Why You Should Monitor Body Water and Fat Percentage
If you're like most people, you're not drinking enough water. If you wait until you feel thirsty, your body is already suffering from the effects of mild dehydration. You continually lose water during the day through sweat, urine and breathing. The amount varies due to several reasons, including your physical activity level, illness, medications, poor nutrition, or even climatic conditions. Monitoring your body water percentage allows you to quickly compensate if your levels are low, allowing your body to function more efficiently. Having the right amount of water in your body will not only make you feel healthier, but you'll also reduce your risk of developing serious health problems in the longer term.

High body fat levels can reduce your endurance and have been linked to heart disease cancer and diabetes. Tanita's body composition analyzers monitor your body fat and body water levels with Bioelectric Impedance Analysis, or BIA, the same advanced technology used by doctors. Foot pads send a low-level electrical signal. Then BIA measures the resistance to this signal as it travels through the body.

The Tanita BF680W is calibrated for standard adults, children and athletes and stores data for 2 people, measuring body fat in increments of 0.1 percentage points. The scale's large, easy-to-read 2.25-inch, 2-line LCD shows weight and body fat simultaneously, and instantly compares these readings to healthy ranges based on the user's age and gender. Simply supply your gender, age, height and weight into the memory, step on the scale, and the monitor does the rest. The results are analyzed according to each user's information, and the result is the one of the most comprehensive at-home readings you can get at home.

Operating on four AA batteries (included), the Tanita BF680W is intended for use by persons up to 300 pounds and is backed by Tanita's three-year warranty.

Note: Pregnant women should not use this monitor, and if you have a pacemaker or other internal electronic medical device, you should not use the body fat reading feature.

5.0 out of 5 stars Precise, reliable, works well. May 6, 2007

By J. G.

Amazon Verified Purchase

I'm a personal trainer and agree that body fat can be tricky to measure. That said, this scale is very, very consistent. It will not necessarily match what you get on a dexa, etc. (my wife and I were only 0.5% from our caliper tests on athletic mode, which is pretty good since one caliper measurement to another can vary this much) so the goal is really to track your body fat and weight over time. This scale excels there. Setup a spreadsheet, measure yourself at the same time of the day, preferably right after a morning shower when your feet are moist (ladies dry your hair first), and track your progress.

Easy to setup, easy to use for two people plus random guests.

The weight is dead accurate even for doing postal packages etc.

Also, looks pretty nice.

5.0 out of 5 stars A MUST HAVE FOR ALL BODY TYPES September 29, 2005

By Ashumantha J. Thotambilu

This scale is fantastic, the measurements and accuracy of this scale are top notch. Moreover, having the body water percentage feature allows you to really monitor the amount of body fat on you. For example, to reduce your PERCENT body fat, just drink more water and it will go lower, but if you subtract the water percent from your actual weight and body fat, u can really monitor the number of pounds of fat you have on your body.

It's very durableand all my friends who workout alot use it and are extremely satisfied. The athletic mode is very useful too because it allows for greater accuracy

5.0 out of 5 stars A good tool for tracking bodyfat changes August 4, 2006

By D. Thomas

The scale won't be as accurate as DEXA or underwater weighing, but it is sufficient to track changes in bodyfat. That is all I need to know, if my bodyfat is increasing or decreasing.

I recommend checking your bodyfat every day at the same time under the same conditions and using your weekly average to track your bodyfat.

5.0 out of 5 stars A consistent scale March 19, 2007

By Matthew W. Gant

i'm absolutely obsessed with weighing myself constantly to see how running a mile or drinking a glass of water effects my weight. i was looking for a consistent scale and i finally found one. Although I believe it consistently weighs me 1 lb less than I really am, I am happy to get a consistent weigh within 0.2 lb accuracy. For example, I can stand on the scale 10 times in a row and i'll get the same weight every time within .2 pounds. The body fat and body water I don't trust to be accurage, but they are very consistent (+-.75%) which is most important to me. Overall, this scale has surpassed my expectations with it's consistent results.

3.0 out of 5 stars Save your money if buying this scale for body fat percent. July 9, 2007

By Yannick Salgleda

I bought this scale because I was looking for a digital scale and also wanted to see if my body fat measurements that I have been taking with the Accu-Measure Body Fat Caliper was accurate. As a weight scale, the Tanita is excellent (and the reason I gave it as many as 3 stars) and I decided to keep it despite the body fat being off. I exercise regularly and I never get a reading below 18% bodyfat and varies between 18% and 20% - even in athletic mode. With my $7 calipers it tells me I am about 14.8% body fat. I was recently tested in a gym and I was at around 13-14% so the cheap plastic gadget did much better. So save your money - buy a plain old digital scale and the Accu-Measure Body Fat Caliper here at Amazon and with the savings go have a nice healthy dinner!

5.0 out of 5 stars Accurate, a must-own if you're trying to lose fat June 20, 2008

By Charles Dickens

I use the caliper method along with this, and the results are always approximately equal. This scale won't give you your exact bodyfat, but the number it gives you is pretty accurate, which you can tell just based on looking in the mirror and going on the net and looking at what different bodyfat percentages look like, and more importantly it will tell you if your bodyfat percentage is going up or down. When I'm dieting and exercising properly, the number goes down by small increments each time. When I'm stuffing myself and not going to the gym enough, the number goes up. The negative reviews are from people who probably didn't follow the procedure correctly.

The weighing scale is extremely accurate, and you should take that measurement in the morning after you've used the bathroom and before you have eaten. The body fat measurement should be taken later in the day, and you shouldn't be full or food or water.

One tip: don't use the athlete setting unless you are an actual athlete, because it'll give you far too flattering a reading. If you are an active person who goes to the gym three times a week and does weight training and cardio, that does not make you an athlete. If you play sports for a few hours five times a week, then you can probably use the athlete setting.

5.0 out of 5 stars at last, accuracy February 10, 2007

By mjd

Bought this scale after reading the reviews. Am very happy with it. It is the first scale I have ever had (including several high priced digitals) that actually gave accurate and consistent readings. If I step on it three times in a row, it gives the same reading, most do not. And it even does tenths. I love it. I was shocked, tho, one day when it said I had lost half my weight. I then realized that my cleaning folks had inadvertently changed it from lbs to kgs. I had a good laugh!
