Whats the real deal with carb-loading for climbing? Is it just a myth perpetuated by the cycling industry to sell more energy gels and bars? Ive seen plenty of experts claim that consuming complex carbs 2-3 hours before a climb will provide a boost of energy, but whats the actual science behind it? And what about the role of protein and healthy fats in sustaining energy levels? Are we just ignoring the importance of a balanced diet in favor of quick fixes and magic bullets? And what about the added challenge of carrying extra weight - does the traditional carb-loading approach even apply in those cases? Can someone provide some real evidence and insight, or are we just peddling the same old myths and misconceptions?
