Summarize the following:
Take all measurements with the tape flat against your skin, but not compressing it: Look straight ahead and relax your shoulders without hunching. Place the tape flat around your neck, just below the larynx (Adam's apple). Keep the tape level, at the same height on the front and back of the neck. Round the measurement up to the nearest half inch. For example, if your neck measures 14.6 inches, round up to 15 inches. Guide the measuring tape around the circumference of the waist at the most narrow point, usually between the belly button and the sternum. If you're not sure where this is, measure at several points and use the smallest value: For best results, hang your arms at your sides while someone else measures. Breathe in and exhale normally. Record the abdomen measurement at the end of the breath. Round down to the nearest half inch. For example, your abdomen might measure 28 inches around. Women may carry more body fat around their hips compared to men. Including this measurement is important for an accurate estimate of female body fat: You can measure against your skin or over thin clothing. If you are wearing tight clothing that compresses your soft tissue, change into something else and wait 30 minutes. Wrap the measuring tape around the hips so that it winds around the widest part of the buttocks, as viewed from the side. Keep the tape parallel to the floor. Record this measurement, rounding down to the nearest half inch. An example of your hip measurement might be 32 inches. Take height into account, since a taller woman has larger measurements than a shorter woman with the same proportions: Stand straight against a wall or other flat surface. Pull your shoulders back, keep your head up, and look straight ahead. Place a ruler or straight edge against the top of your head. Hold it flat and mark the wall with a pencil. Measure from the floor up to the pencil mark on the wall. Record the result in inches. For example, if you are 5'5", write down 65 inches. To avoid rounding errors, enter the following equation on one line of a calculator: Female body fat% =163.205log(waist+hipneck)97.684log(height)78.387{\displaystyle 163.205\log(waist+hip-neck)-97.684\log(height)-78.387} For instance, entering the example measurements above:Body fat% =163.205log(28+3215)97.684log(65)78.387{\displaystyle 163.205\log(28+32-15)-97.684\log(65)-78.387}=163.205log(45)97.684log(65)78.387{\displaystyle =163.205\log(45)-97.684\log(65)-78.387}=14.33{\displaystyle =14.33}This woman has approximately 14.33% body fat. This formula uses log10{\displaystyle log_{10}}, the default log button on calculators. Use these guidelines as a starting point to determine whether you are at a healthy body fat percentage: A body fat percentage above 33% (if under 40 years old) may be considered overweight, while 39% or higher puts you in the highest risk category. A typical healthy woman has a body fat percentage between 21 and 33% (2334% if over age 40, or 2436% if over 60). Female athletes typically have a body fat of 1420%, varying by sport. Women typically carry about 10-12% of essential body fat. Falling below this can be dangerous.
