Its been helping me improve my relationship with food. I used to find it hard to make myself eat, then in recent years I've been eating too much (hmm, significant correlation with finances...). Portion control is much easier when these external learned behaviours are ignored!
I grew up being forced to eat everything in the plate. Now, as an adult, I keep doing that even though I am fully aware I don't have to. The result is that I eat much more than I should.
