Obesity is a condition in which the subject in question has excessive body fat which may pose negative effects on his/her health, and thus reducing the life expectancy of the subject and/or additionally increasing the health problems that the subject may encounter. Obesity is measured using the body mass index (BMI). The BMI is a measure that compares the height and weight of an individual to determine whether s/he is obese or pre-obese. Pre-obese people have a BMI which ranges between 25 to 30 kg/m2 and obese people are people with a BMI above 30 kg/m2. Obesity predisposes individuals to various health conditions, including type II diabetes, osteoarthritis, cardiovascular diseases, obstructive sleep apnea and various types of cancer. Currently, obesity is the leading cause of preventable deaths in the United States of America and many other developed nations round the globe. A number of European and American studies have shown that mortality risks are very low at a BMI of between 20 to 25 kg/m2 in people that do not smoke and at 24–27 kg/m2in people that smoke. The risk increases along with shifts in either direction. The same research has shown that a BMI above 32 doubles the rate of mortality among females aged above 16 years.
Energy imbalances can cause overweight and obesity. An energy imbalance means that your energy IN does not equal your energy OUT. This energy is measured in calories. Energy IN is the amount of calories you get from food and drinks. Energy OUT is the amount of calories that your body uses for things such as breathing, digesting, being physically active, and regulating body temperature.Overweight and obesity develop over time when you take in more calories than you use, or when energy IN is more than your energy OUT. This type of energy imbalance causes your body to store fat.Your body uses certain nutrients such as carbohydrates or sugars, proteins, and fats from the foods you eat to:The amount of energy that your body gets from the food you eat depends on the type of foods you eat, how the food is prepared, and how long it has been since you last ate.The body has three types of fat tissue—white, brown, and beige—that it uses to fuel itself, regulate its temperature in response to cold, and store energy for future use. Learn about the role of each fat type in maintaining energy balance in the body.Some genetic syndromes and endocrine disorders can cause overweight or obesity.Several genetic syndromes are associated with overweight and obesity, including the following.The study of these genetic syndromes has helped researchers understand obesity.Because the endocrine system produces hormones that help maintain energy balances in the body, the following endocrine disorders or " role="link">tumors affecting the endocrine system can cause overweight and obesity.

There is no specific treatment for obesity, but rather a combination of measures that are meant to meant to cut back on the conditions that are implicated in the cause of obesity. However, the two most major approaches are dieting and the engagement in an active exercising life. The reduction in caloric intake is meant to cut back on weight gain, whereas an exercise program is meant to cut back on any already gained weight. Dieting and exercise have been known to be effective in weight reduction, but their effect does not last as long as they are withdrawn. Thus weight maintenance requires a constant maintenance of development of a lasting habit that is developed over time and cultured into the life of an individual. As such there is no medical prescription for any obese cases. There may be drugs that may be recommended for the condition, but these are not as effective and they often lead to complication in the gastrointestinal system. The most effective cited treatment for the condition so far is bariatric surgery which is recommended for severe obesity cases. However, the high cost of this method makes it impossible for access to most people and thus making it less available to many.
The mind over matter principle some how also reaches out to obesity and there is certainly some interactive or causal relation between a person’s emotions and mental state and his weight. The link is however complicated and not easy to explain. For example being in a state of stressful life or occupation may result in obesity. In conducted researches people that reported a single incident of job stress were at a 17% increased risk of being obese, and this rate increased with the reported cases of increased stress.
Excessive caloric intake coupled with a sedentary life is the most common cause of obesity among most obese people. A part from these common causes there a few cases of genetically caused obesity. Genetically obese people are predisposed to the condition due to their genetic make up. Other conditions may also be responsible for obesity, and these may include psychiatric illnesses, medications and endocrine disorders. Despite the genetic pre-disposure, the view that some people gain a lot of weight even with little caloric intake because of a slow metabolism is greatly limited; on average non-obese people have less energy expenditure compared to their fat counterparts because the fat people require more energy to maintain the bigger body mass. Reviews in 2006 identified another 10 potential contributors to the current rise in obesity. The causes include: (1) endocrine disruptors which influence lipid metabolism, (2) less sleep, (3) a high use of medications that increase the likelihood of being obese such as atypical antipsychotics, (4) the increase in close lineage individuals that tend to the condition, (5) pregnancy at a later age, higher BMI natural selection (6) reduced levels of smoking which is responsible for food intake suppression, (7) reduced variability of ambient temperature and (8) genetics. The research on these is inconclusive, but there is an established connection, though not as strong as the earlier stated causes.

To conclude, obesity is a serious health problem. The only way to solve this problem is to make appropriate changes to our lifestyle. People should be encouraged to get physically active and reduce their consumption of fatty foods. The governments and the media can play an importance role in creating awareness about the ill effects of obesity.
The government can discourage people from eating fast foods by spreading awareness about the health problems caused by them and by increasing the taxes on them. When high taxes are imposed on packaged foods, they will become unaffordable to many people. This will reduce their consumption. Employers can also help. They should equip workplaces with gyms so that employees can work out. A quick workout will improve their energy levels and efficiency.
