AUSTIN — In a carefully curated home, the lights transition from a bright yellow to a calming orange. Each room features custom furniture, deliberately chosen to avoid any volatile organic compounds. Among other health-oriented setups, there’s a hyperbaric chamber, PEMF machines, saunas equipped with red light therapy, a home gym, and a cold plunge pool. Air purifiers are employed to keep any harmful outdoor toxins at bay. Kayla Barnes-Lentz, a longevity entrepreneur, undoubtedly exhibits a meticulous nature in her approach.
At 35, she has gained a notable following for being among the most publicly quantified individuals—being the first woman to undergo ovarian biological age testing. Surprisingly, her ovarian age clocks in at 30, although she is 35.
Barnes-Lentz pursued nutrition studies in college after having lived on a diet primarily consisting of Pop-Tarts and Toaster Strudels. While she didn’t complete her degree, she immersed herself in learning about leading a healthy lifestyle, acquiring various certifications and launching businesses. In 2018, she opened the LYV clinic in Ohio, aiming to enhance her health metrics. However, some worry that her vast audience may be misled by the data she widely shares, given that not all her practices are scientifically backed.
LYV was designed to provide patients with a comprehensive understanding of their health, beyond what a typical doctor’s appointment might reveal, encompassing gut tests and thorough thyroid panels. Barnes-Lentz was the clinic’s initial patient and began sharing her results publicly in 2019.
She reflects, “I thought, ‘Let’s find a science-backed protocol for longevity. How healthy can we make me?'”
As she dove deeper into her personal data, she spotted some early differentiators compared to existing male-centric research. For instance, caloric restriction negatively affected her menstruation.
She notes, “My cycle became dysregulated for the first time,” and added that her thyroid started to decline, resulting in discussions about potential medication. Unsatisfied with this outcome, she decided to reassess.
Her experiences aren’t entirely unusual; women disproportionately represent two-thirds of dementia and Alzheimer’s cases, yet aren’t adequately represented in research. It wasn’t until 1993 that women were notably included in clinical studies, with only a tiny fraction of research funding allocated to women’s health beyond cancer. In many ways, Barnes-Lentz is stepping into this neglected area.
‘We live in an exciting time’
Reading Barnes-Lentz’s protocol in its entirety feels overwhelming, much like trying to digest a dictionary. However, one can certainly extract various practices: recommended scans, supplements, and an overview of her daily habits.
But a crucial medical disclaimer pops up: “This website, including any experimental results presented, is for informational purposes only and does not constitute medical advice.” Other longevity professionals emphasize similar messages. Barnes-Lentz prioritizes fundamental aspects such as sleep, exercise, stress management, nutrition, and social connection over her numerous devices.
A look at her daily routine reveals: she wakes up naturally at 5 a.m., measures body composition, works out, and spends time in the sauna with red light therapy. Breakfast varies but consistently includes fermented foods, protein, greens, and yogurt. Common items might be eggs or salmon paired with arugula or spinach; she also adds collagen peptides and various seeds to achieve around 40 grams of fiber alongside 60 grams of protein in the morning alone.
After beginning work, she takes walks, wears a red light laser cap, and enjoys an hour in her hyperbaric oxygen chamber. Dinner preparation starts around 2 p.m. with dining by 3 p.m., and she tries to be in bed by 8 p.m., having taken her evening supplements along the way. Although she doesn’t feel overly hungry, she will sip still or sparkling water if her stomach grumbles at night.
While she shares her detailed results, it’s clear not every woman’s experience will align with hers. Alongside her husband, Warren Lentz, they have invested significantly in their health technology, which she claims has lowered her ovarian age, verified through Timeless Biotech, a company she also advises.
How exactly does that ovarian age test function? “It measures standard biomarkers like follicle-stimulating hormone and estrogen levels, alongside factors such as lean mass and when menstruation began,” she explains.
Though research hasn’t established a direct connection between biological age reduction in any organ and increased lifespan, the data allows Barnes-Lentz to explore various interventions to better her health. While she cannot pinpoint why her ovarian age appears lower, she is only implementing one additional intervention (hyperbaric oxygen therapy) alongside her lifestyle. With a retest on the horizon, she hopes to gauge its impact.
Still, what does this all mean? According to Dr. Eric Verdin, president of the Buck Institute for Research on Aging, while her followers may see “ovaries five years younger” due to her protocol, the inference lacks solid grounding in data. “Ovarian aging deserves serious research investment,” he notes, commenting that anecdotes shouldn’t be mistaken for evidence.
Yet, Dr. Poonam Desai, an osteopathic physician, points out that Barnes-Lentz’s approach does bring attention to preventative medicine, prompting discussions around ovarian health amidst a heavily targeted fertility conversation.
‘This stuff is very normal for me to talk about’
Barnes-Lentz has assembled a network of healthcare providers to guide her protocol, consulting with specialists for therapies like hyperbaric oxygen treatment and therapeutic plasma exchange.
While she earns money from affiliate links on her site and offers a membership program for more personalized interaction with followers about her protocol, she clarifies that her family’s main income isn’t tied to her platform.
Alongside her husband, she co-owns a sauna company. Interestingly, before their first date, she had him complete a slew of tests, including biomarker analysis.
In a humorous exchange during a recent panel, she remarked, “If a man is going to do a stool sample for you, he’s in it for the long run.” Their unconventional first date took place in a hyperbaric chamber, where they got to know each other—though she did check to see if he was up for the extended time inside. They married in 2023 and share aspirations of living well past 100.
In their home, testing is a perpetual activity, with various gadgets stored away. One device even photographs every stool and urine deposit. “By the way, this stuff is very normal for me to talk about,” she made clear.
As people often ask whether she’s enjoying life or having fun, she senses disbelief. Yet, she maintains she’s far from miserable.
“Who decided that fun means staying out until 3 in the morning?” she challenged during a discussion. “And who concluded alcohol is the only way to celebrate?”
