## 6 Limitations  
This paper has several limitations that must be recognized in order to properly evaluate the conclusions and their applicability. Without a control or comparison group, it is difficult to directly link the observed changes to nutritional intervention or to exclude the influence of other factors (training, stress, and natural variations).  
Also, observed changes in the resting metabolic rate (RMR) and body composition (BMI) may be significantly influenced by the volume and intensity of training, not only by the nutritional intervention. Competition or other external events may affect metabolism and food intake, but these are not detailed or quantified in this study.  
This paper provides valuable insights into the relationship between nutrition, RMR, and body composition in a high-performance context, but its limitations emphasize the need for future larger and better controlled research. These could include larger longitudinal group studies, experimental designs with control groups, and the integration of additional variables to support the validity and applicability of the findings.
