Fasting Arc
The predictable progression of physical and mental states during a fast.
A fast usually follows a pattern where hunger rises, settles, and then becomes more stable. Early hours can feel easy, followed by a more difficult phase where cravings increase. After that, many people notice clearer focus and reduced hunger. Knowing this pattern helps you stay calm when discomfort appears and understand that it will pass.
