Product Description

Why choose a body composition monitor?

This Omron BF508 body composition monitor provides a full body analysis to help you reach your diet and fitness goals. Omron's range of body composition monitors can give you accurate and painless body weight and fat measurements. More than just a scale, a body composition monitor can help to keep you motivated as you track your diet or fitness progress or simply as you make basic changes to your lifestyle in order to eat right and exercise more.

While it is important to monitor your weight, there are other internal factors that give you a better idea of your overall health. Using its sensor technology, the BF508 Body Composition Monitor gives you a painless and accurate total body reading - body weight (in kilograms), body fat percentage and visceral fat percentage - to help you understand how efficiently your body is working and to help you reach your fitness and weight loss goals. Both simple to use and offering accurate results, the BF508 is the ideal fitness tool to use any time in the comfort of your own home.

Identifying normal body fat levels depending based on age and sex.
Chewing the fat - What you need to know?
What is body fat?

Our bodies need a certain amount of fat to function effectively, but too much fat can have a detrimental effect to your overall health. Studies have shown that a high level of fat in the body, in particular visceral fat, increases the risk of developing more serious health conditions such as high blood pressure, heart disease and diabetes. The level of body fat you should have will vary depending on age and sex; this chart indicates what level band you should be in depending on these factors.

A cross-section of the chest
What is visceral fat?

Visceral fat or "central obesity", is used to describe the fat that is located inside the peritoneal cavity - that is, your midsection around your waist. Rather than being located directly under the skin as subcutaneous fat, this "visceral fat" can be found in between your internal organs, many of which are situated in this cavity.

Studies have shown that there is a strong correlation between high levels of visceral fat and the risk of developing cardiovascular disease as well as other medical conditions. The BF508 Body Composition Monitor will give you a reading between 30 levels, to indicate your level of visceral fat; a normal reading would be between one and nine, with a reading higher than 15 being very high.

What is subcutaneous fat?

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 lead to other complications. The BF508 Body Composition Monitor does not display subcutaneous fat ideally, but it is included in the body fat percentage reading as a whole.

How can you reduce your body fat?

The ideal way to reduce your overall body fat percentage is to take regular exercise and eat healthily. Using a body composition monitor such as the BF508 will give you accurate results, so you can monitor your progress on a fitness regime - or simply keep a check on your general health.

Scientifically speaking

Body fat has low electricity conductivity. The BF508 Body Composition Monitor measures the body fat percentage by using the Bioelectrical Impedance (BI) method. Muscles, blood vessels and bones are body tissues with higher 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 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 body composition, it uses the electrical impedance, along with your height, weight, age and gender information, to generate results based on pre-determined data of body composition.

Benefits of body composition monitors

Owning an Omron BF508 Body Composition Monitor is an easy and practical way to monitor your health at home. Using an Omron means reliability and accuracy - whenever you need it - from one of the world's leading healthcare-at-home provider.

    Very happy with these scales (apart from the fact they tell me I'm overweight and too fat!!)
    I got these to help monitor and motivate myself during a period of weight loss. They are doing just that, giving accurate and consistent readings for Weight, Bodyfat%, Viseral fat% and BMI. I then transfer them to a database program (Excel) and can produce graphs from there. (Sad I know but it helps me!)
    The downside has been mentioned in previous reviews:- that there's no measurement in Stones and pounds but I knew that before I purchased and whilst its nice to know the Stones and pounds, Kgs make graphs easier (base 10 instead of base 14) and to be honest its about time I converted.
    It would be nice to have the figures load direct to a computer (Wi Fi or otherwise) but its no great problem and for the money couldn't really be expected.
    A great set of bathroom scales that function brilliantly, looks stylish and doesn't cost an arm and a leg (which I may end up chopping off to reach my target weight)

    Over the years, Omron have built up their name as one of the leading manufacturers of electrical heath equipment. Their new body composition monitor comprising of a set of electrical bathroom scales and body fat monitor, allows for a simple day-to-day check of your current body mass.

    The instruction manual is incredibly easy to follow, with a simple step-by-step guide showing you how to use the monitor and then interpret the results. The guide takes the user through the importance of tracking and controlling your Body Mass Index (BMI), as well as your body fat percentage and visceral fat level. Your results can then be applied to the simple charts included within the guide, allowing you to clearly interpret your results in comparison to what is classed as `normal' for your body type. As daunting as these figures sound, it only takes a second to locate where you are on the various tables. Alas, my first results weren't too good!

    The various figures are calculated by cleverly measuring the electrical resistance between your feet and your hands. The results are then displayed to the user as their BMI reading, their visceral fat level (the fat surrounding your internal organs) and their overall body fat percentage. To allow for quick day-to-day use, the scales can store the necessary body type information (i.e. sex, height and age) for up to five users. This means that this info does not need to be inserted each time the user uses the equipment. The scales also have a `guest' function, for when a non-saved-user wishes to find out their statistics.

    The scales themselves are predominately constructed from a very solid plastic, allowing for a very sturdy and durable outer-casing.

    I bought these scales as I am going on a new fitness regime and want to get more information about my body than just a simple weight measurement, and the idea of getting your BMI and fat measurements really appeals to me.
    These scales are of solid construction and the readout is nice and clear. The handle unit is a good idea as it makes it easy to read the display as well as it having the sensors in it for the body fat measurements.
    The body fat analysis is basically an electrical resistance measurement between your hands and your feet, the more resistance, the more fat you are carrying. It then uses this measurement to effectively estimate your your subcutaneous and visceral fat percentages. Your BMI is also available, which is done by simple calculation of your details which you input (height, age, gender) and then it adds the weight and outputs your BMI in the usual fashion. The instruction manual contains simple tables which can be used to interpret the data the machine outputs for those who are unaware of the relevant numbers.
    The unit has a five person memory so that once you have input your gender, height, and age it will store them under a number (1-5) which you just select before you weigh yourself each time. You can also use the unit as a simple scale so you do not have to have the fat/BMI measurements if you do not want them.

    The downside to these scales is that they only weigh in kilos (to the nearest 100 grams) or pounds which means if you are a fan of stones and pounds as most dieters are then you will have to get a conversion table or just use the pounds and calculate your weight from there. This is a little bit of a hassle that I think has lost this product an extra star for me in my own rating.

    I have had this product for over 2 years and can honestly say I am very happy with it. Out of curiosity I decided to look at the 1 and 2 star reviews as I was surprised that people would rate it so low. As expected most have been left by people who don't really know how to use the scales (or any scales) properly.

    The majority of negative reviews are about the difference in readings the scales give if you weigh yourself repeatedly within a very short time period such as a few minutes. This is quite normal for any scales and is not a fault.

    If you read the negative reviews for all the scales on Amazon, you will see that the majority of complaints are for the very same reason. This is because there are a many contributing factors that will vary your reading every time you get on scales. The two main factors are your balance (no matter how still you think you are) and standing in the exact same spot on the scale.

    If you want to test your scales put an inanimate object on them in the exact same place and you will see the reading will be the same. We are humans and we move, even when we are trying to be as still as possible.

    As far as I am aware there are no 100% accurate scales on the market, and you will have this issue with every scales no matter how accurate they claim to be. I would question any manufacturer who claim their product is 100% accurate. These scales are manufactured by one of the leading manufacturers in hospital weighing equipment and as such are highly regarded by the medical industry.

    If you want to get an accurate reading as possible - weigh only once a week before you take a bath or shower as moisture (believe it or not) will greatly vary your reading and before you eat, I usually weigh on a Sunday morning.
