How to break your fast
What you eat first matters. Here's what your body needs.
Short fast — eat normally
Start with a balanced meal. Avoid a huge carb load. Your body is ready.
First foods:
Greek yogurt, eggs, avocado, fruit
Medium fast — ease in gently
Start light. Wait 20 minutes before your main meal.
First foods:
Fresh fruit, small smoothie, or yogurt → balanced meal 20 min later
Extended fast — bone broth first
Reactivate digestion gently. Bone broth first, then wait.
First foods:
Bone broth → 30 min → small protein meal (eggs, fish, chicken)
Long fast — very gentle refeeding
Take it slow over several hours. Don't shock your system.
First foods:
Bone broth only for 1 hour → soft foods (steamed veg, soft egg) → normal meals resume next day
