The Iowa Winter Games are getting underway, and they include a competition anyone can join, athlete or not. The big weigh-in is today, kicking off an event titled “Lighten up Iowa.” Winter Games director Jim Hallihan says sponsors of the games are being encouraged to hold mini competitions within the ranks of their own workersThe teams will step on the scale again at the end of six months see who’s lost the most, with help from health department tips on exercise and diet. Hallihan says a couple of dozen teams are signed up, and says the serious message is how fighting obesity and complications like diabetes and heart disease could not only let more people join in the games but could add years to their lives.
