Not only do most people regain weight lost on a fast, they tend to add a few extra pounds because a slower metabolism makes it easier to gain weight. Worse, the weight that is regained is likely to be all fat -- lost muscle has to be added back at the gym. Side effects of fasting include dizziness , headaches , low blood sugar , muscle aches, weakness , and fatigue.

Prolonged fasting can lead to anemia , a weakened immune system, liver and kidney problems, and irregular heartbeat. Fasting can also result in vitamin and mineral deficiencies, muscle breakdown, and diarrhea. When you drink laxative concoctions during a fast, there is an increased risk of fluid imbalance and dehydration.

The risks get more complicated and severe the longer you stay on a fast, or if you repeatedly go on fasts. It sounds logical that fasting could cleanse your body of harmful substances that could cause a host of ailments like obesity , fatigue , and headaches. But there is no scientific evidence that you need to fast to "cleanse" your body or remove toxins. Your body - specifically, the kidneys , liver , lungs , colon , and skin -- is perfectly capable of removing toxins itself.

Nutrition experts agree that fasting is a potentially dangerous, and not particularly effective, way to lose weight.

Central obesity can be a feature of lipodystrophies , a group of diseases that is either inherited , or due to secondary causes often protease inhibitors , a group of medications against AIDS.

Central obesity is a symptom of Cushing's syndrome [13] and is also common in patients with polycystic ovary syndrome PCOS. Central obesity is associated with glucose intolerance and dyslipidemia. Once dyslipidemia becomes a severe problem, an individual's abdominal cavity would generate elevated free fatty acid flux to the liver. The effect of abdominal adiposity occurs not just in those who are obese, but also affects people who are non-obese and it also contributes to insulin sensitivity.

Recent validation has concluded that total and regional body volume estimates correlate positively and significantly with biomarkers of cardiovascular risk and BVI calculations correlate significantly with all biomarkers of cardio-vascular risk.

There are numerous theories as to the exact cause and mechanism in Type 2 Diabetes. Central obesity is known to predispose individuals for insulin resistance. Abdominal fat is especially active hormonally, secreting a group of hormones called adipokines that may possibly impair glucose tolerance.

But adiponectin which is found in lower concentration in obese and diabetic individuals has shown to be beneficial and protective in Type 2 diabetes mellitus. Developing asthma due to abdominal obesity is also a main concern. As a result of breathing at low lung volume, the muscles are tighter and the airway is narrower. It is commonly seen that people who are obese breathe quickly and often, while inhaling small volumes of air.

Based on studies, it is evident that obesity has a strong association with vascular and metabolic disease which could potentially be linked to Alzheimer's disease. Recent studies have also shown an association between mid-life obesity and dementia, but the relationship between later life obesity and dementia is less clear.

Based on logistic regression analyses, it was found that obesity was associated with an almost fold increase risk of Alzheimer's disease. The currently prevalent belief is that the immediate cause of obesity is net energy imbalance—the organism consumes more usable calories than it expends, wastes, or discards through elimination. Some studies indicate that visceral adiposity, together with lipid dysregulation and decreased insulin sensitivity , [39] is related to the excessive consumption of fructose.

Quality protein uptake is defined as the ratio of essential amino acids to daily dietary protein. Visceral fat cells will release their metabolic by-products in the portal circulation, where the blood leads straight to the liver.

Thus, the excess of triglycerides and fatty acids created by the visceral fat cells will go into the liver and accumulate there. In the liver, most of it will be stored as fat. 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, [50] 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 [67] [68] 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 , [83] the UK , [84] the EU , [85] Australia , [86] Canada , [87] Hong Kong , [88] Thailand , [89] Egypt and Mexico.

A study published in the International Journal of Sport Nutrition and Exercise Metabolism , [90] 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.

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.
