The MET value of an exercise is higher the more energy an activity requires. This measure tells you how many calories you burn per hour of activity and per one kilogram of body weight. This energy expenditure is typically expressed in MET - the Metabolic Equivalent of a Task.
The number of calories burned walking is smaller than running or cycling. But when we talk about consuming calories we tend to think more about the conscious act of exercising and expending extra energy compared to the normal or basal metabolic levels.Īs you may have guessed, every exercise needs a different amount of energy.
The energy is consumed in activities such as pumping blood through our system, processing food in our digestive system and even thinking (the brain burns about 20% of our daily calories). This includes those times in which we are apparently doing "nothing" since, fortunately for us, our body is still functioning and consuming energy. Since calories are, effectively, energy, any time energy is used or transformed in our body, we consume calories. We will go a bit more into details in a later section, for now, let's focus on the calculator. However, this is just an oversimplification since "calories in vs calories out" is not the whole story when it comes to weight loss. This equivalence is what allows the burned calories calculator to predict the weight loss derived from a certain exercise. Each kilogram of body fat stores about 7700 kcal. There is a simple way to calculate calories from fat, which is based on the energy density of body fat. Fat is not necessarily a bad thing, as we explained in our healthy body fat calculator Body fat is the way our body stores energy for times of necessity, that is, body fat is how we store those extra calories that we ate but never burned. This is because body fat and calories are very closely related. When you mention calories, people immediately think about nutrition, weight loss, and even health problems associated with being overweight, such as heart disease. In this article, we use the term "calories" to describe kilocalories for simplicity. This kilocalorie is often called large calorie, Cal or Calorie (with capital 'C'). In nutrition, we actually deal with kilocalories (kcal), where 1 kcal is equal to a thousand "small" calories. In modern times the definition of a calorie has been tuned and improved to a more reliable and repeatable one until we have arrived at the current: 1 calorie is equivalent to 4.18 joules. The definition of a calorie is the energy required to raise the temperature of 1 gram of water by 1C.
Traditionally, it was a fairly common unit of energy, but nowadays it's been relegated to describe almost solely nutrition and the energy content in food. Put simply, calories are a measure of energy.
