CAUSES OF OBESITY Obesity cigarette result from a minor free energy dissymmetry, which lead to a gradual but persistent weightiness gain oer a considerable period. Some researchers nourish hypothesized that energy imbalance is the result of inherited metabolic characteristics; whereas others believe it is caused by sad eating and lifestyle habits, that is gluttony and sloth. Positive energy balance occurs when energy breathing in is greater than energy white plague and promotes weight gain (Figure 4). Conversely, negative energy balance promotes fall down in body avoirdupois stores and weight loss. Body weight is regulated by a series of physiologic processes, which maintain the capacity to maintain weight within a comparatively narrow range (stable weight). It is thought that the body exerts a stronger refutal against undernutrition and weight loss than it does against over-consumption and weight gain. Figure 4 overly suggests that positive energy balance and weight gains are influenced by powerful societal and environmental forces which may overwhelm the physiological regulatory mechanisms that operate to keep weight stable.

These include change magnitude automation, lack of recreational facilities and opportunities, increase in food salmagundi and availability. Moreover, the susceptibility of individuals to these influences is affected by genetic and other biologic factors such as sex, age and hormonal activities, over which they have little or no control (WHO 1998). Dietary intake and physical activity are important contributing factors in the development of obesity. If calorie intake is in excess of necessary it leave be stored mainly as body fat (Figure 4). If the stored body fat is not utilised over time, it will lead to overweight or obesity. Inter-individual variations in energy intake, base metabolic rate, spontaneous physical activity, the relative rates of carbohydrate-to-fat oxidation, and the degree of insulin...
