http://www.washingtonpost.com/blogs...-how-much-weight-weve-gained-since-the-1960s/ The average American woman weighs 166.2 pounds, according to the Centers for Disease Control and Prevention. As reddit recently pointed out, that's almost exactly as much as the average American man weighed in the early 1960s. Men, you're not looking too hot in this scenario either. Over the same time period you gained nearly 30 pounds, from 166.3 in the 60s to 195.5 today. Doing the same comparison as above, today's American man weighs almost as much as 1.5 American women from the 1960s. At 195.5 pounds, put five American guys in a room and you've gathered roughly half a ton of manhood.
