ABSTRACT

Energy regulation in human beings is a complicated matter with multiple interacting processes. The physiology of weight control in humans allows tight control. Changes in the environment such as increased consumption of energy- dense foods and lack of physical activity can disturb homeostasis and lead to weight gain and obesity. Lifestyle measures such as increased physical activity and consumption of nutritious, low- energy- dense food can play an important role in lowering the risk of obesity. Individuals who have a genetic predisposition to weight gain and obesity should be particularly be cognizant of the importance of lifestyle measures such as increased physical activity and proper nutrition.
