There's good news and there's bad news about the state of obesity in the United States. The good? Obesity rates have essentially remained steady over the past year. The bad? They are still very, very high.

That's the overall takeaway from the annual report on obesity released this week by the Trust for America's Health and the Robert Wood Johnson Foundation, which found that nationally, more than 30 percent of adults are now obese. Additionally, nearly 17 percent of 2 to 19 year olds and more than 8 percent of children ages 2 to 5 are obese.

"Efforts to prevent and reduce obesity over the past decade have made a difference. Stabilizing rates is an accomplishment," said Jeffrey Levi, executive director of TFAH. "However, given the continued high rates, it isn't time to celebrate. We've learned that if we invest in effective programs, we can see signs of progress. But, we still haven't invested enough to really tip the scales yet."
