When fasting, Muslims are required to abstain from food, beverages (including water), and sexual intercourse during daylight hours (from dawn to sunset).
This sort of fasting, however, is actually a series of feasts. Most Muslims celebrating Ramadan eat a tremendous amount of food before sunrise and again after sunset. Numerous reports have shown that Muslims consume far more food during Ramadan than during other months. The results are obesity, diabetes, and other health problems.
This tendency to feast and call it "fasting" draws attention to a deeper problem in Islam.
