Jazz Jennings Has Had An Inspiring Weight Loss Transformation

Jazz Jennings was initially introduced to audiences during her appearance on "20/20" with Barbara Walters in 2007, when she shared her journey of being transgender as a child. This allowed for a deeper representation of those in the LGBTQ+ community in the media. Since then, Jennings has been known as an advocate for her community and media personality after starring in her own reality TV series, "I Am Jazz," which aired on TLC from 2015 to 2023. Her weight loss journey has been her latest focal point of advocacy and storytelling. 

In 2021, Jennings revealed on Instagram that she was experiencing binge-eating disorder (BED), which contributed to her drastic weight gain Binge-eating disorder is an illness marked by repeat periods of excessive eating, even after one feels full.Per The National Institute of Health, the condition impacts as many as 3% of the total U.S. population, making it one of the more prevalent eating disorders. It frequently causes people to gain weight or become obese.

"As many of you have noticed, over the past few years, I have gained a substantial amount of weight," Jennings revealed in the caption alongside a before-and-after photo. "I suffer from binge-eating disorder, a disease in which I'm not only addicted to food, but I eat it in large quantities. My binging, along with an increased appetite I experience from some of the meds I'm on, has caused me to gain almost 100 pounds in a little less than 2 years [...]." Watching Jennings' bodily transformation from then to now has been inspirational to many as she continues to hone her self-confidence. 

During Season 5 of her show "I Am Jazz", Jazz Jennings took viewers through her journey of undergoing gender confirmation surgery. Part of this included a mandatory weight loss. Per research published by Transgender Health, many doctors require a patient's BMI fall under 30 in order to have the procedure. In one episode of "I Am Jazz," Dr. Marci Bowers shared (via People), " Literally, they won't approve it if your BMI is one dot over." She elaborated that there were medical reasons for this, noting that "if there's more weight, it makes the surgery longer and it makes it more difficult." For Jennings, this meant she had to lose 30 pounds to be approved by doctors. 

Losing weigh wasn't easy. In an interview with People in 2019, she later explained that in order to lose the weight, she had to relearn certain eating habits. "I had to look at food as something different than what I was looking at it as because I used food as a comfort for my emotional struggles. I was a binge-eater. It was really bad. I would go to McDonald's, get 20 chicken nuggets, three chocolate chip cookies, and a large fries," Jennings expressed. This realization completely shifted her her approach to weight loss and relationship with food. Eventually, Jennings got the confirmation she needed and underwent a successful surgery, albeit with some complications.

While Jazz Jennings' surgery was successful (despite some complications), it didn't stop her experience with binge eating disorder (BED). In 2021, she shared on Instagram that after having the condition alongside the medication she'd been prescribed, caused her to gain almost 100 pounds in less than two years.

"I'm posting this photo because it's time for me to address my weight gain and hold myself accountable. I'm ready to change my ways; I've been saying I'm ready to turn over a new leaf, but I'm running out of trees now," she wrote in the caption. The star added that she was feeling extra motivated to start a new journey. "I'm ready to take the initiative and create positive changes when it comes to my health and body [...] I know I have the power in me to lose the weight, and I intend on sharing my progress with all of you. Love you all, and thanks for understanding the battle I'm fighting to win." Since making the post, Jennings started documenting her fitness journey publicly, sharing parts of her workout routine alongside her brother, Sander Jennings.

Three years after announcing her commitment to weight loss, Jazz Jennings posted a recap video on Instagram documenting her fitness journey. This clip showcased the hard work and dedication Jennings has put forth and the undeniable results she achieved through methods such as cardio and weight training. "Two years later and almost 100 pounds lighter! I'm so proud of my progress and want to thank my family, friends and all who supported me in getting there!" she wrote in the caption. It seems the experience has had a positive impact on Jennings' mental health, too. "Good health is not a certificate you display, it is a constant effort! I still have room for improvement, but I am more motivated and inspired than I've been in years. Let's keep it going."

Many of her followers took to the comments section to congratulate the star on her success. "You go girl! You look fantastic! Keep up the great work!" wrote one user, while another commented "Very proud of your strength to commit you looked great either way, now your just healthier." But it's not just Jennings' fans who have been supportive of her journey. A separate Instagram post showed the reality star running with her dad and being encouraged by him as she continued to push herself towards a new era. Another post features Jennings and her mom at the gym with the caption reading: "Teamwork make the dreamwork." 

Although Jazz Jennings isn't confirmed to be one of the celebrities who totally transformed after taking Ozempic or other GLP-1s, her weight loss has been equally as notable. During the summer 2025, she posted a photo dump of selfies on Instagram debuting her new look with a seemingly defined jawline and collarbone. Still, many in the comments section wondered how she achieved her results. One wrote, "Did she take GLP? Just wondering because she looks great," they wrote.

Jennings has not explicitly come out and denied GLP-1 use, though she has been adamant she achieved her weight loss through diet and exercise. Regardless, the star's weight loss has appeared to have a positive impact on her. Since 2026, the star has shared numerous photos on Instagram showing off her physique. Underneath one snap of her posing in an orange swimsuit, followers flocked to the comments to remark on how beautiful and happy the star appeared.

The Ozempic & other GLP-1 side effects that can make your beauty routine more expensive could be used as motivation to go a different route towards reaching one's weight loss goals. Paired with Jennings' weight loss efforts, it could be what helps people to take their health more seriously and follow in her footsteps of losing weight through diet and exercise for the sake of overall health and self-confidence.
