How to Get the Most Accurate and Reliable Body Composition Results

If you’ve ever wondered how to get the most accurate body composition results, or how to ensure your Evolt 360 scan delivers consistent, reliable and repeatable data, the secret lies in how and when you scan. Small differences in hydration, food intake, or exercise timing can affect results, which is why consistency in scanning matters just as much as the technology itself.

When it comes to measuring health, the number on the scale only tells part of the story. To truly understand your progress, body composition data from the Evolt 360 provides the full picture by showing how much of your body is made up of fat, muscle, and water.

Not all measurements are created equally. To make your data meaningful, it must be reliable and repeatable. The key to seeing true progress isn’t just scanning once; it’s scanning consistently under the same conditions, using trusted technology, like the Evolt 360 scanner, that tracks your internal changes over time.

Devices like the Evolt 360 Body Health Analyzer use advanced bioelectrical impedance technology to provide detailed readings of body composition, helping users see how training, nutrition, and recovery strategies are influencing results.

Below are the most important metrics to track and how to ensure you’re getting the most accurate and consistent data each time you scan.

Skeletal Muscle Mass (SMM)

Why it matters: A key indicator of strength, performance, metabolic rate, and long-term health.
How to get reliable data: Scan under the same conditions such as hydration, time of day, and nutrition to monitor true muscle change, not day-to-day fluctuations.

Segmental Muscle Mass (Arms, Legs, Trunk)

Why it matters: Reveals muscle distribution and potential imbalances.
How to get reliable data: Maintain consistent scanning posture and electrode contact points to ensure repeatable segmental results.

Basal Metabolic Rate (BMR)

Why it matters: BMR is closely linked to lean mass. More muscle means more energy burned at rest.
How to get reliable data: Track changes in BMR over time using consistent scanning intervals such as monthly or quarterly.

Visceral Fat Rating

Why it matters: High visceral fat is associated with chronic disease risk and poor metabolic health.
How to get reliable data: Avoid large meals, exercise, or dehydration before scanning as these factors can influence readings.

Lean Body Mass (LBM)

Why it matters: Represents everything in your body except fat, including muscle, bone, organs, and water.
How to get reliable data: Scan in a fasted or similar-fed state to minimize variation in water retention and digestion.

Total Body Water (TBW)

Why it matters: Water plays a critical role in performance, recovery, and scan consistency.
How to get reliable data: Stay well-hydrated and maintain similar fluid intake patterns between scans to keep TBW readings stable.

Biological Age (Evolt Score)

Why it matters: Reflects your body’s functional age based on composition, not your chronological age.
How to get reliable data: Reassess regularly under consistent conditions to see meaningful trends over time.

Why Reliability and Repeatability Matter

Meaningful progress starts with reliable and repeatable data. Each Evolt 360 scan provides a comparable snapshot when performed under similar conditions, allowing you to see the real effects of your training and nutrition.

Consistency builds confidence. When your data is repeatable, you can trust that every improvement you see represents genuine progress, not daily variability.

Body composition tracking isn’t about chasing a number on the scale. It’s about building a reliable system that measures what truly matters: strength, vitality, and longevity.
