Mankind can't afford this
Ok. I am a Jain from India. There are some practices that we are supposed to follow which are strictly based on science.
Firstly after we finish our meal we are supposed to rinse our plates and drink it. One can only do this if no food is left in the plate or one has not overstuffed oneself to the brim. Advantages are 3 fold. It is a whole lot healthier to leave your stomach a little bit empty. Cleaning up after the meals is a whole lot easier. There is no waste of food when many in the world go hungry.
BTW in Germany if a person leaves food in ones plate or serving bowls he / she is liable to a fine. May even get arrested !
