When we restrict calorie consumption significantly, our body goes into what is called "starvation mode". On top of that, calorie intake has a significant effect on the BMR of a person. On the other hand, we can lower our BMR by having a very sedentary lifestyle, which we do not recommend. Recover is the keyword here since, at rest, our body not only has to keep functioning like any other person's but also has to recover from the exercise and rebuild energy stores and muscle tissue with the consequent increase in BMR. When we exercise a lot, we need more calories to compensate for the expenditure during our activity and put our body into a more active rest state when the time comes to recover. Using very simplistic examples, we can take a look at how the BMR changes for a person. As you might have noticed, we have singled out athletes as having a much higher than average BMR, and that's for a reason: BMR is not a fixed value it can vary from person to person.

This value is surprisingly high in most people, being greater than 1000 kcal and even over 3000 kcal for professional athletes. Simply choose the I want to compare two activities option. They, however, help you easily compare the calorie consumption expected from different exercises and activities. The important thing to remember is that the MET values are not the be-all-and-end-all and should be taken with a pinch of salt. We do not recommend doing this unless you know what you are doing or using a comprehensive database of MET values. However, one can correct for this issue by simply customizing the MET value directly. The METs we have encoded into this tool are just a guide based on averages and typical values for an average person. For this reason, the calories burned calculator needs to be understood as an approximation and not as a precise measurement. This is an effect that this calculator does not take into account: intensity. There is a difference between going for a leisure ride with your kid and racing in a criterium, even if they both take the same time. MET is a metric that assigns a single value to a particular activity, but, as anyone that has run or cycled frequently knows, the same exercise can vary in intensity significantly depending on the effort. Let's now step back a little bit and look at how MET is calculated and what it really means. Nevertheless, the approximation simplifies calculations so much that a mere 5 percent difference is an acceptable price to pay.
What exactly is 1 MET, then? It is defined as the ratio of energy spent per unit time during a specific physical activity to a reference value of 3.5 ml O₂/(kg For example, sleeping has a value of 1 MET while running has a MET of 7.5, so much higher. You can check that by looking at the different MET values for the exercises included in this calorie calculator. 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, 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 by walking is smaller than by running or cycling and, e.g., burpees burn even more calories (see burpee calorie calculator). 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).īut 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. That includes those times when 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.
