According to the CDC (2023), obesity affects 42.4%, making it one of the most common preventable causes of death. In the U.S, it is linked to approximately 111,909–365,000 deaths per year as estimated by the WHO. Obesity decreases one’s quality of life, negatively impacts mental well-being, and elevates the risks of numerous conditions such as cardiovascular disease, stroke, diabetes, some types of cancer, and obstructive sleep apnea. Excess fat can raise bad cholesterol (LDL), lower good cholesterol (HDL), and increase the risk of type 2 diabetes. This highlights the importance of monitoring body fat.

The Body Fat Calculator uses the U.S. Navy method, which estimates body fat percentage based on height, waist, neck, and hip (for females) measurement features. This method, designed to provide accurate results across a wide range of body compositions, uses these measurements in a comprehensive equation to estimate fat mass in relation to total weight. It is validated and accepted by the Department of Defense for military fitness standards.

Take a body fat measurement every 4-8 weeks to notice any meaningful change since both diet and hydration can impact changes from day to day or week to week. If checking your body fat percentage regularly, make sure to check at the same time of day each time and use the same method each time for the most reliable comparisons.
