There are four basic techniques to calculate body fat. These are Home Body Fat Scale, Navy Method, Hydrostatic Weighing and Skinfold Caliper but we will focus on top three, most commonly used.
Home Body Fat Scales technique evaluates the amount of body fat by method of Biometrical Impedance. By this method an enormously low voltage current is passed through our body and the opposing current is measured. Upon coming to the result and comparing it with the actual body weight, the exact percentage of body fat is determined.
This method of how to calculate body fat can render some errors, because the resistance of our body is affected by a variety of factors that produce some current along with body fat, such as the body water, electrical waves of heart, skin temperature, skeletal muscles, and physical work out. In order to overcome this obstruction an individual has to rest for 4-5 hours and avoiding any physical exercise 12 hours prior to the method applied.
Skinfold Caliper is another useful technique to calculate body fat conducted with the usage of calipers. This is the cheapest technique for measuring body fat. However, in order to achieve the best results, the procedure should be done correctly by an expert.
Hydrostatic Weighing, previously known as under water weighing, is the most precise technique to calculate body fat, on condition you provide a hydrostatic weighing tank. It is necessary to know Archimedes Principle in order to understand this technique. It would be even better if you knew some physics too. The mass of your body is calculated by measuring the amount of water that you relocate while you are in the water. It happens because the amount of water relocated when the body totally or partially gets into the water is equivalent or proportional to the weight of that body. Depending on the body density, the method calculates body fat. The only problem that might crop up is how to find a hydrostatic weighing tank.
But above all, the main question is why bother calculating body fat?
An important constituent of a successful weight loss diet plan is body fat. Before you decide to go on a diet it is necessary to understand scientific aspects of your weight loss program. That means you should know the inventory of your body fat and the time it needs to lose some portion. Besides this, you should get information about the amount of calories you need to reduce for achieving the goal. How to calculate body fat correctly is the first and foremost step in your pursue of weight loss goals.
