As for Anne Roberson, she says the extra weight she has long carried around on her petite frame has begun taking a toll on her joints, her sleep and her mood. On a recent morning, Roberson listened politely to Dr. Mylene Middleton Rucker, her longtime physician, during her first Medicare weight loss counseling session. Rucker suggested she eat more vegetables and less meat and encouraged her to join a local exercise class.
Kelly et al. (2011) recruited 28 sedentary, obese adults who were weight stable for the previous six months. The group was randomly allocated to exercise plus either a low-glycemic index (LGI) or high-glycemic index (HGI) diet. Participants engaged in five exercise sessions per week for 60 minutes at 85% maximum heart rate. All food was provided and balanced for macronutrients and both groups lost similar amounts of weight over the six month intervention. Weight, FM, FFM, truncal fat, fasting plasma glucose and insulin decreased in both groups, but did not differ between groups. Glycemic response reduced only in the LGI group. Plasma and mononuclear cells (MNC)-derived TNFα reduced in the LGI group, but increased in the HGI group. Secretion of IL-6 from MNC and plasma IL-6 and monocyte chemotactic protein-1 (MCP-1) was reduced in the LGI group. Change in MNC-derived TNFα and plasma MCP-1 correlated with decreased glycemic response. It was concluded that a LGI diet plus exercise decreased inflammatory markers, whereas a HGI diet attenuated improvements in glycemia and inflammation that usually occur with exercise. One proposed mechanism was the production of nicotinamide adenine dinucleotide phosphate (NADPH), which results in reactive oxygen species that activates the NFkB pathway, and increases TNF-α (Mohanty 2000; Evans 2002; Ghanim 2004). Hypertrophied adipocytes in obesity are partially responsible for the secretion of IL-6, and are thus regulated by not only weight loss, but also hyperglycemia and physical activity. The decrease of MCP-1 in the LGI group associated with changes in plasma glucose was attributed to reduced stimulus to recruit MNC into adipose tissue, seen as improved glucose tolerance. This implies an improvement in adipose tissue function, and the investigators concluded that eating a LGI diet in combination with aerobic exercise can reverse the effects of obesity on proinflammatory cytokines, which appears independent of weight loss.

(Review). 10 (7): 431–42. doi:10.1038/nrg2594. PMID 19506576. However, it is also clear that genetics greatly influences this situation, giving individuals in the same ‘obesogenic’ environment significantly different risks of becoming obese.
Psychological conditions that contribute to weight loss must be addressed promptly, as they can result in rapid loss of body mass if left untreated. Counselling, therapy and perhaps medication may be required to mitigate the effects of the mental condition.
Obesity results from the accumulation of excess fat on the body. Obesity is considered a chronic (long-term) disease, like high blood pressure or diabetes. It has many serious long-term consequences for your health, and it is a leading cause of preventable deaths in the United States (with tobacco use and high blood pressure). Obesity is defined as having a body mass index (BMI) of greater than 30. The BMI is a measure of your weight relative to your height.
If you think you may be obese, and especially if you’re concerned about weight-related health problems, see your doctor or health care provider. You and your provider can evaluate your health risks and discuss your weight-loss options.
Skin calipers: This method measures the skinfold thickness of the layer of fat just under the skin in several parts of the body with calipers (a metal tool similar to forceps); the results are then used to calculate the percentage of body fat.
Chitosan is a special fiber found in the shell of shellfish like crabs and lobsters. Fiber and its use as a weight loss aid have been the topic of considerable study in the last several decades. Increasing dietary fiber intake naturally decreases fat intake, because fiber-rich foods are relatively low in fat and cholesterol. In addition, increasing fiber usually decreases LDL (bad cholesterol) and increases HDL (good cholesterol), reducing the risk of heart disease.

Doctors sometimes prescribe fluoxetine (Prozac), an antidepressant that can increase weight loss by about 10%. Weight loss may be temporary and side effects of this medication include diarrhea, fatigue, insomnia, nausea, and thirst. Weight-loss drugs currently being developed or tested include ones that can prevent fat absorption or digestion; reduce the desire for food and prompt the body to burn calories more quickly; and regulate the activity of substances that control eating habits and stimulate overeating.

