Gluttony for pleasure is very rare. It is an addiction, caused mostly by emotional problems. It is NOT a lack of self control. When I was a teenager, I was seriously underweight. Now I have diabetes, genetic, and see how the difference in blood glucose regulation affects my appetite. I am mostly extremely ravenous or I have no appetite. This is Middle Ages thinking. Where are the supports to get help?
I would be stunned if there were no fatties at Bethel. Eating disorders can be managed. Overeaters Anonymous helps many with the concept of a Higher Power termed God. Witnesses can't do Twelve Step. So what help does a sufferer find?
