The purpose of this case study was to implement an evidence-based dietary approach to peaking for a bodybuilding competition and monitor its impact on body composition, muscle thickness (MT), intra- to extracellular fluid shifts, subcutaneous thickness (ST), and hydration status. Secondarily, it aimed to document any adverse events of this peak week approach in a small, controlled setting. Methods: Dietary practices were recorded, and laboratory testing was conducted throughout the peak week, including competition morning. The data suggest that the prototypical goals of bodybuilders’ peak week (i.e., increasing muscle fullness, decreasing subcutaneous thickness) to enhance their aesthetics/muscularity presented can be achieved with a drug-free protocol involving dietary manipulations.
