Track What Matters

Track your weight loss
progress with InBody

Are you actively tracking your weight loss progress? If you’re like most people, you probably step on your bathroom scale whenever you want to assess your health. However, doesn’t it often feel like your plans to get healthier don’t work out as you expected?

It can be frustrating when a new diet or exercise routine seems to only help you lose weight temporarily — and at times, you may even find yourself gaining back more weight than before. This pattern occurs because your bathroom scale can be misleading.

The InBody 580 shows you what your weight is actually made of — so you can make informed adjustments that lead to major long-term improvements.

Ditch The Scale

Weight loss isn’t the same as fat loss

As we age, we naturally lose dense muscle mass — so a lower number on the scale doesn’t always mean we’re healthier. The key to real fitness is losing excess body fat, not just body weight.

Can’t distinguish fat from muscle

Hides muscle loss as you age
Misses visceral fat changes
Can demoralize real progress

What InBody Measures

Six core body composition metrics

Your weight is made up of muscle, fat, bone, and water. InBody shows you the proportions — so you can make small adjustments that lead to major improvements.

Skeletal Muscle Mass

Total pounds of muscle in your body — the foundation of metabolism, strength, and healthy aging.

Percent Body Fat

The percentage of your body that’s fat tissue — a more meaningful metric than total weight alone.

Segmental Body Water

Water distribution across each body segment — helps identify fluid imbalances and hydration issues.

Visceral Fat Area

Deep abdominal fat surrounding your organs — a key driver of chronic disease risk that you can’t see in the mirror.

Cellular Health

Measured via Segmental Phase Angle — reveals the health and integrity of your cells at a foundational level.

Hydration Levels

Tracked via the BIVA Graph — gives you a clear picture of your overall hydration status and balance.

Segmental Analysis

Every limb. Every segment.

Most body composition tools give you one whole-body number. The InBody 580 measures each limb and your trunk separately — revealing imbalances and asymmetries you’d otherwise miss.

The InBody 580 performs segmental analysis, assessing each limb and your trunk to reveal its muscle mass, body fat, body water balance, and cellular health.

This gives you insight into:

Your current health status
Potential areas of inflammation
Your risk of chronic disease
Which exercise and nutrition plans will be most effective for you
What You’ll Learn

Insights you can actually act on

Armed with this data, you and your provider can make small adjustments that lead to major long-term improvements.

Recommended Cadence

Test every 2 to 4 weeks

For continuous monitoring of your progress toward fitness goals, we recommend taking an InBody test every 2 to 4 weeks. This cadence is frequent enough to see meaningful changes — but spaced enough to avoid noise from day-to-day fluctuations in water or food intake.

What is InBody? +
InBody is a body composition analysis system that uses bioelectrical impedance to measure the pounds of muscle, fat, bone, and water in your body. At Prestige Medical Group, we use the InBody 580 — which performs segmental analysis, assessing each limb and your trunk to reveal muscle mass, body fat, water balance, and cellular health.
Why is InBody better than a regular scale? +
A bathroom scale only tells you total weight — it can’t tell whether changes are coming from fat, muscle, or water. As we age, we naturally lose dense muscle mass, so a lower scale number doesn’t always mean better health. InBody shows you what your weight is actually made of, so you can see whether you’re losing fat or muscle and make informed adjustments.
What does InBody measure? +
The InBody 580 measures skeletal muscle mass, percent body fat, segmental body water, visceral fat area, cellular health (via segmental phase angle), and hydration levels (via the BIVA graph). It also performs segmental analysis, assessing each limb and the trunk individually.
What insights does InBody provide? +
InBody data reveals your current health status, potential areas of inflammation, your risk of chronic disease, and which exercise and nutrition plans will be most effective for you. Armed with this data, you can make small adjustments that lead to major long-term improvements.
How often should I take an InBody test? +
We recommend taking an InBody test every 2 to 4 weeks to continuously monitor your progress toward your fitness goals. This cadence is frequent enough to see meaningful changes — but spaced enough to avoid noise from day-to-day fluctuations.
How long does an InBody test take? +
The InBody test itself takes about 60 seconds. You stand on the device with bare feet and hold the handles while the analysis runs. Results are printed on a comprehensive Result Sheet and can also be tracked through the InBody App.
Is InBody part of the weight loss program? +
Yes. InBody body composition analysis is integrated into our medical weight loss program — including our $99 first-month Semaglutide special, which includes an InBody scan. Regular InBody testing is recommended throughout your weight loss journey to track real progress, not just scale numbers.
Can I track my InBody data over time? +
Yes. Each InBody test provides a Result Sheet printout, and you can also track your progress through the InBody App. The customizable Body Composition History feature lets you personalize which outputs are displayed and see how specific metrics — like Percent Body Fat — change over time.
