I really don't understand what you mean by this. Specifically "block unhappiness".
I probably used a bad phrase....I'm sick today. IMO...humans have a dual nature..a physical nature and a spiritual nature. People seek feel good happiness for the biological.. and value based happiness for the spiritual. You don't have to believe in my God or God at all to believe that humans have this non-physical nature either. Usually when people try to substitute feel good happines for value based happines they run into problems.
Usually when people eat themselves to death there is something they either
want to think and feel or something they
don't want to think or feel. Certain foods are not "bad". At least imo..nothing material can be immoral or "bad". You are not a bad person for eating a piece of cake any more than a piece of cake can be "bad".
Therefore, if you died with Christ from the basic principles of the world, why, as though living in the world, do you subject yourselves to regulations— 21 “Do not touch, do not taste, do not handle,” 22 which all concern things which perish with the using—according to the commandments and doctrines of men? 23
These things indeed have an appearance of wisdom in self-imposed religion, false humility, and neglect of the body, but are of
no value against the indulgence of the flesh.
Someone who does not address the non-physical reasons for eating themselves to death...even though it seems wise to diet the way someone would who is not in love with food..it will do them no good..it's only temporary. They are not addressing the root cause. The reasons xtians might fall into this category so much is because they tend to be too busy looking at other people's lives and not dealing with their own lives. I'm just guessing though. Who knows.
