Abstract

A medical program — not a "skinny shot"

If you found us searching for the "skinny shot" in Miami, here's what it actually is. Medical weight loss is a physician-supervised program: a real evaluation and labs, a personalized plan, nutrition and activity coaching, and — when it's medically appropriate — a GLP-1 medication, with ongoing monitoring and dose adjustment. The medication is a powerful tool, not the whole plan.2,16

And the tools are genuinely new. GLP-1 medicines like semaglutide and the dual-hormone tirzepatide quiet appetite, slow digestion so you feel full longer, and steady the hormones that manage blood sugar — producing the largest weight loss of any medications short of bariatric surgery.1,3,12 Semaglutide has even been shown to cut cardiovascular events.10 But they're prescription drugs with real criteria and real risks, the weight tends to return if you simply stop, and they work best alongside lifestyle change.8,16 We'll walk you through all of it.

Semaglutide ≈ 15%, tirzepatide ≈ 21% average weight loss in trials.1,3
FDA criteria: BMI ≥30, or ≥27 with a weight-related condition.6
Real side effects and contraindications — screened at your visit.5,7
Obesity is chronic: stopping usually brings weight back.8
01 · What it includes & how it works

The program, and the biology

A good medical weight-loss plan treats obesity as the chronic medical condition it is — with evaluation, monitoring and support around the medication, not just a prescription.2

Evaluate

A medical history, labs and a careful look at your goals and risks — including who shouldn't take these medications.7

Personalize

A plan matched to you: the right medication and dose when appropriate, plus nutrition and activity that protect muscle.16,17

Monitor

Regular check-ins to titrate the dose, manage side effects, track progress and adjust — that's the "supervised" part.5

How GLP-1 medicines work

GLP-1 is a hormone your gut naturally releases after eating. These medicines mimic it — and tirzepatide adds a second hormone, GIP. Together they act in three places: the brain (less appetite and "food noise"), the stomach (slower emptying, so you feel full longer), and the pancreas (more insulin when you eat, less glucagon — steadier blood sugar).7,15

The net effect: you naturally eat less and feel satisfied sooner — which is why appetite, not willpower, is what changes most.

02 · What the science shows

The numbers, from the actual trials

Here's average body-weight loss from the pivotal studies, next to older medications and surgery for context. These are trial averages with diet and exercise; your result will be your own.1,3,12

Head-to-head. In the first direct comparison (SURMOUNT-5), tirzepatide produced more weight loss than semaglutide over 72 weeks — 20.2% vs 13.7%.4 Both are highly effective; tirzepatide's dual-hormone action edged ahead. Which one fits you depends on your health, tolerance and goals — that's a clinical decision.

03 · The medications · education

Semaglutide vs. tirzepatide

Two leading GLP-1 medications. They overlap a lot, with a few real differences. Tap one to learn more — this is education, not a recommendation; the right choice is made with a clinician.13

Semaglutide

GLP-1 receptor agonist

Avg. weight loss
≈ 15% average
Key trial
STEP-1, 68 weeks
How it's taken
Weekly injection; dose stepped up 0.25 → 2.4 mg over ~16 weeks

The first of the modern GLP-1 medications for weight. In a separate trial (SELECT) it also lowered the risk of cardiovascular events in people with heart disease — evidence this is about health, not just appearance.1,10

One important distinction. Wegovy and Zepbound are the versions FDA-approved for weight management; Ozempic and Mounjaro are the same molecules approved for type 2 diabetes and used off-label for weight. Same drug, different label — worth knowing when you read headlines.6,7

04 · Candidacy & supervision · interactive

Are you a candidate?

GLP-1 medications have specific FDA criteria, and they aren't right for everyone. Check the general guide below — then a medical evaluation makes the real decision.6

Roughly, where do you fall?

General FDA guide
Generally a candidate

This meets the FDA criteria for chronic weight management with a GLP-1 medication — pending a full medical evaluation and your history.

Why supervision matters

These are prescription medications with real contraindications and side effects. A clinician reviews your history, screens for things like a personal or family history of medullary thyroid cancer, starts you low, and adjusts safely.5,7

What the consultation looks like

A conversation about your goals and history, a focused exam and any needed labs, a real discussion of options (including whether medication is even the right step), and — if appropriate — a personalized plan with follow-up. Book a consultation to start.

