Drugs as food
I was reading the Wall Street Journal yesterday and saw an article titled "Food may be addicting for some." Thus far I've been able to find the Archives of General Psychiatry online and ran across a synopsis of the article that was perhaps more erudite, but less helpful than the newspaper article. I then read a "psychcentral.com" review of the study.
Let's start with the newspaper. It describes a study on a small number of subjects, 39 women, who had MRI brain scans after completing a short food addiction test that was originally designed to detect people with eating disorders. Fifteen of the women had high scores indicative of potential addictive eating problems; those same women had markedly different brain scan results than the lean subjects.
Okay, let's go back a ways. Last year in the journal Nature Neuroscience, Scripps researchers found that obese rats had brain alterations as compared with lean rats. The changes in the rats' brains were similar to those reported in people who are drug addicts. In short we normally get neural (brain-mediated) rewards for "pleasurable" activities. Similar rewards occur in response to addicting drugs.
The current study started with 48 healthy young women, some of whom were thin and some fat (or as, in our world of political correctness, we now term "obese."). They were enrolled in a "healthy weight maintenance' study. Thirty-nine MRI results are reported, after the women were show pictures of chocolate milkshakes or a less enticing solution and some actually got either the milk shake or a tasteless control surrogate.
Then they had brain scans and the pattern of neural activation was much like those seen in drug addicts. Either food intake (or even viewing a photo of food) or drug use can stimulate the brains release of chemicals we find pleasurable.
"It ain't easy" for some to lose the extra weight
So what does this mean for society? Number one: not everyone can lose weight by following a deciding to diet. Number two: the omnipresent visual food ads can be detrimental to a segment of our population. Number three: I think organizations similar to Alcoholics Anonymous may be one aid to that group of the obese.
The lead author, Ashley N. Gearhardt, a doctoral student at Yale, who help devise the 26-question Food Addiction Scale, was quoted as sayying, "Some of them actually stop socializing because it gets in the way of their eating."
We've got a major problem here folks. I gained a few pounds on a 11-day trip to see old friends all of whom wanted to feed me wonderful meals. When I got home I went back to my usual eating pattern and the extra weight dropped off rapidly.
That's not going to be as easy for some and darn near impossible for others.
