Tanita Body Composition Scales

I'm sure these things aren't the most accurate machines around, and that there are better ways to make some of these measurements, and that some of these measurements are dubious in value at best, but I got my new $150 Tanita Ironman Body Composition Scale in the mail today.

Here's the initial readings:

weight 278, percent body fat 31.1% (goal 11-22), total body water 48.4% (normal 50-65%), muscle mass 184, basal metabolic rate 2,647 (i.e., number of cals/day to maintain wt), and metabolic age 50 (which sucks, because I'm 43).

Kinda cool to see all of the readings. I'm going to journal them for awhile to watch the trends, which is probably more important then any single reading.

One thing that jumps out at me is that the scale says that 184 lbs of me are muscle. My goal weight is 175 lbs, which would give me a BMI of under 25. This makes me wonder if this is a realistic goal?

I have an OMRON scale that is comparable to that. I'm curious to see how accurate your readings are. I don't know how tall you are but 31.1% body fat seems pretty low for your weight (unless of course you have a really muscular build).



I'm at around 27-29% body fat right now and I weigh 225. Of course I'm post-op so my body composition has shifted a lot since then but your measurements still seem off.

I love my handheld Omron (nice, b/c that way if you got big or edemaed feet you don't have to try to stand on it like a weight scale or get a skewed reading)  ..   I just wish I had bought it before my surgery, as I'm curious to know what my bodyfat % was back then (the Omron goes up to 50%!)     but hell, being a 461 lb./61 BMI bag of fluid back then, I might have even been off that scale!   

  Aimless, don't mean to be a downer, but don't forget that the body composition includes water, fat, muscle and BONE ..     Undoubtedly a lot of what appears to be muscle from your calculations is going to actually be bone (errr Boner, isn't that right?    )  I noticed the newest high-tech Weigh****chers scale takes all the above readings, plus supposedly gives you your bone density calculation as well ..  

Frank talk about the DS / "All I ever wanted to be was thin, like that Rolling Stones dude ... "

I'm fairly muscular, I think, from college football days. But I don't know how to gauge the accuracy. What I plan on doing is checking every morning, same time, and seeing how consistent it is, and watch it fall.

Don't be surprised to see big changes in your body fat % on a daily basis since hydration radically affects the results. Plus the accuracy of your scales is probably +- 5-10%.

Cool to see you monitoring your body fat though since it's really the only way to reasonably establish a "goal weight." Like you said, if your goal weigh is 175 but you have 185 pounds of muscle already, no can do unless you want to look like an Ethiopian.

Minimum body fat % for men should be around 10%, plus or minus so for a 200 pounder that means 20 pounds of fat and 180 pounds of muscle/bones/skin/water.

Cool stuff,

OK, so you guys are right, I'm disappointed to say.

I weighed again this am. 278 lbs, 38% body fat, 160lb of muscle weight.

The scale actually reads several other things as well. It gives me Bone mass. It says 9.4 lbs, which seems light to me, but is fine according to the scale literature. It also gives you a total body water reading, which was less this am then last evening, probably explaining the variation in body fat from one day to the next.

So, I'm going to use it in the am, same time every day. And watch the trends.

The weight part of it seems really consistent, fortunately.
