Product Description

The Omron Fat Loss Monitor with Scale (HBF-400) provides three key health indicators: weight, body fat percentage and BMI. It does this by using reliable foot-to-foot bioelectrical impedance so all you have to do is align your feet on the metal sensors for a quick, accurate reading. It’s a perfect way to track your weight loss goals.

The Omron HBF-400 Fat Loss Monitor with Scale is the perfect way to track your weight loss goals, thanks to its fast, accurate measurement of weight, body fat percentage, and body mass index (BMI). Just step on the HBF-400 and in seconds you'll have much of the information that's vital to any

Simple controls and a large, easy-to-read display make fat and weight monitoring a snap. View larger.

Just step on and see your data in seconds.
weight loss or weight maintenance program.

For the Whole Family
The HBF-400 supports up to four personal profiles, so each member of your family can track their own measurements independently. Plus, an easy-to-read and large digital display makes it a snap to get the information you need.

Detailed Measurement
The weight display measures weight up to 330 pounds in .2-pound increments, while body fat percentage can be measured from 5 to 60 percent in .1 percent increments.

One of the keys to weight loss and management is tracking your body mass index, or BMI. The HBF-400 rates your BMI from 7.0 to 90.0 in .1 increments. BMI is classified at three levels: underweight, normal, overweight, and obese.

Made for Just about Everyone
The HBF-400 is set up to provide measurements for folks of nearly all heights (3'4" to 6' 6-3/4") and nearly all ages (10 to 79 years). Measurements are customized for males and females, as well.

Power and Dimensions
The HBF-400 runs on four AA batteries, and you can expect about a year of battery life when the device is used four times a day. The unit measures 12.2 x 11.8 x 2.1 inches (L x W x H). The unit weighs 4.7 pounds.

What's in the Box
HBF-400 unit, 4 AA batteries, and instruction manual.

Q&A - Fitness Monitors
What is the Bioelectrical Impedance Method?
Bioelectrical Impedance (BI) is considered one of the most accurate and accessible methods of screening body fat. Muscles, blood vessels and bones are body tissues having a high water content that conduct electricity easily. Body fat is tissue that has little electric conductivity. The monitor sends an extremely weak electrical current through your body to determine the amount of fat tissue. The weak electrical current is not felt while operating the Body Fat Analyzer. The monitor is calculated by a formula that includes five factors; electric resistance, height, weight, age and gender.
What is visceral fat?
Visceral fat is located around the organs. Too much visceral fat is thought to be closely linked to increased level of fat in the bloodstream, which can lead to common conditions such as high cholesterol, cardiovascular disease and diabetes. Sedentary life style causes excess visceral fat, and exercise can reduce it quicker than subcutaneous fat (fat located under skin).
What is resting metabolism?
Resting metabolism is the energy to maintain vital functions and it counts 60 to 70% of total energy consumption. Knowing your resting metabolism can help your dietplan. If you can increase daily activity while keeping food intake at resting metabolism level, you can lose weight.
What is skeletal muscle?
Skeletal muscle is muscle attached to the bones that is used to move the body. If you do weight loss without exercise, you may lose skeletal muscle. Skeletal muscle is important to maintain your resting metabolism as well as your functionality. Monitoring skeletal muscle during weight loss is key to avoid weight rebound in the future.

Recommended Usage

For optimum accuracy, use your body composition monitor right after you wake up and at least 2 hours after each meal.

Avoid taking measurements after exercising, drinking a large amount of water, or bathing. These may significantly alter your body composition readings.

Do not use this device if you are pregnant or have an implanted medical device or cardiac pacemaker. Consult your physician before beginning a weight reduction program.

The Omron Advantage

Bioelectrical impedance is clinically proven. It works by sending a small, imperceptible electrical signal through the whole body–from arm to arm or foot to foot–to calculate total body water.

Given the ratios of the water in your upper and lower body change throughout the day – as gravity pulls more water into your lower extremities – the electrical impedance of the body also varies.

Typically, these types of measurements could only be taken by a doctor or physical trainer. With Omron, you can get them at home, anytime you want.

Fitness Indicators

Body Weight

It may be an obvious fitness indicator, but body weight alone doesn’t tell you everything. Measuring your weight in conjunction with other readings gives you a clearer picture of what’s going on with your body.

Body Fat Percentage

If you’re losing weight, tracking your body fat percentage lets you know you’re trimming the fat as opposed to losing other kinds of weight.

Body Mass Index (BMI)

This indicator is calculated from your height and weight and is a measure of overall body fat. The higher the BMI, the greater the chance for possible health risks.

