Type of body fat measured (e.g., subcutaneous, visceral)
Body fat calculators based on height and weight typically estimate subcutaneous body fat, which is the fat that lies just beneath the skin. However, some calculators may also estimate visceral body fat, which is the fat that surrounds the organs in the abdominal cavity. Visceral body fat is more dangerous than subcutaneous body fat, as it is associated with an increased risk of heart disease, stroke, and type 2 diabetes.
- Subcutaneous Body Fat
Subcutaneous body fat, also known as “superficial fat” or “belly fat,” is the type of fat that is found just beneath the skin. It is the most common type of body fat and is typically what people are referring to when they talk about “losing weight.” Subcutaneous body fat is generally considered to be less harmful than visceral body fat, as it does not pose the same health risks.
- Visceral Body Fat
Visceral body fat, also known as “deep fat” or “organ fat,” is the type of fat that surrounds the organs in the abdominal cavity, including the liver, pancreas, and intestines. Visceral body fat is more dangerous than subcutaneous body fat, as it is associated with an increased risk of heart disease, stroke, and type 2 diabetes.
- Ectopic Body Fat
Ectopic body fat refers to fat that is stored in places other than the subcutaneous tissue and the abdominal cavity, such as the liver, heart, and muscles. Ectopic body fat is associated with an increased risk of insulin resistance, type 2 diabetes, and cardiovascular disease.
- Brown Adipose Tissue
Brown adipose tissue (BAT) is a type of fat that is found in small amounts in humans and other mammals. BAT is different from white adipose tissue (WAT), which is the type of fat that is stored in the subcutaneous tissue and the abdominal cavity. BAT is more metabolically active than WAT and can help to burn calories and generate heat.
The distribution of body fat can vary from person to person. Some people have more subcutaneous body fat, while others have more visceral body fat. This distribution can be influenced by factors such as genetics, age, sex, and lifestyle. Body fat calculators that measure visceral body fat can be useful for identifying individuals who are at an increased risk of developing obesity-related health problems.
