The days will come when the bridegroom is taken away from them, and then they will fast.

Strictly speaking, G3522-fast has to do with food and drink. Metaphorically, it can be expanded somewhat. Corinthians 7:

5 Do not deprive one another except with consent for a time, that you may give yourselves to fasting and prayer; and come together again so that Satan does not tempt you because of your lack of self-control.

Are Christians required to fast today?

There is no commandment requiring a Christian to fast. However, you want to fast is up to you. On some special occasions, it is a good idea, e.g., during Lent. Let your conscience guide you in this.
