What is a body composition analysis?

Body composition analysis evaluates the different components that make up your total body weight. Instead of measuring weight alone, it can provide information about body fat, muscle mass, fat-free mass, visceral fat, body water, and other measurements.

What is a SECA body composition scan?

A SECA body composition scan uses medical bioelectrical impedance analysis (BIA) technology to estimate different components of the body, including fat and skeletal muscle.

How does a BIA body composition test work?

Bioelectrical impedance analysis sends a very low electrical current through the body. Because different tissues have different electrical properties, the system uses the measured impedance along with validated algorithms to estimate different body-composition parameters.

Does a SECA scan measure body fat percentage?

Yes. Body fat and body fat percentage are among the primary measurements available through SECA medical body composition analysis.

Can a SECA body composition analysis measure muscle mass?

SECA medical body composition analyzers can estimate skeletal muscle mass and provide information about muscle distribution.

Does SECA measure visceral fat?

Compatible SECA medical body composition systems can provide measurements related to visceral fat, helping provide additional insight beyond total body fat percentage.

Is a SECA body composition test the same as a DEXA scan?

No. SECA body composition analyzers use bioelectrical impedance analysis, while DEXA uses low-dose X-ray technology. Both can provide information about body composition, but DEXA can also measure bone mineral density. SECA BIA is not a bone-density test.

Is body composition more useful than BMI?

They provide different information. BMI is a convenient screening measurement based on height and weight, while body composition analysis provides additional information about components such as fat and muscle. Your healthcare provider can interpret both measurements within the context of your overall health.

Can body composition testing help with weight loss?

Body composition testing can help track changes in fat mass and muscle mass during a weight-management program. This can reveal progress that may not always be apparent from total body weight alone.

How often should I have a body composition scan?

The appropriate frequency depends on your goals and health plan. Your LifeStream Family Medicine provider can recommend a testing schedule that provides enough time to identify meaningful changes.

Can my body composition improve without losing weight?

Yes. It is possible to lose body fat while maintaining or gaining muscle, meaning your total weight may change very little even though your body composition has improved.

Why should I track muscle during weight loss?

Weight loss can involve changes in both fat and lean tissue. Tracking skeletal muscle mass provides additional information that may help you and your healthcare provider evaluate whether your weight-management approach is supporting muscle preservation.
