Since you brought it up …

yesterday was Meatfare when we Byzantine Catholics, and Orthodox, ate meat for the last time til Pascha. Next Sunday is Cheesefare when we eat dairy and eggs, olive oil and wine for the last time. There are some exceptions, like the great Feast of the Annunciation when fish, oil and wine are allowed, and generally olive oil and wine are allowed on weekends. There’s a good explanation of the
guidelines in the GENERAL RULES OF THE LENTEN FAST section
here. Fasting (abstinence) is meant to be done with the counsel from one’s spiritual father/adviser. Lent for us begins on Monday after Forgiveness Sunday (Cheesefare), rather than Ash Wednesday. (I believe Fr Loya talked about Meatfare and the progression moving into Great Lent on his wonderful
Light of the East radio program this past Sunday 2/7, but that program isn’t uploaded yet.)
