The balance between calorie intake and energy expenditure determines a person’s weight. If a person eats more calories than he or she burns (metabolizes), the person gains weight (the body will store the excess energy as fat). If a person eats fewer calories than he or she metabolizes, he or she will lose weight. Therefore the most common causes of obesity are overeating and physical inactivity. Ultimately, body weight is the result of genetics, metabolism, environment, behavior, and culture.
Reexamination of the impact of obesity on health in older individuals disclosed two potential benefits of weight excess: decreased osteoporosis and better survival of obese subjects with certain health hazards, known as the “obesity paradox.” Obesity, linked to increased bone mineral density, is thus far uncontested, as is the fact that this also translates into a lower rate of hip fractures in elderly obese subjects (10). The latter may reflect not only greater bone resilience, but also improved cushioning by adipose tissue during falls. An important emerging exception to this general protective effect of obesity on bone is the recent finding that although men and women with the metabolic syndrome do indeed enjoy better total hip and femoral neck bone mineral density in a cross-sectional analysis, these associations do not translate to improved clinical outcome. In fact, incident clinical fractures were 2.6 times more likely to occur in subjects with the metabolic syndrome compared with participants without the metabolic syndrome after an average follow-up of 2 years (11).
Despite these seemingly high percentages, it appears that many Americans underestimate their weight problems. According to the National Center for Health Statistics (NCHS), 64% of U.S. adults are overweight or obese.

Heart-healthy eating. Learn about which foods and nutrients are part of a healthy eating pattern. It’s important to eat the right amount of calories to maintain a healthy weight. If you need to lose weight, try to reduce your total daily calories gradually. Use the Body Weight Planner to find out your daily calorie needs and to set goals. Visit healthy recipes and plan for success. Talk with your doctor before beginning any diet or eating plan. Visit Chose My Plate or 2015-2020 Dietary Guidelines for Americans for more information.
Phenylpropanolamine (PPA) is often found in appetite suppressants as well as over-the-counter cough and cold remedies. The FDA has recommended that products containing PPA be removed from the market. Studies have suggested that this product is associated with an increased risk of hemorrhagic (bleeding) stroke in women.
Our model is designed to provide comfort, practical fitness, small group training and healthy, everyday meals. The goal is to provide a lifestyle you can replicate and maintain after you return home – without spending exorbitant amounts of money.
The NIDDK also plays a leading role in the NIH Obesity Research Task Force, which organizes scientific meetings and seminars, engages in strategic planning for NIH obesity research, and promotes and coordinates collaborative research efforts across the NIH.
Esophageal adenocarcinoma: People who are overweight or obese are about twice as likely as normal-weight people to develop a type of esophageal cancer called esophageal adenocarcinoma, and people who are extremely obese are more than four times as likely (9).
The calorie needs calculator is designed to allow you to enter your ideal weight and determine the number of daily calories you should eat to reach that goal. Remember to consult a physician before beginning any diet or exercise plan – particularly if you have a chronic condition.
Other methods of estimating body fat and body fat distribution include measurements of skinfold thickness and waist circumference, calculation of waist-to-hip circumference ratios, and techniques such as ultrasound, computed tomography, and magnetic resonance imaging (MRI).

Moreno also suggests that seniors be especially careful to achieve a diet that is nutritionally balanced but provides plenty of protein. For most adults, this means including a source of lean protein at every meal. Sources of protein might include eggs, egg whites, fish, chicken, turkey, and lean cuts of meat.

Obesity clearly exacerbates the age-related decline in physical function and causes frailty in older individuals. Frailty in older obese individuals may be related to the insulin resistance and inflammation that often accompany obesity (36). This is reflected by self-reported impairment in activities of daily living in the older obese individual, limitations in mobility and decreased physical performance (as detailed in the former segment), increased risk for functional decline, and a higher rate of nursing home admissions (35,37–39). Of particular significance in establishing a cause-and-effect relationship between obesity and frailty is the recent report that weight loss and exercise can ameliorate frailty in older obese adults (40).
This first step is an obvious one that you’ve probably heard or tried more times than you’d like to remember. But it’s a necessary first step that, if achieved, will be the most rewarding and healthy weight loss option.
Muscle mass decreases from about 45 percent of your total body weight in your youth to about 27 percent by the time you reach age 70. And the drop in hormones that accompanies menopause also precipitates a decrease in muscle mass, triggering even more weight gain for women. Your body fat, meanwhile, can double, even if your weight remains the same.
After the pounds have melted off, you cannot go back to the old diet as the weight will come back again. Continue monitoring your dog’s weight on a bi-weekly basis. You may need to make some adjustments after the ideal weight has been reached. Consult with your vet for the maintenance diet for your senior pet, and be sure to weigh the food you give per day to make tweaking amounts easier in case of future weight gain.
potentially abused by patients. While most of the immediate side-effects of these drugs are harmless, the long-term effects of these drugs, in many cases, are unknown. Two drugs, dexfenfluramine hydrochloride (Redux) and fenfluramine (Pondimin) as well as a combination fenfluramine-phentermine (Fen/Phen) drug, were taken off the market when they were shown to cause potentially fatal heart defects. In November 1997, the United States Food and Drug Administration (FDA) approved a new weight-loss drug, sibutramine (Meridia). Available only with a doctor’s prescription, Meridia can significantly elevate blood pressure and cause dry mouth, headache, constipation, and insomnia. This medication should not be used by patients with a history of congestive heart failure, heart disease, stroke, or uncontrolled high blood pressure.
When a person’s heart beats, it creates a force to pump blood, pushing it against arterial walls. That force is called blood pressure. Low blood pressure helps the body function normally, but sustained high blood pressure can damage it in many ways. For one, it can lead to hardening of the arteries, which decreases the flow of blood and oxygen to the heart. When the heart isn’t receiving enough blood or oxygen, the risk for chest pain (angina), heart failure, or heart attack increases. High blood pressure is also a risk factor for kidney disease, aneurysms, and bursting or bleeding of blood vessels in the eyes, which lead to vision changes or blindness. Your chances of having high blood pressure increase if you’re overweight or obese.
