Around 60 of those days Copts live on a vegan diet, and for the rest they may eat fish but refrain from other meat or animal products and similar to Muslims also refrain from eating food from sunrise to sunset (see Marie Henein's great article for some excellent recipes and info on veganism in the Coptic Church). The Coptic Church sees fasting and asceticism in a positive spiritual light, as an emulation of the life of Jesus (Matt. 4:2), and also of Moses and Elijah (Exod. 40:28; 1 Kings 19:8), and a sublimation to the glory of God and an expression of love.
As with the Coptic Christians, Muslims in Egypt view fasting in a highly positive sense. Fasting during Ramadan is one of the five pillars of Islam. The time of fasting is not just about abstaining, but also about doing good deeds, increasing compassion and mercy for the suffering of others, developing self-control, and love of others and of God. "O you who believe! Fasting is prescribed for you as it was prescribed for those before you, that you may become Al-Muttaqun (the pious)." [Soorah al-Baqarah (2):183] Muslims also fast outside of Ramadan as well, though it is not required of them unless they are making up for days lost during Ramadan (as in the case of travel for example, wherein they are exempt).
