Weight really has very little to do with biology, and nothing to do with psychology. It is a simple matter of how much the earth's mass bends space-time - the more mass we eject of the earth, the less bent space-time will be in the vicinity, the less we'll all weight.

It really is the simplest weight loss method possible, it will work for everyone living on the planet at once, and the article presents it (and its difficulties) quite clearly - not sure why you'd go off topic by talking about biology and psychology.
