This is an advanced practical course designed to empower the trainee to design and manage their own nutrition and training program for fat loss, based on clear scientific principles and precise calculations. The course serves as a culmination of previous preparatory courses, transitioning the trainee from theoretical understanding to independent practical application. It focuses on teaching how to assess body status, calculate caloric and nutritional needs, organize and manage calories, and design a training program aligned with fat loss while preserving muscle mass and managing fatigue. The primary goal is to build the ability for self-planning and making correct decisions without constant reliance on a coach, while providing general supervision and feedback to ensure correct application.
