Today we see that teen or child obesity has increased in the last twenty years,and that this problem is becoming worse,but does anyone really know the different causes.We all know that obesity is caused by doing no physical activity and eating large amounts of food,but my concern is that some teens or children who are not obese are doing the same,so that tells us that obesity is controlled by the environment.So off course that tells us when parents are obese one or two means that the child has a very high percentage of becoming obese or overweight.How can we change the teens or the childs confidence or attitude so that they can be positive and start making a change by losing weight and becoming healthy,not skinny?The future will be very scary if no one will start to make a change in the eating habits.We all know that teens and children are our future and that thats why we must care.So what can teens and children do to change their lifestyle and their eating habits.Thank you for you.
