Do obese people enjoy milkshakes more than lean people?

It turns out that obese people want energy dense foods like chocolate milkshakes more than they enjoy them, reports NPR. When linked to an MRI scanner, the screen lit up in obese women before they were served a chocolate milkshake, but as they ate, "they had a 'blunted' dopamine response in the brain's reward center compared with lean people."

Therein could be the key to obesity in some people. The foods they love never live up to their expectations, so they keep eating and eating. One expert interviewed by NPR suggests that, the only way to fight an addiction to junk food is to cut them out of your diet "before pleasure responses get blunted by overeating." Cut out junk food all together? Easier said than done.

I started pound360 to channel my obsession with vitamins, running and the five senses. Eventually, I got bored focusing on all that stuff, so I came back from a one month hiatus in May of 2007 (one year after launching Pound360) and broadened my mumblings here to include all science.
