DEXA
DEXA (also known as DXA) stands for Dual-Energy X-ray Absorptiometry. It's a widely used tool in nutrition and healthcare settings that precisely measures body composition, including bone density, muscle mass, and body fat. Think of it like a very advanced scale that can tell exactly where fat and muscle are located in the body. Nutritionists and health professionals use DEXA scans to track clients' progress, develop personalized nutrition plans, and monitor bone health. It's considered the "gold standard" for body composition testing, meaning it's more accurate than other methods like skinfold calipers or bioelectrical impedance scales.
