The triceps skin fold is the width of a fold of skin taken over the triceps muscle. It is measured using skinfold calipers. (See body fat percentage#Skinfold methods for general information on skinfold fat measurements.) The measurement is taken at a standardized position (one of eight standard skinfold measurement points) at the midpoint of ...
In males, mean percentage body fat ranged from 23% at age 16–19 years to 31% at age 60–79 years. In females, mean percentage body fat ranged from 32% at age 8–11 years to 42% at age 60–79 years. But it is important to recognise that women need at least 9% more body fat than men to live a normal healthy life. [2]
A wide variety of body composition measurement methods exist. The gold standard measurement technique for the 4-compartment model consists of a weight measurement, body density measurement using hydrostatic weighing or air displacement plethysmography, total body water calculation using isotope dilution analysis, and mineral content measurement by dual-energy X-ray absorptiometry (DEXA).

In using human body and fat mass data from the United States National Health and Nutrition Examination Survey (NHANES) database, the Thomas group found that BRI never was a negative value, and that larger BRI values were associated with people having a round shape, while shape values closer to 1 were related to people with narrow, lean bodies.

The adult human body averages ~53% water. [7] This varies substantially by age, sex, and adiposity. In a large sample of adults of all ages and both sexes, the figure for water fraction by weight was found to be 48 ±6% for females and 58 ±8% water for males. [8]
The body-positive movement has encouraged people, especially women, to see beauty in all shapes and sizes, and it's reminded us that body ideals are culturally constructed and not based on science.
