Health and safety
FAST/TRACK is a general wellbeing and record-keeping tool. It does not provide medical advice, diagnose conditions or determine whether fasting is appropriate for you.
Fasting may not be suitable for everyone. Seek professional medical guidance if you have a health condition, take medication, are pregnant or breastfeeding, have a history of disordered eating, are under 18, or are otherwise unsure. Stop fasting and seek appropriate help if you feel unwell.
