Kayla Barnes-Lentz engagement report
@femalelongevity - 494K followers on X
Measured over 35 original posts from a 30-day window, last computed on September 25, 2026.
Engagement
A typical post picks up 48 interactions against 494K followers, an engagement rate of 0.01%. Measured over 35 original posts, its engagement rate beats 34% of 20,182 tracked accounts of a similar size, which puts it in the middle of its size range rather than at either end. Posts are seen about 15K times each, and 0.313% of those impressions turn into an interaction. That is about 3.11% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 2.7 posts a day over the last 30 days, with activity on almost every day in the window. Most posts go out around 17:00 UTC, and Thursday is the busiest day of the week. Of the 35 posts sampled, 54% carry an image or video and 51% are part of a thread. The account's strongest tracked post pulled 310 interactions, about 6.5x its own typical post.

Compared with accounts its own size
Kayla Barnes-Lentz's engagement rate beats 34% of the tracked X accounts closest to it in follower count (20,182 accounts, accounts of similar size (decile 10 of 10)). A percentile is spread evenly by construction, so 50 really is the middle of that group and 90 really is its top tenth.
On engagement per impression rather than per follower it beats 22% of the same group. When those two numbers disagree, the gap is about how far its posts travel rather than how people react to them.

Posting timing
This account posts most often around 17:00 UTC, and Thursday is its busiest day of the week. The bars below are the catalog-wide pattern, with this account's own busiest slot marked. They do not show how this account performs at each hour: we keep one aggregate per account, not one per hour, so that measurement does not exist in our data.

Formats this account uses
Its own posting mix on the left, and what each of those formats does across every account we track on the right. Only formats where the effect clears our publish test appear here, so an empty row is a format we could not measure rather than one that does nothing.
| Format | This account | Catalog effect | 95% interval | Accounts behind it |
|---|---|---|---|---|
| Image or video | 54% of posts | +111% | +108% to +115% | 34K |
| Outbound link | 3% of posts | -41% | -42% to -40% | 32K |
| Typical length | - | +15% | +14% to +16% | 32K |
- 54% of this account's sampled posts carry an image or video. Across the catalog, posts with an image or video run 111% above the same accounts' other posts.
- 3% of its posts carry a link off X. Across the catalog, posts with an outbound link run 41% below the same accounts' other posts.
- Its average post runs 637 characters, which falls in the over 280 characters band. Across the catalog, posts over 280 characters run 15% above the same accounts' other posts.
These are catalog-wide differences applied to this account's own posting mix, not a measurement of how each format performs for this account specifically. We keep one median per account, not one per format per account, so the second thing is not something this data can tell you.

I've been collecting the deepest dataset on a woman's biology for over a decade, and publishing it openly for over six years. Here's some of the testing that entails: - Aging: OrganAge (organ by organ), PhenoAge, DNA methylation clocks (GrimAge, DunedinPACE), skin biological age, telomere length - Cellular: mitochondrial function, oxidative stress (8-OHdG, glutathione, lipid peroxidation) - Immune: immune age, inflammatory markers (hs-CRP, IL-6), autoantibody panels - Hormones: full serum panels + urinary cycle hormones (LH, E3G, PdG, FSH) tracked every cycle, full thyroid panel with antibodies (TPO, TgAb) - Reproductive: ovarian age, ovarian reserve (AMH), full ovulation tracking, vaginal ultrasounds, MRI of endometrial thickness, luteal phase tracking, menstrual blood testing - Urogenital: vaginal pH, vaginal tissue health, pelvic floor function - Heart: coronary CTA + Cleerly for soft plaque, advanced lipids (ApoB, Lp(a), particle count), VO2 max, tracked across cycle phases - Vascular: central aortic blood pressure, arterial stiffness (augmentation index, augmentation pressure), pulse pressure amplification, SEVR - Lungs: spirometry (FEV1, FVC) - Brain: whole-body + advanced brain MRI, volumetric mapping, neurodegeneration blood markers - Sensory: retinal imaging (OCT) - Gut: colonoscopy, zonulin, short-chain fatty acids, inflammation - Microbiomes: gut, oral, vaginal - Metabolic: continuous glucose (I've worn a CGM for 8+ years), insulin, HOMA-IR, metabolomics - Body: segmental body composition, DEXA, grip strength, gait speed, sit-to-stand, balance, Vo2 max - Bone: bone mineral density - Skin: Yearly skin checks, skin biological age - Cancer screening: multi-cancer early detection, breast MRI + breast density, ultrasound, cervical/HPV, breast tear test, full body MRIs - Exposure: mold + mycotoxins, heavy metals, environmental toxins, my water, home professional testing, PFAS - Genetics: whole exome sequencing - Sleep: nightly architecture, HRV, body temperature for 8+ years - Nutrition: micronutrient testing, full iron studies (ferritin, transferrin saturation), metabolic rate Most longevity data is built on men. The female layer, cycle hormones, ovulation, ovarian aging, is what I've been tracking. I've collected over two billion data points. You can see the data and the Female Longevity Protocol I have developed in collaboration with leading female MDs and PhDs. It's the first and only public library of protocols for women. I am not doing this to live forever, or to sell you something. I am doing this to optimize my health, feel better for today and my future family, and in a small, but I hope, meaningful way, contribute to some of the gaps in female health. While also helping elevate the incredible scientists, medical doctors, and labs that are and have been doing important work to understand and optimize our female bodies. This is a group effort, no one can do it alone. If you're a woman please browse my free protocols!

