Thanks for the replies… but I’m kind of confused now… what if I go to daily Mass in the evenings at the local Roman Catholic parish? (and I’m Eastern Catholic). I can’t then fast since the morning till 7:30 pm… every day…
I thought
josephdaniel29 had the best answer in his question: “Why do you fast?”.
Luckily I’m Russian Catholic and we’re orphans without a heirarchary who have dummed down the teaching, so in my parish we simply follow our mother church-- we use the OCA translation of the Liturgy, the OCA music, the OCA wall calendar, i.e. fasting norms… As Father said one night when the next day was an evening DL and he was talking about fasting “It’s easy to fast over night!”, meaning it isn’t easy to fast all day, Fasting is always recommended to be done with guidance from a qualified spiritual father. We see that is perhaps not yet an option for you, so you’re asking here.
Personally, when I am going to Presanctified at night I eat breakfast and nothing after that until after Eucharist. If I were ill or working hard during the day I’d probably have a light and early lunch. When I am going to evening daily Mass then I do pretty much the same. Sometimes I don’t know I’m going to make it to Mass that evening and end up going. If I ate after lunch then I don’t go up for Eucharist. If I ate an early lunch, or just a late breakfast I probably do go up for Eucharist.
If you are going to daily Mass, and it sounds like that is what you are saying, and you have no real background with fasting but desire to begin to take advantage of your patrimony by adding fasting you could consider just focusing on the traditional Wed. & Fri. abstinence part of it for a while (and since it is Great Lent try eating a light and early lunch and nothing after that until Eucharist).
Back to “Why do you fast?” I highly recommend listening to
Fasting in the Byzantine Church Year with Fr. Moses of Holy Resurrection Monastery, along with
Feasting in the Byzantine Church Year, also with Fr. Moses. The juridical focus taken in the Latin Church is not the approach in the East. I think you’ll get help with this by listening to Fr. Moses. If you click on “(more info)” you can see a list of all the questions Catherine asks Fr. Moses in each of the videos.
There is much wonderful writing on fasting from the Eastern perspective. I think
Great Lent by Fr. Alexander Schmemann of blessed memory is a wonderful book, especially helpful is the section “The Two Meanings of Fasting” (pg 49). Some of the book is available on
googlebooks, but not that section any longer.
Fasting is one of the wonderful gifts of the Eastern tradition.

I hope you will give yourself the opportunity to learn more about the “Why do you fast?” part from the Eastern perspective. This is where you can find motivation for embracing joyfully elements of this tradition.
