How Do I Know If I Am Eating Too Few Calories? Its Symptoms

Calorie is the unit used for measurement of energy released when the consumed food is broken down during digestion. Calorie is a unit referred in pounds or grams. The food that we consume is made up of principal nutrients such as protein, carbohydrate and fats. During the process of digestion food is broken down in smaller unit which is then converted into energy.

The amount of energy available from the food is called energy input.

Human body needs certain amount of energy to perform even basic physiologic functions such as breathing, digestion, and various other activities in daily life. If you do not eat enough calorific food to meet such basic physiological needs of the body, you are at risk of suffering from various physical and mental ailments.

BMR is basic metabolic rate. It is the amount of calories that is needed for basic function of the body when it is resting. Functions such as breathing, blood circulation, body temperature also consume some amount of energy.
