The online fitness world is mourning Dr. Stephanie Buttermore. The scientist and beloved influencer died at just 36 years old, a devastating loss confirmed by her longtime fiancé, Canadian bodybuilder Jeff Nippard, on March 6.
While her official cause of death hasn't been revealed, the news has brought attention to Buttermore's final days in the public eye. Back in May 2024, she quietly stepped away from her fame to focus entirely on her mental health.
