AUSTIN — The overhead lights and lamps in the home switch from bright yellow to a soft orange. Custom-made furniture sits in every room, free of volatile organic compounds, or VOCs. Elsewhere, there's a hyperbaric chamber, PEMF machines, saunas with built-in red light therapy, a home gym and a cold plunge pool. Air purifiers protect the home's occupants from any toxicity that dare enter from outside. Say what you will about longevity entrepreneur Kayla Barnes-Lentz: The woman is meticulous.
The 35-year-old has built a cult following as the most publicly measured woman in the world, and the first woman to undergo ovarian biological age testing. Her ovaries are 30, not 35, thank you very much.
Barnes-Lentz opted to study nutrition in college after subsisting on a diet of Pop-Tarts and Toaster Strudel. She never graduated, but that didn't stop her from learning everything she could about how to live a healthy lifestyle, including earning certifications and growing businesses, Barnes-Lentz says. She opened clinic LYV in Ohio in 2018 (which she left in 2025), aiming to improve her health metrics in the process. Research doesn't necessarily support all the things she is doing and some experts worry her large following could be misled by the data she shares broadly.
