Introduction: Currently obesity is the most global health issue that faced by developed and developing countries. A Hundred millions of people around the world have been obese, and many more who could potentially experience. Obesity occurs because of imbalance between energy intake and expenditure generated from the habits and physiology mechanism. At least, these variables are known to occur due to environmental factors, genetic factors, as well as interaction both of them. Changing in behavior and
physiological condition leading to energy imbalance and implies to body weight regulation.
Methods: Recent theories have been developed to elucidate the interaction of genetic, environmental, and body weight regulation. For example, the theory of thrifty genes, set point, and the settling point has become debate concerning this topic.
Result: There are fundamental differences between these theories, but all of it can explain the genetic and environmental that influences regulation of body weight and obesity. Both in set point and settling point theory, the presence of physiological control systems and behavior plays important key to understanding theory of relativity body weight.
Conclusion: Genetics and environment are difficult to evaluate separately as both factors can influence the regulation of energy balance. Set point theory argues that obesity is caused by physiological factors and setting point argues that external factors are more dominant.
