I have only been home-brewing since November, but I worked in the beer industry for 20 years. Over those years (and thousands of beers), I gained 60 pounds.
Started working out for the first time in June and dropped several pounds, but beer and weight gain seem to go hand in hand. However, I blame bar food for much of that gain (who can't pass up wings or potato skins while enjoying a few cold ones)
I have not really gained much since November despite the fact that my home brews have considerably more calories than the large brewer lagers. However, I find that I savor fewer home brews vs. "pounding" a lot of the lightly flavored lagers. So I probably take in the same calories due to drinking fewer beers per session.
