Here’s a New Year’s resolution you only have to stick to for a MONTH. According to several studies, having a “dry January” where you don’t drink any alcohol can have a huge impact on your health.

A study in 2013 had “normal drinkers” stop drinking for one month. They lost an average of 3.5 pounds . . . were less likely to develop diabetes . . . and had lower cholesterol levels.

They also slept better . . . found it easier to concentrate . . . and lowered the amount of fat in their liver by an average of 15%. Which is important, because a fatty liver can lead to liver disease.

And a new study found that not drinking for a month can actually change your drinking PATTERNS too.

850 people agreed to stop drinking for one month. And six months later, the ones who followed through with it were still drinking significantly less than they did before they took part in the study.

Only about two-thirds of them actually made it a month without drinking though. The rest of them couldn’t do it.
