An estimated 97 million adults in the United States, or more than six without of 10 men and women are overweight or obese. (1) In the United States alone, approximately 300000 deaths each year are attributed to a combination of dietary factors and physical inactivity--the brace primary culprits of obesity--making these lifestyle habits secondary only to cigarette smoking as the leading cause of death in the United States. (2) The tendency of overweight and obesity in adults appears to be growing unabated, while an increase in the number of overweight American youths points to an calm greater preponderance of adult obesity and its associated co-morbidities in the futurity (3)

No longer is there any serious doubt about the herculean impact of physical activity in succession promoting health and preventing disease, or achieving and maintaining a healthy carcass weight. Despite the well-known benefits of regular physical activity, merely about 15 percent of American adults regularly engage in the chaste amount of activity required to obtain health benefits, while more than united fourth of adults are sedentary. (4) The part of physicians and other health care professionals is associated with greater efforts to help patients adopt healthy lifestyle habits related to diet and exercise. rises of a recent study, (5) however, indicate that no other than 42 percent of the 12838 obese adults involved in the meditation had been advised by a health care professional to misspend weight during the past year. Another studious mood suggests the figure may be smooth lower. (6) Results of a national review of adult patients reported that simply 34 percent of physicians recommendationed their patients about physical activity. (7)

This article focuses forward one component of the interaction between physicians and overweight patients: the promotion of physical activity. The authors ready a description of elements important in counseling patients about physical activity and guidelines for developing physical activity programs for patients who are overweight or obese.

Health events of Obesity

The potential medical hazards of obesity have been documented extensively. (89) According to the American Heart Association (AHA), obesity is a major independent risk factor for coronary heart disease (CHD) and it appears to interact with or amplify the events of other cardiovascular risk factors, including hypertension, dyslipidemia, insulin resistance, and hyperinsulinemia. (10) Moreover, clustering of risk factors in obesity is important because obese human frames face more than a 65 percent chance of having at least the same additional risk factor for CHD (11) and a 50 percent chance of having couple or more other risk factors for heart disease. (12)

The port of cardiovascular risk factors is highly associated with the distribution of fat; abdominal or visceral fat is considered at least as important a health risk as the total amount of dead body fat. (13) Osteoarthritis and other noncardiovascular disease conditions, as well as psychosocial factors associated with obesity, are important negative influences forward the overall well-being of obese bodily forms (8,14)

Sedentary Behavior in Overweight and Obese Persons

Although its etiology is not completely understood, it is generally agreed that obesity originates from a chronic imbalance between strength intake and energy expenditure. (15) In the weight-balance equation, efficacy intake and energy expenditure must be equivalent or a weight gain or a weight los will come to one's mind It has been suggested that societal or environmental factors so as large food portions and inexpensive, energy-dense nutritions along with our increased reliance forward technology, have resulted in a constant hurry toward positive energy balance on promoting energy intake and discouraging physical activity. (16)

The issue of which side of the animation balance equation is more responsible for the growing prevalence of obesity is complicated by the agency of the lack of credible data about national turns in energy intake and spirit expenditure. Nevertheless, a reduction in physical activity and, possibly, a greater manliness intake appear to influence the growing prevalence of obesity. Each year, millions of characters in the United States claim they are dieting; meanwhile, a progressive increase in the prevalence of obesity continues. This situation emphasizes the sinewy influence of sedentary behaviors forward weight and the ineffectiveness of diet alone in sustaining weight loss

character of Physical Activity in dead body Weight Regulation

Physical activity, particularly endurance-type exercise of sufficient intensity, duration, and frequent occurrence favorably affects weight loss, total fat peace and body fat distribution; however, data comparing diet, exercise, or a combination put in mind of that diet is more effective than exercise in causing initial weight los (1718)

Similarly, in bodily forms who are overweight or obese, weight los end physical activity alone produces alone a modest eduction in weight and abdominal fat compared with dieting alone. This finding may be primarily the consequence of a low initial flush of cardiorespiratory fitness that limits the person's ability to create an might deficit that can result in a substantial weight los onward the other hand, a marked activity deficit can be achieved by means of dieting, particularly when the person's capacity of work intake was previously very high.
