Children seem to like consuming a lot of favorite foods such as sugary snacks, chips,...when having leisure time or day-offs at home. At school, because of having a little time to relax, they usually tend to eat lots of fast food, chips or biscuits. All bead habits make children obese step by step. Another reason contributes to this problem is unhealthy lifestyle. In fact, the more children spend time sleeping, the lazier they become day by day. Moreover, they are to glued to TV programs all the time without caring about surroundings. To make it worse, they rarely move around and help parents do household chores. Furthermore, during short break times at school. they only sit their positions instead of engaging in outdoor activities, playing games or sports with peers.
