Obesity is an illness in which the sufferer has accumulated so much body fat to the point that the excessive amount of the fat has a negative effect on the person's health. Similarly, the construct that is normally used to measure obesity is the body mass. This is to the effect that whenever a person's body is at least 20% higher than recommended by healthcare providers, then the person is considered obese. In simple terms, upon a person's Body Mass Index (BMI) falling within the bracket 25 and 29.9, that person may be considered overweight on one hand. Those who have a BMI reaching 30 are on the other hand considered obese.
The BMI as the standard for measuring obesity and being overweight and as a statistical form of measurement is derived from measuring the person's height and weight. The BMI remains as the most useful way of gauging a person's healthy body weight.
The Number One Culprit in Obesity: Laziness
Laziness has been cited as the most formidable factor against sound health and the war against obesity. Taubes (344) cites the arrival of computers, television, remote controls, washing machines, video games and dish washers, as being among some of the modern convenient devices that are leading people to adopt a much more sedentary lifestyle compared to their predecessors.
Taubes (433) divulges that compared to the present, before and in the 1980s, people would walk down the road to the high street so as to reach grocers, banks, bakeries and shopping outlets. The emergence of the large out-of-town shopping malls and supermarkets has only been successful in dissuading people from using their feet, since the same use their cars to get to these provisions. In the US especially, this dependency on the car is said to be so strong to an extent that people drive even if the destination is less than or half a mile away. The fact that obesity is becoming increasingly more ubiquitous at a rate that is synchronized with technological development underscores the role these modern convenient devices play towards lack of physical activities.
Barrett (90) maintains that this above is a bad trend which is detrimental to health. This is because, the less people move around, the fewer the calories that are burnt. Apart from the details on the burning of calories, it is pointed out that physical activities have a beneficial effect on the regulation of insulin levels, by helping keep the same levels stable. Unstable insulin levels are always concomitant with weight gain, and ultimately, obesity.
James, Leach and Kalamara (75) cite the findings by the National Healthy and Examination Survey which pointed out that those who engaged in limited recreational activities were very susceptible to weight gain and obesity. This is to the effect that the amount of calories burnt is dependent on the duration, type and intensity of the activity. For instance, 1 250 pound person is bound to burn more calories when running 1 mile compared to one who runs the same distance but weighs 100 pounds.
According to Oken (126), apart from the fact that regular exercise and physical activity helps in ushering in weight loss, the same are recommended for being responsible for the elimination of body fats and the realization of lean muscles. This shows the need to engage in exercises and physical activities, in lieu of dieting alone. It is also clear that through regular physical activities and exercise, the body is able to realize effective, improved and stable control of the triglyceride and the HDL cholesterol levels. This is because cholesterol is burnt during physical activity or exercise.
The failure to engage in physical activities or exercises is also likely to bring about obesity, given that physical activities and exercises lower blood pressure and reduce the level of abdominal fat. The risk of heart diseases which is one of the landmarks of obesity is also reduced heavily by the culture of physical activities and exercise. Exercises and regular physical activities are known to be responsible for ensuring that there is good blood flow in the body. Proper palpitation and blood flow are also important in ensuring that the valves to veins and arteries are free of congestion or blockages. This is the very antithesis of obesity, given that obesity ensures that the presence of high cholesterol and body fat levels clog blood capillaries.
Taubes (82) therefore clearly shows that it is clearly a big lie to posit that there is no direct correlation between obesity and lethargy. By extension, to maintain this standpoint is to diabolically mislead the public, since it involves deceiving the same that it can afford to be lazy without suffering the consequences. On the contrary, it rings true that the culture of physical activity and continual exercise is not only important in waging war against obesity but also controlling and alleviating the dangers of asthma, osteoporosis, arthritis, pulmonary infections and chest pressure pains.
