First Wesley voices his concern that Methodists are not fasting like they did at one time:

14. It would be easy to show, in how many respects the Methodists, in general, are deplorably wanting in the practice of Christian self-denial; from which, indeed, they have been continually frighted by the silly outcries of the Antinomians. To instance only in one: While we were at Oxford, the rule of every Methodist was, (unless in case of sickness,) to fast every Wednesday and Friday in the year, in imitation of the Primitive Church; for which they had the highest reverence. Now this practice of the Primitive Church is universally allowed. “Who does not know,” says Epiphanius, an ancient writer, “that the fasts of the fourth and sixth days of the week” (Wednesday and Friday) “are observed by the Christians throughout the whole world.” So they were by the Methodists for several years; by them all, without any exception; but afterwards, some in London carried this to excess, and fasted so as to impair their health. It was not long before others made this a pretence for not fasting at all. And I fear there are now thousand of Methodists, so called, both in England and Ireland, who, following the same bad example, have entirely left off fasting; who are so far from fasting twice in the week, (as all the stricter Pharisees did,) that they do not fast twice in the month. Yea, are there not some of you who do not fast one day from the beginning of the year to the end? But what excuse can there for this? I do not say for those that call themselves members of the Church of England; but for any who profess to believe the Scripture to be the word of God. Since, according to this, the man that never fasts is no more in the way to heaven, than the man that never prays. (John Wesley from CAUSES OF THE INEFFICACY OF CHRISTIANITY Sermon 116)

I wonder what he would say to us today….
