Related to body fat: Body fat percentage
The percentage of a person’s body that is not composed of water, muscle, bone, and vital organs

bod·y fat

(bod'ē fat)
The percentage of adipose tissue compared with muscle estimated by underwater weighing, calculating the ratio of weight in kilograms to height in meters, and/or estimating bioelectrical impedance of the body.

body fat

The portion of the human body that consists of fat. This is estimated in several ways: by hydrodensitometry, by calculating the ratio of weight in kilograms to height in meters squared (Quetelet index), and more recently, by estimating bioelectrical impedance of the body. None of these methods provides a precise indicator of body composition, but bioelectrical impedance is the simplest, least expensive, and most nearly accurate.

body fat

normal healthy values usually quoted for total body fat are 15% (12-19%) of body mass for young men and 27% (25-30%) for women, both increasing by about 5% from late teens to sixties. essential fat in the tissues and organs (including bone marrow, nervous system and muscle) averages 3% body mass for men and 12% for women (extra related to reproductive function); it is not a labile energy reserve, but a vital component for normal structure and function. storage fat represents the energy reserve that accumulates as adipose tissue beneath the skin and in visceral depots, averaging 12% body mass for men and 15% body mass for women. Methods most commonly used for estimating percentage fat are: measurement of skinfold thickness at prescribed sites, body density measurement, and bio electrical impedance analysis.

Measuring Adiposity in Patients: Utility of Body Mass Index (BMI), Percent Body Fat, and Leptin PLoS ONE April 2nd, 2012 by Nirav R.
Table 3 shows the difference in percent body fat estimates from the three methods by body weight (BMI) categories.
These include bioelectrical impedance analysis (BIA), which uses an electrical current to estimate body fat.
The survey was commissioned by private healthcare provider Bupa which this month launched a pounds 149 Core Health Assessment which includes checks on BMI and body fat ratio.
The researchers divided the patients into five groups based on body fat percentage: less than 10% (34 patients); 10% to less than 20% (156 patients); 20% to less than 30% (210 patients), 30% to less than 40% (182 patients), and 40% or higher (89 patients).
How to measure body fat: |Body fat callipers are by far the easiest way is to measure your body fat.
Compared to the reduced-fat diet, the reduced-carb diet was particularly effective at lowering insulin secretion and increasing fat burning, resulting in significant body fat loss," says Kevin Hall, senior investigator and lead study author, "but interestingly, study participants lost even more body fat during the fat-restricted diet, as it resulted in a greater imbalance between the fat eaten and fat burned.
His model simulations showed that only the carb-restricted diet would lead to changes in the amount of fat burned by the body, whereas the reduced-fat diet would lead to greater overall body fat loss, but he needed the human data to back it up.
8) Higher body fat not only elevates the individual Soldier's health risk, but may also reduce Soldier combat readiness and physical performance; affects the Soldier's eligibility for command positions, promotion, and attendance at professional military schools; and/or may result in early separation from service.
A Brigham Young University researcher says consistent bedtimes and, more important, wakeup times have a bearing on body fat.
19 ( ANI ): A new study has found that women who go to sleep and woke up at same time every day had lower body fat.
