State Of Nutrition
The state of nutrition depends mainly on the distribution of adipose tissue or fat, in the body- On this basis, individuals can be classed as normal, overweight (fat or obese) and underweight (thin or lean). Factors regulating body weight have not been clearly elucidated.

Being underweight or obese arc problems of metabolism, dependent on caloric intake, energy expenditure, metabolism of fats, proteins, carbohydrates, minerals and water, appetite, mode of life, endocrinal factors, heredity, constitution, personal habits, upbringing and environmental factors.

Obesity
The term obesity is applied to excessive deposition or distribution of fat in the body. Excess of fat is a disadvantage rather than an asset; it may lengthen the waist line, "but shortens the life line" of the individual by imposing an extra burden on the cardiovascular system. Exogenous or alimentary obesity, from over eating, is far more common than glandular or endogenous obesity. Obesity may be mild, moderate or severe.
