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.
Brown fat tissue is located in the upper back area of human infants. This fat type releases stored energy as heat energy when a baby is cold. It also can make inflammatory substances. Brown fat can be seen in children and adults.

Over two-thirds of American adults are overweight or obese (National Health and Nutrition Examination Survey, 2004), with many estimates even higher (ACSM 2010). People must be more than 20 percent heavier than the recommended bodyweight for their height to be considered obese, yet bodyweight based on height chart assessments alone does not identify how much extra fat a person is carrying. Another method that does not identify body fat but rather uses bodyweight relative to height (kg/m2) is the body mass index (BMI). The National Institutes of Health (2007) use BMI values between 25 and 29.9 and those greater than 30 for classifying people who are overweight and obese, respectively. When skinfold measurements, or the more precise method of underwater weighing, are used to determine body-fat percentage, values that exceed the normal range by at least 5 percent are considered obese. In older populations, ACSM (2010) has suggested that satisfactory body-fat values for men and women age 50 to 59 are between 10 and 22 percent and 20 and 32 percent, respectively. Average body-fat values reported by the Cooper Institute for men age 60 to 69 and 70 to 79 are 22.6 and 23.1 percent, respectively, and those for women are 27.9 and 28.6 percent, respectively (ACSM 2010). Although girth measurements may also be used with older adults, they may not be as helpful because there are no well-established values for persons over 56 years of age. Regardless of the method used for assessing body composition, the lifestyles of many Americans clearly contribute to their weighing too much.
“Baby boomers who are not obese and younger generations are going to have to foot the trillions of dollars in health care costs for the millions of unhealthy boomers,” Slome explains.  “Healthy boomers approaching retirement have very little time left to develop a plan so they are not left depending on already strapped government programs or forced to deplete whatever retirement savings they managed to squirrel away.”

Though it’s difficult to say why some people develop cancer while others don’t, research shows that certain risk factors increase a person’s odds of developing cancer. These risk factors include growing older, family history of cancer, diet, alcohol and tobacco use, and exposure to sunlight, ionizing radiation, certain chemicals, and some viruses and bacteria.
Future trials need to address specific exercise training modalities, calcium, Vitamin D and protein supplementation, and/or prescribing anti-resorptive therapy (e.g. in patients with low BMD to start with) during active weight loss. Trials specifically designed to investigate the complex interplay between exercise, caloric restriction, weight loss, diet composition, hormones, growth factors, and inflammatory markers are also needed. Finally, trials need to have adequate sample size with appropriate controls, and long follow-up periods are needed to determine how best to achieve sustained lifestyle change associated with optimal health outcomes in frail, obese older adults. With the 65+ age group representing the fastest growing segment of the population, and with a high prevalence of obesity, these studies should become a priority for public health research.
Additionally, drugs have side effects, some quite serious, such as insomnia, nervousness, depression, high blood pressure and rapid heartbeat. Fen-phen had to be withdrawn by the Food and Drug Administration because it caused dangerous complications, including heart problems and pulmonary hypertension. However, there are real alternative diet aids that offer real benefits without any risks.
Literally. The more flexible you are, the more you will enjoy any physical activity you do and the less chance you’ll have of hurting yourself, says Rami Aboumahadi, a nationally certified personal trainer. And at 60+, a less active lifestyle and an increase in aches and pains can make your flexibility plummet. Consider taking a yoga class or even simply adding a few stretches to your day, particularly after you’ve taken a walk or warmed up your muscles in some other way. Get started with these 6 feel-good yoga stretches.
Classes for the obese or seniors should be taught by an experienced yoga teacher adept at adapting the traditional poses for those students who are physically challenged. Many schools, such as the American Yoga Association, have developed programs that teach yoga exercises that can be done in chairs or even in bed. Yoga practitioners say even small movements can have beneficial effects, especially when coupled with deep breathing and instruction in relaxation and meditation.
Just as genetics plays a role in obesity, so does the environment. The environment includes the world around us; it influences access to healthy food and safe places to walk. What we eat, our level of physical activity, and our lifestyle behaviors are influenced by our environment. Our environment can prevent us from eating healthy foods and/or getting adequate exercise in a number of ways. Examples include the trend toward ‘eating out’ rather than preparing food in the home; high-fat, high-calorie foods in our workplace vending machines; neighborhoods that often lack sidewalks; and a deficit of readily accessible recreation areas.
It’s hard to change habits. You have to be ready. Make sure this is the right time for you. Are you ready to make a plan and stay on it? Do you have the support of your family and friends? Do you know what your first steps will be? Becoming healthier and staying that way is a lifelong effort.
An association between viruses and obesity has been found in humans and several different animal species. The amount that these associations may have contributed to the rising rate of obesity is yet to be determined.[147]
Endometrial cancer: Obese and overweight women are two to about four times as likely as normal-weight women to develop endometrial cancer (cancer of the lining of the uterus), and extremely obese women are about seven times as likely to develop the more common of the two main types of this cancer (7). The risk of endometrial cancer increases with increasing weight gain in adulthood, particularly among women who have never used menopausal hormone therapy (8).

