Musk posted a photo in a Santa suit to show his body transformation. He is posing with his hands on his hips wearing the suit and a white Santa beard. While Santa is known for his big round belly, it was nowhere to be seen on the tech CEO, who stood proudly in front of a decorated Christmas tree with presents underneath.

“Ozempic Santa,” he captioned the photo.

In afollow-up poston X, he joked, “Like Cocaine Bear, but Santa and Ozempic!,” before admitting inanother postthat it was “technically Mounjaro” that he was using. He added that it “doesn’t have the same ring to it.”

“High doses of Ozempic made me fart & burp like Barney from the Simpson’s," he wrote in response to one comment onX. “Mounjaro seems to have fewer side effects and be more effective.”

The tech CEO, who has said in the past that he “wouldn’t exercise at all” if he could, revealed in 2022 that he another drug for weight loss, Wegovy. He also shared in a previousX postthat he practicedintermittent fastingwhen asked his secret to looking “fit, ripped, and healthy.”

Musk, who President-electDonald Trumphas tapped to lead a new temporary agency known as the Department of Government Efficiency (DOGE), has previously shared his support for the use of GLP-1 drugs to assist with weight loss. Ozempic, Wegovy, Mounjaro and Zepbound all fall under this category.

“Nothing would do more to improve the health, lifespan and quality of life for Americans than making [GLP-1 drugs] super low cost to the public. Nothing else is even close,” Muskshared on Xearlier this month.

However, others, includingRobert F. Kennedy Jr., have voiced their opinion that it isn’t necessary, if proper meals are had. He said, perABC News, “The first line of response should be lifestyle, it should be eating well, making sure that you don’t get obese, and that those GLP drugs have a place.”
