The worst smelling stools belong to meat eaters, consumers of grease and fats and highly refined foods and sugars. These foods tend to stay longer, and sometimes permanently in the intestinal track where they decay, putrefy and poison the body. It isn't necessary. If you've never fasted before, do a colon cleanse first and learn more about your body's needs before going into a fast. The key is to educate yourself in order to take responsibility for your health.
Some people believe that colon cleansing is only beneficial when accompanied by fasting.
This is simply not true. In fact, if you're new to detoxification efforts and not sure what you're doing, it is a speedy way to undermine and devitalize the body. It's important to weigh the benefits based on your individual situation. For instance, if you suffer from hypoglycemia, fasting along with colon cleansing is not advised. Colon cleansing or bowel irrigation should not be confused with a typical enema.
