During a DEXA scan for body composition analysis, low-energy X-rays pass through the body, and the amount of radiation absorbed by different tissues is measured. This allows for the differentiation between bone, lean tissue (muscle and organs), and fat mass.
DEXA scans provide accurate measurements of body fat percentage, lean mass, and bone mineral density. They are often used in research settings and by healthcare professionals to assess body composition changes over time, monitor the effectiveness of interventions such as diet and exercise, and tailor personalized health and fitness plans.
Overall, DEXA scans offer a comprehensive assessment of body composition, providing valuable insights into overall health and fitness beyond just bone density.
