A bathroom scale today is much more than what it used to be. In the past you used your bathroom scale to calculate your body weight and nothing more. Today, bath scales have evolved into something much more sophisticated and feature rich. Although body weight is important in your overall health vitals, there are other metrics that contribute to your well-being.
The definition of body fat is simple. Body fat percentage, or BMI, is the weight of a person's fat divided by that person's overall weight. A body fat reading of 30%+ is considered obese.
When looking for a digital bathroom scale you should consider purchasing a model that not only determines weight, but also body fat. This scales are also called bmi scales. Other nice features include memory for saving past measurements and multiple person use. This will allow more than one person in the household to save their readings to a customized profile just for them.
