Information on Body Composition
What is BMI?
Body Mass I ndex (BMI) is a simple index of weight-for -
height that is commonly used to classify under weight,
overweight and obesity in adults. BMI uses the following
simple formula to indicate the ratio between w eight and
height of a person.
BMI = weight(k g)
height(m) * height(m)
If the fat level revealed by BMI is higher than the interna-
tional standard, there is an increased likelihood of com-
mon diseases. However , not all types of fat can be re-
vealed by BMI.
BMI Designation by the WHO
Below 18.5 Under weight
18.5 – 24.9 Normal weight
25.0 – 29.9 Pr e- obesit y
30.0 – 34.9 Obesity class I
35.0 – 39.9 Obesity class II
Above 40 Obesity class III
The abov e index ref ers to the values for obesity judgment
proposed by WHO( W orld Health Organization).
What is Body F at Perc entage?
The body fat content is shown as the amount of stor ed fat
as a percentage of total body w eight. Ther e is no generally
accepted set value as this varies signicantly according t o
gender (due to the di erent build) and age.
Body fat is vital for basic body functions. I t ’ s protecting
organs, cushioning joints, regulating body temperature ,
storing vitamins and ser ves the body as energy storage .
As essential f or women a minimum body fat proportion
between 10% and 13% and for men between 10% and
13% is requested with the ex ception of competitive ath-
letes.
Body fat is not a clear indicator for health. T oo high body
weight and a too high body fat proportion are linked to
the incidence of many civilization diseases such as diabe-
tes, car diovascular diseases, et c.
Lack of movement and impr oper nutrition ar e often the
prime course for these diseases. There is an obvious dir ect
relationship between overweight and lack of movement.

Body F at F luctuations in a Day
Hydration levels in the body may a ect body fat readings .
Readings are usually highest in the early wak ing hours,
since the body tends to be deh ydrated after a long night’ s
sleep. For the most accurate reading, a person should tak e
a body fat percentage readings at a consist ent time of day
under consistent conditions.
Besides this basic cycle of uc tuations in the daily body fat
readings, variations may be caused b y hydration chang-
es in the body due to eating, drink ing, menstruation, ill-
ness, exer cising, and bathing . Daily body fat readings ar e
unique to each person, and depend upon one ’ s lifestyle,
job and activities.
What is Basal Metabolic Rate (BMR)?
Regardless of your activity level, a minimum level of calor-
ic intak e is r equired to sustain the body ’ s everyday func-
tions.
Known as the resting metabolism, this indicates how
many calories you need to ingest in or der to provide
enough energy f or your body to function.
What is Visc eral F at?
Visceral fat is a type of body fat that ’ s stored within the
abdominal cavit y . I t ’ s located near se veral vital organs, in-
cluding the liver , stomach, and intestines . It can also build
up in the ar teries. I t is dier ent from fat found directly
underneath the sk in, which is referred to as subcutane-
ous fat. Visceral fat is sometimes referred to as “ active fat ”
because it can ac tively increase the risk of serious health
problems such as high cholester ol, heart disease and t ype
2 diabetes. In order to prevent or improve these condi-
tions, it is important to tr y to reduce the amount of vis-
ceral fat levels to an acceptable level .
