Prior studies have shown that highly desirable foods, perhaps a cheesecake or pie, can trigger pleasure centers in the brain. But what’s new about this research is that it shows that even when people are unaware of what they’re eating, the intake of fast-digesting carbs can activate parts of the brain associated with pleasure, reward and addiction.
To evaluate this, Dr. David Ludwig, director of the obesity prevention center at Boston Children’s Hospital, and his colleagues conducted brain scans in 12 overweight men after they consumed two different kinds of test milkshakes.
Uh huh. And then this:
As , a professor of clinical pediatrics at the University of California, San Francisco, points out, this research can’t tell us if there’s a cause and effect relationship between eating certain foods and triggering brain responses, or if those responses lead to overeating and obesity.
“[The study] doesn’t tell you if this is the reason they got obese,” says Lustig, “or if this is what happens once you’re already obese.”
Right. And I’m sure it would be impossible to run the same set of tests on men who were of ideal weight, right? Because if they did that, they might upset the low-fat, calories-in, calories-out, eat lots of carbs applecart so popular among junk scientists masquerading as honest nutritionists.
