In this June 26, 2012, photo, two overweight women hold a conversation in New York. A new poll suggests that while more than 7 in 10 Americans can correctly tick off heart disease and diabetes as obesity's most serious consequences, few Americans are aware of the lesser-known health consequences_ such as worsening some types of cancer, arthritis, sleep apnea and even infertility.  Only about one-quarter of people think it's possible for someone to be very overweight and still healthy, according to the poll by The Associated Press-NORC Center for Public Affairs Research.
