Gluttony will never be used as reason to council someone. If someone is already a Fat-cat in the Org and they are obese, they will not change in my opinion. They more than likely have a certain mindset, a narrow view and an aversion to looking in the mirror, and the " mirror of God's word " because the truth is hard to take. Knowing and admitting the truth requires action, which is the opposite of greed and laziness. On the other hand being to harsh with people who obviously have issues with food, probably because of emotional issues, would be cruel and unloving.
They do need help to see the situation they are in. They are showing a disrespect for the gift of life. I am sure all people are different biologically, but wouldn't being obese and the stress it causes harm you just as much as any " defilement of the flesh " ? Surely it shortens your life as much as smoking, although I don't know any figures to back that up. Maybe obesity should be a DF'ing offense! Yes, there are some medical reasons, but as shows like THE BIGGEST LOSER have proven, it is mostly lifestyle choices.
One outspoken and funny ( and sometimes unpopular ) brother gave a talk concerning the " Obesity " Awake magazine. He said from stage that
" People like to say that it is in their genes, they can't help it.. Well, have you ever seen a fat person in a concentration camp!? Wait till you get thrown in prison during a time of persecution and then tell me it's in your genes.." WOW!
