The study reveals a main cause of obesity and is not lack of exercise

Obesity among adults remains an important public health problem in the United States and other economically developed countries, according to disease control and prevention centers (CDC) and the World Health Organization (WHO).

“It is a mixture of bad diet, high levels of stress, lack of muscle and lack of frequent movement,” Lindsay Allen told News News News, a recorded dietary nutritionist of Back in Balance Nutrition in Florida.

While so much eating in excess and lack of exercise are often guilty, a new global study suggests that one factor far exceeds the other.

Scientists studied more than 4,000 adults in 34 populations, from hunter-gatherer communities to office workers.

They analyzed the total energy expenditure of each person (TEE), which is the number of calories burned daily, together with the percentage of body fat and the BMI (body mass index).

When they adjusted for body size, people in all lifestyles and income levels burned similar amounts of energy, even if their daily routines were drastically different.

“The differences in the body fat that we see in all populations are probably not due to the big differences in the level of activity or total daily energy,” said the authors of study Amanda McGrosky (from the University of Elon in North Carolina) and Amy Luke (University of Loyola in Illinois) to News Digital.

“Rather, excess body fat is probably mainly the product of too many ‘calories’ or eating more calories than they burn.”

Scientists may have discovered why pounds come back after losing weight

People in more economically developed areas burned more calories, the researchers said, but that is mainly because they tend to weigh more and the heaviest bodies burn more energy.

Published in the magazine Acts of the National Academy of Sciences (PNA), the study concluded that the number of people who eat plays a much greater role than the amount of exercise when it comes to gaining weight.

“Our analysis suggests that the increase in energy intake has been approximately 10 times more important than the decrease in activity rates to boost the modern obesity crisis,” said the authors.

Dr. Brett Osborn, a Florida neurosurgeon and longevity expert, agrees with the adage that “a bad diet cannot be overcome.”

“The exercise burns much less calories than people want to believe,” said Osborn, who did not participate in the study, News Digital.

“We are not gaining weight because we stop moving. We are winning because we are supercharged.”

“These latest data only confirm what I have seen in my clinic: we are not gaining weight because we stop moving. We are winning because we are overwhelmed.”

Allen said that muscle mass should also be considered.

“Having enough muscle is what drastically improves metabolism and fat burning capabilities,” Digital’s News told News, which also emphasizes the importance of stress levels. “People who live in high stress societies tend to be fatter because stress hormones change our metabolism and change us to the ‘survival mode’.”

Another finding implies ultraprocessed foods (UPF), which have lists of long ingredients that are often dense in calories, stable and “highly tasty.”

“As more populations are exposed to increasing amounts of highly processed and highly tasty foods, we will probably see increases in obesity in regions with relatively low rates,” predicted the authors of the study.

Ultraprocessed foods tend to be easier to eat in excess due to their flavor and texture, and do not keep people fallen, according to the study.

They are also densest in calories, which means that they pack more energy in smaller volumes, and are absorbed more easily, which makes it difficult for the body to eliminate excess energy.

“Ultraprocessed foods are designed to cancel our biology, namely our satiety signaling in the brain,” Osborn told News Digital. “They also promote inflammation and change our physiology to a state that favors the accumulation of fats on fat burning.”

The researchers pointed out that physical activity remains important, particularly for cardiovascular health, mental well -being and longevity.

Allen said that people “need to consider all the other benefits of exercise and move away the mentality of how many calories are burning (which does not really work very well for weight loss) to develop so much strength and possible muscle.”

Osborn agreed, recommending “progressively intense and challenging training”, strength training in particular, to help increase the metabolic rate and facilitate fat burning.

“As I always tell my patients,” by virtue of adequate nutrition and strength training, your body will not burn fat, but also burn fat quickly. “

However, Allen pointed out, when it comes to preventing obesity, findings point to excessive calorie consumption, particularly ultraprocessed foods, such as the main contributing factor.

“If you worry about excess body fat, make up in calories,” McGrosky and Luke advised. “Especially in the long term, it is much more difficult to change significantly the total number of calories that burns that changing the amount of calories it receives.”

Osborn added that the problem is not laziness or lack of movement.

“It is the constant flow of ultraprocessed and empty products of nutrients that are impaled in the mouth under the appearance of health or convenience,” he said. “And he is killing us, slowly, predictable and mass.”
