InBody Muscle-Fat Analysis Bars: How to Read Them

The InBody Muscle-Fat Analysis is a three-bar chart (weight on top, skeletal muscle mass in the middle, body fat mass at the bottom), and you read it by comparing how far each bar stretches against a shaded normal band. A long middle bar with a shorter bottom bar is the pattern most training plans aim for. Your own set of bars comes with the free scan in a free consultation, and the notes below tell you what to look for in them.

How each bar is built

All three bars are plotted as a percentage of a reference for someone of your height and sex. The shaded normal band sits around the 100 percent mark on each. A bar ending inside the band is near the reference. A bar running past the band’s right edge is above it. A bar stopping short is below it.

• Weight. Your total scale weight. It is context, not a verdict, because it is the sum of the other two plus water, bone and organs.
• Skeletal muscle mass. The muscle attached to your skeleton, and the bar training is meant to lengthen.
• Body fat mass. Pounds of fat, which is the bar most people hope to shorten.

What common bar patterns suggest

Read the three together, using this if-this-then-that list:

• Weight long, muscle short, fat long. Heavy but under-muscled. The first priority is lifting and protein, not a harsher diet.
• Weight long, muscle long, fat near normal. A strong frame carrying plenty of muscle. Maintain, and watch fat mass drift.
• Weight near normal, muscle short, fat near or over normal. A normal scale reading hiding low muscle, often called normal-weight high body fat.
• All three short. A smaller frame. The goal is usually to build muscle gradually and eat enough to support it.

Each pattern is a starting hypothesis, never a diagnosis, and a coach will pair it with your training history and goals.

Reading the bars across two scans

Lay two printouts side by side and follow the middle and bottom bars. Good progress looks like the middle bar growing longer, the bottom bar shortening or holding, and the top bar doing whatever it likes. If the top bar shrank but the middle bar shrank with it, you lost muscle with the fat, a result the page on dropped scores helps you troubleshoot.

Because the bars all derive from the same water-sensitive reading, compare only scans taken under similar conditions. The matched-scan checklist lists them.

Where the letters fit in

The C, I and D labels are a shorthand for the same chart. If you want the vocabulary a coach uses in conversation, the shapes explained maps the letters back to the bars, and the broader InBody score page sums up the balance in one figure.

Your next step

Photograph the bars on each printout and keep them in a single album with dates. In four to six weeks, hold the new set against the old and compare only lengths, not impressions. Bring both to a coach and ask which bar your next block of training should move first.
