The Physician Who Runs This Test Has Seen What Visceral Fat Actually Looks Like.
Your Doctor Weighs You in Pounds. We Measure Where Your Dangerous Fat Actually Lives.
When your primary care doctor measures your body, they put you on a scale, write down a number in pounds, divide it by your height squared, and call the result your BMI. Then they hand you a chart with a color-coded zone. Normal, overweight, obese. They have no idea whether the weight on the scale is fat, muscle, or water. They have no idea where the fat lives.
Two people with identical BMI can have completely different body compositions. One could be 18% body fat with 8 sq cm of visceral fat. The other could be 32% body fat with 65 sq cm of visceral fat. Both show up as the same BMI. One is at moderate metabolic risk. The other has the visceral fat profile of a pre-diabetic. The scale cannot tell the difference. The BMI calculation cannot tell the difference. The InBody 580 can.
What the InBody 580 Measures (And Why Each Number Matters)
Total body fat percentage.
What portion of your weight is fat. More useful than BMI because it accounts for muscle mass, but still only part of the picture.
Visceral fat area in square centimeters.
The dangerous fat inside the abdominal cavity. This is the number Dr. Sweeney tracks at every retest. Visceral fat drives insulin resistance, cardiovascular disease, cognitive decline, and chronic inflammation. The InBody 580 measures it. Your scale does not.
Segmental skeletal muscle mass.
How much muscle you have in each arm, each leg, and your trunk, measured separately. Identifies muscle imbalances, muscle loss patterns, and the effect of training protocols on lean mass by body region.
Hydration status.
Total body water and intracellular vs extracellular fluid ratio. Edema, dehydration, and water retention all affect the scale number. The InBody 580 separates them from fat and muscle.
Lean mass.
This is muscle and bone, the foundation of your resting metabolic rate and longevity.
Visceral Fat Is the Single Most Dangerous Fat in Your Body. The InBody 580 Measures It in Under 5 Minutes.
Visceral fat is the fat that sits inside the abdominal cavity, wrapped around the liver, pancreas, intestines, and other organs. Unlike subcutaneous fat (the fat under your skin), visceral fat is metabolically active. It releases inflammatory signals. It drives insulin resistance. It lowers testosterone in men. It contributes to fatty liver disease, cardiovascular disease, type 2 diabetes, and cognitive decline.
The only way to know your visceral fat area is to measure it. BMI does not measure it. Scale weight does not measure it. Waist circumference gives a rough proxy but misses patients who carry visceral fat internally without a large waist measurement. Dr. Sweeney considers the visceral fat area in square centimeters the single most actionable number from the InBody 580. It is the number she watches most closely at every quarterly retest.
What the InBody 580 Returns: A Complete Body Composition Profile in Under 5 Minutes
The InBody 580 delivers a printed body composition report after every scan. The report includes total body fat percentage, segmental skeletal muscle mass for each limb and trunk, visceral fat area in sq cm, body weight, BMI (for comparison only), hydration status, lean body mass, and the body composition history chart that tracks every measurement across time.
Most Sano patients retest every quarter. Patients on the Weight Loss Program often retest more frequently in the first six months to track fat-only loss versus total weight loss. Sano Longevity members receive unlimited InBody 580 scans at all tiers. Retesting frequency is driven by clinical need, not by cost.
Three Sano Patients. Three Visceral Fat Numbers. Six Months.
Patient 1 (50-year-old female nurse practitioner):
Visceral fat down 26 sq cm in 6 months. Total weight down 16 lbs. Fat loss 12 lbs pure fat. VO2 max up 33%. She had been on a GLP-1 from an online prescriber. Zero fat loss until Sano built a real protocol around the measurement.
Patient 2 (51-year-old male, third shift worker):
Visceral fat reduced. Total weight down 21 lbs. Fat loss 18 lbs pure fat. Lean mass up 3 lbs. Resting metabolic rate up 100 cal/day. His wife noticed him slowing down. He had never taken his health seriously. The InBody 580 showed Dr. Sweeney exactly where to start.
Patient 3 (41-year-old female business owner):
Body fat percentage 22% to 17%. Total weight down 12 lbs. Fat loss 10 lbs pure fat. Successfully weaned off GLP-1 and maintained. The muscle preservation protocol, built from her InBody and VO2 data, is why she kept the weight off.
