Understanding Your Body Composition
Your weight is made up of fat, muscle, water and other lean tissue.
A standard scale shows total weight but cannot explain what changed. Weight loss may include fat, water and muscle; weight gain may reflect muscle, fat or temporary fluid changes.
Body composition analysis provides estimates that help the clinician discuss whether your plan is reducing fat while protecting muscle, whether abdominal fat remains a concern and whether test conditions may have affected the reading.
At Apgujeong Hana Clinic, the report is interpreted alongside waist measurement, medical history, medications, activity, nutrition and relevant metabolic tests.
π
Body-Fat Percentage
The estimated proportion of total body weight represented by fat mass.
πͺ
Skeletal Muscle Mass
An estimate used to follow muscle preservation, gain or loss over time.
π«
Visceral-Fat Estimate
Provides additional context about fat concentrated around the abdomen.
π§
Body-Water Information
Helps explain why hydration and fluid shifts can change the test result.
BMI Versus Body Composition
Two people can have the same BMI but a very different balance of fat and muscle.
βοΈ
Scale Weight & BMI
Useful for a quick overview and population-level risk screening, but these measures do not distinguish fat mass from muscle mass or show where lean tissue is distributed.
π
Body Composition Analysis
Adds estimated fat, skeletal muscle, water and segmental information so progress can be discussed in greater detail. It complements BMI rather than replacing the full medical assessment.
A lower number on the scale is not the only goal
During medical weight management, the clinic also considers muscle preservation, waist change, metabolic health, fitness, symptoms and whether the plan is sustainable.
What The Report May Include
A structured view of fat, muscle, water and body balance.
Body-Fat Percentage
Estimated fat mass expressed as a percentage of total body weight.
Fat Mass
The estimated total amount of fat tissue, usually displayed in kilograms.
Skeletal Muscle Mass
An estimated measure of muscle linked to movement, strength and metabolic function.
Segmental Lean Analysis
Compares estimated lean mass across the arms, legs and trunk when supported by the device.
Visceral-Fat Indicator
An estimate used to discuss abdominal fat and cardiometabolic risk in context.
Total Body Water
Water-related values help explain fluid balance and possible variation between tests.
Who May Benefit?
Useful for weight management, metabolic care, fitness and healthy aging.
Weight-Loss Patients
Track whether change appears to come mainly from fat while monitoring muscle preservation.
Medication Follow-Up
Add composition trends to follow-up for GLP-1, tirzepatide or other medical weight treatments.
Metabolic Risk Review
Use abdominal-fat and body-composition context alongside glucose, lipids and blood pressure.
Fitness & Strength Goals
Monitor muscle-focused changes that may not be visible from weight alone.
Muscle-Loss Concerns
Support discussion of low muscle, reduced strength, inactivity or healthy-aging goals.
International Patients
Receive the test process, report explanation and follow-up plan in English.
How The Test Works
Bioelectrical impedance estimates composition from how a small signal travels through the body.
β‘
A quick, non-invasive measurement.
You usually stand barefoot on the analyser and hold the hand electrodes. The system measures electrical impedance and uses device-specific algorithms to estimate body compartments.

Review The Report
The clinician explains the values, reference ranges and possible limitations.
The result is an estimate, not a direct image of body tissue
Different devices and prediction equations may produce different numbers. Use the same device and similar conditions when monitoring progress.
Preparing For Your Test
Consistent preparation helps make repeat measurements easier to compare.
Follow any instructions provided by the clinic. Preparation may be adjusted for your appointment time, medical needs or the specific analyser.
Normal Hydration
Avoid arriving unusually dehydrated or after excessive fluid intake.
Meal Timing
Avoid a large meal immediately before testing and follow clinic guidance.
Avoid Heavy Exercise
Strenuous activity can change fluid distribution and influence estimates.
Use The Restroom
Empty your bladder before the test when possible.
Repeat Consistently
For follow-up, test at a similar time and under similar conditions.
Temperature and recent activity also matter
Allow your body to settle after arriving from very hot or cold weather, and tell the clinic about recent intense exercise, alcohol intake, illness, swelling or major changes in hydration.
Understanding Your Results
The clinician looks for patterns—not one “perfect” number.
Your Starting Point
Baseline values help create realistic goals based on health, lifestyle and treatment priorities.
