Calculating calories burned during various kinds of activities is a fairly simple matter as it revolves around the following equation:
Calories burned = MET × Weight (kg) × Time (hrs)
MET, short for metabolic equivalent, is the amount of oxygen used for particular activities, such as running, walking up the stairs, or cycling. You can check here the
70 × 7 × 1 = 490 calories. Although this result is only approximate, it can serve as a good starting point for our further calculations.
Back in 2002, a group of researchersin the Journal of Applied Physiology entitled, "Energy cost of walking and running at extreme uphill and downhill slopes". They put a group of volunteers on a treadmill and started testing how much oxygen they use at different gradients, starting from the flat walk or run and climbing higher and higher.
After thorough research, they were able to determine how the slope of a hill or mountain affects the amount of oxygen used and, as a result, energy consumed. Having calculated that, they were able to come up with an equation that roughly allows comparing calories burned on a walk and a hike. From there, it was only a short way to use the aforementioned equation and calculate the energy levels for both climbing up and down.

If you're interested in the effects swimming has on your body, this swimming calorie calculator is the perfect tool for you. Use it to find out how effective swimming and other water activities are for weight loss.
We took the inspiration for this calculator from a very similar tool published several years ago on. And it goes like this:
Enter the length of your trail (one-way) as well as its elevation gain (the sum of every elevation hiked during the trail) into the hiking calculator. This information should be available online, as well as at the trail itself.
Add your body weight.
Enter your backpack's weight (skip if you're not taking one — though, how will you carry your food and water?).
Once you have those 4 numbers filled in, all calculations will be performed, and you'll see your approximate results.
Let's discuss a simple example to make things clear. Mark went on a hike last weekend, which lasted for 12 miles (19.3 km) in total (so 6 miles one-way) and featured a 2500 ft (762 m) elevation gain. Mark is pretty slim himself, weighing 150 pounds (68 kg) and carrying 18 pounds (8.15 kg) of backpack on his back. As you can see from the calculator, the trail averaged around 7.9% grade (remember to use the one-way distance — 6 miles).
Now that we have those numbers, we can calculate the number of calories burned on the way up and down. First, if Mark were to leave his backpack before the trail start, he would burn roughly 924 calories on the way up and 533 on the way down. In total — 1457 calories. Add the backpack, and the numbers go up — 998.5 kcal for going up and 575.5 kcal down. In total, Mark should expect to burn around 1574 calories during his hike.
Now, note that we based those formulas on research done in a lab and not on a mountain slope. This means many outside factors were not taken into consideration, such as Mark's stamina and individual predispositions, weather conditions, trail structure, and speed of hike. Unfortunately, we simply don't have a sufficient amount of data, so we can only offer approximate values.
Regardless, it should work as an interesting way to check the calories needed for each trail and could help hikers better prepare for their trips. Use the tool responsibly, and don't forget to take some water and food with you, even if you're headed just for a short walk. Best of luck!

Yes, hiking is good for losing weight. On average, steep and more demanding paths make for a fair amount of calories burned. However, running still makes you burn more calories. A very rough approximation of the calories burned is
450 kcal per hour of hiking. Compare it with
300 kcal for walking and
600 kcal for running.
If you weigh around
80 kg (
~180 pounds) and plan a
20 km hike with an elevation gain of
1000 m, you'll burn approximately
1200 calories. Remember that this number is just an estimate. However, if you are planning on losing weight (or just being healthy), you should definitely pack your backpack and hit the trail!
A lot! For a cross-country hike with:
4270 km; and
the calories burned are more than
200,000, corresponding to a weight loss of almost
30 kg. Needless to say, packing enough food (and water!) is a must.
3000 kcal worth of food. Even though this value is an estimate, if you are hiking for
30 km with an elevation gain of
3000 m, your body would burn
3000 calories. If you are not planning to lose weight, you should plan to bring with you an adequate amount of food.
