8 Best Free Online ABSI Calculator Websites

Here is a list of best free online ABSI calculator websites. ABSI or A Body Shape Index is a metric that helps users assess the health risks associated with body shapes. ABSI is a more accurate indicator to assess the health risks associated with obesity compared to traditional Body Mass Index (BMI). Using the obtained ABSI value of a person, users can determine his/her mortality risk category. If you also want to calculate the ABSI value of a person, then check out these online ABSI calculator websites.

Through these websites, users can quickly calculate the ABSI of a person using five main parameters namely Height, Weight, Waist Circumference, Age, and Gender. Some calculators can also find out the BMI, ABSI z-score, BMI z-score, etc., values using the same set of input parameters. Based on the obtained ABSI value, these websites determine and show the health risk factors. Some websites also generate risk factor graphs highlighting the change in risk factors based on different age and weight values. To help new users, I have included the necessary calculation steps in the description of each website.

These websites offer multiple related calculators like Calorie Deficit Calculator, TDEE Calculator for All Ages, Body Fat Calculator, Macro Calculator, New BMI, and more. Go through the list to learn more about these websites.

Frequently Asked Questions

What does ABSI Z score mean?

ABSI Z score stands for Adjusted Body Shape Index Z score. It's a measure of your body fat distribution, specifically focusing on abdominal fat, and takes into account both your waist circumference and your overall body size (height and weight). It's an improvement over the popular BMI (Body Mass Index) because it can distinguish between people with similar BMIs but different fat distributions.

What does ABSI stand for?

ABSI stands for A Body Shape Index. It's a metric used to assess the health implications of a person's body shape by taking into account their height, weight, and waist circumference. It aims to be a more specific indicator of health risks associated with abdominal fat compared to the widely used BMI (Body Mass Index).

What are the advantages of body shape index?

ABSI specifically considers your waist circumference in relation to your height and weight, providing a more accurate picture of abdominal fat distribution. This is important because excess abdominal fat, or visceral fat, is linked to a higher risk of various health problems like heart disease, diabetes, and certain cancers, compared to fat stored elsewhere in the body.

Which body shape is the healthiest?

The idea of a single "healthiest" body shape is outdated and misleading. Focusing solely on body shape as a marker of health can be harmful, promoting body shaming and neglecting individual differences in genetics, lifestyle, and overall health.

What is absolute z-score?

This refers to the magnitude of a z-score without regard to its sign. Mathematically, it's obtained by taking the absolute value of the calculated z-score. For example, if your z-score is -2.5, its absolute value would be 2.5. The absolute value of a z-score tells you how far away a data point is from the mean in units of standard deviations, regardless of its direction (above or below). Higher absolute values indicate greater distance from the mean.
