The Daniel Fast
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.

Advanced1 to 3 full days · water only
Water fasting is 24–72 hours of consuming only water — no food, no calories. It maximizes autophagy, ketosis, and metabolic reset, but carries real medical risks and should be approached gradually, with preparation, and ideally with professional guidance.
