Too Many Tools, Not Enough Focus: Why Preventive Health Needs Consolidation and Personalization
My journey with health started through sport and performance.
First through 15 years of first division field hockey, and then more recently, when I caught the endurance bug and started training for triathlons. That’s when I began taking my health even more seriously.
I got my first comprehensive blood panel outside the standard check-up. I invested in a wearable. I started tracking my sleep, HRV, and other metrics. Not out of fear, but out of curiosity and a desire to take ownership of my health, to optimize my daily performance, feel better, and live longer.
And honestly, it felt good. Tangible. Empowering.
But somewhere along the way, it started to feel... exhausting.
If you've ever bounced between three apps, a Substack newsletter, and a new supplement routine, all before your morning coffee, you know what I mean.

WhatsApp Group Summary
Fasting and Ketosis
Derek shared results from his fasting-mimicking diet (FMD), with 2 kg weight loss but no HRV boost.
Breath ketone devices were compared—Acetrack favored over Ketoscan due to calibration-free use.
Outcome: FMD shows mild weight loss; breath tracking is viable—Acetrack wins on usability.
Blood Testing and Biomarkers
Simon asked about blood testing in Germany. Derek shared experience with Lucis Health; Tipi is building a new service.
Coronary Artery Calcium Score (CACS) and blood panels were prioritized for longevity.
Outcome: Lab access is improving, but users still seek balance between ease, depth, and cost.
Supplement Reviews
Glycine was praised for sleep and skin, especially in combo with collagen or NAC.
Discussions around Alpha Ketoglutarate (AKG) revealed mostly neutral results.
Outcome: Some supplements deliver subtle benefits; others like AKG show inconsistent effects.
Devices and Bio Age
Whoop’s new Bio Age feature sparked comparisons with Oura. Jonas and Karol shared impressive deltas (up to -9 years).
Members noted the algorithms differ substantially and shouldn’t be compared directly.
Outcome: Bio Age tools motivate—but users value personal deltas over absolute numbers.
