I spent $100K on longevity protocols last year - here's why I'm still frustrated (and what I learned)

I'm desperate for some real answers here. As an IT guy who can afford to invest in my health, I went ALL IN on longevity after reading Peter Attia's book. Spent $100K over the past year on every premium longevity clinic, test, supplement, and protocol I could find. And you know what? I'm more confused and frustrated than ever.

Here's what's driving me crazy:

  1. Measurements are a NIGHTMARE
  • I firmly believe "what gets measured gets managed" but holy hell - trying to get reliable data is impossible. My DEXA scans and InBody results are all over the place. Even my VO2 max tests vary by 20%+ between clinics. How am I supposed to know if anything is actually working?
  1. Everyone Claims to be "The Best" (Spoiler: They're Not)
  • I literally just wanted to throw money at the best solution. But every clinic contradicts the others. One says keto, another says plant-based. This place pushes high-intensity training, that place says it'll kill me. I'm losing my mind here.
  1. The Individual Variation is INSANE
  • What's working miracles for others does nothing for me. There's zero framework to handle our different genetics, conditions, and baselines. It's like throwing darts blindfolded.
  1. The Science is Way Behind
  • Started doing n=1 experiments on myself but quickly realized there are too many variables and zero reliability. Can't even get straight answers on basic stuff like optimal exercise protocols or diet approaches. Who has the time or money to validate everything?
  1. The Market is Too Small for Good Solutions
  • Most people just want quick fixes for immediate problems. Nobody's thinking about healthspan 30 years from now. Result? No good mass-market solutions.

I'm at my wit's end here. Have any of you figured out a reliable protocol or framework that actually works? Found any services worth their salt? Please - I need something better than this expensive trial-and-error nightmare I'm living.

------- Edit

Thank you to all my friends for your interest and willingness to help. I'd like to clarify one potential misunderstanding all at once.

I believe I'm already aware of and implementing good practices (nutrition, sleep, exercise, appropriate medical screenings). What I'm really seeking is the optimal approach. Or rather, I'm looking for a framework to determine the best methods in situations of uncertainty.

Here's how I typically think about this. Would anyone like to expand on these thoughts?
