What is an online energy expenditure calculator?
This online energy expenditure calculator will help you quickly and easily calculate how many calories you burn during one or more sports activities. You can also find out the calorie expenditure of common daily activities such as cleaning the house, cooking or other household chores. This tool is ideal for athletes of all levels who want to track their energy expenditure and optimise their training plan and diet accordingly. It will also be useful to anyone interested in how many calories they burn during all their daily activities.
How to use the online energy expenditure calculator?
- Enter your gender, age, height and weight into the form.
- Select whether you want to calculate the total energy expenditure or the net energy expenditure of the sport:
- Total energy expenditure (total calories) includes the basal metabolic rate (1 MET).
- Net energy expenditure in sport (active calories only) does not include the basal metabolic rate (1 MET), which is useful for more accurate estimation of energy availability in other calculators.
- Click on the icon of the sports or home activity category you want to count. Then click in the text box and select a specific activity. Then, in the next box, tick the amount of time you spent on that activity.
- Then click the Calculate button and the calculator will show you the result.
- You can add another activity by clicking the Add Activity button.
- If you want to cancel an activity, just click on its orange icon in the overview.
How does the online energy expenditure calculator work?
The Metabolic Equivalent of Task (MET) is used to determine the energy expenditure during activity . The latter is a measure of a person’s energy expenditure. The value of 1 MET is defined as the amount of energy a person expends at rest (without movement). Movement activity increases the MET value. It is true that the more energy consuming the physical activity, the higher the MET value.
MET units of locomotor activities were obtained in laboratory conditions. At the very beginning stood a value of 1 MET, which was determined from the measurement of the resting oxygen consumption of a 70 kg, 40-year-old man. The result was 3.5 ml O2/kg/min or 1 kcal/kg/h. This value was then compared with laboratory-measured oxygen consumption during various activities. And these measurements then yielded the MET values found in the compendium of physical activities. Our calculator is based on this information. This will also take into account the information you enter into it, and then calculate the total or just active calories burned.
The MET value is the best possible estimate of the energy consumed during an activity, which is also used in research or various recommendations for physical activity.
Are the calculated figures really accurate?
The resulting values from the online calculator may not accurately reflect your actual energy expenditure and energy needs. The MET values on which the result is based were measured in laboratory conditions, which vary more or less from the environment in which we live and where we perform the activity.
Other factors come into play that calculators and formulas cannot take into account. Each person has quite different genetic makeup, hormonal environment, metabolic rate, body composition (ratio of body tissues) and is in a different physical and mental state. Training or various variations in the comparison of real and specified activity intensity also play a role. Environmental temperature and other external factors also have an influence.
For these reasons, take the result as the best possible estimate (based on available scientific data) to get an idea of how many calories you will burn with a given activity. If you are using a sports watch or other device that measures your calorie burn, it is also possible that these values will differ from those calculated by the calculator. This is because electronic devices work on different principles and determine the result differently.

Which methods can measure energy expenditure with the greatest accuracy?
Indeed, the real and accurate amount of calories burned is far from easy to find out. You would have to get hold of the staff in sports laboratories, where, for example, measurements are made using direct and indirect calorimetry. In the first case, the amount of heat produced by the body during metabolic processes is measured in an insulated chamber. Indirect calorimetry, on the other hand, involves breathing through a mask during activity, which measures the production of carbon dioxide (CO2). Outside the laboratory, the doubly labeled water method is used, which is based on drinking water containing rare isotopes of oxygen. Scientists can then calculate the body’s total energy expenditure by analysing the body’s excretion of these substances. This means that the person does not have to stay in the laboratory while the metabolism is being measured, but can go about his or her normal activities. However, this method is also very expensive and the average person does not have access to it.
While our calculator doesn’t offer the most accurate result possible, it will give you a good idea of approximately how many calories you’ll burn through physical activity. This will give you a better understanding of the energy requirements of different sports and everyday activities.
Is it even necessary to keep track of exactly how many calories we burn?
As part of a healthy lifestyle, most people just need to know the indicative values of their energy expenditure through physical activity, which they can find out, for example, using our calculator. But professional athletes are a different case, as they need to know as accurately as possible how many calories they burn with a given activity. For them, the other methods mentioned above are also used to determine the exact amount of calories burned. They then usually have coaches, nutritionists or physiotherapists on their team who can take the resulting values into account when planning recovery, training and tailored meal plans. It is thus one of the parameters taken into account during the development of an individual plan. It reflects the needs of the athlete in question, allowing them to achieve the best results.
Which supplements will increase calorie burn during sports?
Especially for weight loss, when we are trying to burn as many calories as possible through sport, fat burners can come in handy. You can choose a single-ingredient supplement or try complex products in which the effects of the individual substances complement each other. In both cases, you will find fat burners with or without a thermogenic effect. Thermogenic burners include caffeine, synephrine and green tea extract (EGCG). They work on the principle of warming up the body (speeding up metabolism), which can also be reflected in more calories burned during a workout. Complex thermogenic burners, which combine several of the above-mentioned substances in one product, have the greatest potential.
Examples of non-thermogenic fat burners include conjugated linoleic acid (CLA), which is involved in the body’s metabolism and can affect fat burning itself. Likewise, L-carnitine, which is involved in the transport of fatty acids (fats) to the mitochondria, where they are converted into energy. Fat burners work best when combined with exercise, where they can help increase caloric expenditure.

How to quickly and effectively replenish burnt energy after a workout?
After a workout, it is important to replenish energy and nutrients that are crucial for recovery processes. Muscles use the storage carbohydrate glycogen, which serves as a source of energy, to function. This can be depleted quite quickly during training, especially in the case of demanding and intense sports. Fast-digesting carbohydrates, such as maltodextrin, dextrose, Vitargo or the complex supplement FueCarb, will help with its effective replenishment. Thanks to the restored glycogen stores, you will gain energy for the next sports performance. This is especially important for people who exercise in two phases or who, after an evening workout, have another workout the very next morning.
Protein, which is a source of amino acids, also plays a key role after exercise. These function as the basic building blocks of muscle mass and are therefore necessary for muscle repair and growth. Post-workout supplements with essential amino acids such as BCAAs or EAAs are ideal. You can also supplement amino acids with an easily digestible protein such as whey protein or a gainer that contains carbohydrates in addition to protein.

So, how do I know how much energy to take in?
A number of factors need to be taken into account to set the optimal energy intake, such as age, height, current body weight, goals and the amount of exercise and sporting activities during the day. You can easily calculate this using online energy intake and macronutrient calculator. However, the value that the calculator will calculate for you is not final. It does not take into account your genetic makeup or your body’s hormonal environment. Therefore, you need to monitor over a period of weeks how your body reacts to the new diet and adjust your energy intake and macronutrients accordingly. This way, you will get the most out of this tool and achieve your sporting goals more easily.
