Research shows brain's addiction to processed carbs is real

A new study gave 12 obese and overweight people milkshakes. All had the same number of calories, the same sweetness and the same taste, but one of the two types of milkshakes had high-glycemic carbs, while the other had low-glycemic carbs.

As predicted, the volunteers got a sugar rush (surge in glucose levels) after drinking the high-glycemic milkshake, then crashed (in terms of energy) four hours later. During the crash in blood sugar levels, the volunteers became overwhelmingly hungry and researchers could see (using fMRIs) that they had intense activity in the nucleus accumbens - the part of the brain that deals with addictive behaviors.

Here's the summary:
