Essay On Exercise And Caloric Balance

Obesity remains an extremely serious issue worldwide. Once considered a problem for wealthier counties, overweight and obesity are now dramatically increasing in low and middle income countries (WHO, 2011). In American, the rates of obesity continue to soar. CDC (2009) recognizes obesity as a risk factor for diabetes, heart disease, high blood pressure, and other health problems. According to NHANES over two-thirds of the US are overweight or obese, and over one-third are obese (CDC, 2009). Treatment for this illness varies; it may include the incorporation of diet, exercise, behavior modification, medication, and surgery. Since there is no single cause of all overweight and obesity, there is no single way to prevent or treat overweight

For a long time, obesity has been one of the notable health concerns that America has struggled with during the last five decades .Obesity as a health concern is not limited to America alone, it is a serious concern among other affluent societies like European countries. A considerable number of Americans spend a significant amount of money trying to lose weight. Obesity become an important focus in the news items during the year 2002.According to research findings, the rate of obesity among the American was at an average of 12% in 1990 and this rate was at 23% in the year 2005(Menifield, Doty and Fletcher 83-8).

Synonymous with the growing fast food industry is the increasing problem of obesity. In addition, activity levels have decreased in conjunction with the rise in obesity. The current research has concentrated on food choices such as requiring a change to fruits and vegetables in relation to fast food, snacking or measure physical activity for weight loss and to reduce the incidence of obesity. Future weight loss programs should look at not only food restriction or activity levels but what combination is the best method for long-term outcomes in health and weight loss, and if this naturally leads to a reduction in the consumption of fast

Adult overweight and obesity have become a worldwide issue that has very dangerous consequences on health. World Health Organization defines obesity as the “epidemic of the 21st Century”. WHO reports show that 1.9 billion people with 18 years age and older are overweight, and 600 million of them are obese. In the United States, obesity is a serious problem today that results from overconsumption of high-fat food and sugary food with lack of exercise. The Centers for Diseases Control and Prevention reports show that the obesity rates are above 20 percent in all states. Overweight and obesity have become a major public health issue because of their high rates of mortality and morbidity. People who are considered overweight or obese are at increased

In the United States, Obesity is one of the most common physical features for both men and women. Obesity has become one of America’s main health crisis, due to poor eating habits along with lack of exercise leads the cause of obesity. Many people do not participate in sports activities or is capable of working out every day. In result, their body is not able to lose the amount of calories of the harmful food. This debate consist of rather it is lack of exercise, or the most popular subject too much fast food. Majority of obese people are known for eating out a lot and not being aware of the amount times they eat.

Obesity is one of the most rapidly growing health epidemics in the United States and affects more than 60 million people. Despite recent efforts to understand and treat obesity, there has been little success in reversing the rising trend. There is convincing evidence that obesity is directly related to many health risks. As a matter of fact, morbidly obese people are at a high risk for weight related illnesses, such as high blood pressure, type 2 diabetes, high cholesterol, and heart disease. However, research confirms that long-term weight loss success can help to significantly reduce these weight related health risks (Brethauer).

This topic of obesity has been a rising issue for many years. There are many different reasons and predictions as to why the number for this disease is rising in America. Recent epidemiologic studies of diet and health outcomes including obesity have changed the focus to the overall diet quality and dietary pattern instead of single nutrients, such as dietary fat (Hu et al, 2000; Fung et al, 2001a, 2001b). The process starts with the lack of physical exercise and the food that people eat. As Americans, we need to picture more healthier foods to eat, have more physical activity to help food digest easier and faster. According to Campbell “to date, interventions have focused on improving the more amenable determinants of obesity: physical inactivity

