Obesity and video games

Children love to play video games. They find video games very exciting and entertaining. However these video games are typically played indoors, involving little or no movement of major muscle groups in the body. Video games tend to the children of outdoor activities as well as the opportunity to interact with other children.

Video games are also less physically tiring compared to other outdoor games and therefore children are able to play them for long hours. Some children become addicted to video games and lose interest in outdoor activities. Children are naturally active and have a lot of energy. Not being able to release this energy by playing outdoors and running about could result in their becoming overweight or even obese.

Children also love to eat high calorie junk foods and snacksUnlike outdoor games and sports, playing video games does not provide children with thechance to burn these additional calories. Over time, these additional calories will accumulate in the children’s body and lead to obesity.
