- Serena Williams revealed her use of a weight-loss drug, Ro's GLP-1, after her second pregnancy.
- Fitness influencer Kheiston Boone criticized Williams for promoting the drug, calling her the "weight-loss injection girl."
- Williams is eligible to return to competitive tennis in February 2024 after entering the drug testing pool.
Last August, Serena Williams made a shocking revelation about her weight-loss journey. In an interview, the 23-time Grand Slam singles champion revealed that she has been using Ro’s GLP-1 drug to shed weight after struggles to get back in shape post her second pregnancy.
This did not go down well with not just the tennis world, but the sporting world in general. Also, in an advertisement in the recently concluded Super Bowl, Williams was shown promoting the drug. Now, fitness influencer Kheiston Boone has called out Williams for becoming the “face” of the medication.
Free Serena Williams from whatever 360 deal she’s in. I’m tired. For me, this has been a lesson on how some partnerships can derail the brand you spent decades, blood, sweat, and tears building and how strategic you have to be.
Kheiston Boone wrote on her Threads account
Many think Williams is not giving the right message to the fans, especially to the young girls who see her as their inspiration. Although many are concerned about the side effects of the drug.
She’s no longer known as the Serena Williams, the world-renowned champion, but as the weight loss injection girl. Yeah, no. Free her! I get that she’s an investor but I just don’t understand why she had to be the face of it. She’s too high up for this.
Kheiston Boone added
Williams called time on her career after losing the third-round match of the 2022 US Open. The last time Williams won a tour-level singles title was at the 2020 Auckland Open, where Jessica Pegula.
Jon Wertheim on Serena Williams’ possible comeback
Serena Williams neither agreed nor denied when asked whether she would be making a comeback to the tour. Williams is eligible to compete in WTA-sanctioned tournaments from February 22.

Retired players can only compete after they enter the International Tennis Integrity Agency’s (ITIA) drug testing pool six months before returning to the tour. And guess what? Williams’ name was on the list.
And if she ends up playing, which is the first tournament she will be competing in? Tennis journalist Jon Wertheim cited Novak Djokovic‘s example to explain why Williams can still compete before suggesting the tournament where he thinks she could play.
I’ve got to say, I think this is great. We learned our lesson from Lindsey Vonn to Novak. If Serena still thinks she’s got some juice that can be squeezed, go nuts. “It would be one of the great tennis stories of 2026. It certainly is looking that way, I’ve heard various things, this is more a mixed doubles, or a return to Wimbledon, where she did not like the savor of her last match there. I think it’s great.
Djokovic, at the age of 38, secured a stunning five-set win over two-time defending champion Jannik Sinner in the semifinals of the recently concluded Australian Open before he suffered a four-set defeat at the hands of Carlos Alcaraz in the final. Vonn, the legendary American alpine ski racer, 41, ended up damaging her left ACL in a downhill crash during the Alpine Ski World Cup.
At Wimbledon, Williams won seven singles titles, last winning in 2016. The last time she reached a Grand Slam final was at the 2019 US Open, where she lost to Bianca Andreescu. The same year, she also featured in her last Wimbledon final, where Simona Halep denied her the title.
The former World No.1, also the winner of 73 singles titles and 23 doubles titles, added 14 Grand Slam doubles titles to her trophy cabinet, winning all with her sister and seven-time Grand Slam singles champion Venus Williams.
