Explanation: This formula uses logarithmic transformations of body measurements to estimate body fat percentage based on the relationship between circumference measurements and body composition.
Details: Monitoring body fat percentage is crucial for assessing health risks, tracking fitness progress, and developing appropriate nutrition and exercise plans. High body fat percentage is associated with increased risk of various health conditions.
Tips: Enter accurate measurements in inches. Measure abdomen at the level of the navel and neck just below the larynx. All values must be valid (measurements > 0, abdomen > neck).

A: Take measurements in the morning before eating or drinking, and ensure the tape measure is snug but not compressing the skin.
Q4: Are there limitations to this calculation method?
A: This method provides an estimate and may not be as accurate as DEXA scans or hydrostatic weighing. Results can vary based on measurement technique.
Q5: How often should I measure my body fat?
