AjBW – Adjusted Body Weight Calculator

What is an adjusted body weight calculator?

The adjusted body weight (AjBW) calculator is a simple tool for estimating the adjusted body weight for overweight or obese individuals based on gender, height, and weight.

What is adjusted body weight?

Adjusted Body Weight (AjBW) is used in clinical practice, especially by dietitians and healthcare professionals, to calculate a person's nutritional needs. It is precious when dealing with patients who are overweight or obese.

Adjusted Body Weight (AjBW) is a modification of a person's actual body weight, which accounts for the differences in metabolic activity between adipose tissue (fat) and lean tissue (muscle). When calculating energy requirements, actual body weight may lead to overestimations[1], especially for individuals above their healthy Body Mass Index (BMI). Therefore, as a recommendation, AjBW is an alternative to body weight in certain situations.

We strive to make our calculator apps as accurate as possible, but they cannot replace a professional doctor. Our website provides information for informational purposes, and it's not medical advice. Please consult your healthcare provider before making any decisions based on the results provided by our tool.