Fat-Mass Trend
Follow whether body-fat estimates are moving in the intended direction over time.
Muscle Preservation
Review whether skeletal muscle remains stable during calorie reduction or medication treatment.
Segmental Balance
Large side-to-side differences may need clinical context, repeat testing or further assessment.
Central-Fat Context
Interpret visceral-fat indicators together with waist, blood pressure, glucose and lipids.
Meaningful Change
A single small fluctuation may reflect water or testing conditions rather than true tissue change.
WEIGHT DOWN + MUSCLE STABLE
Often a more useful pattern than weight loss alone.
WEIGHT STABLE + MUSCLE UP
Can represent positive recomposition even without scale loss.
WEIGHT DOWN + MUSCLE DOWN
May prompt review of protein, resistance exercise and treatment pace.
SUDDEN LARGE CHANGE
May require repeat testing and review of hydration or illness.
Accuracy & Important Limitations
Hydration and medical conditions can affect bioelectrical impedance estimates.
π Tell The Clinic Before Testing
β
You have a pacemaker or another implanted electronic medical device.
β
You are pregnant or may be pregnant.
β
You have significant swelling, kidney disease, ascites or major fluid imbalance.
β
You recently completed intense exercise, sauna use or heavy alcohol intake.
β
You cannot stand safely or maintain the required testing position.
β οΈ Do Not Interpret The Report Alone
!
The test does not independently diagnose obesity, sarcopenia or fluid disorders.
!
Reference ranges may differ by device, age, sex and population.
!
A small one-day change may reflect water rather than fat or muscle.
!
Results from different brands or devices may not be directly comparable.
!
Extreme body composition or altered hydration can reduce accuracy.
Medical interpretation matters
The report is combined with waist circumference, strength or function, physical examination, blood tests and your overall clinical situation when further evaluation is needed.
Tracking Progress Over Time
Use trends to improve your weight-management or strength plan.
Nutrition Adjustment
Review calorie intake, protein, fibre and meal structure when fat or muscle trends are not as expected.
Resistance Training
Use muscle trends to support a safer strength and activity plan.
Medication Monitoring
Add composition change to appetite, weight, side effects and metabolic response.
Hydration Consistency
Repeat unusual results when fluid status or testing conditions may have changed.
Goal Refinement
Shift the focus from a target weight to fat loss, muscle preservation and health improvement.
Planned Reassessment
Repeat at an interval appropriate for your program rather than testing too frequently.

FAQ
Body composition analysis questions, answered.
Testing procedures and available report values depend on the analyser used by the clinic. Preparation and interpretation are confirmed at your visit.
Body composition analysis estimates how body weight is distributed across fat mass, fat-free mass, skeletal muscle and body water. Depending on the device, the report may also include segmental muscle balance and an estimate of visceral fat.
BMI uses only height and weight. Body composition analysis adds estimated fat, muscle and water information, which can provide more context when two people have a similar BMI but different proportions of muscle and fat.
The device passes a very small electrical signal through the body and measures impedance. Because water-rich lean tissue and fat tissue conduct the signal differently, the system uses those measurements with device algorithms to estimate body-composition values.
No. The test is non-invasive and is usually completed while standing barefoot and holding the device handles. Most people do not feel the low-level measurement signal.
Follow the clinic's instructions, keep hydration and meal timing consistent, avoid heavy exercise shortly before testing, use the restroom first and remove heavy accessories. Testing under similar conditions improves comparison between visits.
Yes. Recent food intake, hydration changes, alcohol, exercise, body temperature, menstruation and fluid retention can influence bioelectrical impedance estimates. Results are most useful when repeated under similar conditions.
Depending on the device, the report may include weight, BMI, body-fat percentage, fat mass, skeletal muscle mass, total body water, segmental lean analysis, visceral-fat estimate and suggested reference ranges.
No. It is an assessment tool and should not be used alone to diagnose obesity, sarcopenia, fluid disorders or metabolic disease. The doctor interprets the report alongside symptoms, examination, waist measurement, laboratory tests and medical history.
The interval depends on your goal and treatment plan. For progress tracking, the clinic may repeat the test after enough time has passed for a meaningful change and will try to use similar testing conditions.
Tell the clinic if you have an implanted electronic medical device, are pregnant, have significant swelling or fluid imbalance, or cannot stand safely. The team will confirm whether the device and testing method are appropriate.
