In my opinion, we Catholics are pretty wussy when it comes to "fasting." I mean, on Yom Kippur my Jewish friends do it hardcore. They really don't eat. In my faith, we're just expected to cut way back. It ends up being more of a "healthy eating day." It still results in a greater consumption of food than probably the majority of people on earth eat in a day.
Anyway, my point is not to compare how other faiths would kick Catholics' butts in a fast-off, but to talk about my relationship with food on "fasting" days. The nice thing is, when I know I'll be eating less, I do something that I should do every day: Pay attention to my food. Savor it. Remind myself how fortunate I am to have nutritious food to eat.
So today's tip is: Eat slowly. Savor your food. Enjoy it. Feel thankful for every delicious bite. Taking time to thoroughly chew and taste every morsel not only increases the pleasure of eating, it aids digestion. Win/win!
