Abstract
Bioimpedance analysis is widely used in scientific and clinical practice to assess component body composition. However, it is known that the results of bioimpedance analysis can be influenced by various external factors, including food intake. The purpose of this study was to investigate the nature and extent of changes in bioimpedance parameters after a single meal and to identify possible correlations of these changes with the amount of food and liquid consumed. Male students participated in the study, bioimpedance analysis was performed on the InBody 770 device twice – before and 10 minutes after a meal. The data obtained showed a statistically significant increase in most body composition parameters, especially water volume, protein, muscle and fat-free mass, and mineral content. At the same time, the fat content remained unchanged. Correlation analysis revealed inverse relationships between the volume of food ingested and a number of parameters, including lower limb phase angle. The obtained results emphasize the need for strict standardization of bioimpedance analysis conditions, in particular, taking into account the time and volume of the last meal to ensure correct interpretation of the data.

Keywords: bioelectrical impedance analysis, food intake, body composition, phase angle, intracellular water, measurement standardization
