I prefer to see it not as a time to give up things, but as a time to add - making more time for prayer, reflection, reading and giving to others...

This is what Isaiah considered true fasting to be and
You will be like a well-watered garden,
like a spring whose waters never fail.
Your people will rebuild the ancient ruins
and will raise up the age-old foundations;
you will be called Repairer of Broken Walls,
Restorer of Streets with Dwellings.
I would love to be like a well-watered garden and be called a Repairer of Broken Walls :-)
