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.
Obesity can influence various aspects of reproduction, from sexual activity to conception. Among women, the association between obesity and infertility, primarily ovulatory infertility, is represented by a classic U-shaped curve. In the Nurses’ Health Study, infertility was lowest in women with BMIs between 20 and 24, and increased with lower and higher BMIs. (20) This study suggests that 25 percent of ovulatory infertility in the United States may be attributable to obesity. During pregnancy, obesity increases the risk of early and late miscarriage, gestational diabetes, preeclampsia, and complications during labor and delivery. (21) It also slightly increases the chances of bearing a child with congenital anomalies. (22) One small randomized trial suggests that modest weight loss improves fertility in obese women. (23)
Increased body mass has a negative impact on weight-bearing joints, and knee osteoarthritis is particularly common in obese men (58%) and women (68%) by the age of ≥65 years (41). The physical limitation caused by this condition is widely appreciated, but less attention is paid to the inevitable impact on pain and chronic overconsumption of analgesics that often underlie the development of drug-resistant hypertension and incipient nephropathy.
The key to successful long-term weight loss is to focus less on “dieting,” which tends to be a short-term fix, and more on lifestyle changes, primarily healthy eating, and regular exercise. Your goal should be to make health, not appearance, your priority, meaning your weight loss lifestyle changes must include both diet and exercise.
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.
More than 30% of adults (50% of baby boomers) have this condition. The bad news is metabolic syndrome can kill you before you ever develop diabetes. Because it changes your cholesterol profile, increases inflammation, and raises your blood pressure levels in ways that are similar to those of diabetes, it can cause a heart attack or cyproheptadine has been studied in patients with cancer and cachexia,38 routine use in older adults with unintentional weight loss has not been studied. Dronabinol (Marinol) and human growth hormone have been studied in small, limited trials with mixed results for short-term, small weight gains. Dronabinol has been associated with significant adverse effects, particularly central nervous system toxicity. Human growth hormone has been associated with increased mortality.17
Obesity and Cardiovascular Death. In a meta-analysis of 26 observational studies that included 390,000 men and women, several racial and ethnic groups, and samples from the U.S. and other countries, obesity was significantly associated with death from CAD and cardiovascular disease. Women with BMIs of 30 or higher had a 62 percent greater risk of dying early from CAD and also had a 53 percent higher risk of dying early from any type of cardiovascular disease, compared with women who had BMIs in the normal range (18.5 to 24.9). Men with BMIs of 30 or higher had similarly elevated risks. (11)
Gordon’s team then repeated the experiment with one small twist: after giving the baby mice microbes from their respective twins, they moved the animals into a shared cage. This time both groups remained lean. Studies showed that the mice carrying microbes from the obese human had picked up some of their lean roommates’ gut bacteria—especially varieties of Bacteroidetes—probably by consuming their feces, a typical, if unappealing, mouse behavior. To further prove the point, the researchers transferred 54 varieties of bacteria from some lean mice to those with the obese-type community of germs and found that the animals that had been destined to become obese developed a healthy weight instead. Transferring just 39 strains did not do the trick. “Taken together, these experiments provide pretty compelling proof that there is a cause-and-effect relationship and that it was possible to prevent the development of obesity,” Gordon says.
As societies become increasingly reliant on energy-dense, big-portions, and fast-food meals, the association between fast-food consumption and obesity becomes more concerning. In the United States consumption of fast-food meals tripled and food energy intake from these meals quadrupled between 1977 and 1995.

Enlisting support. Get your family and friends on board with your weight-loss goals. Surround yourself with people who will support you and help you, not sabotage your efforts. Make sure they understand how important weight loss is to your health. You might also want to join a weight-loss support group.
There is controversy in regard to carbohydrates and weight loss. When carbohydrates are restricted, people often experience rapid initial weight loss within the first two weeks. This weight loss is due mainly to fluid loss. When carbohydrates are added back to the diet, weight gain often occurs, simply due to a regain of the fluid.
Losing weight is difficult, and interventions that work in younger adults cannot be assumed to translate to older populations with co-morbidities, low muscle mass and frailty (Villareal 2004). The appropriate treatment approach for obesity remains highly contentious due to the lack of evidenced-based data demonstrating that long-term weight loss is net beneficial or harmful in this age group. There is evidence that successful weight loss is possible in adults 65 years and older (Villareal 2006a; Villareal 2006b; Villareal 2008; Frimel 2008; Lambert 2008; Shah 2009; Villareal 2011a; Armamento-Villareal 2012; Shah 2011; Kelly 2011). However, weight-loss trials have reported losses of lean body mass and bone mineral density, in addition to fat mass (Villareal 2006a; Villareal 2006b; Villareal 2008; Frimel 2008; Lambert 2008; Shah 2009; Villareal 2011a; Armamento-Villareal 2012; Shah 2011; Kelly 2011; Bales 2008). These negative outcomes discourage many geriatricians from advising weight loss to their obese older patients (Heiat 2001; Rossner 2001; Sorensen 2003; Villareal 2005; Zamboni 2005; Rolland 2006; Morley 2010), despite improvements in body composition, physical function, metabolic and cardiovascular parameters that accompany weight loss (Forsythe 2008; Anandacoomarasamy 2009; Cheung 2012; Erteck 2012). Given these positive functional and metabolic outcomes, it is somewhat surprising that advising weight loss in obese older adults is still shunned in the medical community (Houston 2009; Sommers 2011). Compounding the confusion surrounding risks versus benefits from intentional weight loss is the lack of human studies to elucidate the mechanisms associated with the loss of muscle and bone. Also lacking are trials with adequate follow-up to assess the behaviors associated with long-term maintenance of weight loss and health outcomes related to sustained weight loss.
Take up a physical hobby like dancing, yoga, or water aerobics instead of — or in addition to — something sedentary like bingo or bridge. Keeping up the physical activity will help you keep the mobility you have and may even increase flexibility and range of movement. And you may even make some new friends.

“Everyone’s mother and brother has been telling them to eat more fruit and vegetables forever, and the numbers are only getting worse. We’re not going to solve this problem by telling people to eat unprocessed food.”
Fewer studies have examined possible associations between weight loss and cancer risk. Some of these have found decreased risks of breast, endometrial, colon, and prostate cancers among people who have lost weight. However, most of these studies were not able to evaluate whether the weight loss was intentional or unintentional (and possibly related to underlying health problems).
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.
Obesity is associated with a modest risk for developing rheumatoid arthritis (RA). Given the rapidly increasing prevalence of obesity, this has had a significant impact on RA incidence and may account for much of the recent increase in the incidence of RA.A
Obesity is a disease that affects more than one-third of the U.S. adult population (approximately 78.6 million Americans). The number of Americans with obesity has steadily increased since 1960, a trend that has slowed in recent years but shows no sign of reversing. Today, 69 percent of U.S. adults are categorized as being affected by obesity or having excess weight.