Accordingly, a recent analysis by Prentice and Jebb (4) has emphasized the contribution of sedentariness to the increased prevalence of overweight in the United Kingdom. Despite these observations, the contribution of exercise to the prevention and treatment of obesity is still perceived as trivial by many health professionals. The perception of many of them was recently well summarized by Garrow (5) who stated that exercise is a remarkably ineffective means of achieving weight loss in obese people, mainly because their exercise tolerance is so low that the level of physical activity that they can sustain makes a negligible contribution to total energy expenditure. When one looks at the currently available literature, it is difficult to disagree with this statement. Indeed, numerous studies have demonstrated that when exercise is used alone to treat obesity, body weight loss is generally small (6). In addition, the further weight loss generated by adding an exercise program to a reduced-calorie diet is also often small if not insignificant (7). Traditionally, the study of the impact of exercise on body weight control has focused on its energy cost and on the hope that the body energy loss will be equivalent to the cumulative energy cost of exercise sessions. In practical terms, this means for instance that if a physical activity program induces an excess of energy expenditure of 2000 kcal/week, a similar energy deficit should be expected in the active obese

Although many individuals are uncertain about the increasing statistics associated with obesity, more than seventy percent of men and virtually sixty-two percent of women within the United States adult population are overweight or obese (Wilmore, Costill, & Kenney). Obesity refers to the condition of having an excessive amount of body fat. If an individual’s amount of body fat becomes too excessive, he/she is at a much greater risk of developing life-altering diseases such as heart failure, hypertension, type II diabetes, cancer, gallbladder disease, osteoarthritis, etc. (Wilmore, et al., 2008).

Obesity is defined as the excessive build-up of body fat that has major detrimental effects on an individual’s health (Caballero, 2007). The major cause of this excess accumulation of body fat is due to a positive energy balance i.e. when the input of energy into the body system exceeds the output of energy which in turn facilitates in weight gain (Caballero, 2007). Obesity is a major health issue in modern day society, firstly because it affects approximately 300 million people worldwide (Weight Management Centre and secondly, drastic alteration in the body’s fat intake also leads to the increasing prevalence of other major health conditions such as cardiovascular disease, stroke, non-insulin dependent diabetes and hypertension (WMC, 2010).

Obesity, the condition of being severely overweight, is a serious issue in the United States that is gradually beginning to affect more and more citizens. In recent years, the number of Americans suffering from this chronic disease has significantly increased. Researchers have found that nearly one third of the U.S. population is considered overweight and, on average, three hundred thousand individuals die yearly as a result of obesity (Hollands et al. 2). When one participates in little to no physical activity and their diet consists mostly of high fat foods, chances are they will gain weight. If someone becomes obese, they may develop serious health related issues that, in some cases,

Taubes gives many examples about how obesity is not caused by eating too much. But what about not exercising enough? While acknowledging that exercise is important to lower the risks of heart disease and diabetes, he concludes that exercise really does not lead to substantial weight loss. The USDA guidelines have even suggested that up to 90 minutes a day of vigorous exercise

Walking is not simply slow running; competitive race walkers can zip by recreational joggers. The difference between the two is not based on pace. At any speed, walkers have one foot on the ground at all times, but runners are entirely airborne during some part of every stride. As the pace increases, the percentage of each stride that is airborne increases; competitive runners have "hang times" of about 45%.*

A negative energy balance is the goal for weight loss. For weight loss, the BMR, caloric intake, and caloric expenditure are analyzed. It is necessary to determine the kilocalorie adjustment needed for weight loss (see Table 2). For proper energy balance during weight reduction ½ of the reduction should come from a reduction in caloric intake, and ½ should be derived from increased physical activity. A neutral energy balance must be met for weight maintenance.

One topic that has been talked about for many years within Kinesiology is the debate on whether exercise or diet is more important for losing weight and maintaining weight loss. While both or important for a person's individual health, a person's diet is essentially the foundation for a healthy lifestyle and an important factor in losing weight and gaining nutrients that can help the body develop. Many studies and experiments have shown that a healthy diet goes a long way in helping people lose more weight, but more importantly teaches them how to continue to treat their bodies in a healthy manner. Dieting has been shown to have a bigger impact on weight loss than exercise has. For this reason, it can be said that a good diet is more effective for weight loss as compared to exercise alone.
