You got it wrong ( you're first statement at least). The study is saying obese women have a different neurological response to food in their brain reward centers than non obese women. I initially thought it was because hams conditioned their reward pathways into this response but the study also goes on to say lean adolescents with obese parents have the same thing going whereas lean adolescents with lean parents do not.  Before you say I'm a ham apologist, I'm not. This type of study is potentially super fucking harmful because it enables fatties while creating an illusion of removing human agency from the equation. Which is utterly bullshit, because being fat is still their choice, just a more difficult choice for some people to abandon.  Ive had a body fat percentage of over 30 most of my life and i can say u  ff8  nequivocally weight loss is a matter of will power and willingness to put in the time to learn nutrition. It's actually infuriating to me hams will use this study to justify their shit behavior and eating habits. Losing weight is relatively easy in the grand scheme of things, such caring for a dying relative while working full time and going to school.    Also before I get called a ham myself, this is what I've looked like the past 3-4 years or so. http://m.imgur.com/NBG6o88 http://m.imgur.com/N3bbUua?r
