An analysis of your body composition can provide valuable information about your health. Various methods of body composition analysis (BCA) assess the content of fat, muscle, and bone in a person’s body. Many modern scales and even wearable devices provide body composition data, including estimates of the amounts of fat, muscle, bone, and water present.


Often, the goal of BCA is to determine whether a person has too much or too little fat in the body, putting them at risk for various conditions like cardiovascular issues, type 2 diabetes, bone loss, and heightened susceptibility to infection. BCA is also used to track the effects of weight loss and athletic training programs. In this article, we’ll examine various methods of BCA, their accuracy, and how they can support various health goals.
