"Is gluttony a sin?"

What do you think, should gluttony be address from the pulpit on Sunday morning like every other sin? Gluttony is too crave food to the point that it kills us which is a sad thing.

1. Gluttony: a person who eats and drinks excessively or voraciously.
2. a person with a remarkably great desire or capacity for something:
3. a gluttony for work; a gluttony for punishment.
   

What I found so shocking is who are at a particularly high risk are black American women. Now I know There are legitimate medical reasons for being overweight: thyroid problems, medication side effects, etc. But face it: most of us are overweight because we simply eat too much food and exercise too little.

Emotional eating is an idol; we use food to self-medicate and feel better before we think to go to God with our concerns. I've heard pastors who preach vehemently against homosexuality and abortion, but who have never uttered a single world against gluttony, which is actually one of the seven deadly sins. Why are we ignoring this serious issue?

I figure it's easy to rail against sins committed mostly by those outside the church. Most churches don't have a significant numbers of gay people in the congregation, and so it's easy for us to pass judgment on them because they're "those other people." However, most churches do have a lot of overweight members; but for a pastor to challenge them would alienate people, thus shrinking tithes.

Question:Why is gluttony more accepted or at least tolerated over other sins?
