Serena Williams‘ revelation on Thursday that she’d lost 31 pounds came with another confession: the tennis icon had used drug Zepbound, a GLP-1 medication, to shed the weight.

Of course, weight loss drugs have become popular in recent years, and GLP-1 – a natural hormone that helps regulate blood sugar and appetite – is also found in brands such as Ozempic, Wegovy and Mounjaro.

But fans were angered with Williams’ appearance discussing the drug on the ‘TODAY’ show. The tennis icon is a paid spokesperson for telehealth company Ro, through which she accessed the drug, while her husband, Reddit founder Alexis Ohanian, is also an investor and serves on the company’s board.

So when Williams spoke glowingly about taking the GLP-1 drug through Ro, fans questioned if the 23-time Grand Slam singles champion was acting ethically.

When reached for comment regarding whether Williams’ appearance on ‘TODAY’ was paid, a ro spokesperson referred the Daily Mail to a press release announcing Williams’ partnership with the brand.

‘I hope Ro is paying the @TODAYshow for this extended ad with serena Williams. I hate this kind of advertorial stuff cloaked as news,’ one person wrote on X.

The 23-time Grand Slam champion admitted that she has been using a weight loss drug.

Serena Williams Weight Loss Ad Faces criticism Online

Serena Williams’ recent partnership with a weight loss company is drawing notable criticism on social media. Many users are expressing disappointment and frustration, arguing that the ad undermines Williams’ legacy as a champion of body positivity and athletic achievement.

One commenter stated,”Seeing THE Serena Williams being used to sell weight loss products feels like an insult to everything Serena Williams represents,stands for,and has achieved,even if she herself or her team doesn’t feel that way.”

Another user wrote, “seeing serena williams, a whole gold medal olympian, be on a GLP-1 talking about how she “finally lost weight” just broke something in me.”

“Serena Williams doing ads for Ozempic?! The body positivity movement is officially dead.Men hate us so much, they aren’t satisfied unless we hate ourselves, too,” posted another, tho it’s important to note that Williams is actually promoting a different brand.

Williams recently shared photos of her new physique after workouts and discussed her weight loss journey with People and TODAY, revealing she lost 31 pounds using weight loss medication.
