How to Fast Safely

Dr. Bill Bright

As you begin your fast, you may hear from concerned loved ones and friends who urge you to protect your health. And they are right — you should protect your health. But I assure you, if done properly, fasting will prove to be not only a spiritual blessing but a physical blessing as well.

By all means, consult your doctor before you begin your fast. But be aware that many doctors have not been trained in this area, so their understanding may be limited. Even so, it would be wise to ask your doctor for a physical exam to make sure you are in good health. You may have a physical problem that would make fasting unwise or dangerous. Also, if you are taking any type of medication, make sure to talk to your doctor before changing your regimen. Prudence and caution are in order.

When you are assured that you are in good health, you are ready to begin your fast. Follow the guidelines in the pages on physical preparations and maintaining nutritional balance and health.

In spite of the safety and benefits of fasting, there are certain people who should never fast without professional supervision. For example:

  • People who are physically underweight.
  • People who are prone to anorexia, bulimia or other behavioral disorders.
  • People who suffer from weakness or anemia.
  • People who have tumors, bleeding ulcers, cancer, blood diseases or heart disease.
  • People who suffer from chronic problems with the kidneys, liver, lungs, heart or other vital organs.
  • People who take insulin for diabetes or suffer any other blood sugar problem, such as hyperglycemia.
  • Women who are pregnant or nursing.
