In 2021, the I Am Jazz star shared that she gained "almost 100 lbs. in a little less than 2 years" amid her binge-eating disorder (BED).
She subsequently embarked on a weight loss journey, revealing that she lost 70 lbs. in January 2024. By August of that year, Jennings announced that she had shed 100 lbs.
"I still have room for improvement, but I am more motivated and inspired than I've been in years. Let's keep it going!"
she captioned a video montage of her working out from before and after her weight loss.
Most recently, on June 4, she posted selfies that showed off her dramatic transformation.
So how did Jazz Jennings lose weight? Here's everything she's said about her health journey.
In 2018, Jennings successfully underwent her first gender confirmation surgery. But ahead of the procedure, she lost 30 lbs. to get approved by her doctors for the operation.
"I really had to just retrain my mind. I had to look at food as something different than what I was looking at it as,"
she told PEOPLE in February 2019. "Because I used food as a comfort for my emotional struggles. I was a binge-eater. It was really bad."
Jennings explained that she had to "realize that was so unhealthy" and had to prioritize taking "care of myself."
She ultimately succeeded with her goal and even lost a "couple of extra pounds," she told PEOPLE in April 2018.
After her gender confirmation procedures, Jennings continued to struggle with binge-eating disorder (BED). In a 2020 episode of I Am Jazz, the transgender activist shared that she was trying to get healthy ahead of attending Harvard University, but was still dealing with her BED.
"I'm trying to get in the best shape of my life. I'm done caring about image. I'm beautiful no matter what size I am, but in terms of health, I'm not always very healthy,"
she said. “I fell off the wagon. got a chicken tender sub with buffalo sauce, five fried chicken drumsticks, a whole box of cookies,chocolate milk and Ferrero chocolates. It was a binge!”
At the time, Jazz’s mom, Jeanette, expressed concern for her daughter and said that she was unsure if Jazz would “fully get rid of binge-eating.”
“I’m really worried about her. There’s many times that Jazz has shown us that she has no impulse control,”
Jeanette said. “Now she’s going off to college, and I’ve always been around,[her father] Greg has always been around to help get her through those times that are really rough,and we’re not going to be there anymore.”
Jennings continued discussing her eating disorder in 2021, going into detail about her symptoms.
"I suffer from binge-eating disorder, a disease in which I'm not only addicted to food but I eat it in large quantities,"
Jennings said in a June 2021 Instagram post.
In 2021, Jennings shared that she gained a "substantial amount of weight."
In her Instagram post from June of that year, Jennings shared photos of her body before and after her weight gain, writing that she was prepared to "change my ways."
"My binging, along with an increased appetite I experience from some of the meds I'm on, has caused me to gain almost 100 lbs. in a little less than 2 years,"
she wrote. “I’m posting this photo because it’s time for me to address my weight gain and hold myself accountable.”
After prioritizing her health for years, Jennings announced in January 2024 that she had lost 70 lbs. In her post, the Florida native shared a photo of herself on the beach, expressing how she was feeling “happier and healthier” than ever.
“70 pounds down! Feeling happier and healthier than I’ve been in years,”
she wrote. “I still have a ways to go, but I’m so proud to finally be taking the necessary steps toward bettering my mind, body, and spirit💜💜💜.”
Four months later, she reflected on her journey and wrote about how she was “so proud” of her progress.
“Losing this weight and prioritizing my health has created a shift within,”
she explained in a June 2024 post. “The first step toward improving your well-being is caring. I finally care about myself after years of neglecting my health. I had truly let myself go when it came to eating. I am so proud of my weight loss, and I feel my confidence radiates through.”
By August 2024, Jennings announced that she achieved a major milestone, losing nearly 100 lbs. in two years.
“Two years later and almost 100 pounds lighter!”
she wrote. “I’m so proud of my progress and want to thank my family, friends and all who supported me in getting there! Good health is not a certificate you display; it is 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!”
Throughout her health journey, Jennings has posted about her various workouts and health regimens. She has led an active lifestyle over the last few years, including playing tennis and pickleball, running and swimming.
In addition, she's also credited her brother Sander Jennings for encouraging her and working out with her. In October 2024, she posted a video of them running together.
"My siblings have pushed me through my high highs and low lows. I can't thank them enough for always supporting me,"
she captioned the video. "Always support your loved ones dreams and tell them you believe in them."
Most recently, Jennings shocked her followers by posting a series of selfies showing off her weight loss.
On June 4, Jennings shared pictures of herself looking into the camera and posing with various faces. In the comments section, her followers applauded the progress she'd made.
"You should be very proud of yourself.❤️,"
one user commented.
"To look at someone's body and say this is not beautiful' is a reflection of social conditioning,"
she added. “You weren’t born saying that some bodies are not attractive. You were taught it. We all were. To distinguish one body as being ‘better’ is a societal construct of beauty standards. STOP JUDGING. WE ARE ALL BEAUTIFUL. EVERY BODY IS BEAUTIFUL.”
Later that same month, Jennings posted a photo of herself in a swimsuit, writing that “loving yourself and your body means honoring your desire to make a change.”
“How you look is important in this world because it influences how we perceive one another,”
she said. “Our bodies are our vessels,and everyone should have autonomy over how they treat theirs,whether it’s through diet,exercise,how we dress,makeup or surgery... Loving myself and my body means taking the steps and making the changes that help me feel my best and present myself authentically.”
