  Planck Fasting is a tracking tool, not a medical device. Talk to a qualified clinician
   before starting any fasting protocol, especially if you are pregnant, breastfeeding, 
  taking medication, or have a history of disordered eating.

  aesthetic, same hbar mark, same idea: do one thing, do it well, then get out of the   
  way.
