Participants in the financial incentives group lost a mean of 5.4 lb, those in the environmental strategies group lost a mean of 2.2 lb, and the combination group lost a mean of 2.4 lb more than participants in the usual care group at 18 months.
Financial incentives may lead to greater weight loss compared to usual care, but the overall effectiveness is not significantly different.
