Information on Body Composition
Principle of body composition calculation
Body fat has low electric conductivity
The BF508 measures the body fat percentage by the Bioelectrical Impedance (BI) method. Muscles, blood vessels
and bones are body tissues with a high water content that conducts electricity easily. Body fat is tissue that has little
electric conductivity. The BF508 sends an extremely weak electrical current of 50 kHz and less than 500 A through
your body to determine the amount of fat tissue. This weak electrical current is not felt while operating the BF508.
In order for the scale to determine your body composition, it uses the electrical impedance, along with your height,
weight, age and gender information to generate results based on OMRON’s data of body composition.
Measures the whole body to avoid the influence of fluctuations
During the course of a day, the amount of water in the body tends to gradually shift to the lower limbs. This is why
there is a tendency for the legs and ankles to swell in the evening or at night. The ratio of water in the upper body
and lower body is different in the morning and evening, and this means that the electrical impedance of the body
also varies. Since the BF508 uses electrodes for both hands and feet to take measurements, it can reduce the
influence of these fluctuations on measurement results.
Recommended measurement times
Understanding the normal changes in your body fat percentage can help you in preventing or reducing obesity.
Being aware of the times when the body fat percentages shift within your own daily schedule will assist you in
obtaining an accurate trending of your body fat. It is recommended to use this unit in the same environment and
daily circumstances. (See chart)
Avoid Taking Measurements Under the Following Conditions:
- Immediately after vigorous exercise, after a bath or sauna.
- After drinking alcohol or a large amount of water, after a meal (about 2 hours).
If a measurement is taken under these physical conditions, the calculated body composition may differ significantly
from the actual one because the water content in the body is changing.

Information on Body Composition
What is BMI (Body Mass Index)?
BMI uses the following simple formula to indicate the ratio between weight and height of a person.
BMI = weight (kg) / height (m) / height (m)
The OMRON BF508 uses the height information stored in your personal profile number or when entering
information in the Guest Mode to calculate your BMI classification.
If the fat level revealed by BMI is higher than the international standard, there is an increased likelihood of common
diseases. However, not all types of fat can be revealed by BMI.
What is Body Fat Percentage?
Body fat percentage refers to the amount of body fat mass in regards to the total body weight expressed as a
percentage.
Body fat percentage (%) = {Body fat mass (kg) / Body weight (kg)} × 100
The BF508 uses the BI method to estimate your body fat percentage.
Depending on where the fat is distributed in the body, it is classified as visceral fat or subcutaneous fat.
What is Visceral Fat Level?
Visceral fat = fat surrounding internal organs
Too much visceral fat is thought to be closely linked to increased levels of fat in the
bloodstream, which can lead to common diseases such as hyperlipidemia and
diabetes, which impairs the ability of insulin to transfer energy from the bloodstream
and using it in cells. In order to prevent or improve conditions of common diseases,
it is important to try and reduce visceral fat levels to an acceptable level. People
with high visceral fat levels tend to have large stomachs. However, this is not
always the case and high visceral fat levels can lead to metabolic obesity. Metabolic
obesity (visceral obesity with normal weight) represents fat levels that are higher
than average, even if a person’s weight is at or below the standard for their height.
What is Subcutaneous Fat?
Subcutaneous fat = fat below the skin
Subcutaneous fat not only accumulates around the stomach but also around the
upper arms, hips and thighs, and can cause a distortion of the body’s proportions.
Although not directly linked to increased risk of disease, it is thought to increase
pressure on the heart and other complications. Subcutaneous fat is not displayed in
this unit, but is included in the body fat percentage.
The reason calculated results may differ from actual body fat percentage
The body fat percentage measured by this unit may significantly differ from the actual body fat percentage in
the following situations:
Elderly people (over 81 years old) / People with a fever / Body builders or highly trained athletes /
Patients undergoing dialysis / Patients with osteoporosis who have very low bone density / Pregnant women /
People with swelling
These differences may be related to changing ratios of body fluid and/or body composition.

