Over 30 years of independent research in health, fitness, and nutrition

When I launched NextFitLife in 2022, I made a promise: every article would be grounded in real science, not trends. No quick fixes, no marketing hype—just honest, practical information to help you make informed decisions about your health.

This Health Hub is the heart of that mission. Here, you’ll find everything I’ve researched, tested, and written about health—organized into 22 obvious topics so you can easily find what matters to you.

Why You Can Trust This Resource

I’m not a medical doctor. I’m a researcher and writer who has spent over 30 years studying the world’s most respected health literature. I’ve read hundreds of books, from How Not to Die by Dr. Michael Greger to Outlive by Dr. Peter Attia, and applied what I learned to my own life. I’ve also spent years understanding the nuances of nutrition, exercise, sleep, and preventive care.

Every claim you read here is backed by peer‑reviewed studies, clinical guidelines, or trusted medical institutions. I don’t accept advertising. I don’t sell products. Every recommendation exists because the evidence supports it—not because someone paid me to say it.

The Books That Shaped My Approach

My guidance doesn’t come from a single source. Over three decades, I’ve studied dozens of groundbreaking books. Here are a few that deeply influenced how I think about health:

  • How Not to Die – Dr. Michael Greger
  • Outlive: The Science & Art of Longevity – Dr. Peter Attia
  • The Body: A Guide for Occupants – Bill Bryson
  • Lifespan: Why We Age – and Why We Don’t Have To – Dr. David Sinclair
  • Why We Sleep – Dr. Matthew Walker
  • Eat to Beat Disease – Dr. William W. Li
  • Spark: The Revolutionary New Science of Exercise and the Brain – Dr. John Ratey

These works, combined with hundreds of peer‑reviewed papers, form the backbone of everything I write.
