The understanding of the serving size of a food, and the number of calories present in it is referred to as portion control. Exercising portion control is extremely important for weight management. It involves eating the balanced amounts of all the nutrients and types of foods. Food pyramids are important aids that are used to guide people to help control their portions and eat a variety of foods. Objects can be used as a point of reference to estimate portion sizes. One method of measuring portion size is to use the size of a person?s hand as reference. For instance, one healthy portion of protein is equal to the palm size of meat or any other protein source. Similarly, carbohydrate servings are measured using fist. For instance, a healthy portion of pasta is one fistful. Various emotional factors such as depression and anxiety may lead to lack of portion control in individuals. Using small plates, sharing meals and planning meals ahead of time are some tips that can be used to follow portion control.
