Body Fat Index

Body Fat Index

High body fat can increase the risk of conditions such as diabetes and cardiovascular disease. Having too little body fat can also be harmful, potentially affecting fertility, immunity, and heart health.

Body mass index (BMI) is a rough estimate of body fat percentage. It is useful as a rough guide, but it has limitations. For example, people with high muscle mass may have a high BMI without high body fat.

Accurately measuring body fat is essential for assessing health risks.

Determine Your Body Fat Percentage

Use a tape measure to determine your waist, hip and neck circumference. Then input your gender and measurements below to receive a body fat index based on average values. The body fat index is not an indicator of fitness level since the calculation is made with no regard to height or weight.
