A unit of heat used to measure the energy content of food, a calorie is the amount of heat required to raise the temperature of 1 g of water by 1°C

Real World Example

Imagine you're trying to fill a bucket with water using a small cup, and each trip only adds a little to the bucket. This process is similar to how calories work, as each calorie is like a small cup of energy that, when added together, fills up your body's energy "bucket." Just as it takes many trips to fill the bucket with water, it takes many calories to provide your body with the energy it needs, with each calorie being the precise amount of energy required to raise the temperature of 1 gram of water by 1°C.
