How the Calculator Works
Step-by-Step Process
Enter Your Measurements
Provide your height, weight, waist circumference, and age
Calculate BMI
We first calculate your Body Mass Index using height and weight
Apply ABSI Formula
We use the formula: ABSI = Waist ÷ (BMI^(2/3) × Height^(1/2))
Generate Results
We compare your ABSI to population data and provide wellness insights
What Makes ABSI Different?
More Comprehensive
Unlike BMI, ABSI considers waist circumference for a complete body composition picture
Body Shape Focus
ABSI specifically looks at how your body fat is distributed, not just total weight
Wellness Insights
Provides actionable insights about your body composition patterns
The ABSI Formula Explained
ABSI = Waist Circumference ÷ (BMI^(2/3) × Height^(1/2))
This formula creates a ratio that accounts for your body size, shape, and composition
Understanding ABSI
What is ABSI?
ABSI (A Body Shape Index) is a wellness assessment tool that evaluates body composition by considering waist circumference relative to height and weight. It provides insights into health patterns and body shape characteristics.
Key Benefits:
- Wellness Focus: Provides insights into body composition patterns
- Comprehensive View: Considers multiple body measurements
- Health Awareness: Helps track wellness trends over time
How ABSI Works
ABSI combines your waist circumference, height, and weight to create a comprehensive wellness assessment. This approach provides a more complete picture of body composition than individual measurements alone.
Wellness Categories:
- • Very Low Risk: Excellent body composition patterns
- • Low Risk: Healthy body shape characteristics
- • Average Risk: Typical body composition patterns
- • High Risk: May benefit from lifestyle adjustments

- Generally associated with better body composition patterns
- May indicate lower abdominal fat accumulation
Higher ABSI Values (Areas for Improvement)
- Indicates a larger waist relative to your height and weight
- May suggest higher abdominal fat distribution
- Could benefit from lifestyle modifications
