What are calories?
The goal is always long-term weight loss and maintenance. Because you must push with the legs while you pull with the arms, rowers require coordination. A calorie is a calorie, the advice goes. The conclusion was that mean weight decreased significantly in the intervention group from baseline to year 1 by 2. For the medical journal, see Obesity journal. The prevalence of abdominal obesity is increasing in western populations, possibly due to a combination of low physical activity and high-calorie diets, and also in developing countries, where it is associated with the urbanization of populations. A vegetarian diet focuses on plants for food.
This concept is known as 'lipotoxicity'. Hypercortisolism, such as in Cushing's syndrome , also leads to central obesity. Many prescription drugs, such as dexamethasone and other steroids, can also have side effects resulting in central obesity,  especially in the presence of elevated insulin levels.
The prevalence of abdominal obesity is increasing in western populations, possibly due to a combination of low physical activity and high-calorie diets, and also in developing countries, where it is associated with the urbanization of populations. It is recommended to use both standards. BMI will illustrate the best estimate of your total body fatness, while waist measurement gives an estimate of visceral fat and risk of obesity-related disease.
A study has shown that alcohol consumption is directly associated with waist circumference and with a higher risk of abdominal obesity in men, but not in women. Excluding energy under-reporters slightly attenuated these associations. After controlling for energy under-reporting, it was observed that increasing alcohol consumption significantly increased the risk of exceeding recommended energy intakes in male participants — but not in the small number of female participants 2.
Further study is needed to determine whether a significant relationship between alcohol consumption and abdominal obesity exists among women who consume higher amounts of alcohol. In those with a BMI under 35, intra-abdominal body fat is related to negative health outcomes independent of total body fat. BMI and waist measurements are well recognized ways to characterize obesity. However, waist measurements are not as accurate as BMI measurements.
For this reason, it is recommended to use both methods of measurements. While central obesity can be obvious just by looking at the naked body see the picture , the severity of central obesity is determined by taking waist and hip measurements.
A differential diagnosis includes distinguishing central obesity from ascites and intestinal bloating. In the cohort of 15, people participating in the National Health and Nutrition Examination Survey NHANES III , waist circumference explained obesity-related health risk better than the body mass index or BMI when metabolic syndrome was taken as an outcome measure and this difference was statistically significant.
In other words, excessive waist circumference appears to be more of a risk factor for metabolic syndrome than BMI. The increased amount of fat in this region relates to the higher levels of plasma lipid and lipoproteins as per studies mentioned by Eric Poehlman review. This parameter has been used in the study of metabolic syndrome   and cardiovascular disease. When comparing the body fat of men and women it is seen that men have close to twice the visceral fat as that of pre-menopausal women.
Central obesity is positively associated with coronary heart disease risk in women and men. It has been hypothesized that the sex differences in fat distribution may explain the sex difference in coronary heart disease risk. There are sex-dependent differences in regional fat distribution. In women, estrogen is believed to cause fat to be stored in the buttocks , thighs , and hips. Males are more susceptible to upper-body fat accumulation, most likely in the belly, due to sex hormone differences.
Even with the differences, at any given level of central obesity measured as waist circumference or waist to hip ratio, coronary artery disease rates are identical in men and women. A permanent routine of exercise, eating healthily, and, during periods of being overweight, consuming the same number or fewer calories than used will prevent and help fight obesity.
Adjunctive therapies which may be prescribed by a physician are orlistat or sibutramine , although the latter has been associated with increased cardiovascular events and strokes and has been withdrawn from the market in the United States ,  the UK ,  the EU ,  Australia ,  Canada ,  Hong Kong ,  Thailand ,  Egypt and Mexico.
A study published in the International Journal of Sport Nutrition and Exercise Metabolism ,  suggests that combining cardiovascular aerobic exercise with resistance training is more effective than cardiovascular training alone in getting rid of abdominal fat. An additional benefit to exercising is that it reduces stress and insulin levels, which reduce the presence of cortisol , a hormone that leads to more belly fat deposits.
Self-motivation by understanding the risks associated with abdominal obesity is widely regarded as being far more important than worries about cosmetics. In addition, understanding the health issues linked with abdominal obesity can help in the self-motivation process of losing the abdominal fat.
