My experience as an Orthodox Christian in America is that the Lenten fast is pretty much the same for all Orthodox in being basically vegan. There are also restrictions around the use of oil and wine, but those tend to be not as commonly followed. In addition, for most of the year Orthodox fast similarly on every Wednesday and Friday. Of course, age and medical conditions affect this. Increased prayer and almsgiving are also part of the Lenten fast; one idea is that the money you would have spent on meat and cheese should instead go towards charity. In my experience, I haven't really found other Orthodox specifically give up a particular thing intentionally, except for incidentally in the sense of spending more time in prayer means less time for video games, for instance. :) What's most important is achieving self discipline in not being controlled by food. If we fast from meat but "consume" our neighbor through gossip, for instance, then we've missed the whole point.
