20:4 Warrior Fasting
Advanced20 hours fasting · 4 hour eating window
20:4 fasting — also called the Warrior Diet — is a 20-hour daily fast with a 4-hour eating window, typically one main meal in the evening. It deepens autophagy, ketosis, and fat oxidation significantly, but demands careful meal construction and is best for experienced fasters.

Moderate21-day partial fast · plant-based whole foods only
The Daniel Fast is a 21-day partial fast of plant-based, whole foods — no meat, dairy, sweeteners, or processed foods — modeled on Daniel 10:3 (ESV). It is a seasonal spiritual discipline, not a daily eating window, and is one of the most practiced Christian fasts today.
