PBS - FAT: What No One Is Telling You
http://www.pbs.org/wgbh/takeonestep/fat/index.html
As humans we only have two desires - to find food, and to procreate. You cannot override the urges of those two basic human/animal needs.
There are 20 - 30k functions in the body - about 400 so far have been found to handle simply eating and burning energy.
We make about 100 - 200 decisions about food every single day.
Just 75 years ago we faced famine in this country. Our entire food situation has changed and we as a species has not yet learned to adapt to this new found commercialization of food sources available any time of the day.
Michael Gershen is a doctor of the gut. He believes there is neurochemical systems that involve just the gut and it is technically our second brain.
It can literally cause depression and similar emotional reactions just like our brain on the top of our body.

(Not from movie) “We’re learning an enormous amount from surgery, even though surgery itself is used infrequently,” Kaplan said. Doctors used to think weight-loss surgery worked by making the stomach smaller, but they have found
evidence that the surgery actually changes physiological mechanisms in the body that eventually determine whether or not a person gains weight, he said.
