Clement I (died 99 or 101)
“Let them, therefore, with fasting and with prayer make their adjurations, and not with the elegant and well-arranged and fitly-ordered words of learning, but as men who have received the gift of healing from God, confidently, to the glory of God. By your fastings and prayers and perpetual watching, together with your other good works, mortify the works of the flesh by the power of the Holy Spirit” – Two Epistles of Virginity, 12
Didache (The Teaching of the Twelve Apostles) (c. 70-140)
“Before the baptism, moreover, the one who baptizes and the one being baptized must fast, and any others who can. And you must tell the one being baptized to fast for one or two days beforehand. Your fasts must not be identical with those of the hypocrites.” – Didache, 7
The Shepherd of Hermas (c. 90-140)
“This fasting … is very good, provided the commandments of the Lord be observed … First of all, be on your guard against every evil word, and every evil desire, and purify your heart from all the vanities of this world. If you guard against these things, your fasting will be perfect. And you will do also as follows. Having fulfilled what is written, in the day on which you fast you will taste nothing but bread and water; and having reckoned up the price of the dishes of that day which you intended to have eaten, you will give it to a widow, or an orphan, or to some person in want, and thus you will exhibit humility of mind, so that he who has received benefit from your humility may fill his own soul, and pray for you to the Lord.
If you observe fasting, as I have commanded you, your sacrifice will be acceptable to God, and this fasting will be written down; and the service thus performed is noble, and sacred, and acceptable to the Lord.” – Shepherd of Hermas, Book 3, Similitude 5, Chapter 3
