What Is Kcal? How Do We Measure It?

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 🗗)

Measure KCAL

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 🗗)

Energy Comes From Food

The energy we consume comes from carbohydrates, protein, fats, and alcohol. (source 🗗)

More than 95% of food's energy is digested and absorbed from the gastrointestinal tract to provide the body's energy needs. (source 🗗)
