The table Risks of Obesity-Associated Diseases by BMI and Waist Circumference provides you with an idea of whether your BMI combined with your waist circumference increases your risk for developing obesity-associated diseases or conditions.
“In older, obese people, it may be more important to improve physical function and quality of life, rather than to reverse or treat risk factors for cardiovascular disease,” says Villareal, now chief of geriatrics at the New Mexico Veterans Affairs Health Care System and professor of medicine at the University of New Mexico School of Medicine, both in Albuquerque. “Combining exercise and weight loss isn’t designed so much to extend their life expectancy as it is to improve their quality of life during their remaining years and to help seniors avoid being admitted to a nursing home.”
When we grow older, we tend to lose our muscle mass and it gets replaced with fat. Our BMI (Body Mass Index) may not change, but in reality, our fat-stores increase, as does the chance of being affected by obesity and its related diseases. BMI can also be inaccurate in seniors for another common reason. As we grow old, we often get shorter. This is due to osteoporosis and spinal vertebral issues that take away inches in older age. Since BMI is a measure calculated from height and weight, a change in height will change BMI as well. In fact, if a senior weighs the same, and his or her height is now less, then the BMI will be falsely higher. This could classify the senior as “overweight”, while in reality, that is not the case. Scientists and physicians still debate about a better measure for weight classification, but for now, BMI is the accepted one and physicians need to use it, while understanding its limitations. 
By placing wholesome eating directly at odds with healthier processed foods, the Pollanites threaten to derail the reformation of fast food just as it’s starting to gain traction. At McDonald’s, “Chef Dan”—that is, Dan Coudreaut, the executive chef and director of culinary innovation—told me of the dilemma the movement has caused him as he has tried to make the menu healthier. “Some want us to have healthier food, but others want us to have minimally processed ingredients, which can mean more fat,” he explained. “It’s becoming a balancing act for us.” That the chef with arguably the most influence in the world over the diet of the obese would even consider adding fat to his menu to placate wholesome foodies is a pretty good sign that something has gone terribly wrong with our approach to the obesity crisis.

Excess food portions. Americans are surrounded by huge food portions in restaurants, fast food outlets, gas stations, movie theaters, supermarkets, and even home. Eating large portions means too much energy IN. Over time, this will cause weight gain if it isn’t balanced with physical activity.
BMI is a measurement used to indicate obesity and morbid obesity in adults. BMI is calculated by dividing a person’s weight in kilograms by his or her height in meters squared. An adult with a BMI of 30 or greater is considered to have obesity. To calculate your BMI, please click here.
Most practitioners and researchers define unintentional weight loss as a 5% to 10% decrease in body weight over a period of 1 to 12 months.3-6 A clinically useful benchmark is 5% over a 6-month period. In 25% of cases, etiology is idiopathic and unknown.7 Identified etiologies generally include:

“We want to address the problem head-on,” he said. “Obesity creates incredible public health problems. We want to make BMI another vital sign, like blood pressure. Even if you’re just coming in because you have a cold, your BMI will be measured and tracked.

During the Renaissance some of the upper class began flaunting their large size, as can be seen in portraits of Henry VIII of England and Alessandro dal Borro.[15] Rubens (1577–1640) regularly depicted full-bodied women in his pictures, from which derives the term Rubenesque. These women, however, still maintained the “hourglass” shape with its relationship to fertility.[199] During the 19th century, views on obesity changed in the Western world. After centuries of obesity being synonymous with wealth and social status, slimness began to be seen as the desirable standard.[15]
How did the most educated and wealthiest generation of Americans to date allow its collective health to fall by the wayside? The American lifestyle has largely shifted from active to sedentary and from community-oriented to socially isolating. Adults experience more stress in their hectic daily lives, which breeds depression and health problems, such as hypertension and high blood pressure. The net result of those factors is poor health and chronic ailments.
Obesity happens over time when you eat more calories than you use. The balance between calories-in and calories-out differs for each person. Factors that might affect your weight include your genetic makeup, overeating, eating high-fat foods, and not being physically active.
The researchers who conducted the earlier CDC study suggested that public health efforts and aggressive treatments aimed at preventing chronic diseases had greatly reduced the obesityobesity-related death risk.
Obesity is a leading preventable cause of death worldwide, with increasing rates in adults and children.[1][13] In 2015, 600 million adults (12%) and 100 million children were obese.[7] Obesity is more common in women than men.[1] Authorities view it as one of the most serious public health problems of the 21st century.[14] Obesity is stigmatized in much of the modern world (particularly in the Western world), though it was seen as a symbol of wealth and fertility at other times in history and still is in some parts of the world.[2][15] In 2013, the American Medical Association classified obesity as a disease.[16][17]

