As pointed out above, sexual attraction is about as hardwired in us as anything, but "I was genetically predisposed to do it" isn't (yet) a credible excuse for affairs or harassment. Unless we lessen responsibility for any behavior that involves lack of discipline in general, I don't understand why overeating deserves special consideration. Maybe celibate monks are a myth.
Regarding the CBC news article, doesn't the reported result conflict with the "(calories in) - (calories out)" idea of weight management? "Inactivity does not lead to fatness" suggests that my activity levels shouldn't affect how much I can eat before I start gaining weight. In other words, if I can eat four thousand calories per day without weight gain while adhering to a daily exercise regimen, I should be able to eat the same four thousand calories per day while completely sedentary without experiencing weight gain. That doesn't match my experience.
