Dexa Body Composition Scan

Beyond the Scale: What a DEXA Scan in Edmond, OK Reveals About Your Metabolic Health

By Brian Lamkin, DO · The Lamkin Clinic, Edmond, Oklahoma

A DEXA scan is a quick, low-radiation body scan that measures what a scale cannot: how much of your body is fat, how much is muscle, how strong your bones are, and how much dangerous fat sits deep around your organs. That deep fat, called visceral fat, is closely tied to insulin resistance, type 2 diabetes, and heart disease, and it can be high even in people who look lean. A DEXA scan turns body composition into numbers you can act on and track over time. At The Lamkin Clinic in Edmond, we use it as a starting point for metabolic health, weight, and longevity planning, and to confirm that the changes you make are happening in the right tissue.

What Is a DEXA Scan?

DEXA stands for dual-energy X-ray absorptiometry. It uses two low-dose X-ray beams to tell apart the different tissues in your body: fat, lean muscle, and bone. The scan takes about ten to twenty minutes, you stay fully clothed in most cases, and the radiation dose is very low, far less than a standard chest X-ray.

DEXA was first used to diagnose osteoporosis by measuring bone density. Over time it became the clinical reference standard for measuring body composition, meaning the precise amounts of fat and muscle and where they sit. That precision is what makes it useful well beyond bone health.

Why the Scale and BMI Fall Short

A bathroom scale gives you one number: total weight. It cannot tell you whether a pound is muscle or fat, and it cannot tell you where your fat is stored. Two men can weigh exactly the same and have completely different metabolic health.

Body mass index has the same blind spot. BMI is only weight adjusted for height, so a muscular person can be labeled overweight while someone at a normal BMI can carry a risky amount of internal fat. Research consistently shows that where fat sits, especially deep abdominal fat, predicts metabolic and heart risk better than BMI does.

This is the gap a DEXA scan closes. It replaces a single, blunt number with a detailed map of your body.

What a DEXA Scan Measures

A single scan produces several numbers that together describe your metabolic picture.

Body fat percentage: total fat as a share of body weight, measured directly rather than estimated.
Lean muscle mass: how much muscle you carry, and how it is distributed across your body.
Visceral fat (VAT): the deep fat around your organs, the most metabolically dangerous type.
Bone density: a screen for low bone mass and osteoporosis risk.
Regional breakdown: fat and muscle by arms, legs, and trunk, useful for tracking change.
Android/gynoid ratio: whether fat sits more around the middle or the hips, an apple-versus-pear read.

Each of these tells part of the story. The one that changes how patients think about their health most often is visceral fat.

Visceral Fat: The Number That Matters Most

There are two kinds of body fat. Subcutaneous fat sits just under the skin, the kind you can pinch. Visceral fat, or VAT, sits deep in the abdomen, wrapped around the liver, pancreas, and intestines. You cannot see it or pinch it, and a tape measure only estimates it.

Visceral fat behaves differently from the fat under your skin. It is metabolically active, functioning almost like an organ that releases inflammatory signals and free fatty acids directly toward the liver. That process drives insulin resistance, which is the step that precedes type 2 diabetes, and it raises cardiovascular risk. Visceral fat is the strongest fat-related predictor of heart disease, and research shows it can track with abnormal blood pressure, triglycerides, and blood sugar even before those standard tests turn abnormal.

A useful benchmark: a visceral fat area above roughly 100 cm² is generally read as a marker of elevated cardiometabolic risk, and risk climbs further from there. Visceral fat also roughly doubles between the mid-forties and mid-sixties in men, which is one reason midlife is the right time to measure it. Your result is always interpreted alongside your labs and history rather than as a single verdict.

This is why a lean-looking person can still be at risk. What matters is not only how much fat you carry but where it sits, and visceral fat is the depot that carries the most weight for your long-term health.

What Your Results Say About Metabolic Health

A DEXA scan does not diagnose diabetes or heart disease on its own. What it does is place you on a map, and that map connects directly to the metabolic markers we follow in the clinic. High visceral fat raises the odds that fasting insulin, triglycerides, and blood sugar are moving in the wrong direction, often years before a standard screening flags a problem.

