Hour Zero is a general-wellness tool, not medical advice, and does not diagnose, treat, or prevent any condition. Talk to your doctor before fasting — especially if you are pregnant or nursing, have diabetes or low blood pressure, take medication, or have a history of disordered eating. Made by JAK Apps.
