In the News: Overeating Can Throw Off Metabolism
A new study in the journal Cell found that overeating triggers a metabolic response in the brain, even when a person hasn't gained weight. The area of the brain affected is called the hypothalamus, which helps regulate appetite, feeding behavior, energy and body-weight balance.
Overeating appears to activate a brain pathway to the hypothalamus that's normally dormant, which then causes excessive caloric consumption. So it becomes a vicious cycle- you overeat, it stimulates the area of your brain that controls appetite, and then you end up eating more. If researchers can find a way to suppress this pathway, it could have an effect on the overweight and obesity epidemic in our country.
It should be mentioned that this study was conducted on mice, but the authors believe that the findings can apply to humans as well. Therefore, further studies would be needed to validate these results. In studying the brains of mice, researchers found that a high-fat or high-sugar diet also increased the activity of this pathway in the brain. Similarly, the pathway was active in the brains of mice predisposed to obesity.
Scientists are learning more and more about obesity- what causes it and how to treat it. Maybe someday they will find the "magic cure", but for now, sticking with a healthy diet and regular exercise is the proven way to take weight off and keep it off long term. Don't you think?

Thanks for sharing. - 10/9/2008 10:12:55 AM
I think in America, many of us have a very unhealthy relationship with food in general.. and I know that I am one of those people! But, I'm really working on it. It's interesting to "diet" and not think of food as the "enemy"...but rather as a tool to fuel and strengthen your body.
I think a healthier relationship with food in general leads to a healthier YOU!
And all those enormous restaurant portions really have to go! What a skewed visual of what a "portion" is!!! So we OVER eat, and train ourselves to over-eat! This actually doesn't shock me.
Thanks for another wonderfully informative article! - 10/9/2008 7:41:00 AM
Great.... so take away the responsibility and it solves everything? I understand there are exceptions, but shouldn't we be willing to accept that we choose to overeat and learn to control ourselves? - 10/9/2008 7:09:57 AM
And so the idea that the stomach is taught to stretch is not that far ... well, stretched! We are teaching our babies to overeat! THEN they tell you to 'burp' the baby and feed it more. Hm, wouldn't that burp indicate fullness? And if you are 'demand feeding' (as I did with DS#2) yeah, they eat every 2 hours and 'only' about 3 or 4 ounces tops. But this crud about feeding them on YOUR schedule, every 4-6 hours - NOT letting their body or their metabolism maximize. - 10/9/2008 6:36:35 AM
