Is Fasting 'Just Another Diet'?

Okay I'll admit it, losing a couple pounds over 24 hours is a definite motivator when I fast, but I have noticed other benefits as well. 

A glass of water can help relieve hunger when fasting.

The period I choose begins after breakfast, then I just have liquids until lunch the next day. I like this timing because it only requires one night of fasting instead of two. Sometimes I barely feel hunger while fasting and it passes quickly, while other times I may get a little shaky. Eventually there's a point when my body begins to convert more stored energy from itself instead of food. Skipping only one meal doesn't seem to get me to that point, and often just makes me eat more the next meal. The longer fast is needed, and here are other benefits I notice:

• Even though I only lose a couple pounds fasting, it seems to improve my metabolism for a few days afterward.
• During the fast my appetite settles down, and I realize I am not a 'slave' to food.
• Fasting also shows me how dependant I am on eating for reasons other than hunger. Do I snack to cheer myself up while working? How do I use the extra time while fasting, do I enjoy other things in life when food is absent?
• Fasting allows time for my body to recover from food sensitivities. Apart from this, a break from genetically modified or artificial foods and preservatives might benefit anyone.
• Fasting improves my weight and appearance.
• In addition to my own health, I sometimes dedicate a fast to 'a cause'. To avoid the "I'm fasting so you owe me" attitude, I may instead ask God if there is something He would like me to fast on behalf of.*

I definitely don't fast perfectly, or as regularly as might be best. Sometimes to coax myself, I allow tea in addition to water. Or I may promise myself something special for lunch the next day, as an incentive. For me it's about the willingness to try, and then see what happens.**

*(Isaiah 58:6 NIV) “Is not this the kind of fasting I have chosen: to loose the chains of injustice and untie the cords of the yoke, to set the oppressed free and break every yoke?"

**(Matthew 6:16-18 NIV) 16 “When you fast, do not look somber as the hypocrites do, for they disfigure their faces to show others they are fasting. Truly I tell you, they have received their reward in full.17 But when you fast, put oil on your head and wash your face, 18 so that it will not be obvious to others that you are fasting, but only to your Father, who is unseen; and your Father, who sees what is done in secret, will reward you.

Note: I am not a medical professional and this is just my personal experience with fasting, not a recommendation.
