Concierge Medical Nutrition Therapy
Medical obesity.
Treated like the disease it is.
A boutique Medical Nutrition Therapy practice. By application only. Specializing in evidence based, sustained obesity treatment.
By Alexis Beck, MPH, RD, LDN · Twenty five Years
Why this is different
Your body is not failing you. The care around it is.
A GLP is not a treatment plan. Patients are started on the medication, moved up again every month, and given nothing else. No nutrition strategy. No metabolic work. No plan for the phase that decides whether any of it holds.
Then the scale stops moving and they are told they have plateaued.
You did not plateau. You were never actually treated.

What is actually missing
How this is different.
-
Before any prescription
Most patients arrive already medicated and never assessed. The Three-Phase Assessment comes first: medical and behavioral history, the metabolic and inflammatory read with labs and body composition, then the synthesis. You cannot treat what nobody measured.
-
The medication is one input
A GLP changes appetite. It does not teach a body what to do with less food, protect muscle, or decide what happens at the top of the dose. Those are the parts that determine whether any of it holds, and they are the parts this practice does.
-
Sixty-minute sessions
Sixty minutes, not a ten-minute check-in and a refill. Long enough to actually do clinical work. This is the hour the rest of the category has removed.
-
Stabilization is a phase
The months after the loss decide whether it lasts. Metabolic, nutritional and behavioral work, with a protocol. Almost nobody is doing it, which is why the weight comes back.
-
Coordinated with your physician
Alexis sends clinical notes, shares labs, and works as part of your care team rather than parallel to it. Your prescriber keeps prescribing. What changes is that somebody is now doing the other half.
-
A relationship, not a program
Most patients stay with Alexis for years, not weeks, because that is how long sustained weight loss actually takes. She knows your history, your labs, and what has already failed you. A program ends on a schedule. A relationship does not.
-
Private pay
Private pay only, deliberately. It buys real assessment, between-session messaging, and multi-year continuity, none of which fit inside an insurance reimbursement model.
A Note from Alexis
Medical obesity is a disease. It is not simple weight loss.
That distinction is the entire practice. Weight loss is a goal you set. Medical obesity is a condition of metabolic regulation, and it has to be treated.
Right now it is being folded back into ordinary weight loss. The same programs and the same promises, with a prescription added. If you actually have medical obesity that will not hold, because you cannot do this on medication alone. Somebody has to do the other half, and that is the half almost nobody is doing.
Every patient here receives the assessment I wish I had been given twenty years ago. That is why this practice exists.

In her words
Five minutes with Alexis.
The same argument, in her voice: what medical obesity actually is, and why treating it looks nothing like a weight-loss program with a prescription attached.
★★★★★
In a mere two months, Alexis turned my entire life around. Her innate ability to understand people and approach to therapy is unlike anyone else.

Why obesity is not a choice. It is actually a disease.
Obesity is a chronic condition rooted in metabolic dysregulation, not a behavioral failure. Understanding the biology is the first step toward treating it like the medical disease it is.

A look at how GLP-1 medications work, who they are appropriate for, and why they require coordinated medical nutrition therapy to deliver sustained results.

Maybe these will help.
-
Do you take insurance?
NutritionRx is a boutique concierge practice billed privately. We do not process insurance directly. Many patients submit invoices to their plan for partial out of network reimbursement, and we provide the documentation needed to do so.
-
Do you work with patients already on a GLP-1 medication?
Yes. Medication integration with medical nutrition therapy is one of the core services of the practice. We coordinate dosing, protect muscle mass, optimize protein intake, and treat the underlying biology so the medication does what it is supposed to do.
-
Is the care virtual or in person?
Virtual. Patients are seen through secure telehealth sessions from our virtual offices in Boston and New York. This format preserves the depth of the clinical work and removes the friction of commuting to an office.
-
What conditions does NutritionRx treat?
Medical obesity, chronic weight gain and compulsive dieting, GLP-1 medication integration, menopausal weight changes, metabolic syndrome, and disordered eating. The work is medical, not motivational.
