The body composition data type allows the user to store information on various properties of their body such as percent body fat, percent body water, muscle mass, and other properties that help describe the composition of the human body.  A user’s body composition changes as a person goes through life due to various circumstances such as diet, disease, exercise, and other lifestyle changes.  By storing this data in HealthVault, a user will be able to record their progress toward their objectives.  They can also use the tool as a preventative measure against some diseases such as heart failure, where some of the early symptoms would include sudden increase in weight and percent body water content.
