A follow-up study was recently released in the American Journal of Public Health, in which Masters and his colleagues found that obesity accounts for 18 percent of deaths in people ages 40 to 85. This estimate is more than four times higher than researchers previously thought. Due to environmental factors—more sedentary lifestyle, processed foods—the study says each generation is obese for a longer period than the former, a factor not considered in previous estimates.

The AP’s poll was conducted from June 3-12 by Knowledge Networks of Menlo Park, Calif., and involved online interviews with 1,416 adults, including 1,078 baby boomers born between 1946 and 1964. Knowledge Networks used traditional telephone and mail sampling methods to randomly recruit respondents. People selected who had no Internet access were given it free.
If you plan to lose more than 15 to 20 pounds, have any health problems, or take medication on a regular basis, you should be evaluated by your doctor before beginning your weight-loss program. A doctor can assess your general health and any medical conditions that might be affected by dieting and weight loss. Also, a physician should be able to advise you on the need for weight loss, the appropriateness of the weight-loss program, and a sensible goal of weight loss for you. If you plan to use a very low-calorie diet (a special liquid formula diet that replaces all food intake for one to four months), you should do so under the close supervision of a health-care professional.

Overweight and obesity are major risk factors for a number of chronic diseases, including diabetes, cardiovascular diseases and cancer and while it was once an issue only in high income countries, overweight and obesity has now dramatically risen in low- and middle-income countries.Such countries are now facing a “double burden” of disease, for while they continue to deal with the problems of infectious disease and under-nutrition, they are also experiencing a rapid upsurge in chronic disease risk factors such as obesity and overweight, particularly in urban settings.
Surgery to correct obesity (known as bariatric surgery) is a solution for some obese people who cannot lose weight on their own or have severe obesity-related medical problems. Generally, surgery is recommended only for morbidly obese people (body mass index 40 or greater). This means men who are at least 100 pounds overweight and women who are at least 80 pounds overweight.
A recent study indicated that central obesity, assessed by several anthropometric indicators, is associated with the presence of erectile dysfunction in men >60 years, but not in younger men (42). Although age appeared to be the major determinant of erectile dysfunction in NHANES, obesity had an independent contributory effect, increasing the odds ratio for impotence by 1.6 (43). In a cross-sectional analysis of men >50 years of age in the U.S. Health Professionals’ Study, obesity independent of other confounding factors increased the risk of erectile dysfunction by 30% (44).
Overweight and obesity are linked to more deaths worldwide than underweight. Globally there are more people who are obese than underweight – this occurs in every region except parts of sub-Saharan Africa and Asia.
Physician-supervised weight-loss programs provide treatment in a clinical setting with a licensed healthcare professional, such as a medical doctor, nurse, registered dietitian and/or psychologist. These programs typically offer services such as nutrition education, pharmacotherapy, physical activity and behavioral therapy.
The good news that losing a small amount of weight can reduce your chances of developing heart disease or a stroke. Losing 5%-10% of your weight is proven to lower your chance of developing heart disease.

Another important number to know is your waist size in inches. Having too much fat around your waist may increase health risks even more than having fat in other parts of your body. Women with a waist size of more than 35 inches and men with a waist size of more than 40 inches may have higher chances of developing diseases related to obesity.

Reducing calories and practicing healthier eating habits are vital to overcoming obesity. Although you may lose weight quickly at first, slow and steady weight loss over the long term is considered the safest way to lose weight and the best way to keep it off permanently.
Increasing or initiating a physical activity program is an important aspect in managing obesity. Today’s society has developed a very sedentary lifestyle and routine physical activity can greatly impact your health.
Obesity is a topic of significant importance at medical schools and other programs for healthcare professionals. For example, Creighton University’s online Master of Public Health degree addresses the obesity epidemic, its consequences and treatment. The Creighton program provides students with the techniques and tools to have an effect on public health. The program also offers service-oriented concentrations, such as Public Health Services Administration, which provides leadership and management skills to promote public health and service the public.
The most likely culprits for weight gain and obesity are food intake and sedentary lifestyles, though genetic factors can also play a role. Sweetened beverages (sodas and juices) and potato chips are two of the biggest contributors, along with our alarmingly-large portion sizes. Ever-increasing access to fast food and processed foods also play a major role.Sedentary lifestyles are also a major cause of obesity and weight gain. And while our society has become more sedentary as a whole, seniors – already less active than other age groups –feel the impact on their waistlines even more.

