My two cents. I prefer analogy with sport. Say you choose running and pick 10k distance. What might be the goal? 50min, 40min, 30min? Say you pick 50min, if you are out of shape and did not do sport in your life - it will take you 6-9 months. You will have to train 3 times a week, probably you won't hire a couch, your body won't be ready, hence you will make many mistakes and will have quite high chances to injure your self and quit. What I want to emphasize - to succeed you have to start loving the process and blend the process into your lifestyle.
I see very clearly how the goal oriented approach fails for loosing weight while the only effective thing to do is eat less.