05 · Your expected timeline

Slow and steady — by design

The dose is increased gradually to limit nausea, and weight comes off over many months, not weeks. Patience is part of the plan.2,5

Week 1
Start low
A small starting dose lets your body adjust.
Weeks 4–16
Titrate up
Dose steps up gradually to limit nausea.
Months 2–4
Appetite quiets
Less hunger and 'food noise'; early loss.
Months 4–12
Steady loss
Most of the weight comes off in this window.
~16–18 mo
Plateau
Weight settles; focus shifts to maintenance.

This is a marathon. In the trials, weight loss kept going until around 16–18 months before leveling off.1 Because obesity is a chronic condition, most people stay on some plan to maintain their results rather than stopping at goal — more on that next.8

06 · Side effects & safety

The real risks

GLP-1 medications are generally well tolerated under supervision, but they're not risk-free. Here's what to actually expect, and the serious warnings that decide who shouldn't take them.5

Common & usually temporary

Mostly gastrointestinal: nausea, diarrhea, vomiting, constipation, abdominal pain, burping and reflux. They're most noticeable as the dose increases and usually ease with time — which is exactly why the dose is raised slowly.5 Fatigue and some hair shedding can occur.

Serious — and who shouldn't take them

There's an FDA boxed warning for thyroid C-cell tumors (from animal studies); they're contraindicated with a personal or family history of medullary thyroid cancer or MEN 2. Rare but serious risks include pancreatitis, gallbladder disease and dehydration-related kidney injury. They're not for use in pregnancy.5,7 Share your full history first.

07 · The fine print

The fine print

The science is real and the results can be life-changing. Knowing the catches up front is part of how you actually succeed.

It isn't magic — lifestyle still matters

Every pivotal trial paired the medication with reduced-calorie eating and more activity. The drug makes those changes possible by quieting appetite; it doesn't replace them.16

Stopping usually brings weight back

A year after stopping semaglutide, people regained about two-thirds of what they'd lost; tirzepatide showed similar regain.8,9 Obesity is chronic — maintaining results means an ongoing plan, not a finish line.

Protect your muscle

Some of the weight lost is lean muscle (in trials, roughly one part muscle to three parts fat).3 Adequate protein and resistance training 2–4×/week help keep what you lose as fat, not strength.17,18

Cost, access & "compounded" versions

Insurance often won't cover medication for weight loss, so cost is real and ongoing. Be cautious with cheap "compounded" GLP-1s sold online — the FDA-approved products have known quality and dosing. We'll talk through legitimate options at your visit.7

Real science, real supervision

If you're considering GLP-1 weight loss, the right first move is a medical evaluation — to see if it fits you, and to do it safely. That's what we offer in Brickell.

10 · Questions

Frequently asked questions

We offer physician-supervised medical weight loss in Brickell, and GLP-1 medications such as semaglutide may be prescribed when medically appropriate after an evaluation. The first step is a consultation to confirm it's a safe, suitable option for you.6

Tirzepatide may also be an option as part of a supervised plan at our Brickell clinic when it's medically appropriate for you. Which medication (if any) makes sense is decided together with a clinician based on your health, history and goals.13

Under FDA criteria, GLP-1 medications are for adults with a BMI of 30 or higher, or 27 or higher with a weight-related condition such as high blood pressure, type 2 diabetes, high cholesterol or sleep apnea.6 A medical evaluation confirms candidacy and rules out contraindications.7

It depends on your plan and which medication is used, and insurance often does not cover medication prescribed for weight loss — so it's typically an ongoing out-of-pocket cost. We'll give you clear, itemized pricing at your consultation, with no surprises.

A conversation about your goals and medical history, a focused exam and any needed labs, a real discussion of your options (including whether medication is the right step at all), and — if appropriate — a personalized, monitored plan with follow-up visits.2

Yes. For mild-to-moderate laxity, Morpheus8 Body and our skin-tightening treatments firm the skin, and biostimulators can restore lost facial volume. Significant excess skin, though, is best addressed by a surgical consult — we'll tell you which applies to you.

Often, yes. A year after stopping semaglutide, people regained about two-thirds of their lost weight in the trial extension, with tirzepatide showing similar regain.8,9 Obesity is a chronic condition, so maintaining results usually means staying on some form of plan rather than stopping abruptly.
