What you'll learn

Key ideas in Intermittent Fasting Mastery

  • Insulin sensitivity is naturally highest in the morning and early afternoon
  • High-intensity training requires nutrient availability for muscle repair
  • Aligning feeding windows with peak insulin sensitivity
  • Late-night eating coincides with melatonin rise, which impairs insulin response
  • Low-intensity activity can be fueled by stored body fat during an extended fast
  • Adjusting windows based on training intensity
  • Hormonal down-regulation from over-fasting
  • Cortisol and sleep disruption
  • Biofeedback as a metabolic indicator
  • Shortening the fast to fix plateaus
  • Late-night feeding disrupts the circadian clock and metabolic repair
  • Identifying signs of hormonal compromise from over-fasting
  • Early time-restricted feeding (eTRF) typically shows superior insulin outcomes
  • Prioritizing window adjustments when goals are no longer being met
  • Protein and fats consumed first blunt the insulin response of later carbs
  • Chronic low-calorie fasting can signal the thyroid to slow down metabolism
