Excessive accumulation of body fat, but not so great as to be classified as obesity.
There is no universally agreed definition, but most people are considered overweight if they are 15-20 per cent greater than their ideal weight as determined by standard tables. These tables usually take into account age, height, build, and sex. Excess weight can put great strains on the body, particularly the joints in the legs and back. Although there is a connection between overweight and obesity, not all overweight people are obese. Muscle has a higher density than fat, so highly muscular people may be overweight but not obese. Conversely, a sedentary person with normal body weight could have a small muscle mass, large fat stores, and be suffering from obesity. See also body mass index.
Definition: heavier than average
Antonyms: skinny, thin, underweight
A body weight that exceeds a normal or standard weight for a person of a particular sex, height, and frame size. Although there is no universally agreed system, a person is generally regarded as overweight if he or she is 15-20% heavier than the appropriate weight as determined by standard tables such as those prepared by the Metropolitan Life Insurance Company are often used. These are based on population averages. Those who are overweight are assumed to be a greater health risk because excess weight is often in the form of fatty tissue, which increases the risk of cardiovascular diseases. Excess weight can also overload the joints. However, the standard tables are based on population averages, which do not necessarily apply to athletes. According to the tables, many American Footballers are overweight, yet they are much fitter and leaner than people of a comparable age and body build in the general population. See also obesity.
1. A situation where a portfolio holds an excess amount of a particular security when compared to the security's weight in the underlying benchmark portfolio. Actively managed portfolios will make a security overweight when doing so will allow the portfolio to achieve excess returns.
2. An analyst's opinion regarding the future performance of a security. Overweight will usually signify that the security is expected to outperform either its industry, sector or, even, the market altogether.
Investopedia Says:
1. Securities will usually be overweight when a portfolio manager believes that the security will outperform other securities in the portfolio. An example of overweighting a security would be when a portfolio normally holds a security at a weight of 15%, and the security's weight is raised to 25% in an attempt to increase the returns of the portfolio.
2. An example of an analyst's rating of overweight would be: The stock's return is expected to be above the average return of the overall industry over the next eight to 12 months. Specific analyst definitions vary regarding the time frame used and the benchmark the security is compared against.

Overweight is generally defined as having more body fat than is optimally healthy. Being overweight is a common condition, especially where food supplies are plentiful and lifestyles are sedentary.
Excess weight has reached epidemic proportions globally, with more than 1 billion adults being either overweight or obese.[1] Increases have been observed across all age groups.
A healthy body requires a minimum amount of fat for the proper functioning of the hormonal, reproductive, and immune systems, as thermal insulation, as shock absorption for sensitive areas, and as energy for future use. But the accumulation of too much storage fat can impair movement and flexibility, and can alter the appearance of the body.

The degree to which a person is overweight is generally described by body mass index (BMI). Overweight is defined as a BMI of 25 or more, thus it includes pre-obesity defined as a BMI between 25 and 30 and obesity as defined by a BMI of 30 or more.[2][3] Pre obese and overweight however are often used interchangeably thus giving overweight a common definition of a BMI of between 25 -30. There are however several other common ways to measure the amount of adiposity or fat present in an individual's body.
The most common method for discussing this subject and the one used primarily by researchers and advisory institutions is BMI. Definitions of what is considered to be overweight vary by ethnicity. The current definition proposed by the US National Institutes of Health (NIH) and the World Health Organization (WHO) designates whites, Hispanics and blacks with a BMI of 25 or more as overweight. For Asians, overweight is a BMI between 23 and 29.9 and obesity for all groups is a BMI of 30 or more.
BMI, however, does not account extremes of muscle mass, some rare genetic factors, the very young, and a few other individual variations. Thus it is possible for an individuals with a BMI of less than 25 to have excess body fat, while others may have a BMI that is significantly higher without falling into this category.[6] Some of the above methods for determining body fat are more accurate than BMI but come with added complexity.
If an individual is overweight and has excess body fat it could, but won't always, create or lead to health risks. Reports are surfacing, however, that being mildly overweight to slightly obese – BMI being between 24 and 31.9 – may be actually beneficial and that people with BMI between 24 and 31.9 could actually live longer than normal weight or underweight persons.[7][8]
While the negative health outcomes associated with obesity are accepted within the medical community, the health implications of the overweight category are more controversial. The generally accepted view is that being overweight causes similar health problems to obesity, but to a lesser degree. Adams et al. estimated that the risk of death increases by 20 to 40 percent among overweight people,[9] and the Framingham heart study found that being overweight at age 40 reduced life expectancy by three years.[10]
Flegal et al., however, found that the mortality rate for individuals who are classified as overweight (BMI 25 to 30) may actually be lower than for those with an "ideal" weight (BMI 18.5 to 25).[11][12]
Being overweight has been identified as a cause of cancer, and is projected to overtake smoking as the primary cause of cancer in developed countries as cases of cancer linked to smoking dwindle.[13]
Psychological well-being is also at risk in the overweight individual due to social discrimination. However, children under the age of eight are normally not affected.[14]
Being overweight does not increase mortality in older people.[15]
As much as 64% of the United States adult population is considered either overweight or obese, and this percentage has increased over the last four decades.[16]
Being overweight is generally caused by the intake of more calories (by eating) than are expended by the body (by exercise and everyday living). Factors which may contribute to this imbalance include:
People who have insulin dependant diabetes and chronically overdose insulin may gain weight, while people who already are overweight may develop insulin tolerance, and in the long run type II diabetes.
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 physical exercise. For those who are obese rather than overweight, more intensive therapies such as anti-obesity drugs and/or bariatric surgery are sometimes used.
Studies suggest that reducing calorie intake by itself (dieting) may have short-term effects but does not lead to long-term weight loss, and can often result in gaining back all of the lost weight and more in the longer term. For this reason, it is generally recommended that weight-loss diets not be attempted on their own but instead in combination with increased exercise and long-term planning and weight management.
The health benefits of weight loss are also somewhat unclear. While it is generally accepted that for significantly obese patients, losing weight can reduce health risks and improve quality of life, there is some evidence to suggest that for merely overweight patients, the health effects of attempting to lose weight may actually be more detrimental than simply remaining overweight.[17] Moreover, for all individuals, repeatedly losing weight and then gaining it back ("weight cycling" or "yo-yo dieting"), is believed to do more harm than good and can be the cause of significant additional health problems. This is caused by the loss of more muscle than fat.
