Livelong Media has named exercise physiologist and nutrition scientist Dr. Stacy Sims as chief science advisor, adding a specialist in female physiology to guide the scientific direction of its women’s health content and growing live events business.
Sims joined the company effective July 31 and will serve as an independent advisor. Her responsibilities include reviewing the scientific accuracy of Livelong’s programming, advising on speaker selection and contributing to content surrounding the company’s events.
She will also take an on-stage role in Livelong’s summit series, delivering keynote presentations and moderating panels. Her first appearance in the new capacity will come at the Livelong Women’s Health Summit, scheduled for Sept. 25-26 at the Hilton Midtown in New York City.
Additional Livelong summits are planned for Dallas, Boston, San Francisco and New York in 2027, extending Sims’ advisory role across a broader national events platform.
The appointment gives Livelong a recognizable scientific voice as it seeks to differentiate its health coverage in a market where consumer interest in women-specific research, longevity and personalized health information has expanded. For media businesses operating in the category, scientific credibility has become an important point of distinction as audiences navigate a mix of clinical research, wellness content and commercially driven health claims.
Sims has spent more than two decades studying differences between female and male physiology in areas including exercise, nutrition and recovery. Her work has focused in part on challenging research and training approaches that treat male physiology as the default for women.
That research formed the foundation for her bestselling books “ROAR” and “Next Level.” Sims has held research positions at Stanford University and AUT University’s Sport Performance Research Institute New Zealand and has published research in peer-reviewed journals.
“I’ve spent my career challenging the notion that women’s health is just a smaller version of men’s health,” Sims said. She said Livelong’s emphasis on research rather than wellness trends attracted her to the platform and that she intends to bring the same standard to its events.
Her addition also reflects the increasing convergence of health media, expert-led education and live events. Rather than limiting Sims’ involvement to editorial review, Livelong is incorporating her expertise across programming, speaker curation and in-person experiences, creating a more integrated scientific framework for its content.
Founder Brad Inman said Sims’ track record of challenging conventional approaches to women’s health aligns with Livelong’s focus on providing scientifically grounded information.
“Having her guide the scientific direction of our work means our audience gets exactly what we promised them from the start: scientific information they can actually trust,” Inman said.
For Livelong, the appointment comes as it develops its position within the expanding women’s health and longevity category. The company describes itself as an independent media platform and maintains a separation between editorial and commercial interests. It does not sell supplements, treatments or branded health protocols.
That model provides a point of differentiation in a health information market where media, wellness products, clinical services and consumer brands increasingly overlap. Adding independent scientific oversight could further support Livelong’s effort to establish credibility as it expands beyond digital publishing into events.
The company, founded by journalist and entrepreneur Brad Inman, reports reaching more than 300,000 readers each month. Its upcoming New York summit will provide the first test of Sims’ broader role, combining her scientific advisory work with direct engagement with speakers and attendees.
As Livelong builds additional events in major U.S. markets in 2027, Sims will help shape both the scientific substance of the programming and the experts brought into the platform. The appointment positions scientific review as part of the company’s growth strategy as it seeks to build a larger audience around evidence-based women’s health and longevity coverage.
