Elon Musk got into the holiday spirit by dressing up as Old Saint Nick in a photo that showed off his slimmed down figure.

Musk, 53, posted the snap on his social network X, formerly known as Twitter, on Christmas Day, Dec. 25, with the caption “Ozempic Santa.”

He noted that the correct drug mentioned should “technically” be Mounjaro, “but it doesn’t have the same ring”. He then joked that his odd costume combination was “Like a Cocaine Teddy Bear, but Santa and Ozempic!”

Musk also shared why he prefers Mounjaro: “High doses of Ozempic made me fart and burp like Barney from The Simpsons,” he wrote. “Mounjaro seems to have fewer side effects and is more effective.”

The billionaire was a proponent of GLP-1 drugs. Originally designed to treat type 2 diabetes, these drugs have become a popular weight loss tool because they help regulate blood sugar and appetite.

“Nothing would do more to improve the health, longevity and quality of life of Americans than manufacturing [GLP-1 drugs] super low cost to the public. Nothing else is even close,” the co-head of Donald Trump’s newly created Department of Government Efficiency wrote on X on Wednesday, December 11. Musk added: “A lot of people are going to complain about this post, but I’m right.”

The Tesla founder joins a growing list of famous people who have used GLP-1 drugs to lose weight.

“I know a lot of people take Ozempic and that’s totally fine. To each their own,” said the 35-year-old. Pretty Little Liars the actress wrote on Instagram in June that she slimmed down after giving birth to her baby girl last winter. “But don’t discredit people who are also working very hard to get their bodies back like I did with mine… Going back to work made me focus on my health and exercise and I wanted to feel confident and good.” I.”
