First of all, fasting is a component only on our Animas Quests, and even then it is optional although strongly encouraged. If you do fast, you may experience stomach cramps, nausea, and discomfort. Some people are scarcely affected by fasting and others become weak and/or uncomfortable. While many have found fasting difficult, no one has ever become seriously ill as a result of fasting on our programs. Our protocol for initiating and breaking the fast has been developed over 20 years with the help of physicians and other healthcare professionals.
