The advanced body composition analyser Tanita BC-613S uses bioelectrical impedance analysis (BIA) technology with 8 electrodes. This method relies on passing a very low-intensity electrical current through the body, which is imperceptible to the person being measured.

What it measures

Different body tissues, such as muscle mass and adipose tissue, present different resistance to the current. Based on this difference, the following are calculated segmentally:

• Body weight
• Body fat percentage
• Muscle mass
• Bone mass
• Body Mass Index (BMI)
• Daily caloric intake
• Metabolic age
• Total body water

How the measurement is done

The procedure is simple, non-invasive and takes only a few seconds. For accurate results, the person should:

• Fast for 3 hours before the measurement
• Not exercise on the day of the measurement, as total body water is affected
• Avoid alcohol in the previous 24 hours, as body hydration is affected
• Urinate beforehand
• Wear light clothing, ideally similar each time the measurement is repeated

Why we use it

• Personalised nutrition plan design
• Precise monitoring of body composition changes
• Segmental analysis by body region
• Tracking metabolic age and hydration

The skinfold caliper is a specialised measurement instrument used to estimate subcutaneous fat. It works by measuring skinfold thickness — the fold of skin together with the subcutaneous fat — at specific points on the body.

What it measures

The caliper measures the thickness of subcutaneous fat in selected areas, such as:

• Triceps
• Biceps
• Subscapular region
• Abdominal region
• Thigh
• Chest (in men)

These measurements are used to estimate total body fat percentage.

How the measurement is done

The measurement is performed by gently grasping the skin and subcutaneous fat with the fingers, creating a fold, onto which the caliper is applied.

Why we do it

• Estimating body fat percentage
• Monitoring body composition changes with greater precision

The tape measure is a simple yet highly useful body assessment tool, used to measure body circumferences. It is a fundamental part of nutritional monitoring, providing important information about body composition and fat distribution — specifically where fat is stored and for tracking muscle development.

What it measures

With the tape measure we record body circumferences, such as:

• Waist
• Hips
• Thighs (left and right)
• Upper arms (left and right)

How the measurement is done

The measurement is taken with the tape resting gently against the skin, without pressing. For reliable results:

• Measurements are taken at the exact same points each time
• The body is in a standing, relaxed position
• The same methodology is followed at every session

Why we do it

• Tracking body changes that don't always show on the scale
• Assessing fat distribution and muscle mass
• Evaluating health indicators, such as increased abdominal fat deposition
