Benny Blanco dropped 4.7 pounds after eating nothing but pizza for five straight days.
The music producer, 38, posted a TikTok video Thursday documenting the entire experiment, which he designed to prove you can lose weight “eating literally anything.” At the start of the clip, Blanco steps on a scale showing he weighs 152.2 pounds. He then commits to consuming only one large thin crust pizza from Domino’s per day for the full five days.
The footage follows him through the week, including one date night with wife Selena Gomez, 34, at the Sunset Tower Hotel in Los Angeles. While Gomez enjoyed the upscale restaurant’s food, Blanco pulled out his Domino’s pizza at the table. At one point in the video, the “Only Murders in the Building” star is seen kissing his neck.
By day three, the novelty had worn off completely. “I hate my life,” Blanco admitted in the footage.
“I don’t even remember myself as a human being,” he said on day five. “Like, what was life before pizza?”
Despite the misery, he insisted he felt “f–king good” by the final day.
When he stepped back on the scale at the end of the experiment, the number read 147.5 pounds. “I just lost 4.7 pounds eating pizza. Nothing matters, do whatever you want,” Blanco declared in the video, before pivoting to promote his upcoming book.
The book, titled “F–k Failure,” is scheduled for release Sept. 15 through Simon & Schuster. According to the publisher, it teaches readers how to achieve their dreams by making the most out of failure.
“You want success? You gotta fail better,” Blanco said. “I fail constantly — small everyday failures and massive failures that last for years. I’ve learned a few tricks along the way, and all of them have to do with turning f–king up into an artform.”
“My superpower as a producer is helping people tap into the success that’s already inside of them,” he added.
Blanco’s food obsession runs deep. He released his cookbook, “Open Wide: A Cookbook for Friends,” in April 2024, and has frequently showcased his elaborate home kitchen setup, including a bespoke Neapolitan pizza oven with his name tiled on the dome. His Hollywood Hills home also features a custom Santa Maria grill and a Big Green Egg.
The pizza experiment comes months after Blanco exposed Gomez’s own eating habits during a May appearance on Gwyneth Paltrow’s “Goop” podcast. He described the “Calm Down” singer’s diet as that of a “5-year-old,” built around fast food and snacks.
“This morning I walked in and she was eating Jack in the Box at 6:45 in the morning,” Blanco shared on the podcast, identifying her two favorites as “burgers and fries.”
He also noted that Gomez mainly prefers “whatever is bad for your diet,” and “doesn’t really like fruits or vegetables.”
Blanco and Gomez began dating in late 2023 and married in September 2025 at Sea Crest Nursery in Santa Barbara, California, before 170 guests including Taylor Swift, Ed Sheeran, and Gomez’s “Only Murders in the Building” co-stars Steve Martin and Martin Short. The couple first collaborated musically in 2015 when Blanco produced tracks on Gomez’s “Revival” album, and they released their joint album “I Said I Love You First” in March 2025.
Blanco’s upcoming book “F–k Failure” hits shelves Sept. 15.
