The fitness community is mourning the sudden loss of Dr. Stephanie Buttermore, a popular influencer and dedicated cancer researcher, who passed away at the age of 36. Her fiancé, Jeff Nippard, announced the tragic news on Friday, leaving fans and fellow creators in shock.
Nippard’s team shared the announcement via Instagram and YouTube, expressing “profound sorrow” over Buttermore’s unexpected death. The statement highlighted Buttermore’s warmth, compassion, and commitment to her PhD research focused on ovarian cancer. While the cause of death has not been publicly released, Nippard’s team requested privacy during this tough time.
Buttermore and Nippard shared a decade-long relationship, becoming engaged in 2022. The couple frequently collaborated on content, blending fitness expertise with scientific rigor. Nippard recently posted a photo of the two of them on Valentine’s Day, captioning it “Relationshipmaxxing with tea time to lower cortisol levels,” a testament to their shared focus on wellness.

Beyond her influence in the fitness world, Buttermore was a respected academic. She earned a PhD in pathology and cell biology, specializing in the molecular mechanisms driving ovarian cancer progression. Her research focused on identifying proteins used in early-detection urinary screenings, demonstrating a dedication to advancing cancer research. According to her YouTube channel, Buttermore’s work aimed to improve early detection and treatment of this challenging disease.
Buttermore gained a significant following on social media, amassing over 500,000 Instagram followers and over 1 million YouTube subscribers. She shared workout videos, body-positive content, and personal insights, often incorporating her scientific background into her advice. She was known for her “All In” challenge, where she ate upward of 10,000 calories per day to promote healthy weight gain and body positivity for women.
In a surprising move, Buttermore stepped back from social media in May 2024, citing a significant improvement in her mental health. In a final Instagram post, she explained that she no longer struggled with anxiety, a condition that had previously been debilitating. “I really don’t have to care whether people liked what I posted or if they are saying negative things about me…,” she shared, highlighting the positive impact of prioritizing her well-being.
Nippard, a Canadian drug-free powerlifting and bodybuilding champion with over 8 million YouTube subscribers, has built a platform focused on science-based lifting information. His recent video addressed body dysmorphia, a topic that underscores the couple’s commitment to promoting healthy relationships with fitness and body image.
Following the announcement, an outpouring of support flooded social media. Fellow influencer Buff Bunny posted on Nippard’s Valentine’s Day photo, writing, “Heaven gained an amazing angel. Someone who cared so deeply for others. Praying for you Jeff and her family.” Numerous fans echoed these sentiments, expressing their condolences and admiration for Buttermore’s impact.
As the fitness community mourns this loss, the focus remains on supporting Jeff Nippard and honoring Stephanie Buttermore’s legacy of dedication to both health and scientific advancement. The circumstances surrounding her death remain private at the request of her family and fiancé. Further details will be shared as they become available.
