Scientists have identified factors that affect calorie burning during exercise

Various factors affect calorie burning

Every time we try to lose weight, choose the intensity of exercise, or take care of our health, we hear about calories. Perhaps everyone has been interested in counting them at different times in their lives. And rightly so, since a calorie is the basic unit of energy used by our body not only during active exercise but even during sleep. Everyone burns calories in their own way, and we can't influence everything.

All the processes in the body that are responsible for the breakdown of nutrients for energy make up a person's metabolism, and everyone has a unique one. The EveryDayHealth publication has told us what factors affect calorie burning.

Metabolic processes are extremely complex and are influenced by a variety of factors, so you shouldn't focus on someone else in terms of weight loss or muscle gain. According to experts, there are several factors that have the greatest impact on calorie burning.


It is common knowledge that the more you weigh, the more calories you burn. This is due to the fact that even the normal movement of your body takes more energy when you are overweight. In addition, your internal organs are also larger, so they require more energy to function both during exercise and at rest.

This fact explains why losing weight is slower or may even stop if you are lighter. At the same time, it should be remembered that even a slowdown in weight loss is not a reason to give up training, as, according to scientists, improving cardiorespiratory endurance is good for overall health, reducing the risk of premature death.

Muscle mass

According to sports nutritionist Jenaed Brodell, MD, muscle tissue burns more calories than fat tissue. That's why muscle-building exercises are effective for burning more calories (as your body needs to produce more energy to maintain the speed at which your muscles contract).

That's why, if you want to speed up your calorie burn, you should consider increasing the intensity of your strength training.


Usually, regardless of the intensity of physical activity, men burn more calories than women. This is due to their higher body weight and muscle mass from birth. Therefore, even at rest, they are able to burn 5-10 percent more calories than women.

In addition, women are physiologically predisposed to store more fat for hormone production and the ability to bear children. Therefore, some evidence suggests that men need at least 2-5 percent body fat and women need at least 10-13 percent to maintain overall health.


Over the years, people tend to lose muscle mass, which in turn leads to a slower metabolism. This may be due to the fact that the body becomes more resistant to hormones that synthesize protein production, a necessary element for maintaining muscles.

At the same time, this does not mean that calorie burning will continue at the same level throughout adulthood. Research shows that metabolism stabilizes between the ages of 20 and 60 and only then begins to decline. This means that through regular strength training, you can increase muscle mass, which will help you burn more calories even at rest as you age.

Physical fitness level

You've probably noticed that exercising becomes easier with time. This can be explained by the fact that the body adapts to the chosen load. However, this also affects calorie burning.

Since you need less energy to achieve your goal after adaptation, you burn fewer calories during your workout. That's why you need to review and increase the intensity of your physical activity to get results.

Training intensity

The intensity with which you perform your exercises is of great importance. After all, two people will burn different amounts of calories doing the same exercise at different intensities.

Even low-intensity workouts will have positive effects on your overall health, including reduced anxiety and improved cardiovascular health. However, adding high-intensity exercise will only improve these effects and increase calorie burn.

As you can see, metabolism is a complicated process in the human body, and there is no need to worry about what we cannot influence. However, knowing certain rules and regular physical activity will not only help you burn accumulated calories but also significantly improve your health, prevent the progression of diseases, and maintain your health for many years.
