Why do I feel cold while fasting?
Quick answer
Some people feel cold while fasting because they are eating less, sitting still, or extending the fast too long.
Step by step
01 Check whether the window is too aggressive.
02 Move lightly if safe.
03 Eat enough during your eating window.
The longer answer
Feeling cold can be harmless, but if it is intense, frequent, or paired with dizziness or fatigue, treat it as a sign to adjust the plan.
Tip
Comfort matters; fasting should not feel like punishment.
Common mistake
Ignoring repeated coldness and fatigue to chase longer fasts.
