Obesity is having a body weight that exceeds the normal weight by at least 20%. Thus if you have a body mass index which ranges from 25-29.9 then you are considered as being overweight. In the event that your BMI reads 30 or higher, it shows that you are suffering from obesity.

BMI (Body Mass Index)

This refers to a measurement based on weight and height. It is one of the most appropriate methods of determining a healthy body weight. However, it does not involve the amount of fat the body contains. There are cases where these measurements fail to accurately provide useful information especially when done on a huge muscular man.

The person may have a high BMI but with a low body fat percentage whereas a lean, unfit man with a low BMI could have a higher percentage of body fat. Even though, it is an important method for determining a healthy body weight in an average person and it is done by use of a BMI calculator.

Why obesity attacks people

There are various reasons that lead to people becoming obese and these include:

Consumption of diets with high amounts of calories: Currently, people tend to consume more than what their bodies can utilize. This is a trend that was largely associated with people in developed countries but in the recent times, the problem has spread throughout the world. According to the Obesity Society, by 1980, cases of obesity stood at 14%, but by the year 2000, the figure had escalated to 31%

Sedentary lifestyle: Obesity has largely been associated with being inactive. With the introduction of computers, televisions, remote controls, video games, dishwashers, washing machines and other similar electronic devices, most people have resorted to a very sedentary way of living as compared to the lifestyle their grandparents led.

Unlike in the olden days when people were used to walking long distances to do their shopping, the emergence of big supermarkets and malls and improved transport networks, has led to many people driving to these shopping centres. This contributes to their being less physically active and hence increases the risk of developing obesity.

Lack of enough sleep: By not having sufficient sleep, you will be exposing yourself to obesity; this is according to a research done by the Warwick Medical School at Warwick University. This risk factor is applicable to all, regardless of age. Evidence adduced by Professor Francesco Capuccio and his team from a study carried out on 15,000 adults and 28,000 children indicates that lack of sleep contributes to high levels of obesity in individuals.

Dwelling on diets that affect metabolism (endocrine disruptors): There are proven clues that point at fructose – a sugar molecule – in soft drinks causing interference to the normal metabolic process of the energy lipids. This results to fattening of the liver as well as the metabolic syndrome. The metabolism of fructose is carried out in the liver, which is the most vulnerable organ to changes in metabolism resulting from ingesting fructose.

Lack of exercise and unbalanced diets are among the major causes of obesity in people and besides, they are also responsible for other metabolic complications affecting our modern society. The effect of fructose on the human brain enhances chances of obesity development; this is according to findings by Yale School of Medicine.

Effects of smoking on appetite: The belief that everybody gains weight ones he or she quits smocking is misplaced. Studies by NIH (National Institutes of Health) show that not all who stop smocking gain weight; for those who experience an increase in their body weight, the range is between 6 and 8 pounds. Approximately 10% of individuals who quit this practice register a 30-pound or more weight gain.

Certain types of medication: There are certain types of medications that can lead to obesity; however there is also a variation in the weight gain depending of individuals and types of drugs used. In this case, people who are at a higher risk of being obese should be provided with alternative therapy.

Self-perpetuation of obesity: The longer period one remains overweight, the more difficult it becomes to shed off some extra weight. In this case, it is good to understand that once you become obese, chances are that the condition could develop more. To effectively control this health condition, it is important for patients to intervene during the early stages especially in childhood. This is because if proper care is not taken, obesity becomes a permanent problem for the mere fact that it is self-perpetuating.

Treatment of obesity

Obesity treatment is mostly focused on two main objectives: achieving a healthy weight and maintaining it. The myth that obese individuals must shed considerable amounts of weight before realizing any benefits is false. Losing 5-10% of your body weight is a positive achievement towards a better health. So if your weight is 250 pounds, losing 12-25 pounds is appropriate, at least as a start.

To lose some weight, except diet and exercise, a third idea is to use some natural dietary supplements such as dr oz garcinia cambogia. Some people are reporting that these pills have helped them lose a few extra pounds, in particular as they act not just as fat burner, but also as appetite suppressant.

According to experts, people who are obese and who shed off their weight gradually and steadily (1 to 2 pounds per week) are likely to succeed in their endeavor to keep their body weight down once they arrive at their target as compared to those who tend to lose large amounts of weight within a short time.

The Mayo clinic suggests that physical activity, a good diet plan and your general behavior are keys to a permanent weight loss. In some cases, medication may be necessary while others may require one to undergo surgery.
