NEW YORK (Reuters Health) - "Super-sized" fast food meals and TV time shouldn't take all the blame for the U.S. obesity problem, according to a research review published Tuesday.

Writing in the International Journal of Obesity, they argue that obesity research and prevention efforts need to look beyond the "Big Two" -- food industry practices, like beefed-up portion sizes and added sugar; and reduced physical activity from factors such as cuts in school gym classes.
