Fat", that's the name of a new report on the future of America's
waistline. The study conducted by the Trust for America's Health
and the Robert Wood Johnson Foundation uses government data on
obesity to make predictions about our weight in coming years.
This year Mississippi topped the Centers for Disease Control
list of chunkiest states, with a nearly 35-percent adult obesity
rate. But according to the new report, by 2030, 13 states could
have obesity rates over 60-percent. Some experts question the
accuracy of this weighty research saying it is difficult to
predict future weight trends accurately. The report proposes to
put America on a weight-loss challenge saying if all adults
reduced their body mass index by 5-percent, states could save
billions of dollars on health care.
