Why do I feel lightheaded when fasting?
Quick answer
Lightheadedness is a safety signal; shorten or stop the fast and consider medical advice if it repeats.
Step by step
01 Check the symptom or risk before thinking about streaks.
02 Shorten, pause, or stop the fast when the body gives warning signs.
03 Ask a qualified professional when symptoms repeat or medical conditions are involved.
The longer answer
Lightheadedness is a safety signal; shorten or stop the fast and consider medical advice if it repeats. The page should help the user decide what to track and when to stop. It should not push fasting harder when the user is describing symptoms or risk.
Tip
Safety pages can still convert by building trust.
Common mistake
Framing discomfort as proof the fast is working.
Track in the app
Track symptom timing, fasting duration, caffeine, hydration, sleep, and first meal.
