Portion control is very important for weight management as the individual's weight is defined by the total calorie intake.

Healthy eating (and lifestyle) is the desirable middle between two extremes of excess and the other of deficiency (over eating and not eating enough), the "golden mean." Portion control is eating a healthy balance of amount and types, of varied foods.