The next class (category) of drugs changes the metabolism of fat. Orlistat (Xenical, alli) is the only drug of this category that is U.S. FDA approved. This is a class of anti-obesity drugs called lipase inhibitors, or fat blockers. Fat from food can only be absorbed into the body after being broken up (a process called digestion) by digestive enzymes called lipases in the intestines. By inhibiting the action of lipase enzymes, orlistat prevents the intestinal absorption of fat by 30%. Drugs in this class do not affect brain chemistry. Theoretically, orlistat also should have minimal or no systemic side effects (side effects in other parts of the body) because the major locale of action is inside the gut lumen and very little of the drug is absorbed.
Often, you’ll be able to find senior-focused classes offered at local swimming pools, but if not, even just starting off by walking around the pool and doing some mild stretches can make a huge differences.
In patients over 65, the increase in chronic diseases associated with aging reduces physical activity and exercise capacity, making it more difficult for elderly persons to lose weight. The large number of older people with obesity and associated serious health risks make understanding the causes of obesity crucial. Obese older adults are more likely to be severely disabled and require the assistance of another person than those who are not obese (Center on an Aging Society, 2003). Older adults who are obese are more likely to suffer from persistent and chronic symptoms of illness, and to report symptoms of depression. In addition to having difficulty with activities of daily living, older obese adults are more likely to not be able to walk very far, go shopping, or participate in other activities that enrich lives (Center on an Aging Society).
“We think it’s the perfect storm of several factors,” says Dr. Scott Kahan, an obesity medicine specialist at George Washington University. Kahan says obese patients and doctors aren’t aware of the benefit, and doctors who want to intervene are often reluctant to do so.
Appetite suppressing medications are popular because we need help in controlling food intake. Relying on drugs does not solve the problem. Often these over-the-counter and prescription medications work for a few weeks, becoming ineffective as the body learns to ignore them-a process known as tolerance.
It’s time for some straight talk: You weigh more than you did ten years ago, or even five years ago. The extra pounds didn’t arrive all at once but accumulated gradually before you even realized they were climbing on board. Now you’re looking at some serious extra poundage. But that’s to be expected as you get older, right? Wrong.

Well, it depends. Weight-loss that is not planned is not uncommon. The elderly are often sicker and need longer periods of time to recover from illness than younger adults. This often results in weight-loss. This type of weight-loss is not healthy. A significant portion of weight lost during illness is muscle loss.
The most effective treatment for obesity is bariatric surgery. The types of procedures include laparoscopic adjustable gastric banding, Roux-en-Y gastric bypass, vertical-sleeve gastrectomy, and biliopancreatic diversion. Surgery for severe obesity is associated with long-term weight loss, improvement in obesity related conditions, and decreased overall mortality. One study found a weight loss of between 14% and 25% (depending on the type of procedure performed) at 10 years, and a 29% reduction in all cause mortality when compared to standard weight loss measures. Complications occur in about 17% of cases and reoperation is needed in 7% of cases. Due to its cost and risks, researchers are searching for other effective yet less invasive treatments including devices that occupy space in the stomach.
Depression may be one of the most common effects of obesity. Many obese people suffer emotional distress. Because of the emphasis on physical appearance in our culture, which equates slimness with beauty, obese people may feel unattractive. They also are subjected to prejudice, ridicule, and discrimination, which may make them feel ashamed or rejected.

350 pounds is the maximum weight a standard hospital bed can handle, and there is no national census to increase the weight or offer additional beds for heavier patients. Because of the expensive costs of the equipment, staffing issues and increased health problems, assisted living communities and nursing homes rarely accept more than a few markedly obese patients.

This is almost double what it was in 1960, which means that more of us are getting heavier. An alarming trend is that weight problems begin earlier in life than ever before. Millions of kids are overweight and research shows that obese children are very likely to become obese adults.
Obesity is not just a cosmetic problem. It’s a health hazard. Someone who is 40% overweight is twice as likely to die prematurely as is an average-weight person. This is because obesity has been linked to several serious medical conditions, including:
