A physician-led medical weight loss program in Miami combines a doctor's evaluation, lab work, prescription medication when appropriate, nutrition support and regular progress tracking into one supervised plan. At Nexsis BioHealth in Brickell, the program runs six months for $1,800 and includes the physician consultation, lab review, GLP-1 medication management (semaglutide or tirzepatide), InBody body composition scans and ongoing clinical check-ins.
Medical weight loss has become one of the most searched health services in Miami, and the phrase now covers everything from a five-minute telehealth prescription to a fully supervised clinical program. Those are not the same thing. This guide explains what a physician-led program should include, what happens at each stage, who it is for, what it costs, and how to tell a real program from a medication storefront.
Medical weight loss is weight management supervised by a licensed physician, built on your medical history and lab results rather than a generic plan. It treats excess weight as a medical issue with biological drivers, such as appetite hormones, insulin resistance, thyroid function and sleep, rather than a simple matter of willpower.
In practice, a medical program usually combines four things: a medical evaluation, prescription medication when it is appropriate, structured nutrition guidance, and objective measurement over time. The physician stays involved throughout, adjusting the plan as your body responds.
The core difference is medical oversight. A diet program gives you a plan to follow. A medical program evaluates why your body is holding weight, treats the drivers it finds, and monitors your health while you lose it.
| Commercial diet program | Online prescription service | Physician-led medical program | |
|---|---|---|---|
| Medical evaluation | None | Brief, often a questionnaire | Full physician consultation |
| Lab work | None | Sometimes skipped | Baseline labs before treatment |
| Prescription medication | No | Yes, often the main product | Yes, when appropriate, with dose management |
| Body composition tracking | Scale weight | Self-reported weight | InBody scans of fat, muscle and visceral fat |
| Ongoing physician follow-up | No | Limited | Regular check-ins and protocol adjustments |
| Focus | Calories and points | Getting the prescription | Fat loss while protecting muscle and health |
None of this means diet programs are worthless. Plenty of people succeed with them. But if you have tried structured eating before without lasting results, or you have metabolic concerns like insulin resistance or prediabetes, a medical program addresses things a diet plan cannot.
Your first visit is a one-on-one consultation with a physician, and its purpose is to decide whether medical weight loss is right for you and, if so, what your plan should look like. At our Brickell clinic it covers:
The consultation ends with a clear recommendation. Sometimes that recommendation is that medication is not the right step for you yet, and we will say so.
Before any medication is prescribed, we order a targeted lab panel and take a baseline InBody body composition scan. Labs do two jobs: they show whether treatment is safe for you, and they reveal metabolic factors that may be driving your weight.
A typical baseline panel looks at blood sugar control (fasting glucose and HbA1c), kidney and liver function, cholesterol and triglycerides, and thyroid function, with other tests added when your history calls for them. Insulin resistance, an underactive thyroid or elevated cortisol can all make weight harder to lose, and treating them is part of the plan rather than an afterthought.
The labs also create a starting point. Many patients see improvements in blood pressure, blood sugar and cholesterol over the course of a program, and you can only measure that if you know where you began.
For most eligible patients, the medication at the center of a modern medical weight loss program is a GLP-1 receptor agonist, given as a weekly injection. At Nexsis BioHealth we prescribe semaglutide or tirzepatide, chosen based on your labs, history and goals.
These medications mimic gut hormones that regulate appetite and blood sugar. They slow how quickly your stomach empties and reduce hunger signals, so eating less stops feeling like a constant fight. Both start at a low dose and step up gradually, which reduces side effects such as nausea.
The two drugs are not identical. In the first head-to-head trial, tirzepatide produced more average weight loss, while semaglutide has proven cardiovascular benefits in a large outcomes trial. We compare them in detail in our guide to semaglutide vs tirzepatide. If you have read about newer drugs in trials, our article on whether retatrutide is FDA approved explains where those stand.
Because the scale cannot tell you what you are losing. Rapid weight loss on any GLP-1 medication costs some muscle along with fat. Two people who each lose 30 pounds can end up in very different places depending on how much of that loss was fat and how much was muscle.
That is why our program uses InBody body composition scans at the start and at regular intervals. They measure fat mass, muscle mass and visceral fat, the deeper fat around your organs that is most closely tied to metabolic risk. When a scan shows muscle loss creeping up, your physician adjusts protein targets, activity guidance or medication dose to protect it.
Medication makes eating less easier. It does not teach you what to eat, and it does not build the habits that keep weight off. Our nutrition support is practical rather than prescriptive: realistic guidance based on your lifestyle and metabolic data, with an emphasis on getting enough protein while appetite is low, staying hydrated, and building meals you can sustain after the program ends.
This part matters most at the end. The goal of a six-month program is not just a lower number, but leaving with the habits and understanding to hold it.
The Nexsis BioHealth program runs six months. That length is deliberate. GLP-1 medications are stepped up gradually over the first few months, meaningful fat loss builds over months rather than weeks, and habits need time to settle.
Across the program, you can expect a rhythm like this:
At the end, your physician reviews your results and discusses next steps, whether that is maintenance, tapering or continuing treatment.
Good candidates generally include adults with a BMI of 30 or higher, or 27 or higher with a weight-related condition such as high blood pressure, prediabetes or high cholesterol. They also include people who have not achieved lasting results through diet and exercise alone, and those with metabolic concerns like insulin resistance or elevated triglycerides.
GLP-1 medications are not right for everyone. They are not used during pregnancy, and they are not prescribed to anyone with a personal or family history of medullary thyroid carcinoma or multiple endocrine neoplasia type 2. A history of pancreatitis or gallbladder disease needs careful review. Your physician screens for all of this at the first visit.
The Nexsis BioHealth Medical Weight Loss program is $1,800 for six months, which works out to $300 a month for the complete supervised program. That includes the physician consultation, lab review, InBody body composition assessments, GLP-1 medication management and ongoing clinical support.
For context, GLP-1 medications are now sold direct to self-pay patients by their manufacturers, generally in the range of about $200 to $450 per month depending on dose and program. Those prices change often, so confirm current figures before you budget. Members of our membership program receive 15 to 20 percent off services.
When you compare quotes in Miami, compare complete programs, not monthly medication prices. A cheaper option that skips labs, body composition tracking and physician follow-up is a different product, not a better deal.
Sometimes, partly. Some insurance plans cover FDA-approved GLP-1 medication for a documented obesity or diabetes indication, usually with prior authorization, and coverage rules have tightened in recent years. Supervised wellness programs themselves are generally self-pay. HSA and FSA funds can often be used when there is a legitimate medical indication, so it is worth checking with your plan administrator.
Ask any Miami clinic these five questions before you sign up:
If the answers are vague, or if the plan amounts to a prescription and a shipping label, keep looking.

Book a weight loss consultation and our physician team will review your history, run your labs and tell you plainly whether medical weight loss is the right path for you.
At Nexsis BioHealth in Brickell, the six-month program includes a physician consultation, baseline and follow-up lab review, GLP-1 medication management with semaglutide or tirzepatide, InBody body composition scans, personalized nutrition support and regular clinical check-ins, all for $1,800.
Results vary widely by person, medication, dose and adherence. In clinical trials, patients on GLP-1 medications lost substantial weight over roughly a year to a year and a half. Your physician will set realistic expectations based on your labs, history and goals at the first visit.
Yes. Baseline labs show whether medication is safe for you, reveal metabolic factors like insulin resistance or thyroid issues that affect weight, and give a starting point to measure improvements in blood sugar, cholesterol and other markers over the program.
On average, tirzepatide produced more weight loss in the first head-to-head trial, while semaglutide has proven heart benefits. The right choice depends on your health history, labs and goals, so our physicians decide case by case and can switch medications if needed.
Some muscle loss can happen with any rapid weight loss. That is why we track body composition with InBody scans rather than scale weight alone, and adjust protein guidance, activity and dosing when scans show muscle loss so that most of what you lose is fat.
GLP-1 medications are not used during pregnancy or by anyone with a personal or family history of medullary thyroid carcinoma or multiple endocrine neoplasia type 2. A history of pancreatitis or gallbladder disease needs careful review. Your physician screens for these at the first consultation.
Your physician reviews your results and discusses next steps. Depending on your progress and goals, that may mean maintenance, gradually tapering medication, or continuing treatment, with nutrition habits built during the program supporting whatever comes next.
The supervised program is self-pay. Some insurance plans cover FDA-approved GLP-1 medication for a documented obesity or diabetes diagnosis, usually with prior authorization. HSA or FSA funds can often be used when there is a medical indication.
