[. . . ] The normal body fat level varies with age and, in particular, gender. The normal value for women is around 10% higher than for men. With increasing age the body breaks down muscle mass and this increases the body fat level. 7 Percentage ratio of body fat to total weight FEMALE Age Low fat level 6-12 13-19 20-39 40-59 60-79 Athlete <7 < 20 < 21 < 23 < 25 Normal fat level 7-19 20-31 21-32 23-34 25-36 12-25 High fat level 19-25 31-37 32-38 34-40 36-42 Very high fat level > 25 > 37 > 38 > 40 > 42 MALE Age Low fat level <7 <8 <9 < 11 < 13 Normal fat level 7-18 8-19 9-20 11-22 13-24 3-15 High fat level 18-25 19-25 20-26 22-28 24-30 Very high fat level > 25 > 25 > 26 > 28 > 30 6-12 13-19 20-39 40-59 60-79 Athlete Body water 60% of an adult's body is made up of water. This varies according to certain factors: older people have a lower water level than younger people, and men have a higher water level than women. The difference between men and women is based on women's higher body fat mass. As the majority of the body water is found in the fat-free mass (73% of the fat-free mass is water) and the water content of fat tissue is naturally very low (around 10% of fat tissue is water), when the body fat ratio is low the body water ratio falls automatically. A 5% loss of water can reduce body energy by 20­30%. Drink at least 2 liters of liquid every day. Normal percentage of body water Child Adult Athlete FEMALE 58-70 42-61 56-71 MALE 60-73 46-66 60-73 In general sports people have 5 % more body water. As age increases the water ratio falls by around 10 % 8 Muscle mass The muscle mass is the body's motor. The largest share of the energy we use is consumed by muscles. The muscles ensure that the body temperature is maintained and are the basis of our physical performance. Checking the muscle mass is particularly important for people with weight or fat problems. As the body needs muscles to remove excess energy reserves or fat deposits, weight reduction can only be successful in the long term if muscles are built up at the same time. Age 6 ­ 12 13 ­ 79 Athlete FEMALE Muscle Mass > 36 > 30 > 38 MALE Muscle Mass > 40 > 34 > 42 Athlete mode Your scales have a separate setting for very fit sports people or those with a lot of muscles ("athletes"). As muscle cells have a similar bio-electric resistance to fat cells the scales could interpret muscles as fat. This problem only occurs if the muscle mass is large; if a person has a normal range of muscles the scales do not measure this as fat. The athlete mode prevents this incorrect interpretation. In this mode the actual body fat values are measured using a different mathematical formula. 9 Causes of inaccurate measurement results The analysis is based on measuring electrical body resistance. Eating and drinking habits over the day and your personal lifestyle affect the level of water. This is noticeable from variations in the readouts. In order to achieve an analysis result that is as precise and repeatable as possible ensure that the measurement conditions are the same as this is the only way to observe changes over a longer period of time.
