You know your friend who always seems to get you into trouble when he’s drunk? Well, here’s another reason to hate that guy. Recent research out of Finland suggests that a gene mutation that causes people to be aggressive when they’re drunk may also protect them against obesity and related risks like diabetes. That’s right: Your crazy drunk friend is going to outlive you… assuming he doesn’t get himself killed first.
The study, conducted at the University of Helsinki and published in the Journal of Psychiatric Research, looked at 98 Finnish men between the ages of 25 and 30 who had all been diagnosed with antisocial personality disorder. The researchers then looked for a point mutation in a gene of serotonin 2B receptor, which has been shown to cause impulsive behavior, especially after a little liquor. What they discovered is that those who had this “aggressive drunk” gene had a lower BMI and higher insulin sensitivity, which in turn creates a lower risk for type 2 diabetes.
“It is fascinating to think that this receptor mutation which has been passed through the chain of evolution would impact both the brain as impulsive behaviour and energy metabolism,” University of Helsinki psychiatrist and lead author Dr Roope Tikkanen said in a press release.
