Elon Musk has publicly credited his weight loss—about 30 lbs—with using GLP‑1 medications such as Wegovy (semaglutide 2.
What Musk Has Confirmed Publicly
In late 2022, Musk stated on X (Twitter) that he used Wegovy (semaglutide 2.4 mg weekly) plus intermittent fasting to lose weight.
By 2024, he also confirmed using Mounjaro (tirzepatide), another GLP‑1 medication.
He jokingly referred to himself as “Ozempic Santa”, acknowledging GLP‑1 use.
Estimated Weight Loss
Reports indicate Musk lost around 30 lbs over his transformation period.
How the Medications Work
Semaglutide (Wegovy/Ozempic)
FDA‑approved for chronic weight management (2021).
Clinical trials show ~15% average body‑weight reduction at 68 weeks.
Mechanism: reduces appetite, slows gastric emptying, regulates hunger hormones.
Tirzepatide (Mounjaro/Zepbound)
A newer GLP‑1/GIP dual agonist.
2026 trials show ~20% average weight loss, outperforming semaglutide.
Lifestyle Components Musk Mentioned
Intermittent fasting: Musk has said fasting is his primary behavioral tool.
Keeping tempting foods out of sight and general calorie reduction.
Exercise also contributed, according to later interviews.
Sustainability & Medical Context
Stopping GLP‑1 drugs often leads to weight regain, per STEP‑4 data.
Long‑term success typically requires continued medication plus lifestyle changes.
Common side effects include nausea, vomiting, and diarrhea.
Elon Musk’s weight loss is well‑documented and largely attributed to GLP‑1 medications (Wegovy and later Mounjaro) combined with intermittent fasting and healthier habits, aligning with clinical evidence showing significant weight‑loss potential from these treatments.
