Body Composition Scan & Muscle Mass

You cannot change what you don't measure. A body composition scan shows you what the scale cannot.

The number on the scale tells you your total body weight, but it doesn't tell you what that weight is made of.

You can have the same weight while gaining body fat, losing muscle, or experiencing changes in body water. This becomes especially relevant during perimenopause and menopause, when changes in hormones, activity, sleep, and metabolism can affect body composition.

A body composition scan provides a more detailed look at your muscle mass, body fat, visceral fat, and other measurements that can help put changes in your body into context.

The goal isn't to focus on a number. It's to understand what's changing so your nutrition, exercise, and overall health plan can be based on useful information rather than weight alone.


What the InBody Scan Measures—and Why Each Metric Matters

Total and Segmental Muscle Mass

The scan estimates your lean mass throughout your body, including your arms, legs, and trunk.

Tracking muscle mass over time can help you understand whether your exercise and nutrition plan is supporting muscle maintenance and strength as your body changes.

How Much of Your Body Is Fat

Body fat percentage provides information that body weight and BMI cannot provide on their own.

Tracking changes in body fat can help show whether changes in weight are coming primarily from fat, lean tissue, or a combination of both.

Fat Around the Abdominal Organs

Visceral fat is stored around the internal organs and is associated with metabolic health risks when present in excess.

Understanding changes in visceral fat can provide another useful measure when evaluating body composition and metabolic health.

Estimated Energy Needs at Rest

Basal metabolic rate, or BMR, estimates the amount of energy your body uses at rest.

BMR is influenced by several factors, including body size, age, sex, and lean body mass. It can provide useful context when developing a nutrition or fitness plan, but it is an estimate rather than a direct measurement of your daily calorie needs.

Total Body Water and Fluid Distribution

The scan also provides estimates related to body water and fluid distribution.

These measurements can add context when reviewing changes in body composition over time, although they should always be interpreted alongside your overall health and clinical picture.


Why this is essential during perimenopause and menopause

Hormonal changes during perimenopause and menopause can be accompanied by changes in muscle mass, fat distribution, and body composition.

Age, physical activity, nutrition, sleep, genetics, and hormonal changes can all influence how your body changes during this stage of life.

Maintaining muscle becomes particularly important as you get older. Resistance training, adequate protein intake, appropriate nutrition, and other healthy lifestyle habits can all support muscle health.

A body composition scan gives you a baseline that can be repeated over time. Instead of relying only on the scale or how your clothes fit, you can track changes in muscle mass and body fat and use that information to guide your plan.


Frequently asked questions

Why is body composition more important than weight?
Weight measures total body mass. It does not distinguish between muscle, fat, bone, and body water.

Two people can have the same weight and very different body compositions. Even within the same person, weight can remain relatively stable while muscle mass and body fat change.

Body composition analysis provides additional information that can help you understand those changes.

What is visceral fat and why does it matter?

Visceral fat is fat stored within the abdominal cavity around internal organs.

Higher levels of visceral fat are associated with an increased risk of metabolic conditions, including insulin resistance and cardiovascular disease. Tracking visceral fat can therefore provide useful information about changes in body composition and metabolic health.

A scan result is only one part of the picture and should be interpreted alongside other health measurements.

Does menopause cause muscle loss?

Muscle mass can change during midlife and later adulthood, and hormonal changes during menopause may contribute to changes in body composition.

However, muscle loss is influenced by more than hormones. Age, physical activity, protein intake, nutrition, illness, and other lifestyle factors also matter.

Resistance training and adequate nutrition are important tools for maintaining muscle as you age. Your individual health plan can take these factors into account.

How does hormone therapy affect body composition?

Hormone therapy may influence body composition in some women, but it should not be viewed as a weight-loss or muscle-building treatment on its own.

Maintaining muscle and managing changes in body fat typically involves several factors, including resistance exercise, adequate protein, nutrition, sleep, and overall health.

For women using hormone therapy, body composition measurements can provide additional information to discuss with their healthcare provider over time.

What does the InBody scan involve?

The InBody scanner uses bioelectrical impedance analysis (BIA) to estimate body composition.

The process is noninvasive and takes only a few minutes. The resulting report can provide estimates of body fat, lean mass, visceral fat, body water, and other measurements.

Results can vary based on factors such as hydration, food intake, exercise, and other conditions. For this reason, following consistent testing conditions can make measurements easier to compare over time.
