A body fat calculator is a tool that estimates the percentage of fat in a person’s body. It typically uses measurements such as height, weight, age, and gender to determine the body fat percentage. For example, a person who inputs their height, weight, age, and gender into a body fat calculator may receive a result that states they are obese.
Body fat calculators are relevant because they can help people to track their progress towards weight loss or fitness goals. They can also be used to screen for obesity and other health risks. One of the key historical developments in the field of body fat measurement was the development of the bioelectrical impedance analysis (BIA) method in the 1960s.
