Let's ruminate about gluttony

Derek over at the gospel coalition put up a thoughtful and challenging piece about gluttony last week. make sure you read it.
What is surprising is how such articles or preaching receive such flack. We can preach about sin in general terms such as idolatry. people may even accept a broadside at same sex marriage and the sin of adultery, but gluttony seems to be in a too hard basket. perhaps many preachers are afraid as Derek says because

our pastors have noticed how much closer the pulpit has moved to their own waistlines

Even so, gluttony is listed in 1 Cor 6 as a persistent sin [ habitual ] that prevents one inheriting the Kingdom of God. Even though drunkenness is perhaps put up with being preached, still gluttony seems taboo because defining gluttony seem so subjective.
And that's even without thinking of gluttony as an idol!
Something to chew the cud on eh?