As mentioned above, abdominal fat is linked with cardiovascular disease, diabetes, and cancer. Specifically it's the deepest layer of belly fat the fat you cannot see or grab that poses health risks, as these "visceral" fat cells produce hormones that can affect health e. The risk increases considering the fact that they are located in the proximity or in between organs in the abdominal cavity. For example, fat next to the liver drains into it, causing a fatty liver , which is a risk factor for insulin resistance, setting the stage for Type 2 diabetes.
In the presence of diabetes mellitus type 2 , the physician might instead prescribe metformin and thiazolidinediones rosiglitazone or pioglitazone as antidiabetic drugs rather than sulfonylurea derivatives. Thiazolidinediones may cause slight weight gain but decrease "pathologic" abdominal fat visceral fat , and therefore may be prescribed for diabetics with central obesity.
Low-fat diets may not be an effective long-term intervention for obesity: The conclusion was that mean weight decreased significantly in the intervention group from baseline to year 1 by 2. This difference from baseline between control and intervention groups diminished over time, but a significant difference in weight was maintained through year 9, the end of the study. There is a common misconception that spot exercise that is, exercising a specific muscle or location of the body most effectively burns fat at the desired location, but this is not the case.
Spot exercise is beneficial for building specific muscles, but it has little effect, if any, on fat in that area of the body, or on the body's distribution of body fat.
The same logic applies to sit-ups and belly fat. Sit-ups , crunches and other abdominal exercises are useful in building the abdominal muscles , but they have little effect, if any, on the adipose tissue located there.
Several colloquial terms used to refer to central obesity, and to people who have it, refer to beer drinking. However, there is little scientific evidence that beer drinkers are more prone to central obesity, despite its being known colloquially as "beer belly", "beer gut", or "beer pot".
One of the few studies conducted on the subject did not find that beer drinkers are more prone to central obesity than nondrinkers or drinkers of wine or spirits. These symptoms can suggest the appearance of central obesity. Deposits of excess fat at the sides of one's waistline are commonly referred to as "love handles". Researchers in Copenhagen examined the relationship between waist circumferences and costs among 31, subjects aged 50—64 years of age with different waist circumferences.
Their study showed that an increase in just an additional centimetre above normal waistline caused a 1. From Wikipedia, the free encyclopedia. Central obesity Synonyms beer belly, beer gut, pot belly, spare tyre, bread box A centrally obese male.
The body mass index is Specialty Endocrinology Abdominal obesity , also known as central obesity , occurs when excessive abdominal fat around the stomach and abdomen has built up to the extent that it is likely to have a negative impact on health.

In the developing world urbanization is playing a role in increasing rate of obesity. Malnutrition in early life is believed to play a role in the rising rates of obesity in the developing world. Consistent with cognitive epidemiological data, numerous studies confirm that obesity is associated with cognitive deficits. The study of the effect of infectious agents on metabolism is still in its early stages.
Gut flora has been shown to differ between lean and obese humans. There is an indication that gut flora in obese and lean individuals can affect the metabolic potential. This apparent alteration of the metabolic potential is believed to confer a greater capacity to harvest energy contributing to obesity.
Whether these differences are the direct cause or the result of obesity has yet to be determined unequivocally. 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. Certain aspects of personality are associated with being obese. There are many possible pathophysiological mechanisms involved in the development and maintenance of obesity. In particular, they and other appetite-related hormones act on the hypothalamus , a region of the brain central to the regulation of food intake and energy expenditure.
There are several circuits within the hypothalamus that contribute to its role in integrating appetite, the melanocortin pathway being the most well understood.
The arcuate nucleus contains two distinct groups of neurons. Both groups of arcuate nucleus neurons are regulated in part by leptin. Thus a deficiency in leptin signaling, either via leptin deficiency or leptin resistance, leads to overfeeding and may account for some genetic and acquired forms of obesity. The World Health Organization WHO predicts that overweight and obesity may soon replace more traditional public health concerns such as undernutrition and infectious diseases as the most significant cause of poor health.
Solutions look at changing the factors that cause excess food energy consumption and inhibit physical activity. Efforts include federally reimbursed meal programs in schools, limiting direct junk food marketing to children,  and decreasing access to sugar-sweetened beverages in schools. Many organizations have published reports pertaining to obesity. This is a comprehensive evidence-based guideline to address the management and prevention of overweight and obesity in adults and children.
