InBody Scan in Las Vegas: What Your Body Composition Numbers Actually Tell You
Body CompositionLas VegasBy Mia LoPreiato, NP·Body Balance Medical · Las Vegas, NV·8 min read
You've probably seen the InBody kiosk at your gym. Maybe you stepped on one, got a printout, and had no idea what to do with it. At Body Balance Medical, we use InBody body composition scanning the same way a cardiologist uses an EKG — as a clinical tool that directly informs how we build your program. That distinction changes everything about what the results mean.
Body Balance Medical operates clinical-grade InBody units at our Las Vegas clinic — the same devices used in hospital and research settings, not consumer-grade BIA scales.
Why the Scale Is Misleading
The Number on Your Scale Doesn't Know the Difference Between Muscle and Fat
Here's the problem with scale weight: it can't distinguish between a pound of muscle and a pound of fat. It counts water, bone density, the lunch you just ate, and your inflammation levels from yesterday's workout — all the same. Two patients can weigh exactly the same and have completely different health profiles.
This matters more than ever for patients using medical weight loss programs in Las Vegas. Compounded GLP-1 medications like Compounded Semaglutide and Compounded Tirzepatide are remarkably effective at driving scale weight down — but without proper clinical monitoring, some of that weight loss can come from lean muscle mass, not body fat. That's a problem. Muscle is metabolically expensive tissue. Lose it, and you slow your metabolism, reduce strength, and significantly increase your risk of regaining weight after stopping treatment.
InBody scanning tells us what the scale can't: what you're actually losing.

The Device Explained
What InBody Actually Measures
The InBody device uses bioelectrical impedance analysis (BIA) — it sends a safe, low-level electrical current through your body and measures how different tissues resist that current. Fat tissue resists the current differently than muscle tissue. Water conducts it. The device uses multiple frequencies to separate these signals with clinical precision.
Here are the metrics that matter most to our providers at BBM:
A clinical staff member guides a patient through the InBody scan at Body Balance Medical. The test takes under 60 seconds and requires no preparation beyond removing shoes and socks.
Skeletal Muscle Mass (SMM)
The total weight of your skeletal (functional) muscle. This is the number we watch most closely during GLP-1 or TRT programs. It should be going up — or at least holding steady.
Body Fat Mass (BFM)
Total fat weight, reported in lbs/kg. More useful than body fat percentage in isolation, because it shows actual fat mass lost over time regardless of total weight changes.
Percent Body Fat (%BF)
The percentage of your total weight that is fat. Healthy ranges differ by age and sex. Context matters — a 22% body fat reading means something different for a 35-year-old woman vs. a 55-year-old man.
Visceral Fat Level (VFL)
The fat stored around your internal organs — the kind most associated with metabolic disease, cardiovascular risk, and insulin resistance. TRT in men commonly drives visceral fat down within 90 days. This is one of the first places we see positive change.
Total Body Water (TBW)
Broken into intracellular (inside cells) and extracellular (outside cells) water. Unusual extracellular ratios can signal inflammation or fluid retention — clinically useful beyond just hydration status.
Basal Metabolic Rate (BMR)
The calories your body burns at rest. Directly tied to your lean mass. Preserve muscle → maintain metabolism → avoid the weight regain trap. Our providers use this to calculate protein targets for GLP-1 patients.
Segmental Analysis
Muscle and fat measurements broken down by body region: right arm, left arm, right leg, left leg, and trunk. Identifies imbalances, injury patterns, and whether a program is working in specific areas.
Phase Angle (PhA)
The one most people have never heard of. Phase angle measures cellular membrane integrity — essentially, how healthy your cells are. Low phase angle correlates with poor nutritional status and higher disease risk. Improving phase angle is a meaningful health marker beyond weight or composition.
Medical Weight Loss · GLP-1
Why InBody Is Clinically Essential for GLP-1 Programs
GLP-1 receptor agonists work primarily by suppressing appetite. That's the mechanism — and it's effective. But appetite suppression means most patients naturally eat less, and without deliberate clinical guidance, they often don't eat enough protein to maintain muscle mass during rapid weight loss. The result: the scale goes down, the patient looks slimmer, and everyone is happy — until body composition tells a different story.
Clinical Reality
In studies of GLP-1 medications without resistance training or protein guidance, a significant portion of total weight lost came from lean mass rather than fat. That muscle loss directly reduces basal metabolic rate, making long-term weight maintenance harder — and increasing the risk of rapid regain after stopping medication. This is a fixable problem when you have clinical oversight and body composition data.
