The study was carried out by researchers from Washington University in St. Louis, Missouri and focused on seeing if there was a link between having a family history of alcohol abuse or alcoholism, and obesity.
Researchers analyzed data that came from two different surveys that involves alcoholism.
The surveys were conducted through the 1990s as well as through the 2000s and involved over 75,000 people in total.
Researchers found that those who had a family history of alcoholism were far more likely to be obese than those who did not.
The belief is that this is due to the fact that the addiction may be passed odwn in the family.
The only difference is that the new entrants into these families are becoming addicted to junk food more than they are addicted to alcohol.
As the years went by in the study, they found that the more recent adults with a family history of alcoholism were more likely to suffer from obesity than those from the early 1990s.
The family history of alcoholism and obesity are more directly linked now because the food that is available today has more calories and more fat than the food some years ago.
Still, the addictive nature between these foods and the brain is similar to the addiction that is seen from alcohol.
The study has been published in the journal Archives of General Psychiatry.
