Obesity - Causative factors. When energy intake exceeds energy expenditure, fat cells (and to a lesser extent muscle and liver cells) throughout the body take in the energy and store it as fat. In its simplest conception, therefore, obesity is only made possible when the lifetime energy intake exceeds lifetime energy expenditure by more than it does for individuals of "normal weight." In all individuals, the excess energy utilized to generate fat reserves is minute relative to the total number of calories ...

Obesity - Culture and obesity. In several human cultures, obesity is associated with attractiveness, strength, and fertility. Some of the earliest known cultural artifacts, known as Venuses, are pocket-sized statuettes representing an obese female figure. Although their cultural significance is unrecorded, their widespread use throughout pre-historic Mediterranean and European cultures suggests a central role for the obese female form in magical rituals, and suggests cult ...

Obesity is a condition where the natural energy reserve, stored in the fatty tissue of humans and mammals is increased to the point where it may impair health. Obesity in wild animals is relatively rare, but it is common in domestic animals like pigs and household pets who may be overfed and underexercised. In humans it is generally considered to be a leading cause of health problems. Excessive body weight has been shown to predispose to various forms of disease, particularly cardiovascular disease. Interventions, such as weigh ...

Underweight refers to a human who is considered to be under a healthy weight. The definition is usually made with reference to the body mass index (BMI). Most consider individuals under 18.5 to be underweight - although some authorities use a higher value of 20. It is important to note that the BMI is a statistical estimate and some indivduals classified as underweight may be perfectly healthy. Underweight - Problems. Underweight individuals generally have poor physical stamina and a weak immune system - le ...

Acanthosis nigricans - Causes. This occurs due to insulin spillover (from excessive production due to obesity or insulin insensitivity) into the skin which results in abnormal growth being observed. The most common cause would be insulin resistance, usually from type 2 diabetes mellitus.< ...

While there are several known health issues associated with obesity, the health implications of being simply overweight (but not obese) are substantially less well known. A significant amount of medical research on obesity in the past has led to the general conclusion, maintained by many in the medical community, that being even slightly overweight may be detrimental to one's health in a variety of ways, and should be avoided if possible. However, some recent studies have suggested that mortality rates for individuals who are classified as o ...

A large number of people undergo some form of treatment to attempt to reduce their weight, usually either in an attempt to improve their health, to improve their lifestyle, or for cosmetic reasons. The generally recommended treatment for being overweight is a modified or controlled diet in conjunction with increased exercise. For those who are significantly obese, more severe methods such as drugs or surgery may be recommended, but should generally only be pursued on a doctor's recommendation after a thorough examination of the patient and analysis of previously attempted remedies (for more information on this, ...

A 2000 study by the UCSD School of Medicine and the Veterans Affairs Healthcare System in San Diego, used functional magnetic resonance imaging (fMRI) technology to monitor activity in the brains of sleep-deprived subjects performing simple verbal learning tasks. The study showed that regions of the brain’s prefrontal cortex (PFC) displayed more activity in sleepier subjects. Depending on the task at hand, in some cases the brain attempts to compensate for the adverse effects caused by lack of sleep. The temporal lobe, which is a brain reg ...

Since sleep deprivation is a fact of modern combat, the U.S. army, through DARPA, has a "Preventing Sleep Deprivation Program", which has the goal to prevent the harmful effects of sleep deprivation and provide methods for recovery of function with particular emphasis on cognitive and psychomotor impairments. Their efforts include new pharmaceuticals that enhance neural transmission, nutraceuticals that promote neurogenesis, cognitive trainin ...

Underweight individuals generally have poor physical stamina and a weak immune system - leaving them open to infection. They are also at higher risk from heart disease, blood vessel disease, and osteoporosis. In women, being underweight can result in amenorrhoea (absence of periods) and possible complications during pregnancy. ...

The degree to which a person is overweight is generally described using an indication of the amount of excess body fat present. There are several common ways to measure the amount of fat present in an individual's body: Simple Weighing: The weight of the individual is measured and compared to an estimated ideal weight. This is the easiest and most common method, but by far the least accurate, as it only measures one quantity (weight) and often does not take into account many factors such as height, body type, and relative ...

Being overweight is generally caused by the intake of more calories (by eating) than are expended by the body (by exercise). Factors which may contribute to this imbalance include: Limited exercise and sedentary lifestyle Genetic predisposition A high glycemic diet (i.e. a diet that consists of meals that give high postprandial blood sugar) Weight cycling, caused by repeated attempts to lose weight by dieting Underlying illness (e.g. hypothyroidism) An eating disorder (such as binge eating disorder) Stressful mentality Insufficient sleeping Psychotropic medicati ...

Central obesity is common in polycystic ovary syndrome (PCOS) and Syndrome X, and it is associated with a statistically higher risk of heart disease, hypertension, insulin resistance and diabetes mellitus type 2. Central obesity can also be a feature of lipodystrophies, a group of diseases which is either inherited, or due to secondary causes (often protease inhibitors, a group of medications against AIDS). ...

Some anti-obesity drugs have severe and often life-threatening side effects. (See, for example, Fen-phen.) These side effects are often associated with their mechanism of action. In general, stimulants carry a risk of high blood pressure, faster heart rate, palpitations, closed-angle glaucoma, drug addiction, restlessness, agitation, and insomnia. Orlistat is unlikely to cause these serious side effects since it is not a stimulant. Therefore, orlistat may be a better choice for obese patients with conditions that might be aggravated b ...
