What denominations don't believe in fasting? And Why?

There is a question on here about the importance of fasting. But this is different because I want to know what denominations don't believe in fasting and why they think that its not important. I personally have great faith in fasting and in the power of fasting such as found in Mark and Matt, when the 12 have tried to cast out a devil but failed. > Mark 9:28-29, 28, (end of verse)...Why could not we cast him out? >29, And he said unto them, This kind can come forth by nothing, but by prayer and fasting. > >Matt 17:21 Howbeit this kind goes not out but by prayer and fasting. Which is a clear example of where the disciples could not do something unless they fasted and prayed for the power to do it first. Edit: Changed as per the comments.
