What is the Bioelectrical Impedance Method?
Bioelectrical Impedance (BI) is considered one of the most accurate and accessible methods of screening body fat. Muscles, blood vessels and bones are body tissues having a high water content that conduct electricity easily. Body fat is tissue that has little electric conductivity. The monitor sends an extremely weak electrical current through your body to determine the amount of fat tissue. The weak electrical current is not felt while operating the Body Fat Analyzer. The monitor is calculated by a formula that includes five factors; electric resistance, height, weight, age and gender.
What is visceral fat?
Visceral fat is located around the organs. Too much visceral fat is thought to be closely linked to increased level of fat in the bloodstream, which can lead to common conditions such as high cholesterol, cardiovascular disease and diabetes. Sedentary life style causes excess visceral fat, and exercise can reduce it quicker than subcutaneous fat (fat located under skin).
What is resting metabolism?
Resting metabolism is the energy to maintain vital functions and it counts 60 to 70% of total energy consumption. Knowing your resting metabolism can help your dietplan. If you can increase daily activity while keeping food intake at resting metabolism level, you can lose weight.
What is skeletal muscle?
Skeletal muscle is muscle attached to the bones that is used to move the body. If you do weight loss without exercise, you may lose skeletal muscle. Skeletal muscle is important to maintain your resting metabolism as well as your functionality. Monitoring skeletal muscle during weight loss is key to avoid weight rebound in the future.
