As we are drawing close to the end of Lent this year, thoughts about the importance and usefulness of fasting are legitimate .
This article in Christianity Today argues that, according to neuroscience, fasting is doing much more to us than to have an impact on just the body or the spirit.
Here is a quote:
Neuroscience sheds light on how fasting and other spiritual disciplines work by training our subconscious mental processes. We think of ourselves as entirely the activity of our conscious thoughts. In reality, our brain has thousands of sub-conscious processes going on all the time. These processes are often pushing and pulling different ideas, concerns, or cravings into our consciousness. What this means is your conscious self is far less in control over who you are and what you do than you realize. “We are not the ones driving the boat of our behavior,” says neuroscientist David Eagleman. “Who we are runs well below the surface of our conscious access.”
Fasting can train and shape these processes, giving us the ability to exert control over other desires. One study found that students who intentionally practiced good posture for two weeks showed significant improvement afterward on measures of self control. The ability to control our relationship to food is, of course, one of the most difficult of the disciplines. Self control is like a muscle; it can be exhausted by overuse, but it can also be strengthened with exercise.
