About Dr. N

I’m Dr. Alexander Nathanson — a physician passionate about helping people navigate the often confusing world of weight, health, and wellness.

I’m inspired by how remarkable the latest evidence-based therapies can be, and I want to share them with you — to guide you through this ever-changing landscape and help you find a path that truly works.

My journey into obesity medicine began with my own struggles with weight. I know firsthand how complex and personal this challenge can be — and how often people living with obesity are misunderstood, even within the medical system.

I’m drawn to this field not only because improving weight can enhance appearance and confidence, but because it can profoundly improve overall health, prevent disease, and extend longevity. Helping people live longer, healthier, and more fulfilling lives is at the heart of my work.

Medical expertise you can trust

I graduated from SUNY Downstate College of Medicine and am board-certified in Family Medicine and Obesity Medicine, with a special interest in cardiometabolic health. I’ve worked in both hospital and outpatient settings, giving me a broad perspective on the challenges people face in achieving lasting health improvements.

A little about me

When I’m not writing or working with patients, I enjoy scuba diving, traveling with my wife, and exploring new places — whether that’s under the ocean or across the globe
