Chapter P, Problem 24E

Lean Body Weight in Males A person’s lean body weight $L$ is the amount that he or she would weigh if all body fat were marginally to disappear. One text ${}^3$ gives the “equation that practitioners can use most feasibly in the field to predict lean body weight in young males.” The equation is

$L=98.42+1.08W-4.14 A$

Here $L$ is the lean body weight in pounds, $W$ is the weight in pounds and $A$ is the abdominal circumference in inches. Find the approximate lean body weight of a young adult male who weighs $188$ pounds and has an abdominal circumference of $35$ inches. What is the weight of his body fat? What is his body fat percent?
