What are calories?

A calorie is a unit of energy. It is defined as the approximate amount of energy needed to raise the temperature of one gram of water by one degree Celsius at a pressure of one atmosphere. One calorie (cal) is a really small amount, so in everyday life we use kilocalories (kcal), which is one thousand of calories. In this article, we use the term "calories" to describe kilocalories, which is quite a common practice.

What factors affect calories burned and weight loss?

There are three main factors in calculations of burned calories and weight loss:

• body weight - the more you weight, the more you burn, as you use more energy to move a heavier body
• exercise intensity and duration - more extended and more intense activities burns the calories faster
• choice of the exercise - it's intuitive: we know that recreational biking, mountain race (check our cycling breakaway calculator) and stationary cycling, each practised for 30 minutes, will give different results

How many calories does biking burn?

To calculate the calories burned, we need to know how to assess intensity and evaluate choice of the exercise. The easiest and most objective way to assess this is using your power output. If you don't have a powermeter on your bike we recommend you to use out cycling wattage calculator to help you obtain this number.

In this case, the formula to obtain your calories consumed takes into account your average power (Power) and the time of the activity (T):

calories = ((Power * T) / 4.18 ) / 0.24

where 4.18 is the conversion factor from Joules (SI unit) to calories, and 0.24 is the efficiency (24%) of an average human body when cycling.

However, you might not have the time to do those calculations, or maybe you're looking for a simple estimation. Here is where the units "MET" appear. METs (Metabolic Equivalent of Task) are expressing the energy cost of physical activities. Simply, they measure how many calories you burn per hour of activity and per one kilogram of body weight.

For example, MET for leisure biking is equal to 4, and the value for somebody taking part in a race and cycling over 20mph can be as high as 16. Therefore, choosing only the type of activity is not enough - in other calculators, you can usually find the one MET value for biking equal to 8 or 8.5, which is an averaged value for all types of cycling.

Calories burned biking calculator uses the formula for calories burned:

calories = T * 60 * MET * 3.5 * W / 200

where T is the duration of activity in hours, W is your weight in kilograms, and MET is a metabolic equivalent of the chosen task.

To calculate the weight loss, we need to know how much energy our fat tissue contains - there are approximately 7700 calories stored in every kilogram of body fat. It means that once you've found the number of burned calories, all you have to do is to divide by 7700 to obtain the weight loss in kilograms:

weight_loss = calories/7700

Cycling for weight loss

You want to lose some weight, but you still hesitate: which activity is better? Half-day trip biking for 5 hours in leisure pace or 1.5-hour stationary biking with a heavy load? Thanks to our calculator you can assess which form of biking activity may serve you best:

1. Choose the type of biking you are considering, e.g., bicycling 12-13.9 mph leisure, with moderate effort.
2. Enter your weight into the calories burned biking calculator. Let's assume it's 80 kg.
3. Next, determine the duration of the activity. Let's say you went for a half-day trip and were biking for 5 hours.
4. Input all of these values into the calorie burn formula:

calories = 5 * 60 * 6 * 3.5 * 80 / 200 = 2520 kcal

1. Finally, divide this value by 7700 to obtain your weight loss:

2520/7700 = 0.33 kg

Repeat the steps for second activity, changing only the form and duration - the results for 1.5-hour stationary biking with a heavy load is 1323 kcal burned and 0.172 kg weight loss. Tadaaam! The calories burned biking calculator helped you figure out which form of biking is more profitable.

How does biking affect your weight loss?

Biking helps to burn calories and increase the heart rate and aids in weight loss. For people who cannot do exercise because of pressure on joints can do biking as that does not put pressure on your knees and will help in losing weight

How Can I Use the Calories Burned Biking Calculator to Lose Weight?

It is evident from the calculator that the more we involved in biking the more calories will be burned and it gives us a fair idea for the intake of food to be taken in a day. Many studies suggests that the lower the calorie intake the higher would be the weight loss. So once you start using this biking calculator you can estimate the number of calories required in a day.

How does incline (downhill / flat / uphill) impact your calorie burn

Downhill and flat surfaces are easy to bike and do not need more strength whereas uphill needs more strength as you go against the gravity. Hence, you burn more calories biking uphill than flat or downhill.

Which One Burn More Calories Biking Vs Running Vs Walking

All the three i.e biking , running and walking are the best physical activities.However running is more effective in burning calories.

According to American Council of Exercise if a person weighs 140 pounds then he is likely to burn 13.2 calories per minute running and that same person would burn 7.6 calories

approximately per walking.So we can figure out that calories burned during running are almost double to that of walking.

Likewise if a person weighs 150lbs and goes for a 1 hour of run at a speed of 5mph for 5 miles he is likely to burn 593 calories compared to the same distance of of biking which will burn around 250 calories.

You burn more calories in running compared to cycling and walking

Do you burn more calories sitting or standing while cycling?

Most of us prefer sitting while cycling but it does not helps in burning more calories.But we all know that standing would be more preferred and if it is coupled with cycling it burns more calories as it helps to increase heart rate and improves the core muscles which would be very effective in the long run.
