Fasting has been common throughout history . It is the act of willingly abstaining from some or all food, drink, or both, for a period of time. It is often used as a method of non-violent resistance to effect political change. Famous fasts include the forty hour fast by World Vision to bring awareness to poverty and hunger around the world. Mohandas K. Gandhi conducted several prolonged fasts as effective political and social protests.
The London 2012 Olympic Games, which run from 27th July to 12th August, coincide with the Muslim month of Ramadan in the Islamic calendar. One of the five pillars of Islam is to fast during this holy month. All able-bodied Muslims are expected to fast, unless they have a valid reason not to, for example those that are travelling, sick or facing heath risks.
