Obesity is defined as a condition in which an individual has an excess of body fat and it is accumulated to the extent that it can lead to numerous health problems and decreases the quality and length of life. Overall, the contributing factor to obesity varies. Lack of physical activity and increased sedentary behaviour has been identified as the causes of weight gain and various health implications including obesity. Rapid development in industrialization and urbanization has brought Malaysia to be the next millennium country in the world, and this causes changes in the country's socioeconomic, especially the lifestyles of Malaysians. In conjunction with this, the aim of this paper is to simulate the changes in physical activities and to highlight its implication on body weight and prevalence of overweight and obesity in a Malaysian adult population. This study combines different strands of knowledge consisting of nutrition, physical activity and body metabolism, and these elements have been synthesised into a system dynamics model called SIMULObese. The development of this model has considered the interrelations between those various strands in one multifaceted human weight regulation system. Findings from this study revealed that Malaysian adults perform less physical activity and this has resulted in weight gain and increase in prevalence of overweight and obesity. Therefore, findings from this study bring the important message to various parties such as practitioners, researchers, educators and publics about the importance of focusing on combinations of intensity, frequency and duration of moderate-vigorous activity for adult obesity control in Malaysia.
