A new study on how physical activity affects people’s metabolism suggests that increased levels of activity may lead to diminished returns to energy expenditure.
In the study, published in August in the journal Current Biology, international researchers wrote that this is due to “compensatory responses in non-activity-related energy expenditures.”
This suggestion has profound implications for both metabolic evolution and human health. This indicates that the long-term increase in activity does not directly translate into an increase in total energy expenditure (TEE) because other components of TEE may decrease in response – energy compensation,” the study summary notes.
The group found that for the 1,754 adults living a “normal life,” the average energy compensation is 28% due to lower basic energy expenditure (BEE) and that “this indicates that only 72% of the additional calories we burn are from The extra activity translates to burning extra calories that day.”
BEE is the number of calories burned once you are alive.
Researchers have subtracted figures from TEE to understand energy expenditure from exercise and other movements and its use Statistical modeling to draw these conclusions.
In addition, the degree of energy compensation for different body compositions varied widely.
The study suggests that the reason may be due to inter-individual differences in caloric compensation, as people who compensate are more likely to accumulate body fat.
Instead, the researchers said, the process may be within individuals — bodies more aggressively compensating for calories burned during activity and doing. Weight loss more difficult.
The study states that, “Determining a causal relationship between energy compensation and obesity will be key to improving public health strategies in relation to obesity.”
Notably, the study did not examine food intake.
US Centers for Disease Control and Prevention (CDC) It notes that the prevalence of obesity in adults in the United States was 42.4% in 2017 to 2018.
Obesity also affects some groups more than others, with non-Hispanic black adults having the highest prevalence of obesity by age followed by Hispanic adults and non-Hispanic white adults.
Another study was published this month in iScience He points to increased physical activity and improvements in fitness levels as key to reducing the risk of obesity-related health conditions and mortality — even with no weight loss.
“We propose a weight-neutral strategy for the treatment of obesity on the following grounds: (1) the risk of obesity-related death is substantially mitigated or eliminated by moderate to high levels of cardiorespiratory fitness (CRF) or physical activity (PA), (2) Most markers of obesity-related cardiometabolic risk can be improved by exercise training independent of weight loss and in an amount similar to that observed in weight loss programmes, (3) weight loss, even if intended, is not consistently associated with lower weight mortality risk, (4) Increases in CRF or PA consistently correlate with greater reductions in mortality risk than intentional weight loss, and (5) weight riding is associated with many adverse health outcomes including increased mortality,” the University of Arizona and the University of Virginia authors wrote.
“Adherence to PA and CRF may improve if healthcare professionals consider PA and CRF as essential biomarkers and consistently assure their patients the many benefits of PA and CRF in the absence of weight loss,” they said.
