Nobody said to discard the method; it must be improved on. Asking people to turn themselves into a dumb, emotionless governor, removed from the situation, isn't exactly the most helpful advice. Also, as I tried to point out, your model is flawed right from the start when you say "eat more-> gain weight". The net caloric balance is only forcing when it's negative. The conversion of excess calories into fat is not a law of physics. Now those various factors you would like to ignore come into play.
