KCAL, kilocalories is a unit of energy widely used in nutrition. When we eat and drink, we put energy into our bodies. Our bodies use up that energy through everyday movement. Every cell in our body requires energy to function in its optimal capacity. We need to nourish our body right. If we don’t get enough nutrients that calories provide, there will be negative consequences.

KCAL, A Measurement Of Energy
KCAL means kilocalories, or more commonly named just calories. That’s one way of measuring the amount of energy there is in a food or drink.
Food energy is used to meet the body's needs for protein synthesis, maintenance of body temperature, cardiac output, respiration, and muscle function. (source 🗗)
There are two ways to measure the amount of energy you can find in foods or drinks by kilocalories, KCAL or kilojoules, kJ. (source 🗗)
One kilocalorie is equivalent to 4.184 kJ. That’s the amount of heat required to raise the temperature of 1 kg of water 1°C at standard atmospheric pressure. (source 🗗)
