Difficulty: Moderately Challenging
Step1
Decide upon the type of fast you wish to complete. The Roman Catholic church defines "fasting" as eating only one full meal per day, with no snacks allowed. Some Christians choose to fast more completely, by having only water or juice on the day of the fast.
Step2
Meditate upon the reasons for your fast. Biblical references to fasting can be found in both the Old and New Testaments. Spiritual leaders including Moses, Daniel and Jesus fasted to be nearer to God.
Step3
Consult a nutritionist or physician before beginning your fast. The best choice is a family doctor who is aware of your current state of health, your past medical issues and any chronic illnesses that might interfere with your ability to fast.
Step4
Prepare for your fast by eating small meals in the days leading up to it. Fruit, steamed vegetables, lentils and broth are all good choices.
Step5
Find recipes for liquids that are acceptable to drink during your fast. Many nutritionists and spiritual leaders recommend pure juices sweetened with honey. Broth made from celery and potatoes is also OK, as long as it doesn't contain chunks of the vegetables themselves.
Step6
Come off of your fast gently. Re-introduce foods such as fruits and steamed vegetables first. Wait a couple of days before eating anything with a significant fat or calorie content.
