What Is a DEXA Body Composition Scan?

DEXA stands for Dual-Energy X-ray Absorptiometry. Originally developed as the medical gold standard for measuring bone density, full-body DEXA scanning has expanded into one of the most powerful tools available for body composition analysis — used by elite athletes, research institutions, military fitness programs, and now medical weight loss clinics like Monaco.

 

A DEXA scan works by passing two low-energy X-ray beams through the body at different frequencies. Because bone, lean muscle tissue, and fat absorb these beams differently, the scanner can distinguish between the three with remarkable precision — producing a detailed, region-by-region breakdown of exactly what your body is made of.

 

The result is not a single number. It's a comprehensive report that includes:

 

• Body fat percentage — your total fat mass as a proportion of your overall weight

• Lean muscle mass — how much muscle tissue you carry, broken down by region (arms, legs, trunk)

• Visceral fat measurement — the metabolically dangerous fat stored around your internal organs in the abdominal cavity

• Bone mineral density — an assessment of bone health and fracture risk

• Regional body composition — how fat and muscle are distributed across your left vs. right sides, upper vs. lower body

• Resting metabolic rate estimate — a projection of how many calories your body burns at rest based on your lean mass

 

This is the data that actually drives smart decisions in a weight loss program — and it's the data Monaco builds your progress tracking around.

 

Monaco has partnered with Body Fat Clinic — located at 1401 Commercial Way, Suite 110 in Bakersfield, CA — to provide every Weight Loss Wellness Program member with access to this gold-standard testing as part of their membership. Visit Body Fat Clinic →

WHY DEXA MATTERS ON GLP-1 THERAPY

​

Why Body Composition Tracking Is Critical When Using GLP-1 Medications

​

This is one of the most important things to understand when starting a GLP-1 weight loss program: losing weight is not the same as losing fat.

 

When the body loses weight rapidly — particularly in a caloric deficit created by GLP-1 appetite suppression — it doesn't automatically draw exclusively from fat stores. Without the right support, a meaningful portion of that weight loss can come from lean muscle mass. This is a problem that goes far beyond aesthetics.

 

Why muscle loss matters during GLP-1 therapy:

 

• Muscle tissue is metabolically active — it burns calories at rest. Losing muscle lowers your resting metabolic rate, making weight regain more likely after treatment ends.

• Reduced muscle mass increases the risk of fatigue, weakness, and physical deconditioning — the opposite of what a wellness program should produce.

• Visceral fat (the dangerous fat around your organs) and subcutaneous fat (the fat under the skin) respond differently to caloric deficit. Without imaging, you can't know which you're losing.

• The scale cannot distinguish between fat loss, muscle loss, and water loss. Patients who rely on scale weight alone often make poor decisions about their program.

 

DEXA scanning solves this problem. By measuring your body composition at the start of your program and again after several months of GLP-1 therapy, our team can confirm:

 

• That you are losing fat, not muscle

• Whether your visceral fat — the most dangerous type — is decreasing

• Whether your lean mass is being preserved — and if not, what adjustments to your nutrition, activity level, or supplementation are needed

• Whether your bone density is being maintained throughout treatment

 

This is why Monaco includes DEXA scanning in every Weight Loss Wellness Program membership. Weight loss without this data is just guesswork. Weight loss with DEXA data is a strategy.

​

Benefits of DEXA Body Composition Testing During Your Weight Loss Program

DEXA scanning provides clinical-grade insight that changes how you approach your program — and how your providers manage your care.

 

For patients, DEXA scanning offers:

 

• Accountability beyond the scale — see exactly what is changing in your body and where, even during weeks when scale weight plateaus

• Motivation grounded in data — losing 8 pounds of pure visceral fat in 90 days is a meaningful health win, even if the scale moved less than expected

• Early warning for muscle loss — if lean mass is declining, your team can intervene with nutrition adjustments, protein targets, or resistance training recommendations before it becomes a significant issue

• Personalized program adjustments — DEXA data allows Monaco's clinical team to refine your dosing, supplementation, and lifestyle recommendations based on what your body is actually doing

• Bone density baseline — particularly important for women in perimenopause or menopause, for whom bone density loss is a significant health concern

 

Clinical benefits of tracking visceral fat specifically:

 

Visceral fat — the fat stored around the liver, pancreas, and intestines — is not just a cosmetic concern. Elevated visceral fat is directly associated with increased risk of type 2 diabetes, cardiovascular disease, non-alcoholic fatty liver disease, and systemic inflammation. GLP-1 medications are particularly effective at reducing visceral fat — but without DEXA imaging, this reduction is invisible. Patients can be losing the most clinically important fat in their body and have no way of knowing it from the scale alone.

 

DEXA makes the invisible visible.

​

Who Benefits Most from DEXA Body Composition Scanning?

DEXA scanning is valuable for virtually anyone in a medically supervised weight loss program — but it is particularly important for:

 

• GLP-1 therapy patients — anyone on semaglutide or tirzepatide who wants to confirm they're losing fat, not muscle, and that their body composition is improving appropriately

• Patients with significant weight loss goals — the larger the transformation, the more critical it is to understand exactly what is changing and why

• Women in perimenopause or menopause — hormonal changes during this life stage affect both fat distribution and bone density; DEXA tracks both simultaneously

• Patients with metabolic concerns — insulin resistance, pre-diabetes, or elevated cardiovascular risk benefit significantly from visceral fat tracking

• Patients who have plateaued — if scale weight has stalled but you're staying consistent with your program, DEXA can reveal whether body composition is still improving (it often is)

• Patients combining GLP-1 therapy with strength training — DEXA is the only tool that can confirm muscle is being built while fat is simultaneously being lost

 

DEXA scanning at Body Fat Clinic in Bakersfield is safe, non-invasive, and fast. The full-body scan uses low-dose X-ray radiation — less exposure than a cross-country flight — and takes approximately 15 minutes. No referral is needed. The only contraindication is pregnancy.

