Kids are fat. It's hard not to be, every junk food, candy bar and sugary breakfast cereal has a cartoon character slapped on it.

The WHO estimates 22 million children under the age of 5 are overweight worldwide.

But, even with all these fat kids running, parents in Australia don't realize their kids are overweight.

In Australia, a recent health survey reports only 7.9% of children are considered overweight by their parents, and previous data suggests the figure could be as high as a quarter of all children, ages 2 to 12, are overweight, or even obese.

The new survey, by Australian healthcare provider MBF, also found parents have a better eye on daughters, saying 10.3% of girls are obese, compare to 5.5% of boys. Meaning many boys aren't getting the weight intervention they need.

As always, experts point to the parents, saying it's incumbent on parents to embrace a healthier lifestyle for their kids. Yeah, that's clearly working.
