My husband knew several very large sisters that were publicly reproved for gluttony. The congregation had regular get together bring-a-dish dinners. I guess they really could "put on the feed bag". A visiting speaker was shocked by the size of the sisters and the amount consumed, so that's where the counseling started and progressed.
Could you imagine the committee meeting? "I swear to God Brother Elder I'll go on my diet tomorrow! Sniff, Sniff."
