Sunfold tracks when you eat. It cannot know anything about your health, and it does not diagnose, treat or advise.
Everything in Sunfold, including the metabolic phases, is general educational information. It is not a diagnosis, a treatment plan, or a recommendation for you personally.
Please speak to a healthcare professional before fasting if you are pregnant or breastfeeding, under 18, living with diabetes or taking medication that affects blood sugar, taking any medicine that must be taken with food, underweight, or living with a chronic condition.
Dizziness, faintness, confusion, a racing heart or unusual weakness are reasons to eat and to seek medical help. No streak is worth it.
If you have or have had an eating disorder, or if tracking meals makes you anxious, a fasting app can make things worse. Please talk to a doctor or a support service where you live before using Sunfold.
The hours shown for each metabolic phase are approximations from general research. What actually happens depends on your last meal, your activity, your sleep and your body. Treat them as a rough map, not a measurement.
