Benny Blanco reveals weight loss from eating only pizza for 5 days

Benny Blanco says he lost 4.7 pounds after eating only pizza for five days

Music producer Benny Blanco has shared an unusual weight loss experiment on TikTok, documenting five days of eating only pizza to test whether he could lose weight while doing so. At the end of the experiment, he reported losing 4.7 pounds.

Blanco, 38, started the challenge weighing 152.2 poundsches, per the video he shared. Each day, he ate a large thin-crust pizza from Domino's, as reported by Page Six. The experiment was framed as an attempt to "prove you can lose weight eating literally anything," a goal he stated in the video, according to LADbible.

Throughout the five days, Blanco shared his reactions. By the third day, he said, "I hate my life," as quoted by multiple outlets. On day five, he remarked, "I don't even remember who I am as a human being," before adding that he felt "good" with a "spring in my step," according to Page Six.

At the final weigh-in, Blanco weighed 147.5 pounds, a loss of 4.7 pounds. He celebrated the result in the video, saying, "I just lost 4.7 pounds in five days, eating only pizza. Nothing matters, you can do anything you want." This quote was reported by LADbible, Page Six, and other outlets.

Blanco did not share whether he engaged in any additional activities during the experiment that might have contributed to the weight change, as Us Weekly noted. Health experts generally recommend a balanced diet and regular exercise for sustainable weight loss, though Blanco's video did not include such advice.

A cameo from Selena Gomez

The video also included appearances by Blanco's wife, Selena Gomez. In one clip, Gomez is seen embracing Blanco, and in another, she is shown eating a meal at a restaurant while Blanco ate his pizza, according to Page Six.

The couple, who were married in September 2025 according to Us Weekly, have been together since 2024. Gomez has previously spoken about her own health struggles, including past hospitalizations related to poor eating habits, as noted by The News International.

Promoting the book

Blanco used the video's conclusion to promote his upcoming book, "F* Failure," which is set to be released on September 15 by publisher Simon & Schuster. According to the publisher, the book teaches readers about resilience and overcoming setbacks, as reported by Page Six.

This is not Blanco's first foray into publishing. He released his first book, "Open Wide: A Cookbook for Friends," in 2024, according to Us Weekly. Blanco is also known for cooking for his wife, Gomez, and has spoken about their relationship in various interviews.

Reactions and context

Social media users commented on the experiment, with some noting that a calorie deficit—not the specific food choice—likely explains the weight loss, as LADbible reported. Doctors generally recommend a balanced diet and regular exercise for sustainable weight management, a point highlighted by Us Weekly.

Blanco's experiment comes amid other personal milestones. He and Gomez recently spent time apart while she filmed a new season of "Only Murders in the Building" in London, and they reunited for Taylor Swift's wedding earlier this summer, according to The News International. Blanco also traveled abroad to celebrate Gomez's birthday despite his fear of flying, the outlet added.