Here's how InBody data changes the clinical approach at BBM:
Baseline scan before starting: We know exactly what we're working with before your first injection. SMM, BFM, BMR, and visceral fat level are all documented.
Protein target calculation: Your BMR and SMM tell us precisely how much protein you need to preserve muscle while in a caloric deficit. This isn't a guess — it's math.
Progress scans during treatment: We can see whether you're losing fat preferentially or bleeding muscle. If your SMM is dropping, your provider adjusts the protocol — protein supplementation, resistance training guidance, or medication timing modifications.
Post-treatment benchmarking: Body composition data helps determine when you've reached a healthy body fat range versus just a target scale number. That distinction shapes how we approach maintenance planning.
This is the clinical difference between a medical weight loss program and ordering medication from a telehealth service with no monitoring. We're watching your muscle, not just your weight.
Hormone Optimization · TRT & BHRT
InBody and Hormone Therapy: Measuring Whether It's Working
Testosterone is anabolic — that's its job. In both men and women, adequate testosterone levels are essential for maintaining skeletal muscle mass and managing body fat, particularly visceral fat. When testosterone is low, the body tends to shift toward fat storage and muscle loss, regardless of how much someone exercises or how carefully they eat.
Skeletal muscle mass trajectory — are you building or maintaining?
Visceral fat level — typically one of the first measurable improvements
Body fat percentage trend over 90-day increments
Segmental analysis — where is muscle being added?
Phase angle — improving cellular health often precedes scale changes
Why this matters for BHRT in women
Hormonal shifts during perimenopause accelerate visceral fat accumulation
Muscle loss becomes pronounced after 40 without adequate testosterone
InBody tracks whether BHRT is reversing or slowing these trends
Data guides conversation about protein, resistance training, and dosing
Progress visible within 60–90 days of properly optimized hormone therapy
For patients combining TRT or BHRT with a GLP-1 program, InBody becomes even more important — it lets us manage the interplay between anabolic hormone effects and the appetite suppression of GLP-1 medications to optimize body recomposition rather than just weight loss.

Who Reads Your InBody Results at Body Balance Medical
At a gym, your InBody printout might get handed to a personal trainer. At BBM, it goes to licensed nurse practitioners with clinical specializations in hormone optimization and metabolic medicine. The interpretation changes everything.
Mia leads BBM's hormone optimization and medical weight loss programs. Her Biote certification means she interprets InBody data through the lens of hormone function — specifically how testosterone, estrogen, and cortisol levels interact with body composition outcomes. She sets protein targets, adjusts GLP-1 protocols based on muscle preservation data, and uses phase angle and visceral fat trends to inform Biote pellet dosing decisions.

Teresa uses InBody data in the context of aesthetic treatment planning — particularly for patients considering Sculptra or dermal fillers after significant weight loss. Understanding body composition shifts helps her evaluate volume loss patterns, skin laxity context, and treatment sequencing. She's also Biote-certified, so her hormone fluency informs how she interprets changes in body fat distribution for her aesthetic patients.

Your Printout Explained
Understanding the Numbers That Actually Matter
Our providers walk through your InBody results in detail at every scan — explaining what the numbers mean for your specific program, not just handing you a printout.
The InBody printout looks intimidating the first time. Here's a plain-language guide to the sections you should pay attention to:
Body Composition Analysis
The top section. Shows your total weight broken into Body Water, Protein, Minerals, and Body Fat. Think of it as the breakdown of what you're actually made of. Most patients focus only on body fat — but changes in protein mass (a proxy for muscle) tell an equally important story.
Muscle-Fat Analysis
A side-by-side bar chart comparing your skeletal muscle mass and body fat mass to population norms for your height. The visual goal is for your muscle bar to extend further right than your fat bar. If they're reversed, that's the starting point for your program.
Obesity Analysis
Shows BMI alongside body fat percentage. Here's why this matters: BMI is notoriously inaccurate for muscular individuals. A bodybuilder and someone who is metabolically unhealthy can share the same BMI. Body fat percentage in context is the more clinically relevant number.
Segmental Lean Analysis
Muscle mass broken down by body part. This is where we catch asymmetries — one leg significantly weaker than the other, for example — and where we track whether a TRT program is building muscle evenly. Trunk muscle mass is especially important for metabolic health.
The InBody Score at the bottom is a composite summary — useful for tracking progress at a glance, but our providers dig into the underlying numbers rather than managing to the score alone.
Before Your Scan
How to Prepare for Your InBody Scan at BBM
InBody accuracy depends significantly on testing conditions. If you show up dehydrated or immediately after a workout, the results won't reflect your true baseline. Here's how to get the most accurate scan:
3–4
Hours without food
Avoid eating for 3–4 hours before your scan. A full stomach adds weight and can slightly affect fluid distribution readings.
