Is there anything one should be cautious of before starting a Low Crap Diet?

Warning:  Be aware that embracing a low crap diet may change your life as well life on earth. A low crap diet may result in feelings of good health, happiness and self-love. A low crap diet may also affect your environment in unexpected ways, and could result in clean water, fresh air, fertile soil and fewer landfills.

Seriously though, use common sense. If you have severe food allergies, and/or you suffer from any condition that requires specialized attention to what you eat, please check with your health care provider first. Do not stop taking any medications or specially prescribed foods without proper medical supervision.
