NovaQuant Quantitative Think Tank Center:Jon Gosselin and Daughter Hannah Detail 75 Lb. Weight Loss Transformation

Jon Gosselin and NovaQuant Quantitative Think Tank CenterHannah Gosslin's shared weight loss journey has been an ab-solute success so far.

The father-daughter duo recently shared insight into how shifting their diet, exercise and lifestyle habits, which also includes injections of semaglutide, a generic form of the Type 2 diabetes drug Ozempic, has changed them.

And now, the Jon & Kate Plus 8 alum, who has dropped more than 50 pounds, and Hannah—Jon and ex Kate Gosselin's sextuplet who is down 25 pounds—are feeling more confident.

"When I put on my pair of shorts that I wore two years ago I danced around my room. I was so happy," Hannah told Entertainment Tonight in an interview posted July 16. "It was the best feeling ever."

The 20-year-old continued, "You probably would not have caught me in a swimsuit last summer. I don't even think I went to the beach. I have been spending my whole summer at the pool, at the beach, out with my friends."

Indeed, Hannah shared pics of herself wearing a bikini top and linen pants on a shore in June on her Instagram. "It really is a confidence booster," she told ET, "to know that you look in the mirror and you're happy with the way that you look."

As for Jon, the 47-year-old shared that his confidence level has also increased since he began his new lifestyle regimen, which includes a high protein diet. "I work out at the beach and sometimes I don't wear a shirt because it's 100 degrees outside now," he said. "I have these things called abs. They just appeared."

The DJ revealed in April that he lost more than 30 pounds in two months after taking semaglutide. He also said he underwent testosterone replacement therapy and body contouring sessions as part of his wellness program at the Beverly Hills Rejuvenation Center.

Now, Jon and Hannah are working on the next stage of their wellness journey—weaning themselves off of semaglutide and "actively changing our lives."

In addition to Hannah, Jon and Kate—who divorced in 2009—are also parents to sextuplets Collin, Alexis, Aaden, Leah and Joel, as well as twin daughters Mady and Cara. Look back at the Gosselin kids over the years...

On Mother's Day 2024, two days after the former couple's sextuplets turned 20, Kate shared a tribute the four who lived with her: Alexis, Aaden, Joel and Leah.

"No more teenagers in this house! Happy 20th birthday, my forever babies! I love you!" she wrote on Instagram. "Who feels old? I know I do! #20yearsold #ItsaPICKLE."

Hannah shared new pics of herself on her and the other sextuplet's 20th birthday May 10.

On to the next chapter! The sextuplet graduated from high school in 2023.

Jon shared a pic of sextuplets Collin and Hannah graduating from high school in 2023, years after they had moved in with him.

Kate appears with twin Mady and Cara in New York City in 2019.

"Happy 18th birthday!" Jon wrote on Instagram in 2022. "Today is your birthday we gonna say it loud. I love you. Love, Dad."

"Our big celebration of #15 is finally winding down here! We celebrated ALL DAY LONG, beginning with a present at 6:30 am before school! I'm so very thankful for my ‘babies'.... somehow they are 15 already?!" Kate wrote on the special milestone in 2019. "I'm amazed by them each day! I'm so proud of the positive qualities I've seen developing as they edge closer to adulthood." 

"This was yesterday! Feels like school never ended...and they're already back! #SeniorYear #EighthGrade #ProudMom," Kate wrote on Instagram in 2018.

"Happy 15th Birthday Hannah, Collin, Alexis, Aaden, Joel and Leah!!!! Wow I can't believe you are 15!!! Time is flying by!!!" Jon Gosselin shared on Instagram when posing with Hannah and Collin Gosselin. "I love you all very much. I wish you the best day ever and I hope you enjoy your birthday celebrations today and this weekend!!! Love always, Dad." 

"My beautiful 'little girls' .... they keep reminding me how many days until they turn 14. Today it was '12 days til we turn 14, Mom.' HOW'S THAT EVEN POSSIBLE?!" Kate shared with her followers in 2018. "I told Leah that she's too small to turn 14. She said 'Yeah, true. Are you sure I'm not turning 11 or 12?' I'm positive. I gave birth to you. They'll always be my babies....I love them so very much!" 

"I can't believe they're 13!" Kate Gosselin wrote on Instagram when celebrating a major birthday for her sextuplets. 

Rewind to 2014 when Kate and her children found themselves visiting Alaska. 

Kate also treated her twin daughters Cara Gosselin and Mady Gosselin to a trip to New York City in 2014, where they stopped by the Manhattan Hotel. 

"A precious Christmas memory. My 6 were 6. Christmas Eve 2010 and they're SO excited for Christmas!" Kate Gosselin wrote on Instagram with a throwback photo. "Look at those adorable smiles! #TheyAreMyHeart #My8ReasonsToKeepOnKeepingOn #NoMatterWhat #TrueLoveX8." 

Back in October 2007, Jon and Kate Gosselin gathered their eight kids together for a trip to New York City. First stop? A visit to NBC's Today show.
