K Calorie

A kilocalorie (kcal), often called a calorie, is a unit of energy used to measure the amount of energy your body needs to function and process food. When you eat, your body converts the food into energy that powers your activities, from breathing to exercise. Essentially, a kcal tells you how much energy is contained in food or burned during activity. Consuming more kcal than your body uses over time can lead to weight gain, while a balance helps maintain your current weight. It’s a standard measure to help understand and manage dietary energy intake.
