A study published in PNAS found that increased physical activity leads to higher daily calorie burn without the body compensating by reducing energy use elsewhere, supporting an additive model of energy expenditure.
A study published in PNAS shows that increased physical activity leads to higher daily calorie burn without the body compensating by reducing energy use elsewhere, supporting the idea that exercise adds to overall energy expenditure rather than redistributing it. The research involved measuring energy use in participants with varying activity levels and found that more active individuals burn more calories overall, with less time spent inactive, although further research is needed to understand potential energy compensation under different conditions.
