Dr. Josh Lindsley, DO, DABOM

I Lost 80 Pounds. But I Did It Wrong First.

That failure became my obsession—and the reason Highland Longevity exists. As a board-certified obesity medicine physician, I now help patients in Fort Worth, Southlake, and Keller transform the right way: preserving muscle, tracking data, and getting results that last.

The Doctor Who Had to Learn the Hard Way

I'm Dr. Josh Lindsley, DO, DABOM—a board-certified obesity medicine physician and emergency medicine doctor. When I started GLP-1 medications, I dropped 70 pounds. I thought I had won.

But something felt wrong. I was lighter on the scale, yet I felt weaker. My metabolism tanked. I looked smaller, but I wasn't stronger—I was depleting.

So I got a DEXA scan—the same gold-standard body composition technology we use at Highland Longevity. The results were sobering: despite all that weight loss, I was sarcopenic (suffering from severe muscle loss) with 25% body fat.

"Weight loss doesn't equal health. I learned that the hard way so my patients don't have to."

That failure became my obsession. I rebuilt myself from the ground up—tracking everything, preserving muscle, optimizing hormones. The protocol I developed is now the foundation of everything we do at Highland Longevity.

In my second transformation phase, I lost an additional 17 pounds of pure fat while actually gaining lean muscle mass. 99% of the weight I lost was fat—verified by DEXA.

Highland Longevity exists so you don't waste years making my mistakes.

Data-Driven Approach

Our Philosophy: Stop Guessing. Start Knowing.

Most weight loss clinics sell you a number on a scale. We think that's backwards. The scale lies—it can't tell you whether you're losing fat or muscle, whether your metabolism is improving or crashing, or whether your protocol is actually working.

At Highland Longevity, we measure everything. We track your fat mass, lean mass, bone density, metabolic rate, and cardiovascular fitness. Then we build a protocol around your data—not a one-size-fits-all template.

1

Measure First

Comprehensive diagnostics including DEXA scan, VO₂ max, RMR testing, and full lab panels. Know exactly where you're starting.

2

Personalize Everything

Your protocol is built around your data, your goals, and your lifestyle. No cookie-cutter programs here.

Track Progress

Regular check-ins and quarterly data reviews. See the proof that your protocol is working—not just hope it is.
