Many websites do sell body fat scales to purchase for home use. You can go to Walmart.com, Amazon.com, Target.com or sears.com and compare their body fat scales to see which one you like best.
A body fat scale, also known as a BMI (Body Mass Index), measures the amount of fat in a person's body. http://en.wikipedia.org/wiki/Body_fat_percentage#From_BMI
You can buy special scales, that can tell you the percentage of body fat and muscle.
Scale can measure body fat accurately by using bioelectrical impedance analysis, which sends a low-level electrical current through the body to measure the resistance of body tissues. This information is then used to calculate body fat percentage.
As a female, your percentage of body fat should be about 15 to 20% for good health. (For males the percentage of body fat should be about 10 to 15% for good health.) To determine your percentage of body fat at home, obtain some plastic body fat calipers and do a simple skin-fold test. Body fat calipers are not expensive, are readily available to buy, and can replace a scale or balance.
The best device to measure body fat is an expensive tool that trainers and fitness / nutrition professionals use to assess their clients. Many scales, such as the Weight Watchers Scale, can measure body fat. This scale is available from big-box retailers like Target.
Tanita does indeed sell body fat scales. They sell many different types of scales as well. I am including a link to a body fat scale sold on the Tanita website, http://www.tanita.com/en/bf683w-scale/
There are several places where you can buy a body fat analyzer. Wal-Mart and Amazon both carry this product.
Your scale measures body fat accurately by using a method called bioelectrical impedance analysis (BIA). BIA sends a small electrical current through your body to measure the resistance of different tissues, such as fat and muscle. Based on this resistance, the scale can estimate your body fat percentage. It is important to note that while BIA can provide a general idea of body fat percentage, it may not be as precise as other methods like DEXA scans.
You can find information about a body fat scale by typing in the key words in google. Google will give you different links to different sites where you can find out more information.
The best way to analyze your body fat when you are at home, is either weigh yourself with a scale or calculate your BMI. A bmi is a height/weight that calculates your body mass index. Which is your fat.
For a scale that also calculates body mass index, try the Biggest Loser 5568 Body Fat-Body Water Scale. This product is being sold at Walmart.
A body fat meter provides more detailed information about body composition compared to a scale that only measures weight. However, body fat meters can sometimes be less accurate than more sophisticated methods like DEXA scans. It's important to use such tools as part of a comprehensive approach to health and fitness.
