Obesity among adults remains a major factor Public Health It is published in the United States and other economically developed countries, according to the Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO).
“It’s a mixture of poor diet, high stress levels, lack of muscle and lack of frequent movement,” Lindsay Allen, registered dietitian nutritionist and owner of Back in Balance Nutrition in Florida, told Fox News Digital.
Both are overeating Lack of exercise Many should be responsible, new global studies suggest that one factor far outweighs others.
Your DNA may be stopping you from losing weight, new research suggests
Scientists have studied more than 4,000 adults from a population of 34 people, ranging from hunter-gatherer communities to office workers.
They analyzed each person’s total energy expenditure (TEE). This burns along with the number of calories burned daily, body fat percentage and BMI (body mass index).
Adjusted to body size, people of all lifestyles and income levels, even if they burned similar energy Daily routine It was dramatically different.
“The differences in body fat seen between populations are probably not due to significant differences in activity levels or the total energy burned per day,” study authors Amanda McGroski (Elon University, North Carolina) and Amy Luke (Loyola University, Illinois) told Fox News Digital.
“In fact, excess body fat is primarily “too many calories” or Eat more calories More than being burned. ”
Scientists may have discovered why pounds return after losing weight
People in more economically developed regions burned more calories, the researchers noted, mainly because they tend to measure more weight, and the heavier bodies naturally burn more energy.
The study, published in the Proceedings magazine of the National Academy of Sciences (PNAS), concluded that at that point, how much people eat plays a much greater role than exercise. Put your weight on.
“Our analysis suggests that increased energy intake is about ten times more important than lower activity rates in driving modern times. Obesity crisisThe author stated.
Dr. Brett Osborne, a Florida neurosurgeon and longevity expert, agrees with the saying, “You can’t kick out bad food.”
“The exercise burns far fewer calories than people want to believe,” Osborne, who was not involved in the study, told Fox News Digital.
“This latest data is only what I saw in the clinic. I stopped moving, so I haven’t gained weight. We’re gaining because we’re over-done.”
Allen pointed out that muscle mass should also be considered.
“Having enough muscle dramatically improves metabolism and fat burning ability,” she told Fox News Digital, highlighting the importance of stress levels. “People who live in stressful society tend to get fat Stress hormones Change your metabolism and move to “Survival Mode.” ”
Scientists can detect junk food consumption in blood and urine tests
Another discovery includes ultra-high processing foods (UPFS). This has a long list of ingredients that are highly calorie-densed, shelves-stability and “very tasty” ingredients.
“As more population is exposed to an increasing amount Highly processedvery tasty foods, and there is a high chance that there will be an increase in obesity in areas that are currently relatively low,” the study authors predicted.
Ultra-positive foods tend to be easier to eat in excess due to their flavor and texture, and also keep people from continuing to feel full, research found.
Additionally, the higher calorie density means it packs more energy into smaller amounts, making it easier for your body to absorb and make it difficult for your body to eliminate excess energy.
“Ultra-positive foods are designed to negate our biology: satiety in the brain,” Osborne told Fox News Digital. “They also promote inflammation and shift our physiology to a state that supports fat accumulation rather than fat burning.”
Researchers noted that physical activity in particular remains important Cardiovascular healthmental happiness and longevity.
Allen said people need to “shift towards building as much strength and muscle as possible, considering all the other benefits of exercise and from the number of calories they burn (which actually doesn’t work very well for weight loss).”
Osborne agreed, recommending “gradually intense and challenging training” – especially strength training – to increase metabolic rates and promote fat burning.
“As I always tell my patients,” thanks to proper nutrition and strength training, your body will not only burn fat, but also fat burn faster. ”

However, Allen pointed out that excessive calorie burn, especially ultra-highly processed foods, as a major contributor when it comes to preventing obesity.
“If you’re worried about excess body fat, focus on calories,” advised McGroski and Luke. “It’s much more difficult to change it meaningfully than changing the number of calories, which means the total number of calories burned, especially in the long run.”

Osborne added that the issue is not lazy or lack of movement.
“It’s a constant stream of ultra-highly processed nutritional products that are pushed into your mouth under the guise of health and convenience,” he said. “And that’s killing us – slowly, predictably, and in abundance.”
