Patient stories

Fueled to perform.

I tore my bicep after eight years as a competitive powerlifter. The team here helped me tremendously. Through physical therapy and nutrition, I actually lost visceral fat during my recovery. Thank you for turning a bad time into good!

Questions

Good to know.

A registered dietitian, every time. Not a general nutritionist or a weekend-certified health coach, but a credentialed clinician who builds a plan around your goals, your training, and your health, working alongside the rest of your medical care team.

More than most people realize. A registered dietitian is trained to provide medical nutrition therapy, which means using food and eating patterns to help prevent and manage real health conditions, always in coordination with your medical care team.

On the medical side, that includes type 1, type 2, and prediabetes; celiac disease and gluten management; food allergies, intolerances, and sensitivities; digestive conditions like IBS, reflux, and inflammatory bowel disease; high cholesterol, high blood pressure, and heart health; kidney disease; PCOS and thyroid concerns; and support before and after surgery or through cancer treatment.

On the performance and everyday side, your dietitian dials in how you fuel training, recovery, and competition, and builds a sustainable plan for losing fat, gaining muscle, or protecting lean mass while on a medication like a GLP-1.

Just as often, the work is about your relationship with food: untangling years of yo-yo dieting or disordered eating, separating genuine food sensitivities from noise, and learning to eat in a way that actually fits your life. Whatever brought you in, the plan is built around you and backed by your testing and labs.

It is a bigger difference than most people think, and it is why we only hire registered dietitians. Registered dietitian, or RD, is a protected, credentialed title. It requires a degree from an accredited program, more than a thousand hours of supervised clinical training, a national board exam, ongoing education, and a state license. That is what qualifies a dietitian to provide medical nutrition therapy and to safely turn your labs and health history into a plan.

Nutritionist, by contrast, is not a protected title in most places, so almost anyone can use it, with anywhere from a short online course to no formal training at all. Every registered dietitian is a nutritionist, but not every nutritionist is a registered dietitian. At THE ARMORY, you always work with a registered dietitian.

You can work with our dietitian through individual visits or as part of a medical membership. We will help you pick what fits.
