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
