Best body composition scale?

Which body composition scale is best for measuring body fat and muscle percentages? The one I'm currently using isn't accurate at all.


The Best Answer

I currently use a pretty gadgety scale. I picked up the Withings scale last year. In the last few days, I've found that it takes stepping on the scale a couple times to get the most consistent day-to-day results. Another benefit of this scale is that it automatically uploads your data to a website. For example, here's my data:

I may be in the minority here but I believe that it really doesn't matter what you use, as long as you use said tool(s) under the same conditions (your control) for each measurement. Case in point, I bought a Homedics scale that supposedly measures BF%, muscle mass %, water weight % and bone % along with the obvious total lbs. Whether or not it's the most accurate I don't care as I take the measurement at the same time every time and under the same conditions i.e. right after waking up but after using the bathroom.

I may not have insanely accurate numbers but by using the same tool under the same conditions each time, I can chart my progress.

All body composition scales are notorious for inaccurately accounting for water weight. The recommended way to get an accurate reading on the body composition scale is by drinking a bunch of water in the morning, and then weighing yourself right after 'using the restroom'. See if that helps.

I'm using the Omron Full Body Sensor Body Fat and Body Composition Monitor and it's not very precise at measuring body fat from day to day, but it does a decent job of estimating body fat changes over longer periods of time. For example, last August it said I was 18% body fat, and now I'm 25%, even though I didn't lose any weight, I wasn't exercising at all so my muscle just turned into fat. However, if I weigh myself in the morning and in the evening, there might be a 2% difference depending on how much water I drank. So you need to take it with a grain of salt. If you use it in conjunction with a caliper, you might have better results!

If you can't end up finding a reliable scale, you can always go the old fashioned analog method using a measuring tape and doing the whole 'total inches' approach. I think a bunch of people here are doing that instead of the scale.

I was tired of relying on inaccurate electric scales, so I got a highly rated $5 caliper from Amazon.com (I posted a question with links to the product). This seems to be the most effective method, for those willing to spend a few minutes with it.

Of course, they are only useful to a certain point-- they aren't accurate at all for obese people, in which case an electric scale is best. However, if you are already mostly lean and want to find out if you are at 12% or 9%, this is the way to go.

I wouldent waste my money on any of those scales!

I already have a scale from a couple years ago which does BFC and it doesnt work.

I cant use callipers because i'm too overweight (210lbs). I record my weight and inches with a tape measure. And is long as you're seeing the numbers reducing thats good right?

I think you can safely assume that if you're weight is reducing and you're losing inches, you are losing body fat and you are getting closer to your goal.

I am using a high tec scale in Boots (pharmacuitical & beauty store) once a week to see if it actually corresponds to my scale at home. It measures hight, weight BMI and body fat. I'm not taking the measurments partculary seriously but it's interesting to see what they will say!

We like the Tanita scale - Tanita BC-551 InnerScan Body Composition Monitor - http://www.tanita.com/en/bs551/

It tells you not only weight and body mass, but also hydration, muscle mass, bone density, etc. Some trusted personal trainers highly recommend the Tanita brand for accuracy.

Of course, I doubt any home scale is 100% precise, but it's good to have some guidelines as you travel on your Slow Carb journey ;-)
