WTH...
For me the article is extended past the breaking point and self-contradicting. The media will have a field day with this one touting it as another reason (actual translation: a rationalizing excuse) that we're not actually in charge of our own food destinies.
A perfect counterpoint of our abilities to override our ancient instincts are the members here that successfully dropped undesirable weight and who managed to keep it off. Hunger is transient. You'll get over it if you just give it a few minutes.
To even briefly feel that you might be a victim of your AGRP/SFO neurons would be to place yourself lower in mental capacities than these laboratory mice, who were satisfied seeing the food but who felt no subsequent drive to actually eat it. Like mirror neurons, the extensions here will be soundly refuted, hopefully sooner than later.