 

The DEXA machine at Body Fat Clinic accommodates patients up to 6'6" and 350 lbs. Patients above these measurements may be better suited for BOD POD testing, which Body Fat Clinic also offers and accommodates patients up to 7' and 500 lbs

​

What to Expect During Your DEXA Scan at Body Fat Clinic

Monaco's Weight Loss Wellness Program members receive two DEXA scans through our partnership with Body Fat Clinic — one at the beginning of the program to establish your baseline, and one at a later stage to measure your progress.

 

Scheduling Your scans are coordinated through the Monaco program. Body Fat Clinic is appointment-only — no walk-ins are accepted — and is located at 1401 Commercial Way, Suite 110 in Bakersfield, CA. You can reach them at (661) 873-5852 or book at bodyfatclinic.com.

 

Preparation

• Avoid eating or drinking (except water) for 2–4 hours before your scan

• Refrain from vigorous exercise for 1–3 hours prior

• Stay well-hydrated but avoid excessive water intake immediately before the scan

• No other special preparation is required

 

What to Wear For your DEXA scan, wear comfortable, loose-fitting, metal-free clothing:

• Women: A sports bra without underwire, loose shorts or leggings without metal hardware

• Men: A plain T-shirt and athletic shorts without metal zippers or buttons

• Remove all jewelry, watches, and belts before the scan

• Private changing areas are available at the clinic

 

The Scan Itself You'll lie flat on the scanning table while the DEXA arm passes slowly over your body. The scan is completely painless, produces no sensation, and takes approximately 10–15 minutes. Your total appointment, including result review, is typically under 30 minutes.

 

Your Results

Your DEXA report will include a detailed breakdown of body fat percentage, lean muscle mass by region, visceral fat rating, bone density measurements, and an estimated resting metabolic rate. Monaco's clinical team reviews these results as part of your ongoing program management — using the data to guide your dosing, nutrition recommendations, and any supplementation adjustments.

​

What Your DEXA Data Reveals Over Time

The real power of DEXA scanning is in the comparison between your baseline and follow-up scans. Between scan one and scan two, your report will quantify:

 

• How many pounds of fat you've lost — total and by region

• How much visceral fat has been reduced — the most clinically significant change for metabolic health

• Whether lean muscle mass has been preserved — or whether adjustments to protein intake and activity are needed

• Changes in bone density — particularly relevant for women in menopause or perimenopause

• Shifts in your body's fat distribution — some patients lose fat preferentially in certain areas; DEXA shows exactly where

 

For patients on GLP-1 therapy, this data typically confirms what the scale may be underrepresenting: meaningful reductions in visceral fat and total fat mass, often with preserved or improved lean muscle when nutrition and activity recommendations are followed. Seeing these results in quantitative form is one of the most motivating milestones in any patient's program.

DEXA Scan FAQ

What is a DEXA scan and how is it different from a regular scale or BMI measurement?

A DEXA scan uses low-dose dual-energy X-rays to measure your body's actual composition — how much is fat, how much is lean muscle, and how much is bone. BMI and scale weight provide a single number with no context. DEXA provides a detailed, region-by-region breakdown that tells you exactly what your body is made of and how it is changing. It is the most accurate body composition testing method available outside of a research setting.

 

Why do Monaco members get DEXA scans as part of their weight loss program? Because GLP-1 medications like semaglutide and tirzepatide create rapid caloric restriction through appetite suppression — and without monitoring, this can result in muscle loss alongside fat loss. DEXA allows Monaco's clinical team to confirm that your body composition is improving the right way: losing fat, preserving muscle, and reducing dangerous visceral fat. It also allows us to make informed adjustments to your program when needed.

 

How often should I get a DEXA scan?

Monaco's membership includes two DEXA scans — one at the start of your program to establish your baseline, and one after several months to measure your progress. Patients who want more frequent monitoring can access additional scans directly through Body Fat Clinic. Quarterly scans are a popular choice for patients with active transformation goals.

 

Is the DEXA scan safe?

Yes. Full-body DEXA scanning uses an extremely low level of X-ray radiation — less than the radiation exposure from a cross-country flight, or roughly equivalent to eating a few bananas. The scan is not recommended for pregnant women, but is safe for virtually all other adults.

 

What is visceral fat and why does it matter?

Visceral fat is fat stored around your internal organs — the liver, pancreas, and intestines — in the abdominal cavity. Unlike subcutaneous fat (the fat under your skin), visceral fat is metabolically active and is directly linked to increased risk of type 2 diabetes, cardiovascular disease, fatty liver disease, and systemic inflammation. Reducing visceral fat is one of the most important health benefits of GLP-1 therapy — and DEXA is the only way to measure it accurately outside of a hospital setting.

 

What if my muscle mass decreases during the program?

This is exactly what the DEXA scan is designed to catch early. If your follow-up scan shows a decline in lean muscle mass, Monaco's clinical team will use that data to adjust your nutrition recommendations (typically increasing protein intake), discuss resistance training as a priority, and potentially modify your supplementation protocol. Early detection means early correction — before muscle loss becomes significant.

 

Where is Body Fat Clinic located?

Body Fat Clinic is located at 1401 Commercial Way, Suite 110 in Bakersfield, CA. They are appointment-only — no walk-ins. You can reach them at (661) 873-5852 or book online at bodyfatclinic.com. They offer DEXA scans as well as BOD POD testing for patients who require an alternative.
