The practice of fasting is so clearly associated with Lent that common usage now associates it with voluntary forbearance of just about anything, especially over periods of a day or more and especially in conjunction with religious practices. For this post, however, fasting will refer to voluntarily not eating food (or certain foods), specifically during, or on certain days during, Lent. Even with this narrower definition, it is not possible to cover the range of practices in common use.
Some practices, however, are so common as to be unavoidable. Perhaps the all-time, most popular Lenten discipline is the partial fast, giving up a particular food or type of food during Lent. Examples include chocolate, desserts, candy, sweets, snacks, coffee, alcohol, fast food, or meat. Often, this discipline is kept unbroken, even on Sundays, though Sundays are technically counted as feast days, even during Lent. While giving up any habitual food is difficult, selecting one particular food or group of foods can remove or soften some temptations to break the fast, since refusing a single dish on temporary religious grounds is generally socially acceptable.
A more difficult fasting discipline is the single day per week complete fast, traditionally Friday, in remembrance of the day of the week Christ was crucified. In today's world of instant gratification, going for 24 hours consuming only water can seem daunting. Having successfully practiced this discipline during a number of Lents in the past, I must admit that one experiences hunger to an unfamiliar level, but a healthy human body has no problem adapting to a day without calories. (Fasting must allow drinking water and should not be done by young children, pregnant women, those with certain chronic illnesses, among others. Please consult a physician before adopting a complete fast.) In fact, fasting people may notice a significant change in body metabolism as the body naturally adjusts to minimize energy consumption. Of practical concern in adopting a complete fast, are secular needs that are difficult to predict, such as business or social occasions centered on eating.
Just as the logistics of fasting vary widely, so do the motivations for adopting a fast. Nancy Leigh DeMoss, in her post about Lent on February 22, 2012, talks about 'fasting the flesh to feast on Christ', an appealing concept:
"... many Christians observe Lent as a meaningful way of meditating on the sufferings of Christ on our behalf. They choose to deny their flesh as a daily reminder that Christ died and rose again to deliver us from slavery to sin and self.
"... there is value in taking such an extended period of time to clear out the clutter that accumulates in our hearts, to say 'no' to things that may have become too important to us, and to cultivate greater love for Christ." (

The Prayer Foundation (

Fasting in remembrance of or identification with Christ's trials in the wilderness are beautifully framed by Fredrick Buechner:
"Romantic love is blind to everything except what is lovable and lovely, but Christ's love sees us with terrible clarity and sees us whole. Christ's love so wishes our joy that it is ruthless against everything in us that diminishes our joy. The worst sentence that Love can pass is that we behold the suffering which Love has endured for our sake, and that is also our acquittal. The justice and mercy of the judge are ultimately one." (

May Christ's ruthless love draw you close and justify you before God.