Family lifestyle. Obesity tends to run in families. If one or both of your parents are obese, your risk of being obese is increased. That’s not just because of genetics. Family members tend to share similar eating and activity habits.
Among a cohort of 250 residents of a Dutch nursing home, after adjusting for age and sex, a significant relationship was seen between body weight and mobility (p < 0.0001), appetite (p < 0.001), thirst (p < 0.01) and consumption of extra food (p < 0.0001).10 In multivariate analysis, only difficulties in bringing food to the mouth and chewing were significantly associated with weight loss. Similarly, in a cross-sectional study involving 109 patients (99% male) admitted to a geriatric rehabilitation unit in the United States, oral problems were the strongest predictor of substantial, involuntary weight loss in the year before admission.11 The interaction between diet and gut bacteria can predispose us to obesity from the day we are born, as can the mode by which we enter the world. Studies have shown that both formula-fed babies and infants delivered by cesarean section have a higher risk for obesity and diabetes than those who are breast-fed or delivered vaginally. Working together, Rob Knight of the University of Colorado Boulder and Maria Gloria Dominguez-Bello of N.Y.U. have found that as newborns traverse the birth canal, they swallow bacteria that will later help them digest milk. C-section babies skip this bacterial baptism. Babies raised on formula a different disadvantage: they do not get substances in breast milk that nurture beneficial bacteria and limit colonization by harmful ones. According to a recent Canadian study, babies drinking formula have bacteria in their gut that are not seen in breast-fed babies until solid foods are introduced. Their presence before the gut and immune system are mature, says Dominguez-Bello, may be one reason these babies are more susceptible to allergies, asthma, eczema and celiac disease, as well as obesity. ^ Jump up to: a b Afshin A (12 June 2017).

Dr. Ryan Masters and Dr. Bruce Link at Columbia University’s Mailman School of Public Health, in collaboration with Dr. Daniel Powers at the University of Texas, published the results of the study online this week in the American Journal of Epidemiology. Unintentional weight loss is defined as an involuntary decline in body mass, usually occurring over a relatively short period of time. The condition is quite common among elderly adults, particularly those over 70 years of age. Seniors who experience this form of weight loss lose some of their ability to function independently, see a reduction in quality of life and have an increased risk of mortality. Unintentional weight loss can result from a variety of conditions, with physical, mental, emotional and social factors playing potential roles. Up to 25 percent of cases among the elderly have no identifiable cause. While these countries continue to deal with the problems of infectious diseases and undernutrition, they are also experiencing a rapid upsurge in noncommunicable disease risk factors such as obesity and overweight, particularly in urban settings. Their results showed that people born between 1966 and 1985 became obese at a much faster rate than people born in previous generations. Researchers found that 20% of people born in 1966-1985 were obese by 20-29 years of age. That prevalence of obesity was not reached until ages 50-59 for people born in 1926-1935 and until ages 40-49 for people born a decade later. 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] She says the decrease in smoking shows that it's possible to change health behaviors, noting that doctors, public health professionals and policymakers used a variety of strategies simultaneously to reduce smoking.

    Improved medical care also could be contributing to rising disability, Martin suggested. People whose disabilities began early in life are now living longer. “It could be seen as good news: improved survival for people with Down syndrome or spinal cord injuries who might have not reached middle age in the past,” she said.
    A stroke happens when the flow of blood to a part of your brain stops, causing brain cells to die. The most common type of stroke, called ischemic stroke, occurs when a blood clot blocks an artery that carries blood to the brain. Another type of stroke, called hemorrhagic stroke, happens when a blood vessel in the brain bursts.
    Although a biological link between obesity and depression has not yet been definitively identified, possible mechanisms include activation of inflammation, changes in the hypothalamic-pituitary-adrenal axis, insulin resistance, and social or cultural factors.
