Physical activity has many health benefits, but if you're looking to lose weight, intense exercise may not be enough to lose weight. Experts believe that the body is able to adapt to increased levels of physical activity, and as a result, even in conditions of intense training, it will not be possible to burn more calories. will tell what prompted the specialists to such an idea, as well as what method of losing weight they consider the most effective.

Why a high level of physical activity will not provide the maximum effect

Researchers have found that, on average, a person burns only 200 more calories during moderate physical activity than during a sedentary lifestyle. However, even the most physically active people burned the same number of calories on average as moderately active people.

Researchers are not yet able to accurately explain the reasons for this phenomenon.

Herman Pontzer, assistant professor of anthropology at the City University of New York, said that the benefits of exercising for weight loss have not been canceled, but exhausting workouts will not necessarily provide the best results in terms of calories burned. Pontzer noted that while adapting to higher levels of physical activity and work, the body is simultaneously adapting to a new pattern of energy expenditure.

The study measured physical activity and calorie burn in 332 volunteers, ranging in age from 25 to 45, over the course of a week. The study involved people from Ghana, South Africa, the Seychelles, Jamaica and, of course, the United States.

There is a small but measurable relationship between the level of physical activity and the number of calories burned per day. However, this association was only found when people who were almost completely sedentary were compared with those who were physically active, who burned an average of 200 calories more per day.

In contrast, the most physically active volunteers burned almost the same number of calories per day as the moderately active participants in the study.

Scientists have previously investigated the relationship between activity levels and energy expenditure in the Hadza (hunter-gatherer) people of northern Tanzania. 

"Hadza People– very active people, they cover long distances every day, and also do a lot of hard work every day. Despite these high levels of physical activity, it has been found that the daily energy expenditure of the Hadza people is the same as that of people living a modern, more sedentary lifestyle – residents of the USA and Europe,” Pontzer stated.

Optimal level of physical activity for weight loss

According to Pontzer, the lion's share of the calories burned by the body daily is spent not on physical activity, but on "the main work of cells, which is necessary to maintain life processes." Such work includes transporting nutrients and waste products to and from cells, as well as, for example, maintaining electrolyte balance.

Therefore, according to the researchers, increasing the level of physical activity causes the body to adapt and spend less energy on the above activities, thus allocating slightly more energy to physical activity.

Therefore, the scientist gave advice to those who are losing weight: "Intensive sports & ndash; not the easiest way to lose weight, for maximum results, you will need to monitor nutrition.

Thus, it is the golden mean of physical activity that is optimal for weight loss: you need to fight against a completely sedentary lifestyle, but it is not at all necessary to exhaust yourself with intense training for weight loss – the effect will be minimal. Moderate physical activity along with proper nutrition is enough for most people to maintain optimal weight and shape. reminds that the cause of weight gain, as well as difficulties with losing weight, can be individual characteristics of the body, as well as various diseases. That is why, for maximum effect, it is better to consult a specialist who will determine which weight loss plan will be the most effective and harmless for you!
