GLP-1s are changing weight loss, but that’s only half the story. Few are talking about what GLP-1s don’t fix. Across 1,000+ test centers and tens of thousands of DEXA scans, we’re seeing a very different pattern emerge: Hidden post-GLP-1 changes inside the body that may affect longevity and healthspan if left unaddressed. Hint: It has to do with muscle loss. Losing muscle isn’t just an aesthetic issue. It’s one of the strongest predictors of future frailty, insulin resistance, mobility loss, metabolic slowdown, and early mortality. This article breaks down what we’re seeing behind the scenes, and why understanding what’s happening beyond the bathroom scale matters now more than ever.

Many people track the wrong health metrics. Weight, cholesterol, and blood pressure only tell part of the story. After five years of building Fitnescity Health and partnering with nearly 1,000 hospitals and diagnostic centers, one thing has become clear: Eight numbers consistently predict long-term health, disease risk, and longevity. This week’s article breaks down the eight metrics every adult should know by 40, and why they matter far more than the ones we’re used to checking.

Most people think of blood tests as the cornerstone of preventive care. But your annual labs only tell half the story. The DEXA Scan fills in the missing half, revealing how much muscle you carry, where fat is stored, and whether your bones are quietly weakening. Research shows these three numbers—visceral fat, muscle mass, and bone density—are as predictive of chronic disease and longevity as cholesterol or glucose. It’s time to make DEXA a standard part of every annual physical. 👉 Here’s my latest piece. I’d love for you to read it, reflect, and subscribe.

Over the past year, one preventive test has been everywhere —from longevity doctors to business leaders to everyday health enthusiasts. It’s called the Calcium Score Test, and it might be one of the most important five minutes you’ll ever spend on your health. This week, I wrote about my experience taking the test: what I learned, why it matters, and how a simple scan can provide life-saving information about your heart health. You can read it in my new LinkedIn newsletter, “Own Your Health.”

Most people think cholesterol, blood pressure, or body weight are the best predictors of long-term health. But research — and now CBS’s 60 MINUTES — is shining a spotlight on another, far more powerful number: VO2 Max. It’s not just about fitness. VO2 Max is one of the strongest predictors of longevity and overall healthspan ever studied. What makes it remarkable is how actionable it is: You can test it, track it, and improve it, often within weeks. At Fitnescity Health, VO2 Max testing has become one of the most requested assessments on our platform. We’re proud to be the world’s largest platform for VO2 Max testing. 💡 Here’s my latest piece.
