True or False: Bioelectrical impedance analysis (BIA) is a method to determine body composition.

Bioelectrical impedance analysis (BIA) is indeed a method used to determine body composition. This technique works by sending a low-level electrical current through the body, which measures the resistance (impedance) encountered. Different body tissues, such as fat, muscle, and water, have different levels of conductivity, allowing the analysis to estimate body fat percentage, lean body mass, and total body water.

As a non-invasive and relatively simple method, BIA has become popular in both clinical settings and fitness assessments to provide insights into an individual's body composition. The accuracy of BIA can vary based on hydration levels, the specific device used, and individual characteristics, but it remains a widely accepted and convenient technique for assessing body composition.
