- 23 Grand Slam singles titles
- 4 Olympic gold medals
- One of only four players to spend 319 weeks ranked No. 1 by the Women’s Tennis Association
Her accolades speak for themselves. Serena Williams is more than a tennis champion—she’s a global icon with two decades of dominance on the court. Hashtag activists, reporters, and even her fiercest critics have elevated her into the rarefied air of G.O.A.T. status. She has redefined greatness not only in tennis but in her approach to life. In her own words from Queen of the Court:
“Hold serve, hold serve…focus, focus, be confident, hold serve, move up, attack, kill, smile, hold.”
Yet even for one of the most disciplined athletes in history, one arena has presented unique challenges: weight management. Serena recently revealed that she turned to a GLP-1 medication—specifically Zepbound—and lost 31 pounds in just eight months, a story that has captured headlines nationwide.
The GLP-1 Boom
She is not alone in this pursuit. Other celebrities have also turned to GLP-1 injections in search of change. In an interview with Essence, Serena admitted:
“I literally tried everything. Running, walking, biking, stair climbing. You name it, I tried it.”
Millions of dieters relate to Serena’s sense of exhaustion. Though most of us haven’t trained like professional athletes, many have tried endless diets, programs, and promises, only to watch the pounds inevitably return. The weight-loss industry has long sold quick fixes and “diet du jour” trends; yet the 90% failure rate of weight-control therapies persists.
Today, drugs like Ozempic and Zepbound have entered household vocabulary, mentioned alongside Aleve, Ibuprofen, Aspirin, and NyQuil. Prescriptions, hailed by many as “miracle drugs”, are skyrocketing.
The numbers tell the story:
- More than 2% of Americans are currently using GLP-1 drugs for weight management.
- Usage is up nearly 600% in just six years (Axios).
Physicians and researchers agree that GLP-1s can be highly effective. Paired with endorsements from icons like Serena, their appeal is undeniable. But here’s the truth – while injections can help you shed pounds, they don’t erase the cravings, vulnerabilities, or habits that caused weight gain in the first place. No injection can change the thinking and habits built over a lifetime. Weight isn’t the problem—it’s a symptom.
Food History: Why the Past Matters
Every person carries a food history—a lifetime record of habits, family influences, emotional triggers, and cultural traditions around eating. Food history explains why:
- Some people reach for sweets when stressed.
- Others can’t resist nighttime snacking.
- Many struggle at social events where food equals connection.
Unless you recognize and rewrite your food history, weight loss will always be temporary. GLP-1s may reset appetite – but, without addressing food history, old patterns creep back the moment the injections stop
What Is Behavioral Nutrition?
This is where Behavioral Nutrition steps in. It’s the emerging science that asks not just what we eat, but why, when, and how. Drawing from psychology, neuroscience, nutrition, and behavioral economics, it provides practical tools to transform eating patterns.
Key principles include:
- Anticipating scenarios: Prepare for weekends, vacations, and late nights before they sabotage you.
- Boxing in trigger foods: Don’t bring home the dessert you can’t resist. Buy one portion, not a dozen.
- Shaping environments: Create a kitchen, office, and routine that makes success automatic.
- Strategy over willpower: Backed by Nobel Prize–recognized principles, it shifts the focus away from “trying harder” toward playing smarter.
In short: diets and injections can be simply words on a page. Behavioral Nutrition is action for change.
The Critical Role of a Coach
Every champion of has a coach and the field of weight loss is no exception. Serena didn’t win 23 Grand Slams without guidance, feedback, and correction. As her longtime coach Patrick Mouratoglou once said:
“Even the greatest players need someone to see what they can’t.”
The same is true for eating behavior. On your own, a slip can spiral into guilt and relapse. With a coach, it becomes error correction—a chance to reset, learn, and return stronger. That’s the difference between yo-yo dieting and sustainable success.
Serena’s Lesson, Our Next Step
Salute Serena for her openness. By sharing her story, she reminds us that even the strongest athletes sometimes need support. But her journey underscores the bigger message: medication can start the process, but only habits and strategy can sustain it.
Many people do not want to stay on injections for a lifetime. Others may use them as a starting point. Some may prefer an entirely different route. No matter what approach you choose—GLP-1s, a structured program, or lifestyle change—you need strategy to navigate the journey.
