A very interesting article - but remember 'correlation does not equal causation'! Personally I love coffee, but there is a high level of acrylamide in instant coffee so I limit instant coffee to one a day. Ground coffee is enjoyable but can disrupt my sleep, so again I limit it to one a day.

IIRC, coffee increases cortisol, so if you are fasting, coffee can help you get through the hunger. Whether you want to repeatedly stimulate your cortisol receptors chronically and regularly is another matter. It may be best to skip coffee every other day, or at least vary your intake.