Comprehensive approaches are being looked at to address the rising rates of obesity. The Obesity Policy Action OPA framework divides measure into 'upstream' policies, 'midstream' policies, 'downstream' policies. The main treatment for obesity consists of dieting and physical exercise. In the short-term low carbohydrate diets appear better than low fat diets for weight loss. Five medications have evidence for long-term use orlistat , lorcaserin , liraglutide , phentermine—topiramate , and naltrexone—bupropion.
The most effective treatment for obesity is bariatric surgery. In earlier historical periods obesity was rare, and achievable only by a small elite, although already recognised as a problem for health.
But as prosperity increased in the Early Modern period , it affected increasingly larger groups of the population. In the WHO formally recognized obesity as a global epidemic. Once considered a problem only of high-income countries, obesity rates are rising worldwide and affecting both the developed and developing world. Obesity is from the Latin obesitas , which means "stout, fat, or plump". Ancient Greek medicine recognizes obesity as a medical disorder, and records that the Ancient Egyptians saw it in the same way.
It was common among high officials in Europe in the Middle Ages and the Renaissance  as well as in Ancient East Asian civilizations.
With the onset of the Industrial Revolution it was realized that the military and economic might of nations were dependent on both the body size and strength of their soldiers and workers. During the 20th century, as populations reached their genetic potential for height, weight began increasing much more than height, resulting in obesity.
Many cultures throughout history have viewed obesity as the result of a character flaw. The obesus or fat character in Ancient Greek comedy was a glutton and figure of mockery. During Christian times the food was viewed as a gateway to the sins of sloth and lust. People of all ages can face social stigmatization, and may be targeted by bullies or shunned by their peers. The weight that is viewed as an ideal has become lower since the s. In Britain, the weight at which people considered themselves to be overweight was significantly higher in than in Obesity is still seen as a sign of wealth and well-being in many parts of Africa.
This has become particularly common since the HIV epidemic began. Some attribute the Venus figurines to the tendency to emphasize fertility while others feel they represent "fatness" in the people of the time.
This continued through much of Christian European history, with only those of low socioeconomic status being depicted as obese.
These women, however, still maintained the "hourglass" shape with its relationship to fertility. After centuries of obesity being synonymous with wealth and social status, slimness began to be seen as the desirable standard.
In addition to its health impacts, obesity leads to many problems including disadvantages in employment   and increased business costs. These effects are felt by all levels of society from individuals, to corporations, to governments. Obesity prevention programs have been found to reduce the cost of treating obesity-related disease.
However, the longer people live, the more medical costs they incur. Researchers, therefore, conclude that reducing obesity may improve the public's health, but it is unlikely to reduce overall health spending. Obesity can lead to social stigmatization and disadvantages in employment. The most common injuries in this group were due to falls and lifting, thus affecting the lower extremities, wrists or hands, and backs.
Some research shows that obese people are less likely to be hired for a job and are less likely to be promoted. Specific industries, such as the airline, healthcare and food industries, have special concerns. Due to rising rates of obesity, airlines face higher fuel costs and pressures to increase seating width. With the American Medical Association 's classification of obesity as a chronic disease,  it is thought that health insurance companies will more likely pay for obesity treatment, counseling and surgery, and the cost of research and development of fat treatment pills or gene therapy treatments should be more affordable if insurers help to subsidize their cost.
In , The European Court of Justice ruled that morbid obesity is a disability. The Court said that if an employee's obesity prevents him from "full and effective participation of that person in professional life on an equal basis with other workers", then it shall be considered a disability and that firing someone on such grounds is discriminatory. The principal goal of the fat acceptance movement is to decrease discrimination against people who are overweight and obese.
A number of organizations exist that promote the acceptance of obesity. It has more of a global orientation and describes its mission as promoting size acceptance and helping to end weight-based discrimination. The American legal system, however, has decided that the potential public health costs exceed the benefits of extending this anti-discrimination law to cover obesity.
In the New York Times published an article on the Global Energy Balance Network , a nonprofit founded in that advocated for people to focus on increasing exercise rather than reducing calorie intake to avoid obesity and to be healthy. Hand and Steven N. The healthy BMI range varies with the age and sex of the child. As with obesity in adults, many factors contribute to the rising rates of childhood obesity. Changing diet and decreasing physical activity are believed to be the two most important causes for the recent increase in the incidence of child obesity.