We read a DEXA scan alongside bloodwork to see where a patient sits on the insulin resistance spectrum. Together they answer a practical question: is your body composition protecting your metabolism, or working against it? That answer shapes everything from nutrition to whether hormone or medication support makes sense.

Muscle Mass and Healthy Aging

Fat gets most of the attention, and muscle deserves as much. Muscle is where you burn glucose and store metabolic reserve, and it is one of the clearest predictors of strength, mobility, and independence as you age. Muscle loss with age, called sarcopenia, tends to happen quietly, and it accelerates when weight is lost the wrong way.

This is why measuring matters during any weight-loss effort. When someone loses weight through severe calorie restriction alone, a meaningful share of the loss can be muscle. A DEXA scan shows whether the weight coming off is fat or lean tissue, so the plan can be adjusted to protect muscle. That is especially important for patients using metabolic medications, where preserving muscle is a core goal of our medical weight loss program.

Bone Density

Because DEXA began as a bone test, every body composition scan also gives a read on bone density. For men and women in midlife and beyond, that is a valuable early look at bone strength and fracture risk, often before any symptom appears. Low bone density responds to resistance training, adequate protein, vitamin D and other nutrients, and, where appropriate, hormone optimization, so catching it early opens more options.

What We Do With Your Results

Numbers only matter if they change the plan. A DEXA scan at The Lamkin Clinic feeds directly into a strategy tailored to what it shows.

High visceral fat points toward focused metabolic work: nutrition, targeted fat loss, and screening the markers of insulin resistance
Low muscle mass points toward resistance training, protein, and protecting muscle during any weight loss
Low bone density points toward strength training, nutrients, and a hormone review
Hormone patterns that affect body composition are addressed through men’s health and hormone optimization
Recovery, growth hormone balance, and metabolic support are considered through peptide therapy where indicated

Then we measure again. A follow-up scan a few months into a plan shows whether fat is falling, muscle is holding, and visceral fat is coming down. That feedback loop is what turns effort into confirmed progress.

What to Expect

The scan itself is simple. You lie still on a padded table while an arm passes slowly above you. It takes about ten to twenty minutes, there is nothing enclosed or loud about it, and the radiation exposure is very low. You leave with a detailed report, and more importantly with a physician’s interpretation of what it means for you and what to do next.

Who Should Get a DEXA Scan?

A DEXA scan is worth considering if you want a real baseline for your health rather than a guess from the scale. It is particularly useful if you:

Are in midlife and want to understand your metabolic and heart risk
Look healthy or have a normal BMI but have a family history of diabetes or heart disease
Are starting a weight-loss or fitness plan and want to protect muscle
Are using or considering metabolic medications
Are optimizing hormones and want to track body composition over time
Want an early read on bone strength

If you are in Edmond, Oklahoma City, or the surrounding area and want to know what your body is actually made of, a DEXA scan is the clearest place to begin.

Frequently Asked Questions

Is a DEXA scan safe? Yes. A DEXA scan uses a very low dose of radiation, far less than a standard chest X-ray and a small fraction of what you receive from natural background sources in a year. The scan is quick, painless, and non-invasive.

How is a DEXA scan different from a regular scale or BMI? A scale gives only total weight, and BMI is weight adjusted for height. Neither can tell muscle from fat or show where fat is stored. A DEXA scan measures body fat, muscle, bone, and the deep visceral fat that drives metabolic risk, which makes it far more informative about your health.

What is a healthy visceral fat level? A visceral fat area above roughly 100 cm² is generally read as a marker of elevated cardiometabolic risk, with risk rising from there. The number is always interpreted alongside your labs, history, and other DEXA results rather than on its own.

How often should I repeat a DEXA scan? For tracking a plan, every three to six months is common, since that is enough time for meaningful change in fat and muscle to show. For general monitoring, once a year is often reasonable. We tailor the interval to your goals.

Do I need to prepare for a DEXA scan? Preparation is minimal. You will typically be asked to avoid heavy exercise and large meals right before, and to remove metal objects. Any specific instructions are provided when you schedule.
