Product Description

The Tanita BF-679W Multi-Frequency Body Fat / Body Water Monitor calculates body fat and body water levels using Bioelectric Impedance Analysis (BIA) technology. By sending a safe, low-level electrical signal through the body, Tanita’s exclusive FDA cleared BIA technology, measures weight, body fat, and body water %. BIA is quick and non-invasive, and is one of the most thorough and reliable ways to measure body composition, clinically comparable to DXA (dual-energy x-ray absorptiometry) and hydrostatic (underwater) weighing.

The BF-679W features a weight capacity of 300 pounds, it operates for greater than 2 years on four AA batteries (included).

Tanita's Body Water Range Chart

Total Body Water % Measurement

Total Body Water % is the total amount of fluid in the body expressed as a % of total body weight (applicable for ages 18-99). Body water levels naturally fluctuate through out the day. Bodies tend to be dehydrated after a long night sleep and there are difference in fluid distribution between parts of the day. Body water % should act as a guide and should not be used as an absolute. It is meant to be used to track long-term changes in the total body water % and maintain a consistent, healthy body water %.

The average TBW% ranges for a healthy person are: 45 to 60% for females and 50 to 65% for males

Note: Total body water % will tend to decrease as the percentage of body fat increases. A person with a high % of body fat may fall below the average body water %. As you lose body fat, the total body water % should gradually move toward the average range.

Tanita Body Fat Health Range Indicator

Body Fat % Measurement

Body Fat Percentage is the proportion of fat to the total body weight (applicable for ages 7-99). Following body fat % measurement, a black bar will flash along the bottom of the display, identifying where the measurement falls within the Healthy Range Indicator.

50 customers mention32 positive18 negative

Customers are mixed about the body fat. Some mention that it measures body water and fat, and is a great way to measure your body fat and monitor it over time. However, others say that the variability of the bodyfat percentage (within 5% points) seems to be an issue, and there seems to been some bias in the fat percentages given based on sex. The electrode sensors only measure body fat from your lower body.

"...The fact that it tracks body fat and water is also a plus since it seems like the only scales that do that are "smart scales" made of glass...." Read more

"There seems to be some bias in the fat percentages given based on sex...." Read more

"...As for reading the display, numeric characters display well, but the BMI indicator (-, 0, +) is sometimes hard to see clearly for older eyes...." Read more

"...As for it's accurate determination of "body fat" and "water", I can't say, but feel these are a bit gimicry anyway...." Read more

34 customers mention13 positive21 negative

Customers are mixed about the readability of the scale. Some mention it's easy to set up and use, with clear readings, while others say that it'll give you a different reading every time.

"...It just goes to multiple zeros and refuses to shut off...." Read more

"...I think it’s easy to read. Once you set up your personal settings you tap the one button and it will show you your previous values...." Read more

"...than I got 5 years ago in Japan, the quality may be so so and not very countable - But I was wrong. It's still good quality...." Read more

"...The body fat and water is WAY off. The numbers don't add up at all...." Read more

Works on carpet, woohoo!  But with a (big) catch.

Works on carpet, woohoo! But with a (big) catch.
I loved my old Tanita body fat scale (TBF-621), but it finally gave up the ghost after 15+ years. I need to use it on carpet since my bathroom is too cramped for a scale. There are carpet feet on the old Tanita which elevate it enough to work great on low-pile carpet. I called Customer Support and was informed there are no carpet feet available for the new models, and moreover, the ones from my old scale (which are removable) won't fit. Based on this, I instead bought the EatSmart scale, since one article said it worked on carpet. Wrong. It wouldn't even turn on when stepped on -- it just sank into the carpet. I then bought a British scale (Salter) from amazon.co.uk which was advertised as having carpet feet. But it under-reported my weight by 40 lbs. Finally, after comparing the underside of my old model to pictures on Ebay of the BF-679w, I decided to take a chance on it. Sure enough -- despite Customer Support's claims -- the old carpet feet fit the new model perfectly. See attached images of the old scale (top and bottom), carpet foot, new scale (top and bottom), and the new scale with the carpet feet swapped in. As with the old Tanita scale, the measurements on carpet are just as accurate as on a hard surface. So happy to again have a working body-fat scale!The issue, of course, is that if you don't happen to have carpet feet from an old Tanita scale, I'm not sure how to get them for the new one. Perhaps a different Customer Service representative can be more helpful? Very annoying that Tanita will not provide them, given that they used to. Maybe they will reconsider if enough customers ask for them?
