IF24 is a general wellness and timing tool, not a medical device. The metabolic phases it shows are estimated, based on typical fasting timing, and are not a measurement of your body. IF24 does not provide medical advice. Consult a qualified healthcare professional before starting any fasting practice, especially if you are pregnant, nursing, taking medication, or managing a health condition.
