Overeating Tied To Changes In Brain Chemistry

October 5, 2010 by  

Overeating tied to changes in brain chemistry  The obesity epidemic is putting a great deal of strain on the healthcare system, costing the nation billions of dollars each year. Additionally, the number of deaths due to obesity-related health problems are rising at a rapid rate.

New research suggests that brain chemistry changes in overweight individuals may be partly to blame for the epidemic, which is spiraling out of control.

Researchers from the University of Texas, Austin found that overweight and obese individuals have fewer dopamine receptors. These are responsible for pleasure responses in the brain to external stimuli, including food. A lack of receptors means that individuals must eat more food to feel satiated.

The findings help explain why it can be so difficult for overweight individuals to cut back on portion sizes and limit their food intake.

"These results will be important when developing programs to prevent and treat obesity," said Eric Stice, who led the study. "This may explain why obesity typically shows a chronic course and is resistant to treatment."

Stice believes that understanding the underpinnings of the disease could help doctors develop more effective treatments for obesity.

    How long do we have to wait until the White House duo feels like being responsible? If healthcare is an idea whose time has come, then it is far beyond irresponsible for the White House herd to let our food producers and those corn-based sweetener whores put whatever they want in this and that. Where are the FDA pimps? Where are the AMA and our healthcare pros?
    Once again, Herr Obummer wants it both ways. Sorry. No can do, dude. Either you’re responsible, or you’re just another hack, paid-for shill for those who specialize in total control and easy riches.

    I’m not obese, but even if I were, I’d say, “KEEP THE GOVERNMENT OUT OF MY LIFE!” That includes food, tobacco and alcohol choices.

    The real deal here is simply to have public schools teach nutrition a LOT more than they do hoaxes like Global Warming and revisionist history. They should also teach parenting although the wacko socialists would ruin that too because character/values/tough love/common sense are not their strong points.

    Parents buy the food but parenting has tanked due to the liberal (aka secular socialist)
    culture. Now we have the gov-meant trying to be parents. NOT good. History should teach us that.

    Notice how the welfare crowd has such a huge percentage of 200-250 pound women.
    About half of pre-teens are overweight. Thanks, parents. Thanks public schools.
    Maybe its a new “right”…or maybe the are “victims”…lol.
    So what is the penalty for being 100 pounds overweight?
    The taxpayers via nationalized health care will pay the tab.

    Most school gave up a tough daily P. E. program long ago. Why has that not returned?

      Doug – I’ve wondered what happened to those PE programs myself. I remember when JFK had initiated more PE programs for the schools back when I was a kid – whatever happened to those programs – how did this become unimportant in schools -

    The ‘bad for us’ food is the cheapest and carb loaded which is one reason there are obese people with low incomes. The PE programs were cut back several years ago, along with a lot of after school sports programs, because it took teachers to run the after school stuff, and that’s not free. Lord knows, it’s too much anymore for most teachers that I see to donate a little extra time for anything after school. Here is Florida, we even have an ‘early release’ day every other Wednesday. The kids go nearly 1/2 a day because the teachers have to plan and learn and we have to pay them to do that and take away the education time from the kids. Our kids learn one heck of a work ethic from teachers. (I know there ARE good ones too) Most don’t want give the kids what they need, let alone anything extra. The rest of the problem is the administration. I do admire the prime riverfront property that houses our schoolboard administration though. I just don’t get the ‘greedy gotta have everything, me world’ we live in right now. I’m an RN, and no one pays me for the continued education and planning that I have to do to keep my license and education up to date. Sorry for the soapbox, but I’m so disgusted with all of this. I just pray for a productive November!
