a turn on day two. “Just came back into work and someone ate like eight slices of my pizza.”
Day two also included a visit to the Sunset Tower Hotel with wife Selena Gomez, who enjoyed her own meal from the Los Angeles hot spot while Blanco munched on his thin slice that he held under the table.
But even for a pizza lover, the experiment took its toll, with Blanco admitting on day three, “I'm tired of pizza. I hate my life.”
And on day five, he told the camera, “I don't even remember who I am as a human being. Like, what was life before pizza?”
Still, the constant pizza wasn’t that bad as he noted he was feeling, “f--king good” with a “spring in my step.”
As for how his experiment ended? Blanco’s final weigh-in revealed his weight to be 147.5 pounds.
“I just lost 4.7 pounds in five days eating only pizza,” he exclaimed. “Nothing matters. You can do whatever you want. F--k failure. F--k everything.”
Of course, Blanco is no stranger to a pizza party as he and Gomez celebrated her birthday in July with an Italian feast during a cooking class at Il Borro Relais & Châteaux in Tuscany where they made pasta, stuffed zucchini flowers and eggplant parmigiana.
“My baby makes the best eggplant parmigiana,” Blanco raved in a July Instagram video. “You scoop a little bit then you put it on a slice of bread. That’s the best thing I’ve tasted in Italy so far.”
Of course, the bonafide foodies have also documented their cooking adventures—like making watermelon pickle sandwiches—and even celebrated Valentine’s Day in a bathtub of nachos.
