A 12 week blueprint that combines intermittent fasting with periodized training and nutrition. You will align fasting and feeding windows to training intensity, circadian rhythms, and menstrual cycles when applicable. The plan includes lean mass macros, carb cycling by training day, intra workout fueling and electrolytes to prevent energy crashes, recovery and stress management, and practical templates for busy schedules, travel, and shift work. Weekly targets and troubleshooting playbooks make execution simple and reliable.
