Fitness Influencer Stephanie Buttermore Dead at 36, Fiance Jeff Nippard Confirms

Fitness influencer Stephanie Buttermore has died. She was 36.

“It is with profound sorrow that we share the sudden passing of Jeff’s fiancée and partner of 10 years, Stephanie,” a Friday, March 6, Instagram statement from bodybuilder Jeff Nippard’s team read. “As many of you know, Stephanie meant the world to Jeff.”

The statement continued, “She will be remembered for her warmth and compassion, her love for her family and her Ph.D research on ovarian cancer. We kindly ask for privacy as we navigate this tragic loss. Thank you for your understanding and support during this difficult time.”

A cause of death has not been publicly revealed.

Buttermore was a social media personality with over 570,000 Instagram followers and 1 million YouTube subscribers, sharing fitness and nutritional uploads. She had taken a step back from social media in 2024.

“I’ve been pretty MIA on social media all year, but I’ve taken some pretty valuable things away from it,” Buttermore wrote via Instagram in May 2024. “My mental health has been the best it’s ever been, but I’ll give you some specifics. I no longer struggle with anxiety. At all. It was almost crippling a few years ago to the point I felt I couldn’t breathe or leave my house. Now, I really don’t have to care whether people liked what I posted or if they are saying negative things about me.”

Since taking a hiatus from Instagram, Buttermore learned to be “way more present” in her daily life.

“When you don’t even think about opening Instagram out of habit, it’s like finally opening your eyes to what’s going on around you,” she added at the time. “When I’m with my family or Jeff, I’m much more immersed in the moment. I take photos for the sake of saving memories and not because I’m going to post it on my Story. I never get caught not listening to someone because I’m checking comments, and I’m in a better mood because I’m not anxious. Family time is family time.”

At the same time, Buttermore missed interacting with her community of loyal followers.

“I miss my social media friends and community,” she noted. “So not only did I not post, I also didn’t consume any content on IG. I opened the app maybe once a month and tbh I genuinely missed seeing what my friends were up to. I miss the positive interactions I used to have in my DMs and in my comments. Of course social media can be toxic, but it can also be an amazing place to connect, learn, get motivated and make friends.”

Buttermore is survived by her family and Nippard, who proposed in 2022 after six years of dating.