Informations sur la composition corporelle
Principe du calcul de la composition corporelle
La graisse corporelle a une faible conductivité électrique
L’unité BF508 détermine le pourcentage de graisse corporelle par la méthode de mesure de l’impédance bioélec-
trique (IB). Les muscles, les vaisseaux sanguins et les os sont des tissus corporels contenant une grande quantité
d’eau et qui sont bons conducteurs d’électricité. La graisse corporelle est un tissu dont la conductivité électrique est
faible. L’unité BF508 envoie un courant électrique extrêmement faible de 50 kHz et inférieur à 500 A dans votre
corps afin de déterminer la quantité de tissu graisseux. Vous ne ressentirez pas ce faible courant électrique lorsque
vous utiliserez l’unité BF508.
Pour déterminer la composition corporelle, la balance utilise l’impédance électrique ainsi que vos informations de
taille, poids, âge et sexe pour générer des résultats basés sur les données OMRON relatives à la composition cor-
porelle.
Mesure la totalité du corps pour éviter l’influence des fluctuations
Au cours de la journée, la quantité d’eau dans le corps tend à se déplacer graduellement vers les membres infé-
rieurs. C’est pourquoi les jambes et les chevilles ont tendance à enfler le soir ou la nuit. La proportion d’eau dans
les parties supérieure et inférieure du corps est différente le matin et le soir, ce qui signifie que l’impédance élec-
trique du corps varie également. Les mesures s’effectuant à l’aide d’électrodes placées au niveau des mains et
des pieds, l’unité BF508 réduit l’influence de ces fluctuations sur les résultats des mesures.
Périodes recommandées pour les mesures
Comprendre les changements normaux de votre pourcentage de graisse corporelle vous aidera à prévenir ou à
réduire l’obésité. Connaître les périodes où le pourcentage de graisse corporelle évolue dans votre activité quoti-
dienne vous permettra de suivre avec précision l’évolution de votre graisse corporelle. Il est recommandé d’utiliser
cette unité dans le même environnement et les mêmes conditions quotidiennes. (Voir le tableau)
Évitez de réaliser des mesures dans les conditions suivantes :
- Immédiatement après un exercice énergique, après un bain ou un sauna.
- Après avoir consommé de l’alcool ou bu une grande quantité d’eau, après un repas (environ 2 heures).
Si une mesure est réalisée dans les conditions ci-dessus, la composition corporelle calculée pourrait différer consi-
dérablement de la valeur réelle en raison de la modification de la quantité d’eau contenue dans le corps.

Informations sur la composition corporelle
Qu’est-ce que l’IMC (indice de masse corporelle) ?
L’IMC utilise la formule simple suivante pour indiquer le rapport entre le poids et la taille d’une personne.
IMC = poids (kg) / taille (m) / taille (m)
L’unité OMRON BF508 utilise les informations relatives à la taille qui sont stockées dans votre numéro de profil
personnel ou lors de la saisie d’informations en mode Invité afin de calculer votre classification IMC.
Si le niveau de graisse révélé par l’IMC est supérieur à celui recommandé par la norme internationale, la probabi-
lité que vous contractiez des maladies communes est plus élevée. L’IMC ne révèle toutefois pas tous les types de
graisse.
Qu’est-ce que le pourcentage de graisse corporelle ?
Le pourcentage de graisse corporelle est la quantité de masse graisseuse corporelle rapportée au poids corporel
total, exprimée sous forme de pourcentage.
Pourcentage de graisse corporelle (%) =
{masse graisseuse corporelle (kg) / poids corporel (kg)} × 100
Le BF508 utilise la méthode IB pour estimer votre pourcentage de graisse corporelle.
Selon les endroits où elle se loge dans le corps, la graisse est classée comme graisse viscérale ou graisse sous-
cutanée.
Qu’est-ce que le niveau de graisse viscérale ?
Graisse viscérale = graisse entourant les organes internes
On estime qu’une trop grande quantité de graisse viscérale est étroitement liée à
l’augmentation des niveaux de graisse dans le flux sanguin, qui peut être cause de
maladies communes telles que l’hyperlipidémie et le diabète, qui affectent la capa-
cité de l’insuline à transférer l’énergie depuis le flux sanguin et à l’utiliser dans les
cellules. Pour prévenir ces risques ou améliorer la condition des personnes
atteintes de ces maladies, il est important de réduire à un niveau acceptable les
niveaux de graisse viscérale. Les personnes présentant des niveaux élevés de
graisse viscérale ont souvent un ventre proéminent. Ceci n’est toutefois pas tou-
jours le cas et des niveaux élevés de graisse viscérale peuvent donner naissance à
une obésité métabolique. L’obésité métabolique (obésité viscérale avec un poids
normal) correspond à des niveaux de graisse plus élevés que la moyenne, même si
le poids d’une personne est inférieur ou égal au poids normal pour sa taille.
Qu’est-ce que la graisse sous-cutanée ?
Graisse sous-cutanée = graisse située sous la peau
La graisse sous-cutanée ne s’accumule pas seulement autour de l’estomac, mais
aussi au niveau des bras, des hanches et des cuisses, altérant les proportions du
corps. Bien qu’elle ne soit pas directement liée à une augmentation du risque de
maladie, on considère qu’elle augmente la pression sur le cœur et est source
d’autres complications. La graisse sous-cutanée n’est pas affichée par cette unité,
mais est incluse dans le pourcentage de graisse corporelle.
Raison pour laquelle les résultats calculés peuvent différer du pourcentage de
graisse corporelle réelle
Le pourcentage de graisse corporelle mesuré par cette unité peut différer fortement du pourcentage de graisse
corporelle réel dans les cas suivants :
Personnes âgées (plus de 81 ans) / Personnes ayant de la fièvre / Culturistes ou athlètes de haut niveau /
Patients subissant une dialyse / Patients souffrant d’ostéoporose ayant une très faible densité osseuse /
Femmes enceintes / Personnes présentant des œdèmes
Ces différences peuvent être liées à des changements des rapports entre le liquide corporel et/ou la composi-
tion corporelle.
