Ramadan runs from 22 August in accordance with the Islamic calendar and participating Muslims are expected to fast froom food, drink and other vices between the hours of dawn and sunset.
Club doctors have designed a special program to keep the players hydrated as training in the intense Spanish summer heat without being able to take on fluids can lead weakness and possiby to serious injury, while some level of weight loss is a normal feature of the fasting process.
Fortunately for Los Merengues, Ramadan will not impact heavily on the playing schedule with only three games affected, La Liga fixtures against Deportivo, Espanyol and Xerez.
France internationals Lassana Diarra and Karim Benzema will also have to factor in two France games against Romania and Serbia in the month ahead.
Sport reports that Barcelona trio Erical Abidal, Keita and Yaya Toure, all Muslims, will delay their Ramadan fasting to honour their professional commitments with the club.
