inbody

InBody Co., Ltd. is a South Korean company that designs and manufactures body composition analyzers marketed under the InBody brand. InBody devices use bioelectrical impedance analysis (BIA) across multiple frequencies to estimate body composition. Unlike single-frequency BIA, InBody instruments provide segmental analysis, delivering estimates for the arms, legs, and trunk, and presenting a range of metrics including weight, body fat mass, fat-free mass, skeletal muscle mass, percent body fat, total body water and its intracellular and extracellular components. Many models also report visceral fat level and basal metabolic rate, along with other nutrition and fitness indicators.

The devices typically employ an eight-point contact system, with sensors on the hands and feet, to perform hand-to-foot measurements. Readings are influenced by standard conditions such as hydration status, recent meals, and physical activity, so consistent measurement protocols are recommended for reliable tracking. Data is often provided in user-friendly reports that support trend monitoring over time.

InBody markets a range of professional-grade analyzers used in clinics, medical facilities, fitness centers, universities, and research settings. Notable models are designed for high-precision clinical or sports use as well as mid-range devices suitable for general fitness assessment. The apparatus is commonly used for weight management, athletic training, nutrition planning, and clinical evaluations.

Like other BIA-based methods, InBody results are estimates and subject to variability based on individual factors and measurement conditions. Users are advised to interpret data alongside other assessments and within the context of established guidelines.
