What to Expect at Your First Medical Weight Loss Consultation

Your first consultation is mostly a conversation, and the point of it is to answer two questions: whether a GLP-1 protocol is safe for you, and what yours should look like. You'll talk through your weight history and your medical history, your provider will tell you what bloodwork they need, and if you're a candidate you'll leave with a plan for what happens next.

Nobody is going to weigh you in front of a room or hand you a meal plan photocopied from a binder. If you've had a bad experience with a weight loss program before, that's worth saying out loud in the first five minutes, because it changes how the rest of the conversation should go.

What the Consultation Is Actually For

Two things, and they're different jobs.

The first is screening. GLP-1 medications carry a boxed warning for thyroid C-cell tumors based on rodent studies, and they're contraindicated in anyone with a personal or family history of medullary thyroid carcinoma or multiple endocrine neoplasia syndrome type 2.⁴ Pregnancy, a history of pancreatitis, and significant gastrointestinal disease including gastroparesis all matter too. None of this is a long conversation for most people, but it's the reason a legitimate program asks before it prescribes.

The second is design. Two people with the same starting weight can need very different protocols depending on their labs, their medication list, how much muscle they're carrying, how they've responded to things in the past, and what they're actually trying to accomplish. Someone who wants to lose 60 pounds and someone who wants to drop 15 while holding onto their strength are not on the same plan, even if they start on the same medication.

The History Your Provider Will Take

Come ready to talk about a few things. You don't need to prepare a document, but thinking about these ahead of time makes the visit more useful.

Your weight history. What your weight has done over the last decade, not just what it is today. Whether it climbed slowly or jumped after a specific event, like a pregnancy, a surgery, a new medication, or a stretch of high stress.

What you've already tried. This one sometimes feels like a confession, and it shouldn't. Every diet, program, and app that didn't hold is information about what your body and your schedule actually respond to.

Your current medications and supplements. All of them. Some medications drive weight gain on their own, some interact with how a GLP-1 affects blood sugar, and some absorb differently when your stomach empties more slowly.

Your medical history. Thyroid conditions, pancreatitis, gallbladder issues, diabetes, kidney problems, GI conditions, and any family history of the thyroid cancers named above.

How you actually eat and move. Not an audit. Your provider needs to know whether you're eating once a day at 9pm, whether you're lifting, and whether you travel constantly, because all three change what a workable plan looks like.

What you want. "Lose weight" is a starting point. A number, a date, a pair of jeans, or a lab value you want to move is something a protocol can be built around.

Bloodwork, and Why It Comes Before the First Dose

Labs tell your provider two things: whether a GLP-1 is safe for you right now, and what your starting point looks like on paper so there's something to compare against later.

A typical panel looks at blood sugar and HbA1c, thyroid function, kidney and liver markers, and a lipid panel. Depending on your history your provider may add more. If you've had bloodwork in the last several months through your primary care office, bring it, because it often covers most of what's needed.

Defiant writes the lab order, but the draw happens at your primary care office or through Rythm Health, since we don't run blood draws in the clinic. Results usually take a few days to a week, and your provider reviews them before writing a protocol. That review is part of what separates a medically supervised weight loss program from a prescription mailed to your door.

The Body Scan, and Why the Scale Isn't the Measurement

Every weight loss program at Defiant starts with a Styku 3D body composition scan. You stand on a platform, it rotates, and about 30 seconds later you have a model of your body with fat mass, lean mass, and circumference measurements attached.

The reason this matters more than your weight: a meaningful share of what people lose during rapid weight loss is lean tissue, and the bathroom scale reports both kinds of loss as the same good news. If you drop 12 pounds and four of them are muscle, the scale congratulates you and your metabolism quietly gets worse. Tracking body composition every four weeks catches that pattern early enough to do something about it, usually through protein intake and resistance training rather than a change in medication. We went deeper on that in what the DXA data shows about body composition on a GLP-1.

This is also the honest answer to "will I lose muscle on a GLP-1." Some lean mass loss happens with any significant weight loss, medication or not. The plan is to measure it and push back on it, not to promise it won't happen, and the protein and training protocol we use to protect muscle is worth reading before you start rather than after.

What the Research Says You Can Expect

Clinical trial numbers are the ceiling, and it helps to see them next to the real-world ones.

In the STEP 1 trial, 1,961 adults with overweight or obesity taking semaglutide 2.4 mg weekly alongside lifestyle support lost an average of 14.9% of their body weight over 68 weeks, compared with 2.4% on placebo.¹ In SURMOUNT-1, participants on tirzepatide 15 mg weekly lost an average of 20.9% over 72 weeks.²

Then there's what happens outside a trial. A Cleveland Clinic analysis of 3,389 adults who started semaglutide or liraglutide in ordinary clinical practice found average weight loss of 5.1% at one year on semaglutide, well under the trial figures.³ Most of that gap sits in the breakdown. Only 40.7% of the full cohort still had persistent medication coverage at one year, and among semaglutide patients who did stay on it and were being treated for obesity, average loss was 12.9%.³

Those two numbers, 5.1% and 12.9%, come from the same medication. The gap is mostly about whether people stayed on treatment long enough to reach an effective dose, which is exactly what the trial protocols were designed to make happen. That's the case for a program with structure around it rather than a prescription and a phone number, and it's a fair thing to ask any clinic about before you sign up.

Questions Worth Asking Them

You're interviewing the clinic as much as they're evaluating you. A few that tend to separate programs quickly:

• How often do you adjust my dose? Defiant titrates every two weeks. Many telehealth programs run on a monthly schedule, which means a dose that isn't working takes four weeks to change instead of two.
• Who do I contact between visits, and how fast do they answer? Side effects show up on a Tuesday, not at your next appointment.
• What exactly is included in the monthly price? Medication only, or medication plus provider oversight, check-ins, and scans?
• How do you track progress? Scale weight alone is a weaker answer than body composition.
• What's the plan when I plateau? Everyone plateaus eventually. A program that hasn't thought about it will improvise.
• What's the plan for protecting muscle? Listen for specific protein targets and a resistance training recommendation rather than a general reassurance.
• What happens if I want to stop? Weight regain after stopping is well documented, and a clinic should be able to talk about maintenance without getting cagey.

Cost, and What's in It

Custom GLP-1 protocols at Defiant start at $295/mo. That includes the medication, provider oversight, bi-weekly titration check-ins, weekly nurse access, and monthly body composition scans. Defiant members save 20%.

We don't bill insurance directly. If you want to know whether your own plan covers any part of GLP-1 treatment, the place to look is your plan's drug formulary and its prior authorization requirements for weight management, which is a call your insurer can answer faster than we can.

The consultation itself is free, and there's no obligation attached to it. Plenty of people book one, find out they're a candidate, and decide the timing isn't right. That's a normal outcome.

If You're a Candidate, Here's What Happens Next

Your provider confirms the protocol, you start on a low dose, and you check in with the nurse team that first week. Dosing adjusts every two weeks based on how you're tolerating it and how you're responding, which is faster than the monthly cadence most online programs use. Your next body composition scan lands at the four-week mark.

Most people notice appetite changes in the first week or two, before the scale does much of anything. The first month runs on a starter dose by design, so the larger changes come later. Our week-by-week guide to the first month on a GLP-1 covers what that stretch actually feels like.

Consultations and follow-ups are available in-clinic in Lisle or by telehealth for patients across Naperville, Downers Grove, Wheaton, and the western suburbs. The initial body composition scan happens in-clinic.