Today is my husband and I’s third year anniversary. Since I’m relatively new to being active on X I haven’t shared our story. We are the original longevity couple. I sent him 8 advanced lab tests before our first date. Including genetic testing, micro biome testing, total toxic burden testing over 200 longevity lab markers, micronutrient testing and more. Our first date was in a multiperson Hyperbaric oxygen chamber at my longevity medicine clinic that I owned at the time. He then did an ozone sauna session and if you’ve ever been in an ozone sauna, you know it takes love to withstand that. We met and were married within four months. At our wedding reception, everything we served was grass fed and grass finished. We had organic bone broth, and a no sugar wedding cake. But our relationship is so much more than health. Yes of course my husband is healthy and he was excited about my antics. (also when he saw my refrigerator for the first time, it was filled with peptides, syringes and mineral water.) he also observed that while I had almost no furniture I had many “health robots” in my apartment. But my husband also loves me like Christ loves the Church. He is the most generous, kind yet strong, inspiring person I’ve ever met. He’s showed me what love is supposed to look like, he makes me feel safe, he protects me, he makes me a better version of myself (and he also eats dinner at 2 pm with me and goes to bed at 8 🙂↔️) In addition to achieving great health, my hope for all of you is that you find your person, the one that truly loves you, the one that is eases your nervous system, and the one that you can cherish forever. Photos: one of the many pieces of Press that have been put out on our relationship and committed to health together, a wedding photo, our first date in HBOT, us on our honeymoon 🤍

EIGHT SLEEP is pretty popular in the wellness world, but we avoided getting one for many years out of concern for “sleeping on an emf” When I lived in LA, we actually slept on a Faraday cage because of all the Wi-Fi signals so close to our house. But I finally got an @eightsleep, and of course, as the most publicly measured woman in the world, I tested it. Here's a video on my findings (I had this professionally tested, my own in-home testing, and it matches the EIGHT SLEEP testing.) Good work @m_franceschetti

How I avoid autoimmunity, even with a genetic predisposition + my protocol that reversed my thyroid antibodies.. 80% of people diagnosed with autoimmune diseases are women, with Hashimoto’s thyroiditis among the most common. I’m 35, female, and genetically predisposed to autoimmunity. I also have selective IgA deficiency, a primary immunodeficiency associated with increased autoimmune risk, so I basically have the highest risk overall. As the most measured woman in the world for the last 6 years, with over a decade of comprehensive labs, I’ve seen my TPO antibodies climb on 3 separate occasions. Every time, the same pattern: - My gut health worsened. - My thyroid antibodies rose. -As my gut health improved, those antibodies fell again. My highest reading was 24. My lab’s cutoff was 35. Still within range, but a change from my baseline. I’ve been catching these changes early, not reversing a diagnosed autoimmune condition. That’s the point of all the testing I do. My goal is to notice meaningful shifts early so I can investigate and act when appropriate. I advise adding TPO antibodies to every thyroid evaluation.

Why everyone feels like crap: - Addicted to your phone - Eats processed foods often - Goes to bed late to stay up watching TV - Rarely moves and going from the couch to the refrigerator doesn’t count - Is disconnected from nature and the sun - Can’t sit alone with their thoughts for 10 minutes - Can’t “find the time” to exercise - Orders takeout packaged in microplastics (eats microplastics all day) - Drinks microplastics all day (bottled water, tap water, soda) - Spends more time on social media than with people - Indulges in substances often (vape, weed, alcohol etc) And we really wonder why everyone feels awful? Start small, but just start doing something. Go on a walk right now, watch the sunset, go to bed early.

- What is Kayla Barnes-Lentz's engagement rate on X?
- Kayla Barnes-Lentz (@femalelongevity) has an engagement rate of 0.01%, based on the median interactions across 35 original posts from the last 30 days against 493,650 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.01%, Kayla Barnes-Lentz sits above the 10th percentile of the 202,259 accounts in this comparison. Those comparison accounts are all large ones, because our scanning cadence is weighted towards big accounts, so this is a ranking among peers of similar scale rather than a ranking across X.
- Does @femalelongevity have real engagement?
- Its engagement rate beats 34% of the tracked X accounts closest to it in follower count (20,182 accounts), which puts it in the middle of its size range group. Ranking inside a size band matters because engagement rate falls as accounts grow, so a raw rate would mostly re-measure the follower count. It is a starting point for a look at follower quality, not a verdict on it.
- When does @femalelongevity post?
- Most posts go out around 17:00 UTC, and Thursday is its busiest day, at roughly 2.73 posts per day across the measured window.
