A new study of how physical activity impacts the metabolism of humans suggests that increasing levels of activity may bring diminishing returns in energy expenditure.
This is due to “compensatory responses in non-activity energy expenditures,” international researchers wrote in the study, published in August in the journal Current Biology.
For every 100 calories burned as a result of working out, the study says most people will net fewer than 72 calories burned.
“This suggestion has profound implications for both the evolution of metabolism and human health. It implies that a 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.
