Obligated fasting in Christianity Is there any Christian denomination which obligates its believers to fast (no drink no food) as the bible mentioned and in Jewish practice? I've never heard of obligated fasting in Christianity but I want to ensure it.
I know that there are different interpretations to the mentioned bible, but I just wanted to point out this place rather than discussing the interpretations. Just want to know if such tradition exists anywhere in Christianity world.
A similar question What denominations don't believe in fasting? And Why? mentions the following under the heading Who fasts and who doesn't?:


Both the Eastern Orthodox and Roman Catholic churches have required fasting periods for their members, as shown by the links.

Members of the Church of Jesus Christ of Latter-Day Saints are encouraged to fast for the first Sunday of every month, which they call their fast and testimony meeting. Instead of speakers, members come up to the microphone and bear their testimony about the truthfulness of their experiences in the Gospel [per Gilbert LeBlanc]

For a scriptural viewpoint, the Jehovah's Witnesses article What Does the Bible Say About Fasting? under the heading Is fasting required for Christians? supplies the following:

No. God required the Israelites to fast on Atonement Day, but he eliminated that observance after Jesus permanently atoned for the sins of repentant people. (Hebrews 9:​24-​26; 1 Peter 3:​18) Christians are not under the Mosaic Law, of which Atonement Day was a part. (Romans 10:4; Colossians 2:​13, 14) Therefore, each Christian may decide for himself whether to fast.​—Romans 14:​1-4.
Christians recognize that fasting is not the focus of their worship. The Bible never associates fasting with happiness. In contrast, true Christian worship is marked by joy, reflecting the personality of Jehovah, “the happy God.”​—1 Timothy 1:​11; Ecclesiastes 3:​12, 13; Galatians 5:​22.

Going by what Romans 14:​1-4 says, the decision would be up to the individual whether to fast or not. The article does give additional information on fasting that you may consider.
On a personal note, I have fasted both for dietary and spiritual reasons. As for the spiritual, I fasted during the anniversary of Christ's death to focus more on the spiritual than the physical.
