Feelings over hunger may also become more tolerable over time. Studies of alternate-day fasting have shown that people rate their hunger at 8 on a scale of 1 to 10 for their first few fast days, but after two weeks, that number drops to 3. Mattson puts the window at three to four weeks, after which, he says, "you're not hungry on fasting days." (Try clean eating to shed stubborn pounds.

The Bible also gives instructions about the attitude and approach we should have in fasting. Jesus warned about hypocritical fasting, trying to show off or make others feel sorry for us.In the New Testament, Anna, the prophetess, is described as serving God day and night with fasting and prayers (Luke 2:37). We read that John the Baptist taught his disciples to fast and Jesus Christ said His disciples would fast after His death (Mark 2:18-20). Paul and Barnabas prayed and fasted when they ordained elders in the Church (Acts 14:23). And Jesus Christ fasted 40 days and nights before facing Satan in an epic battle of spiritual will (Matthew 4:2).
People can live days with no food and water, and weeks or several months consuming only water. In lab animals, when calorie intake is cut by more than 50 percent, they eventually die of complications from starvation. In the final stages of starvation, the body, depleted of glucose and fatty acids, turns to muscle protein for energy. Humans die when their body mass index (BMI) is around 12.
^ Jacobs, Henry Eyster; Haas, John Augustus William (1899). The Lutheran Cyclopedia. Scribner. p. 110. By many Lutherans Good Friday is observed as a strict fast. The lessons on Ash Wednesday emphasize the proper idea of the fast. The Sundays in Lent receive their names from the first words of their Introits in the Latin service, Invocavit, Reminiscere, Oculi, Lcetare, Judica.
In Northern Ireland in 1981, a prisoner, Bobby Sands, was part of the 1981 Irish hunger strike, protesting for better rights in prison. Sands had just been elected to the British Parliament and died after 66 days of not eating. His funeral was attended by 100,000 people and the strike ended only after nine other men died. In all, ten men survived without food for 46 to 73 days.
