Pro Tips

Small moves that make the checklist easier to finish

Start with a 'gentle' fast: Don't jump straight into 18+ hour fasts. Begin with a 12-hour overnight fast, gradually extending by 30-60 minutes every few days until you comfortably reach your desired window, typically 14-16 hours.
Break your fast strategically: Your first meal (break-fast) should be easily digestible and nutrient-dense, focusing on protein and healthy fats. Avoid refined carbs or large, heavy meals immediately, which can cause digestive discomfort and blood sugar spikes.
Electrolyte balance is crucial, especially when starting: As you fast, your body flushes water and electrolytes. Consider adding a pinch of high-quality sea salt to your water or consuming electrolyte-rich, zero-calorie beverages during your fasting window to prevent headaches and fatigue.
