Studies show that since the early 1970s, the percentage of both children and adults who can be characterized as overweight has doubled. According to a survey by the Public Health Agency of Canada in 2007, self-reported rates among children from age 12 to 17 of obesity were 2.9% for girls and 6.8% for boys. It is interesting that children who have problems with weight are more likely to become overweight adults. In a study by Lauren Marcus and Amanda Baron (n.d.) it was found that obesity begins in childhood for 30 persent obese adults. Sientists give many reasons for obesity, but the main three causes of childhood obesity are genetics, lack of activity, and children nourishment at school and at home. It is proven by scientists that genetics plays an important role of human beings.

Studies show that some ethnic groups have more prerequisites to be obese or are more defenseless to obesity-related disorders; moreover, a high body mass index could be associated with some genes (Denis Daneman and Jill Hamilton, 2010).

When a child has both parents who are obese, there is an 80 percent or less chance of being obese. No doubt, genes affect how a person’s body stores fat and how it is distributes through...