Drug therapy or bariatric surgery may be suggested for older obese patients. However, all benefits and risks should be taken into consideration before opting for surgery. Surprisingly enough, the outcomes, complications, and mortality rates associated with bariatric surgery have been shown to be acceptable for adults age 65 and older.
Yet these hurdles can be waved away, if one only has the proper mind-set. Bittman argued two years ago in The Times that there’s no excuse for anyone, food-desert-bound or not, to eat fast food rather than wholesome food, because even if it’s not perfectly fresh and locally grown, lower-end wholesome food—when purchased judiciously at the supermarket and cooked at home—can be cheaper than fast food. Sure, there’s the matter of all the time, effort, schedule coordination, and ability it takes to shop, cook, serve, and clean up. But anyone who whines about that extra work, Bittman chided, just doesn’t want to give up their excessive TV watching. (An “important benefit of paying more for better-quality food is that you’re apt to eat less of it,” Pollan helpfully noted in his 2008 book, In Defense of Food.) It’s remarkable how easy it is to remake the disadvantaged in one’s own image.
In addition to its health impacts, obesity leads to many problems including disadvantages in employment[200][201] and increased business costs. These effects are felt by all levels of society from individuals, to corporations, to governments.
Like many other medical conditions, obesity is the result of an interplay between genetic and environmental factors.[118] Polymorphisms in various genes controlling appetite and metabolism predispose to obesity when sufficient food energy is present. As of 2006, more than 41 of these sites on the human genome have been linked to the development of obesity when a favorable environment is present.[119] People with two copies of the FTO gene (fat mass and obesity associated gene) have been found on average to weigh 3–4 kg more and have a 1.67-fold greater risk of obesity compared with those without the risk allele.[120] The differences in BMI between people that are due to genetics varies depending on the population examined from 6% to 85%.[121]
Cancer: Obesity can increase your risk for certaincancers such as colon, endometrial, breast, and gallbladder. Obese and overweight women have two to four times the risk of developing endometrial cancer, regardless of their menopausal status.
Maintaining your ideal body weight is a balancing act between food consumption and calories needed by the body for energy. You are what you eat. The kinds and of food you eat affect your ability to maintain your ideal weight and to lose weight.

Many people suffer from health issues due to their weight. Some people who need to lose weight for their health don’t recognize it, while others who don’t need to lose weight want to get thinner for cosmetic reasons.
In Sacramento and across the nation, the number of baby boomers who are overweight or obese continues to climb, and as a group, they have hit middle age much heavier than the previous generation. Almost three of four people ages 49 to 67 – the baby boom generation – are overweight or obese in the four-county Sacramento region, according to a new survey from the UCLA Center of Health Policy Research.
In fact, more than half of boomers polled say they regularly do mental exercises such as crossword puzzles. Some also take fish oil, a type of fatty acid that some studies suggest might help prevent mental decline.
Such steps are enormously promising, says Jamy Ard, an epidemiology and preventive-medicine researcher at Wake Forest Baptist Medical Center in Winston-Salem, North Carolina, and a co-director of the Weight Management Center there. “Processed food is a key part of our environment, and it needs to be part of the equation,” he explains. “If you can reduce fat and calories by only a small amount in a Big Mac, it still won’t be a health food, but it wouldn’t be as bad, and that could have a huge impact on us.” Ard, who has been working for more than a decade with the obese poor, has little patience with the wholesome-food movement’s call to eliminate fast food in favor of farm-fresh goods. “It’s really naive,” he says. “Fast food became popular because it’s tasty and convenient and cheap. It makes a lot more sense to look for small, beneficial changes in that food than it does to hold out for big changes in what people eat that have no realistic chance of happening.”
Nearly 40 percent of U.S. adults have obesity, and ​​more than 18 percent of children and teens also have obesity. This condition disproportionately affects people from certain racial and ethnic groups and those who are socio-economically disadvantaged.
Several areas of research are exploring mechanisms that link obesity and cancer (29, 46). One research area involves understanding the role of the microbes that live in the human gastrointestinal tract (collectively called the gut microbiota, or microbiome) in both type 2 diabetes and obesity. Both conditions are associated with dysbiosis, an imbalance in the collection of these microbes. For example, the gut microbiomes of obese people are different from, and less diverse than, those of non-obese people. Imbalances in the gut microbiota are associated with inflammation, altered metabolism, and genotoxicity, which may in turn be related to cancer. Experiments in mice show that the microbiome may influence the efficacy of some types of cancer treatment, particular immunotherapy (47, 48). Researchers are beginning to think about ways to change the microbiota of cancer patients to improve their outcomes.
