Absolutely. There are a lot of people who get a whole extra day of kcal worth of beer in a week. Additionally people who drink a lot pretty much stop eating because they opt for the liquid lunch etc.
There is no doubt in my mind that the alcohol consumption is much more of a contributing factor to not only the obesity but also the overall decline in health wellbeing and raise in suicide/depression. Alcohol is socially accepted poison, and I feel its consumption in any amount is significantly worse for the individual than any poor diet/exercise regiment.
