Drinking alcohol increases grazing for junk food.  

We have all had a night of debauchery in our youth where we spent the night out with friends hopping from bar to bar followed by a less than a healthy meal.  Anecdotally, we know that drinking increase poor food choices.  It just makes sense that sense that alcohol, which suppresses frontal lobe inhibition, would increase eating less healthy food choices and more yummy but unhealthy calorie-dense junk food.  We suspect this is true based on experience, but today we have research proof.
