IntroductionChildhood obesity is increasingly becoming a major public health problem in developing countries, particularly in Canada and the United States. Lack of physical activity, poor nutritional choices, easily accessible fast food restaurants, and the built environment are all considered major contributors to childhood obesity. Obese individuals are at increased risk of developing high blood pressure, impaired glycemic function, and may sometimes be victims of physical and psychological abuse (Ludwig, Peterson, & Gortmaker, 2001). In Canada, the prevalence rate of obesity has increased primarily among children and adolescents (Roberts, Shields, De Groh, Aziz, & Gilbert, 2012). An estimated 19.8% of people aged 5 to 17 were classified as obese or overweight in a recent Canadian Health Measures Survey (Roberts, Shields, De Groh, Aziz, & Gilbert, 2012). However, the prevalence of obesity compared to girls was three times higher among boys. (Roberts et al, 2012). In the United States, 25% of children are considered overweight, while 11% are obese (Ludwig et al, 2001). Additionally, excessive consumption of soft drinks has been shown to negatively affect obesity rates, with the risk of becoming obese being 1.6 times higher for each soft drink in children (Ludwig et al, 2001). Although policies such as regulating food advertising to children and implementing nutrition policies in schools enjoy popular support, it is important to ask whether there is empirical evidence that these policies could be effective in achieving the desired result. What does the empirical evidence suggest and what will be enough to solve the problem of childhood obesity.