Who Should Get Body Composition Testing in Louisville
Anyone whose primary care doctor uses BMI as a body composition measurement.
Which is almost everyone. BMI is a height-and-weight calculation. It is not a measurement of what your body is made of.
Anyone trying to lose weight.
The number on the scale does not tell you whether you are losing fat, muscle, or water. The InBody 580 does. Without it, you cannot know whether your weight loss protocol is actually working.
Anyone on GLP-1 medication.
GLP-1 causes weight loss. It does not distinguish between fat and muscle. The only way to verify fat-only loss is to measure body composition before, during, and after the protocol.
Anyone building a longevity plan.
Muscle is the organ of longevity. The InBody 580 is how you measure whether you are building it, maintaining it, or losing it. Every Sano longevity patient starts with an InBody 580 on day one.
What to Expect at Your Body Composition Scan at Sano
Step 1 (2 minutes):
You arrive in light clothing, no metal accessories, properly hydrated. You step on the InBody 580 platform.
Step 2 (under 1 minute):
You stand still and hold the grips. A low-level electrical current passes through your body and measures resistance in different tissue types. No radiation. No needles. No discomfort.
Step 3:
The platform generates your complete body composition report. Printed on-site.
Step 4 (approximately one month later, for program members only):
Roadmap appointment with Dr. Sweeney. She walks through your InBody results alongside your VO2 max, resting metabolic rate, and blood panel in a 60 to 90 minute session. Your training and nutrition protocol is built from this data.
Frequently Asked Questions About Body Composition Analysis in Louisville
Six questions patients ask most often about InBody 580 body composition analysis at Sano Longevity.
What is body composition analysis and why is it different from BMI?
Body composition analysis measures what your body is actually made of: fat mass, muscle mass, water weight, and bone. BMI is a calculation that uses only your height and weight. Two people with the exact same BMI can have completely different body compositions. One could be 18% body fat with 8 sq cm of visceral fat. The other could be 32% body fat with 65 sq cm of visceral fat. Both show up as the same BMI. Sano Longevity uses the InBody 580 to measure where fat lives on the body, segment by segment, and how much of it is the dangerous visceral fat that drives chronic disease.
What is visceral fat and why is it more dangerous than other fat?
Visceral fat is the fat inside the abdominal cavity, wrapped around the liver, pancreas, intestines, and other organs. It releases inflammatory signals, drives insulin resistance, lowers testosterone in men, contributes to cognitive decline, and is one of the strongest predictors of cardiovascular disease, type 2 diabetes, fatty liver disease, and dementia. The InBody 580 measures visceral fat area in square centimeters, which is the metric Dr. Sweeney tracks at every Sano body composition retest.
How does the InBody 580 work?
The InBody 580 uses bioelectrical impedance analysis (BIA). You stand on the platform with your hands holding the grips. The device sends a low-level electrical current through your body and measures the resistance in different tissue types. Fat, muscle, and water conduct electricity differently. The scan takes under 5 minutes, requires no radiation, and returns a complete body composition profile including segmental muscle mass by body part, visceral fat area in sq cm, total body fat percentage, and hydration status.
What does the InBody 580 measure that other body composition methods do not?
The InBody 580 measures segmental muscle mass separately for each arm, each leg, and the trunk. It measures visceral fat area in square centimeters. It returns a complete body composition profile in under 5 minutes, with no radiation. Sano Longevity patients get unlimited InBody scans as part of both the Longevity Program and Weight Loss Program memberships.
How often should I get a body composition scan?
Most Sano patients retest body composition every quarter. Patients on the Weight Loss Program often retest more frequently in the first six months to track fat-only loss. Sano Longevity members receive unlimited InBody 580 scans at all tiers, so retesting frequency is determined by clinical need, not by cost.
How much does body composition analysis cost at Sano?
Body composition analysis is included in both the Longevity and Weight Loss membership programs at Sano Longevity, with unlimited retesting at all tiers. Standalone InBody 580 scans are also available for non-members. Sano Longevity is a membership-based practice. HSA and FSA eligible. See the pricing page for current standalone rates.
