Serena Williams is one of the most successful athletes in history. With 23 Grand Slam titles and a reputation for being not only powerful but also relentless in her mindset, she has inspired millions far beyond tennis. Which is why her recent admission about using a GLP-1 weight loss medication has drawn so much attention.
According to reports, Serena first tried a GLP-1 treatment in the summer of 2024 but did not continue with it for long. She then resumed treatment in early 2025 through the telehealth company Ro, using the brand Zepbound. It was not until August 2025 that she spoke openly about her use of the medication and her partnership with Ro, describing how it had helped her feel physically and mentally lighter.
For a woman who has been under the spotlight for her body for her entire career, it is no surprise this has become such a talking point. The debate is not only about the drug itself but about what it means when one of the most disciplined athletes of all time decides medication is part of her journey.
Why This Is Different to a Celebrity Endorsement
When a singer or actor shares that they have used a GLP-1 injection, the reaction tends to focus on Hollywood pressures and image. Serena is different. She is an athlete who reached the very top of her sport, who knows more than most about nutrition, training and performance. If anyone would be expected to manage weight gain or post pregnancy changes without help, to many it would be her.
That is why her story carries weight. If someone with Serena’s background, discipline and knowledge admits that even she found it difficult, it challenges the stereotype that weight loss is always about trying harder.
What Serena Williams Said Herself
Serena has been clear that this was not a decision she took lightly. She spoke about questioning whether it might be a shortcut, about weighing up the pros and cons, and about doing her research before making the choice.
She has said that she was already exercising and eating well but that progress had stalled. The medication, in her words, enhanced what she was already doing rather than replacing it. She has also spoken about the relief in her joints and the ease of daily movement after losing weight.
The Positives of Her Openness
There are several positives that come from Serena’s decision to speak so openly.
- Reducing stigma. Weight struggles are often linked to willpower. By sharing her story, Serena shows that biology, hormones, age and post pregnancy changes all play a role.
- Adding to existing effort. Her message has not been one of instant transformation but of medication supporting an already disciplined lifestyle.
- Shining a light on reality. Athletes often appear untouchable. Serena’s openness makes her more relatable to anyone who has felt frustrated by slow progress despite effort.
- Highlighting mental as well as physical change. She has spoken not only about her body but about how she feels mentally, with improved confidence and energy.
The Concerns and Criticisms
There are still valid questions and criticisms, especially when an athlete of Serena’s stature takes this route:
- Some people see it as a shortcut, an easy way out, and worry it sends the wrong message. Serena herself said this was a concern she had before starting.
- Others argue that if an athlete with years of discipline and access to expert coaching chooses medication, it raises doubts about what ordinary people can achieve without it.
- GLP-1s are not risk free. They can cause side effects and need to be carefully supervised by medical professionals.
- Sustainable weight management and her long term relationship with food is also a question. What happens when treatment is reduced or stopped. Will the weight be maintained. The long term research is still developing.
- Finally, public pressure is intense. Serena has faced commentary on her body for her whole career. By speaking out she invites even more, which may be both brave and challenging.
What It Means Beyond Serena
Serena’s story does not mean that everyone should take GLP-1s, but it does show that different paths can work for different people. I work with clients who are using, or coming off, GLP-1 medication and I support them in building the right habits alongside it. Most of my clients can and do succeed without medication, relying on consistency, accountability and sustainable lifestyle changes. Whichever route you take, the foundations of progress are support, structure and habits that last.
Things to Keep in Mind
- Medical advice is essential. These medications are not suitable for everyone.
- Habits remain the foundation. Whether or not medication is used, long term success comes from daily behaviours.
- Cost and access can be barriers. Not everyone has the same resources.
- Long term sustainability matters. Whatever approach you choose, it should be one you can live with in the long run.
Is It a Good Look?
In my view, she did not frame it as magic or as an easy fix. She framed it as part of a wider journey, built on exercise, nutrition and research.
The real takeaway is that there is no single path. Serena’s choice does not diminish the hard graft of those who succeed through accountability and structure, nor does it invalidate those who find medical help makes the difference. Both approaches require effort. Both should be respected.
