Why this is different
Your body is not failing you. The care around it is.
A GLP is not a treatment plan. Most patients get the prescription and nothing else: no nutrition strategy, no metabolic work.
You did not plateau. You were never actually treated.

What is actually missing
How this is different.
-
Assessment before any prescription
Labs, body composition and your history first. You cannot treat what nobody measured.
-
Sixty-minute sessions
A full hour with Alexis, not a ten-minute check-in and a refill.
-
A plan for after the loss
The months after decide whether it lasts, so they get a protocol too.
-
A relationship, not a program
Most patients stay for years. A program ends on a schedule. This does not.
A Note from Alexis
Medical obesity is a disease. It is not simple weight loss.
Weight loss is a goal you set. Medical obesity is a condition of metabolic regulation, and it has to be treated. Medication alone will not do it.
Every patient here receives the assessment I wish I had been given twenty years ago.

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.
