The effect of Ramadan fasting on fasting serum glucose in healthy adults.

Fasting during Ramadan is prescribed by the Holy Koran for every fit, adult Muslim 1. Every year during Ramadan, millions of Muslims abstain from food, drink and smoking. It should be noted that Islamic fasting is different from other experimental fasting. Muslims have two main meals during Ramadan: one after sunset and the other just before first light. Ramadan is the ninth month of the lunar calendar, and accordingly cycles through the solar year. The daily fasting period therefore varies from season to season, and between 11 and 18 hours. Several studies have elucidated the distinct effects of Ramadan fasting on human blood biochemistry. In this study, we investigate the effect of Islamic fasting on serum glucose levels in normal healthy adults.
