This review covers experimental methods to determine human body composition, including fat, water, and protein. Advanced techniques and simple measurements now allow detailed quantification of body components in health and disease.

Area of Science:

  • Human physiology and experimental methods.

Background:

  • Accurate determination of human body composition is crucial for understanding health and disease states.
  • Numerous experimental methods have been developed over time to assess body composition at various levels.

Purpose of the Study:

  • To review the development and current status of experimental methods for determining human body composition.
  • To highlight the utility of these methods in quantifying body components and tracking changes.

Main Methods:

  • Body density, dilution techniques for total body water, potassium measurements for body cell mass.
  • In vivo neutron activation analysis for protein, dual-energy absorptiometry (DEXA), CT, MRI, fMRI, MRS for tissue/organ analysis.
  • Bioimpedance analysis (BIA) and anthropometry for accessible measurements; in vivo trace element analysis.
