The rise in income and population growth have increased the demand for food and induced changes in food habits, food purchasing and consumption patterns in Malaysia.With this transition, one of the plausible causes of weight gain and obesity is the frequent consumption of outside food which is synonymous with bigger portion size. Therefore, the aim of this paper is to develop a system dynamics model to analyse the effect of reducing food portion size on weight and obesity prevention.This study combines the different strands of knowledge comprise of nutrition, physical activity and body metabolism.These elements are synthesized into a system dynamics model called SIMULObese.Findings from this study suggested that changes in eating behavior should not emphasize only on limiting the food portion size consumption.The efforts should also consider other eating events such as controlling the meal frequency and limiting intake of high-calorie food in developing guidelines to prevent obesity.
