Obviously there has to be some upper limit. I just don't know where it's going to be.

There's good news and bad news. We're definitely nowhere near being out of the woods.

We've seen an increase in obesity in men and we've seen an increase in overweight in both boys and girls.

I was particularly concerned about seeing the increase in children, because we know that children who are overweight often become obese adults.

About 17 percent of children are overweight and about a third of adults are obese.

It's during childhood that our patterns often are set. Overweight adolescents often become obese adults.
