Such a condition threatens the body health in that it may reduce the person’s life expectancy or cause other health complications. The Body Mass Index is used is used to ascertain the obesity conditions of the body. What is intriguing about obesity is that the cases are persistently increasing around the globe. In the attempt to curb the health issues pertaining to obesity, various causes of obesity have been identified
The obesity prevalence has been attributed to taking in of excess calories. It is argued that availability of calories has been increasing. United States has recorded the highest calories per person of all countries in the world. In 1996, the amount of calories available per person was about 3654, but rose to over 3700 by 2007. During the same period, the average number of calories available per person in Europe was 3394, but rose to over 3600. In developing countries such as Asia, the amount of calories per person stood at 2648 in 2007. The Sub Saharan Africa recorded 2176 as the number of calories available per person. These levels of calorie consumption have been cited to positively correlate with increasing obesity prevalence (Neale and Hayakawa 2008).
Furthermore, the existing guidelines on nutrition have not achieved much at sensitizing people on bad dietary habits. As from 1970s to early 2008s, the obesity prevalence in United States doubled (from about 15 percent to about 30 percent). Conversely, the average of food energy consumed by the population increased. The average number of calories consumed by every woman rose from 1542 in 1971 to 1877 in 2009. Similarly, the food energy consumed per person rose from 2450 to 2618 in men. These increased calories intake were majorly as a result of carbohydrate intake, and not fat. The carbohydrates were consumed in form of sweetened beverages and chunk food (chips). Currently, they accounts for over 25 percent of food energy consumed by adults in