In 2000, smoking cessation, diet and exercise could have prevented around 35 percent of the deaths in the United States [source: CDC]. Baby boomers get a gold star for their nonsmoking efforts but fail when it comes to the latter two health initiatives. Being overweight and obese drastically increases a person’s chance of developing chronic diseases, such as heart disease and diabetes. It puts extra wear and tear on the body’s muscles and joints and reduces mobility.

Psychological factors. For some people, emotions influence eating habits. Many people eat excessively in response to emotions such as boredom, sadness, stress, or anger. While most overweight people have no more psychological disturbances than normal weight people, about 30% of the people who seek treatment for serious weight problems have difficulties with binge eating.

Because they are energy-intense foods, fat and sugar and other problem carbs trip the pleasure and reward meters placed in our brains by evolution over the millions of years during which starvation was an ever-present threat. We’re born enjoying the stimulating sensations these ingredients provide, and exposure strengthens the associations, ensuring that we come to crave them and, all too often, eat more of them than we should. Processed food is not an essential part of this story: recent examinations of ancient human remains in Egypt, Peru, and elsewhere have repeatedly revealed hardened arteries, suggesting that pre-industrial diets, at least of the affluent, may not have been the epitome of healthy eating that the Pollanites make them out to be. People who want to lose weight and keep it off are almost always advised by those who run successful long-term weight-loss programs to transition to a diet high in lean protein, complex carbs such as whole grains and legumes, and the sort of fiber vegetables are loaded with. Because these ingredients provide us with the calories we need without the big, fast bursts of energy, they can be satiating without pushing the primitive reward buttons that nudge us to eat too much.
In the second paper, all CVD risk factors significantly improved in the diet and exercise group (Villareal 2006b). Specific mechanisms were not proposed, but the discussion focused on medical care costs related to metabolic coronary heart disease (CHD) risk factors that were ameliorated by the intervention (Table 1). In the third paper (Villareal 2008), bone turnover was measured by type 1 collagen C-terminal telopeptide (CTX), osteocalcin, and bone-specific alkaline phosphatase. There was a marked increase in serum CTX (~100-fold) and osteocalcin (~60-fold) concentrations in response to weight loss indicating that bone resorption and formation, respectively, were stimulated. Moreover, the increases in both CTX and osteocalcin concentrations correlated with decreases in hip bone mineral density (BMD), suggesting that weight-loss induced bone loss was due to increased bone turnover, with greater stimulation of bone resorption than bone formation. However, the clinical significance of the decrease in BMD was not clear as all participants had high baseline BMD Z-scores, and none had evidence of osteoporosis following weight loss. The investigators argued that BMD was not lost in the spine, which implies that the exercises were more effective in preserving BMD at this site. Exact mechanisms for loss of BMD with weight loss are not currently elucidated, but it was suggested that weight loss decreases the mechanical stress on the hip, without negatively impacting the spine or wrist. Weight loss was also associated with a 25% reduction in serum leptin that was highly correlated with decreased hip BMD. No such relationship was found between decreasing estradiol and changes in BMD. Leptin was discussed in the context of its inhibiting action on the expression of receptor activator of nuclear factor κB (NF-κB) ligand levels (Burguera 2001) and osteoblast differentiation (Cornish 2002). Levels of insulin-like growth factor 1 (IGF-1), cortisol, and parathyroid hormone (PTH) did not change in response to weight loss, which suggests that these bone-active hormones were not involved with the loss of BMD in the hip. Vitamin D supplementation during the trial did not reach optimal serum concentrations and whether higher dose Vitamin D supplementation could have slowed bone loss, was raised by the investigators. It was also noted that bone quality was not measured and could have been positively impacted by the exercise training intervention.
