Obesity is a medical condition in which excess body fat accumulates to the point that it can have a negative effect on health, leading to health problems. It can also be defined as an abnormal or excessive accumulation of fat that can present a health risk. According to WHO, 2013, body mass index (BMI) is a measurement that can be obtained by dividing a person's weight (in kilograms) by the square of the person's height (in meters). “A person is considered obese when their BMI is equal to or greater than 30 kg/m2. A person with a BMI equal to or greater than 25 kg/m2 is considered overweight” (WHO, 2013). Obesity is most commonly caused by a combination of excessive dietary energy intake, lack of physical activity and genetic predisposition. Obesity is a major risk factor for a number of chronic diseases, including cardiovascular disease, diabetes and cancer. For our information, unconscious overweight and obesity represent the fifth risk of death globally. At least 2.8 million adults died each year due to obesity. Furthermore, there are statistics attributable to the obese where approximately 44% are linked to diabetes, 23% are linked to ischemic heart disease and between 7% and 41% are linked to some cancers. The research was conducted by some of the World Health Organizations (WHO) estimating the year 2008; more than 1.4 billion are adults aged 20 or older and were overweight. Of these overweight adults, more than 200 million men and nearly 300 million women were obese. Overall, more than 10% of the world's adult population was obese (WHO, 2013). Besides that, based on BMI (body mass index), in 1996 there were almost more than 25 Malaysians and only 5% obese, which increased to 14% in 2006 and 15% in 2012. . to participate in this campaign. Apart from this, the government and NGOs must help improve facilities in every village of the state. So everyone has the opportunity to practice sports or meditation with the facilities provided. Simply put, people suffering from obesity are increasing year after year without realizing it. Many people consider obesity a simple problem, but in reality obesity becomes the fifth risk of global death. While the causes of obesity are many, there are also many ways to prevent it. Therefore, we should be wise to prevent obesity because it can lead to many problems, especially health problems. We must remember that prevention is much better than cure. Hopefully after this Malaysians can be more careful about this issue and follow a good eating habit. We Malaysians must be healthy so that we can lead our country in achieving development.
