Indiana is among a growing number of states with online efforts to help fight expanding waistlines.
In January, Indiana launched its 10 in 10 Challenge, an online program that commits participants to lose 10 pounds in 10 weeks and prods them with weekly e-mails filled with exercise and diet tips.
Proponents say online programs reach a vast audience, are relatively cheap and a quick way to let people know about upcoming fitness events and local resources.
