Prophet Mohammed is reported to have said that one’s worst weakness is one’s belly. If you must eat make sure you fill one third of your stomach with food, one third with water and leave one third for air i.e. leave it empty. “The stomach is the tank of the body and the veins go down to it. When the stomach is healthy the veins come back in a healthy condition, but when it is in a bad condition, they return diseased.”

The Prophet  asked the companions to wash their hands before and after, to start eating with the praise of Allah, to eat using the right hand, not to eat until they really felt hungry, not to eat and drink excessively.
