ABSI stands for A Body Shape Index. It combines waist circumference, height and weight to estimate health risks associated with abdominal fat distribution.

How is ABSI calculated?

ABSI is calculated using waist circumference, height and body weight. The formula adjusts waist size relative to body size to better assess health risk.

Is ABSI better than BMI?

ABSI provides additional information because it includes waist circumference, helping identify abdominal obesity and visceral fat risk that BMI may miss.

What does ABSI measure?

ABSI measures body shape and fat distribution, particularly abdominal fat, which is strongly associated with cardiovascular disease and metabolic disorders.

What is a healthy ABSI score?

A normal or good ABSI score is generally between 0.07 and 0.083. Values below this range suggest low health risk, while higher values (above ~0.085) may indicate increasing abdominal fat-related health risk.

Can ABSI estimate visceral fat?

ABSI is closely linked to abdominal fat distribution and can help identify people with elevated visceral fat-related health risks.

Why is waist circumference important?

Waist circumference is one of the strongest indicators of abdominal obesity and is associated with increased risk of diabetes, heart disease and premature mortality.

Can athletes have a healthy ABSI but a high BMI?

Yes. Athletes often have greater muscle mass which raises BMI, while maintaining a healthy waist circumference and ABSI score.

Should ABSI replace BMI?

ABSI is best used alongside BMI, body fat percentage and waist-to-height ratio to provide a more complete picture of health and body composition.

Can I lower my ABSI score?

Reducing abdominal fat through a calorie deficit, strength training, regular exercise and healthy nutrition may improve your ABSI score over time.

What is ABSI?

ABSI (A Body Shape Index) measures how much abdominal fat you carry relative to your height and weight.

Unlike BMI, ABSI focuses on waist circumference, which is a stronger predictor of health risks like heart disease and diabetes.

ABSI Formula Explained

1. Calculate BMI = weight / height²
2. Convert waist to meters
3. Apply ABSI = waist / (BMI^(2/3) × height^(1/2))

Why ABSI is important for health risk assessment

Research shows that waist circumference is a stronger predictor of health risks than weight alone. ABSI helps identify hidden risk in people with normal BMI but high abdominal fat.

Better prediction of cardiovascular risk than BMI alone
Focuses on visceral fat distribution
Useful for long-term health screening
