Additionally, many Christians may choose to practice vegetarianism or veganism as their Lenten sacrifice during the period of Lent.[19][20] Prior to the 6th century, Lent was normatively observed through keeping the Black Fast for forty days, with the allowance of one vegetarian meal with water after sunset.[21][22]

^Robert Eisenman (1997), James the Brother of Jesus, p. 240 – "John (unlike Jesus) was both a 'Rechabite' or 'Nazarite' and vegetarian", p. 264 – "One suggestion is that John ate 'carobs'; there have been others. Epiphanius, in preserving what he calls 'the Ebionite Gospel', rails against the passage there claiming that John ate 'wild honey' and 'manna-like vegetarian cakes dipped in oil. ... John would have been one of those wilderness-dwelling, vegetable-eating persons", p. 326 – "They [the Nazerini] ate nothing but wild fruit milk and honey – probably the same food that John the Baptist also ate.", p. 367 – "We have already seen how in some traditions 'carobs' were said to have been the true composition of John's food.", p. 403 – "his [John's] diet was stems, roots and fruits. Like James and the other Nazirites/Rechabites, he is presented as a vegetarian ..".
^James Tabor, The Jesus Dynasty p. 134 and footnotes p. 335, p. 134 – "The Greek New Testament gospels says John's diet consisted of "locusts and wild honey" but an ancient Hebrew version of Matthew insists that "locusts" is a mistake in Greek for a related Hebrew word that means a cake of some type, made from a desert plant, similar to the "manna" that the ancient Israelites ate in the desert on the days of Moses.(ref 9) Jesus describes John as "neither eating nor drinking," or "neither eating bread nor drinking wine." Such phrases indicate the lifestyle of one who is strictly vegetarian, avoids even bread since it has to be processed from grain, and shuns all alcohol.(ref 10) The idea is that one would eat only what grows naturally.(ref 11) It was a way of avoiding all refinements of civilization."

However, most people, Catholic and otherwise, don't realize that many Catholic monastic orders such as the Franciscan nuns, Trappists, Trappistines, Carthusians and Cistercians are strictly vegetarian. Carmelites and other communities that follow the Rule of St. Albert similarly restrict themselves to a vegetarian diet except in the case of elderly and infirmed members. Eastern Catholic monks and nuns also completely abstain from meat—some even abstain from dairy and seafood also—for the sake of mortification, prayer and asceticism.

^Butler, Alban (1839). The Moveable Feasts, Fasts, and Other Annual Observances of the Catholic Church. Dublin: James Duffy. p. 144-146. The primitive Christians in Lent broke their fast only after sunset, and then usually only with herbs, roots, and bread. At least all were obliged to abstain not only from flesh meat, but also from fish, and whatever had life; also whatever is derived from flesh, as eggs, milk, cheese, butter, according to the ancient canon. Likewise from wine, which in the primitive ages was no less forbidden on all fasting days than the use of flesh meat itself ... Some mitigations were introduced in part of abstinence in the sixth century ... Fish was in the same age allowed, but not of the dearer and more dainty kinds.
