it would be nice if it were that easy to place the blame, but there are many, many non-drinkers who find it all too easy to gain weight. Heredity is a major factor, and eating habits in early youth tend to 'set' the body's processing mechanism.....and after all that, various forms of booze can make it worse. Exercise can help, but getting started at serious exercise when exercise is already uncomfortable takes will power.

Moderation in all things is a good start.

good luck...
