Objective. Many web-based calculators exist which calculate weight loss based on a change in daily energy intake. Likewise, many calculators are also available that calculate the required daily energy change to accomplish a desired weight change. We wanted to develop a calculator that would additionally accurately predict body weight and hip circumference measurement changes based on a desired waist circumference measurement change or goal.
Methods. Algorithms for the calculator were based on anthropometric body density equations and multiple regression equations of CDC U.S. population anthropometric data and developed using STELLA Professional software (iSeeSystems.com). We used the calculator to predict body weight and hip circumference measurements at four different time points using data from two published research studies that reported anthropometric measurements during a weight loss intervention. We compared actual measurements at each time point to the calculated measures and determined the % error for the calculated values.
Results. The average % error ranged from -1.0% to 1.9% and 1.1% to 1.7% for calculated body weight and hip circumference measurements, respectively.
Conclusions. This calculator may be used to calculate how body weight and hip circumference may be expected to change as waist circumference is reduced during weight loss.
