Protein plays a critical role in muscle, recovery, bone health, and long-term longevity—yet many adults still don’t get enough. This article breaks down why protein matters, how much you really need, and how lean mass data can help personalize your intake for stronger, healthier aging.

Winter can be one of the most powerful seasons to invest in your strength, muscle, and long-term health. When training moves indoors and schedules become more structured, the colder months offer a unique opportunity to build habits and foundations that pay off well beyond January.

On October 26, 2025, 60 Minutes profiled Dr. Peter Attia, exploring his philosophy of longevity medicine and the framework he calls Medicine 3.0.

Attia’s message was as simple as it was disruptive:

“The future of medicine isn’t about treatment — it’s about training.”

And training begins with measurement — with DEXA scans, VO₂ Max testing, and metabolic data, the same tools DexaFit has spent over a decade making accessible to the public.

This is a primer, not a prescription. It introduces three levers anyone can explore to improve VO₂ Max. Whether you’re a beginner, enthusiast, longevity-focused, or an elite athlete, this protocol gives you a starting point.

Research continues to show that higher VO₂ Max levels are strongly linked to a reduced risk of chronic disease, increased longevity, and improved vitality—regardless of age. Whether you're an athlete or simply aiming to stay healthy as you age, understanding your VO₂ Max can offer critical insights into your body's inner workings.

For decades, DEXA has stood as the gold standard in body composition analysis, trusted by medical professionals to diagnose osteoporosis, researchers to track the effects of interventions, and elite athletes to optimize their performance. This remarkable technology has quietly revolutionized how we understand the human body. Let's take a look at the science behind this precision instrument.

At DexaFit, we see firsthand how strength training transforms health, performance, and aging. Whether you’re in your 30s or your 70s, adding strength training to your routine can help you preserve function, prevent disease, and even extend your lifespan.

It’s a common goal: boost your metabolism and burn more calories—even while at rest. But is it really possible to rev up your metabolic rate? And what actually works versus what’s just hype?
