She confirmed utilizing prescription medication to break a plateau that intensive training failed to resolve. While Williams has offered unusual transparency regarding her pharmacological regimen, specific numerical data regarding her absolute weight—both current and historical—remains largely undisclosed, complicating efforts to verify the metrics that defined her playing career versus her post-professional physique.
Verified measurements, journalistic estimates, and speculative figures have circulated since her transition away from competitive tennis. Primary source interviews and medical partnership disclosures help establish a factual baseline.
What is Serena Williams’ Weight and Height?
Media estimates consistently place Williams at 5 feet 9 inches tall throughout her career, though official tour biometrics remain unpublished. Her August 2025 announcement confirmed the 31-pound reduction achieved over approximately eight months, yet the absence of a baseline figure prevents calculation of her current absolute weight.
- Confirmed Reduction: 31 pounds lost between January and August 2025
- Height Consistency: 5’9″ cited across fan analyses and media estimates
- Pharmacological Method: Zepbound (tirzepatide) via telehealth platform Ro
- Timeline: Treatment resumed January 2025 after initial summer 2024 discontinuation
- Physical Context: Postpartum plateau following second child’s birth in 2023
- Exercise Component: Approximately 30,000 daily steps during treatment period
| Period | Weight Status | Height (Reported) | Verification Level |
|---|---|---|---|
| Career Prime (2000-2020) | ~155 lbs (estimated) | 5’9″ | Fan/Analyst calculations |
| Late Career (2019) | Unspecified | 5’9″ | No tournament records |
| Retirement (2022) | Transition phase | 5’9″ | Post-professional |
| Postpartum Peak (2023-2024) | Pre-loss +31 lbs | 5’9″ | Calculated from confirmed loss |
| Summer 2024 | Initial GLP-1 start | 5’9″ | Prior to discontinuation |
| January 2025 | Ro program initiation | 5’9″ | Treatment resumed |
| August 2025 | -31 lbs confirmed | 5’9″ | Primary source interviews |
How Much Weight Has Serena Williams Lost Recently?
Williams has definitively confirmed losing 31 pounds as of August 2025, though some sources cite a total of 34 pounds when accounting for fluctuations over the full year. The loss materialized after she began treatment with Zepbound, a dual GIP and GLP-1 receptor agonist, following the birth of her second child in 2023.
Williams specifically utilized Zepbound (tirzepatide), which targets both GLP-1 and GIP receptors, rather than Ozempic (semaglutide). Clinical trials indicate tirzepatide produces approximately 20.2% body weight reduction over 72 weeks compared to 13.7% for semaglutide.
The Postpartum Plateau
Following her second child’s arrival in 2023, Williams experienced initial rapid weight reduction common in postpartum periods, but subsequently encountered a stubborn plateau. She trained for hours daily without success, describing the struggle as “the one opponent she couldn’t defeat.”
Treatment Protocol and Exercise
Beyond pharmaceutical intervention, Williams incorporated dietary modifications emphasizing protein sources such as beans while maintaining rigorous activity levels including approximately 30,000 steps daily. This multifaceted approach distinguishes her results from medication-only protocols.
Did Serena Williams Use Ozempic for Weight Loss?
Contrary to widespread speculation involving Ozempic, Williams utilized Zepbound (tirzepatide) manufactured by Eli Lilly. She accessed the medication through Ro, a telehealth platform specializing in obesity treatment, where she resumed therapy in January 2025 after discontinuing an earlier unspecified GLP-1 prescription from summer 2024.
Williams obtained her prescription through Ro, a company where Serena Williams Husband Alexis Ohanian Updated Profile holds an investment position. She has since entered a formal partnership with the platform as a spokesperson.
Pharmacological Differences
Zepbound functions as a dual agonist targeting glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptors, whereas Ozempic exclusively targets GLP-1. Ro’s treatment protocols include both options alongside Wegovy and Saxenda, paired with lifestyle modifications for average reductions of 14-20% body weight annually.
Side Effect Profiles
Clinical literature associates GLP-1 medications with gastrointestinal effects including nausea, while warning against use in patients with family histories of medullary thyroid carcinoma (MTC) or Multiple Endocrine Neoplasia syndrome type 2 (MEN 2).
What Was Serena Williams’ Weight in Her Prime?
During her competitive years, analytical estimates derived from visual assessment and athletic build calculations placed Williams at approximately 155 pounds, though no official WTA or tournament records confirm this figure. Her muscular composition and Serena Williams Ass Bold Insights and Verified Facts regarding her powerful physique supported a higher lean mass than many peers.
No verified pre- or post-loss weight figures appear in primary sources, including television interviews or magazine exclusives. The 155-pound prime estimate and 5’9″ height represent analytical approximations rather than measured data.
Williams retired from professional competition following the 2022 US Open, concluding a 27-year career. The metabolic demands of elite tennis—requiring explosive power and extended cardiovascular endurance—supported a different body composition than her current post-retirement physiology.
How Has Serena Williams’s Weight Changed Over Time?
- Competitive Career (1995-2022): Estimated 155 lbs at 5’9″; peak athletic conditioning with significant muscle mass
- Retirement (September 2022): Transition away from professional training regimens; metabolic adjustment period
- Second Pregnancy (2023): Birth of second child; initial rapid postpartum loss followed by sustained retention
- Summer 2024: Initial GLP-1 prescription via alternate provider; brief discontinuation due to unspecified factors
- January 2025: Treatment resumed via Ro platform with Zepbound (tirzepatide); dietary modifications implemented
- August 2025: 31-pound loss confirmed; partnership with Ro announced; reports cite improved joint mobility and energy
What is Established Versus Uncertain About Her Current Stats?
| Established Information | Uncertain or Unverified |
|---|---|
| 31-pound loss confirmed (August 2025) | Exact current weight (lbs not disclosed) |
| Height: 5 feet 9 inches (consistently reported) | Official pre-loss baseline weight |
| Medication: Zepbound (tirzepatide) | Specific 2019 tournament weight |
| 8-12 month treatment duration | Whether Ozempic was ever utilized |
| Postpartum context (2023 birth) | Precise muscle mass percentage changes |
| Ro telehealth partnership | Long-term maintenance projections |
How Does Her Current Physique Compare to Career Demands?
Williams’s 31-pound reduction represents a significant percentage change from her estimated playing weight, potentially affecting the power-to-weight ratio that characterized her dominant serve-and-volley style. During competition, she maintained the physical capacity to train for hours daily; post-retirement attempts to replicate this intensity without pharmaceutical assistance failed to produce the desired metabolic results.
The shift from professional athletic maintenance to post-career weight management illustrates broader physiological transitions affecting retired athletes. Whereas competitive training naturally regulated body composition through caloric expenditure, retirement necessitated alternative interventions for Williams to achieve similar outcomes.
Her reported improvements in joint mobility and energy levels following the loss suggest functional benefits beyond aesthetic considerations, though medical experts emphasize that GLP-1 medications work optimally alongside resistance training to preserve lean muscle mass.

What Do These Updates Reveal About Her Current Status?
Williams maintains a height of 5 feet 9 inches while having reduced her body mass by 31 confirmed pounds through Zepbound-assisted treatment combined with substantial physical activity and dietary modifications. The retired champion continues to navigate the transition from elite athletic physiology to post-professional metabolic maintenance, having retired from tennis competition in 2022 after securing 23 Grand Slam titles.
