Omron's body fat monitor Topic


Hello everyone,

I am looking for the best "convenient to accurate" way to measure my body fat.
lot of people are talking about the Omron's body fat monitor. They say it's pretty much as accurate as body-fat pinchers.

I wanted to verify of anyone has tested it (or a similar Bioelectrical Impedance Method)


As far as I can telll Omron's are using bioelectrical impedance, which is _pretty_ inaccurate, because of factors like hydration and other things, but if you try and use it under the same circumstances every day, I find it gives you a good indication of how things are going :)


I have had to use Omron's handheld BIA for health fairs and I am NOT a big fan of it. I have repeatedly tested myself over the course of several hours during these fairs and my body fat % would vary wildly. I would not invest in one.

The BIA scales have better reliability/accuracy than the handheld devices.

If you can get tested with a Bod Pod in your area, that might be worth the extra cost. You can Google Bod Pod and find locations of testers.

Calipers are pretty good as long as the tester is experienced.

If you live near a research university, or a college that has phys ed or sports-related majors, you could probably be tested by underwater weighing. Not convenient or easy to do.

I had the calipers done at the hospital by the exercise physiologist. She has been the one that has done it all the way through this weight loss journey and did 2 while I have been in maintainence . This is what she does daily for the weight loss program so have to think she knows how to do it. She measures morbidly obese on down to maint. I was 16.5% for her,which she thought was too low . The next week I went to a fair and had it done with the obove and I was 22%. No weight change. Think I have more confidence in the calipers are at least the person who did it. I think those machine might be akin to the exercise # that the gym machines tell you you burn -not accurate


We have mobile body fat testing in my area. The truck with the tank for underwater weighing visits different health clubs from time to time. I plan to do it the next time they are nearby. You might search in your area too.

Kathy, what is the healthy range for women for body fat percentage? 16.5% doesn't sound too low to me, but I really don't know what the parameters are.


"An optimal percentage of body fat for a non-athlete is around 10-14% for men and 16-20% for women."

The reason she was a little concerned was my age. The older you are apparently the larger the # .y guess would be because you don't have as much muscle when you are my age! As old as dirt


The lowest level ("essential fat") for men is 3% and for women is 12%.

There are so many different body fat % tables it makes my head spin. Population research (e.g. with large groups) uses BMI as a proxy for body fat so we don't have as much data for body fat percentage per se. The exercise physiologists and sports dietitians do a lot more with body fat percentage testing using smaller studies.

If you are curious, here are some BF tables:

Kaiser (Prevention Program) (W=women, M=men) for adults:
Athlete: <17% W, <10% M
Lean: 17 - 22% W, 10-15% M
Normal: 22.1-25% W, 15.1-18% M
Above Avg: 25.1-29% W, 18.1-20% M
Over-fat: 29.1-35% W, 20.1-25% M
Obese: >35% W, >25% M

The Handheld BIA device had this range in its materials: Healthy range: 21-35% W, 8-24% M

Nancy Clark (Sport Nutrition Guidebook) had this table (adapted from B. Getshell):

Skinny: 14-17% W, 7-10% M
Trim: 17-20% W, 10-13% M
Average Fat ("normal"): 20-27% W, 13-17% M
Plump: 27-31% W, 17-25% M
Fat: >31% W, >25% M
