    Putting desire on a budget: dopamine and energy expenditure, reconciling reward and resources. - PubMed - NCBI

    Abstract

    Accumulating evidence indicates integration of dopamine function with metabolic signals, highlighting a potential role for dopamine in energy balance, frequently construed as modulating reward in response to homeostatic state. Though its precise role remains controversial, the reward perspective of dopamine has dominated investigation of motivational disorders, including obesity. In the hypothesis outlined here, we suggest instead that the primary role of dopamine in behavior is to modulate activity to adapt behavioral energy expenditure to the prevailing environmental energy conditions, with the role of dopamine in reward and motivated behaviors derived from its primary role in energy balance. Dopamine has long been known to modulate activity, exemplified by psychostimulants that act via dopamine. More recently, there has been nascent investigation into the role of dopamine in modulating voluntary activity, with some investigators suggesting that dopamine may serve as a final common pathway that couples energy sensing to regulated voluntary energy expenditure. We suggest that interposed between input from both the internal and external world, dopamine modulates behavioral energy expenditure along two axes: a conserve-expend axis that regulates generalized activity and an explore-exploit axes that regulates the degree to which reward value biases the distribution of activity. In this view, increased dopamine does not promote consumption of tasty food. Instead increased dopamine promotes energy expenditure and exploration while decreased dopamine favors energy conservation and exploitation. This hypothesis provides a mechanistic interpretation to an apparent paradox: the well-established role of dopamine in food seeking and the findings that low dopaminergic functions are associated with obesity. Our hypothesis provides an alternative perspective on the role of dopamine in obesity and reinterprets the "reward deficiency hypothesis" as a perceived energy deficit. We propose that dopamine, by facilitating energy expenditure, should be protective against obesity. We suggest the apparent failure of this protective mechanism in Western societies with high prevalence of obesity arises as a consequence of sedentary lifestyles that thwart energy expenditure.

    I wonder if increased levels of Food Stamps and Government Welfare correlate with more obesity. Wouldn't be surprised. That's kinda what this study is related to, correct?

    i havent read full text of the study, the connection between dopamine and metabolism and obesity was my main reason to look at it.
    but your point might be correct.

    That's kind of what I mean though. There is a (desire -> energy expenditure -> pleasure reward) dopamine process chain that is naturally supposed to occur. If you don't have to utilize any energy to procure food (because Santa Claus gives it to you) then that chain is broken and dopamine levels fall (or the brain get less sensitive to it or something) because there is no need for it. I haven't researched this in a while so forgive me if I am off.

    It's the same thing with porn. There was a website with good info about Porn Addiction (yourbrainonporn.com). I think there is stuff on Dopamine, obesity, and hormones that relates to your post. It's pretty interesting.

    it says more dopamine makes you burn more calorie.
    and the site you mentioned point to the fact that porn stimulate dopamine secretion in a bad way and also makes body less sensitive to it,and by this mechanism the person becomes less motivated for life and more positive activities.
    i might be wrong,i havent understand it it well yet.
    but even with example of porn and dopamine secretion by watching that you might still get benefit of dopamine..?!

    I guess in the short term? As with most stimulus in life, you begin to get desensitized to it (psychologically I guess?) I reread your original post and I have to say though: I know for myself drinking heavily promotes consuming tasty food lol. I always thought it was because of dopamine but maybe not.

    I have a friend who is addicted to drinking and porn at the same time. He like, can't enjoy doing one with having the other. Now that is seriously frying out your dopamine pathways. Holy Cow. Probably worse for you than heroin.

    The correlation is negative. Social democracies have a far healthier and leaner populations.

    Social democracies have Healthier and leaner populations as compared to what? Impoverished Socio-economic groups in USA that happen to receive social welfare also have high incidents of obesity and diabetes.

    That would be reasonable if t were true that the US were a social democracy, but I never cease encountering posts from affronted US citizens informing us all that the US is not a democracy- it is a republic. So there goes that argument.
    Quite apart from that the only food (or food substitute) that is affordable on low incomes in the US is take away.
    Additionally those who are employed, with incomes just above the social welfare levels generally have to work 2 jobs to maintain that income, and as a result really have no time for cooking.
    It is that extreme income situation that defines the US as not a society with any but the most marginal level of social welfare.
