Here’s the latest publicly reported information I can share:
Stephanie Buttermore, a fitness influencer and scientist, has been reported as having died at age 36 in early March 2026. Multiple outlets cited an announcement from her fiancé, Jeff Nippard, confirming her passing and asking for privacy.[1][2][8]
At the time of reporting, authorities or family had not disclosed an official cause of death publicly, and many articles note the lack of specifics beyond the notification of her passing.[2][5][1]
tributes and coverage continued through mid-March 2026, with emphasis on her work, mental health advocacy, and career in cancer research, as well as the impact she had on her audience.[5][2]
If you’d like, I can compile a short timeline of the major posts and statements from her fiancé and the outlets covering the news, or search for the latest official statements from Jeff Nippard or family when they become available. Please tell me which format you prefer (timeline, bullet summary, or a brief article).