As a scale the Omron HBF-500 is excellent. It is consistent, in tests with my wife and I (who are more than 100 pounds different in weight) the scale gave the same weight each of 5 times in a row that we stepped on it. So it is consistent. I am a nurse and weighed myself on our calibrated scales and found that this scale weighed me 0.5 pounds heavier than the hospital one, which can be explained by the glass of water I drank when I got home. So it is both consistent and accurate.

So what about the body fat monitor: As to the accuracy of the monitor I cannot speak. However, it is very consistent, much more consistent than the experience that I have had with the handheld-only monitors from Omron. The scale will calculate your percent body fat & your percent skeletal muscle. It will also give you a reading of your visceral body fat, which is a better indicator of your health risk associated with body fat (visceral body fat is the fat which is inside your body surrounding your organs, which subcutaneous fat is the fat that we all see just under our skin). Using these calculations and the user-defined height, weight, and age data that you enter, it will give you your resting metabolic energy needs for the day to give you an idea of how much you should be eating to lose weight in a healthy manner.

The scale has 4 user profiles so that 4 different users can use the scale and track their data. Data can be recalled letting you know what your measurements were yesterday, a week ago, a month ago, and 3 months ago.

The handle fits well inside the front of the scale. I was expecting the scale to be bulkier than it is. It is just a little taller than a normal scale and very attractive. It isn't something that you're going to need to hide between uses.

I don't do reviews often, but this product (and/or a similar model) have taken some knocks that my experience contradicts.

First off, I think expectations need to be realistic if you are going to buy any kind of scale or monitor.
1) Weight: No two scales read the same. They may be darn close, but rarely the same. What should be expected is that the scale always reads the same weight over time. I have a dumbbell that says it's 10 lbs and I have seen three scales say it's anywhere from 9.5 to 10.3 lbs. So you can demand consistency, but realistically for most of us absolute accuracy is just not practical.

2) Body Fat or Composition: Unless you can find (and pay for) a DEXA (Dual Energy X-Ray) or Hydrostatic (full immersion weighing) test this number is totally subjective. A while back I had two physical therapist/trainers that work in a medical rehab/training facility check my composition using the calipers method ten minutes apart. The results were 29% and 34%. They were not surprised, said they were usually within 2%-3% of each other.

I don't want it to sound like I am lowering the bar here, just trying to be realistic.

So, what about the Omron HBF-500?
As for weight, my HBF-500 has said from day one that my "10lb" dumbbell is 9.6 lbs (it's mate is always 9.7). Who's right, Omron or Weider? No idea. So who cares if the scale is off by 4% or if that dumbbell is really 4% lighter than advertised? The fact is that is is consistent, and if it says that on the day I got it I weighed 296 and I now weight 275, it is that 26lb difference that is important.

Same thing for composition. I feel it is the change over time that is important, not the absolute accuracy. What I have found is that I have to be consistent in using the device.

My 15 year-old Health-o-Meter scale recently gave out. So, I did my homework and selected the HBF-400 as the best unit for the price. I'm very pleased with the results. (1) It's easy to use. Press the button, it callibrates itself, step on the scale, and it quickly gives a weight reading. Remarkably fast, considering how incidental body movement must affect accuracy. And it gives me an appreciation of why manufacturers callibrate their scales in two-tenth units. If they tried to specifiy accuracy down to the nearest tenth, it would take much longer for a person's body sway to dampen. (2) It's easy to read. The large numbers make reading it a snap. (3) It is an attractive unit. Well-crafted. Modern looking. Much nicer than its picture. (4) The body fat analyzer seems accurate. It matched exactly with the results I recently got at a health fair. Although I primarily purchased the HBF-400 as a better scale to track my diet, the fat analyzer is a nice motivational feature. It reassures me that, even when there is a slight weight rebound, my overall fat trend is proceeding in the right direction. (5) Lastly, the accuracy of the scale makes me appreciate why my body weight seems to fluctuate so much. With my old scale (plus or minus one pound readings), I couldn't figure out why I seemed to gain or lose a couple of pounds within the same day. With the Omron scale, I can see how drinking a glass of water, eating a meal, or going to the bathroom affects each reading. I gave this product a 5-star rating. It exceeded all of my expectations.


EDIT: 3 years later and the Omron HBF-400 is still working like a charm. It's survived the usual household treatment of being occasionally kicked around, especially by my six year old boy, and it still looks and works like brand new. Very happy with its quality and performance.
