The American Academy of Pediatrics is suggesting children get no more than 2-hours of "screen time" each day -- meaning, computer, TV and video games combined.
The group also recommends boys walk at least 11,000 steps a day, and girls 13,000.
Researchers from the University of Iowa recently followed a group of children to assess those recommendations.
Those who did not meet these exercise and screen time standards were three times more likely to be overweight than those who did stay within the guidelines.

The stress of a cancer diagnosis and its subsequent treatment can leave a person exhausted.
But according to new research -- finding the energy to exercise may be the best way to beat fatigue.
Researchers looked at studies involving cancer-related fatigue and different exercise programs.
Patients who walked for 30 minutes, 3 to 5 days a week, reported feeling more rested and better overall.
While exercise alone can't cure cancer-related fatigue and other symptoms researchers say it should be considered as a key part of a patient's recovery along with traditional treatments.
