Fasting Is Not for Everyone
Some of us are not meant to fast at certain times, or ever. For Muslims, if a person is ill, he or she does not have to fast but must make up the day later. There are other times a Muslim should not fast (traveling, pregnancy, nursing, etc.). And you shouldn't fast if it comes to the point where it will harm your health. Sure, fasting is a wonderful way of inner spiritual cleansing. But there are other things we can do if we can't fast, such as feed the poor. Meditation, reading scripture, reciting prayers, doing acts of charity--all these acts help turn up our spiritual dial.