24
Hours without intense exercise
Strenuous exercise causes temporary muscle inflammation and fluid shifts. Wait at least 24 hours — or plan your scan before your workout, not after.
Same
Time of day for every scan
Body composition readings fluctuate naturally throughout the day. For meaningful comparison scans, come in at the same time of day each visit — ideally morning, before eating.
Well
Hydrated (but not over-hydrated)
Drink normally the day before. Avoid large volumes of water immediately before the scan — overhydration skews body water readings just as much as dehydration does.
Also: remove any metal jewelry, wear light athletic clothing, and avoid lotions or creams on your hands or feet before the scan. These affect the electrical contact points.
Frequently Asked Questions
InBody Scan FAQ: What Patients Ask Most
How accurate is the InBody scan compared to DEXA?+
Clinical-grade InBody devices (the 570 and 770 models used in medical settings) have been validated against DEXA scans in multiple peer-reviewed studies, showing agreement within 3–5% for body fat percentage in most populations. DEXA remains the gold standard for absolute precision, particularly for bone density. But for tracking trends over time — which is what matters most in a clinical weight loss or hormone therapy program — InBody is accurate enough to be clinically meaningful and significantly more accessible. We're not using InBody for one-time measurements; we're using it to track your trajectory, and for that purpose, the precision is more than adequate.
Can I get an InBody scan in Las Vegas without joining a gym?+
Yes — and a medical clinic is actually the better environment for it. InBody scanning at Body Balance Medical is integrated into your clinical intake for weight loss or hormone therapy programs. Our providers interpret your results in the context of your bloodwork, symptoms, and health goals — not just the scan in isolation. If you're interested in getting a scan as part of a Medical Weight Loss Candidacy Evaluation, contact our Las Vegas clinic at (702) 843-0590 or apply below. We're located at 7975 W Sahara Ave, Suite 101 in the Summerlin area.
How often should I get an InBody scan?+
For patients in active GLP-1 or hormone optimization programs, we typically recommend scanning every 4–8 weeks. This interval gives enough time for meaningful changes to occur while keeping the feedback loop short enough to adjust protocols before problems become significant. For maintenance phases, quarterly scans are usually sufficient. We schedule these as part of your follow-up appointment cadence — you won't need to remember to book them separately.
What is phase angle on the InBody, and why does it matter?+
Phase angle is a measure of cell membrane integrity — essentially, how well your cells are functioning at a structural level. It's calculated from the relationship between resistance and reactance in the BIA measurement. Higher phase angle correlates with better nutritional status, greater muscle mass, and overall cellular health. It's been used in clinical research as a marker for disease severity and treatment response in cancer patients, dialysis patients, and others with serious conditions. In a wellness context, phase angle trending upward over time is a positive indicator that your nutritional and hormonal interventions are actually working at a cellular level — before changes are visible on the surface or obvious on the scale.
How long does an InBody scan take?+
The scan itself takes 45–60 seconds. You stand on the device's foot electrodes and grip the hand electrodes, stay still, and the machine does the work. Add a few minutes for your provider to review and discuss results with you, and the entire process typically fits within your scheduled appointment time. No special setup, no contrast agents, no radiation.
Is InBody scanning covered by insurance?+
InBody scanning is typically not covered by insurance as a standalone service. At Body Balance Medical, body composition scanning is integrated into your clinical program — it's part of how we evaluate and monitor your progress, not a separate billed service. Ask our team about current program pricing when you schedule your Medical Weight Loss Candidacy Evaluation or Hormone Optimization Assessment.
Is the InBody scan safe? Does it use radiation?+
No radiation whatsoever. The InBody uses bioelectrical impedance — a very small, imperceptible electrical signal that travels through your body tissues. It's entirely safe for the vast majority of people. The main contraindication is for individuals with implanted electronic medical devices (such as pacemakers or defibrillators), who should not use BIA devices. If you have an implanted device, let our team know before your appointment and we'll discuss alternative options for monitoring your body composition.
Can InBody track progress on semaglutide or tirzepatide?+
This is exactly what we use it for. Serial InBody scans every 4–8 weeks during a GLP-1 program let us see whether weight loss is primarily fat-driven (the goal) or whether lean mass is declining faster than we'd like. If we see muscle loss accelerating, we intervene: protein targets get adjusted, resistance training guidance gets reinforced, and in some cases, program timing or dosing is reconsidered. Without this data, you're flying blind on one of the most important variables in long-term weight management success.
