What are causes of obesity in children and what solutions can be offered? Children's weight has increased significantly in the past few decades. There are a number of causes behind this issue. In this essay, I will explain the reasons of this problem and propose solutions on this matter. First of all, one of the reasons that causes the prevalence of obesity among children is the popularity of fast food. This is because the children are being excessively exposed in the fast food advertisement. For example, big fast food chains such as KFC and Burger King, sell cartoon toys with food to attract more children to consume in their restaurant. As a consequence, eating too much food that rich in fat and oil would undoubtedly have a negative impact on their weight. In my perspective, what government and local authorities could do is tight the regulations and laws to forbid the number of ads that are designed to target children. Secondly, lacking sufficient physical activity could be another reason that causes obesity among children. The reason for this is that an increasing number of children are living a sedentary lifestyle, which means they spend a considerable amount of time in front of TV or computer games. To tackle this problem, parents should limit the screen time for children and encourage them to play outdoors. In addition, school should set strict rules in prohibit playing cellphone in campus. Taken together, excessive unhealthy foods ads and a shortage of exercise are the main reasons that cause prevalence of overweight or obesity among children. Government, teacher and parents should work together to curb the trend of this issue.
