Why do athletes burn more calories at rest?
Interaction of acute changes in exercise energy expenditure and energy intake on resting metabolic rate.

Athletes don’t naturally burn more calories at rest — it only happens when they’ve just exercised and eaten enough to match that energy use.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

When the body processes a large amount of energy from food and physical activity, it burns more calories at rest, breaks down more fat, and reduces feelings of hunger, regardless of whether total calorie intake exceeds or falls short of expenditure.
In physically trained men, performing intense exercise for 90 minutes a day over three days while maintaining normal calorie intake is linked to a higher resting metabolic rate compared to days without exercise, even when calorie intake is unchanged.
In trained men, resting metabolic rate increases only when both physical activity and food intake are high and balanced, not when calorie intake is higher or lower than expenditure alone.
Men who are physically trained have a higher resting metabolic rate than untrained men, but only when their bodies are processing a large amount of energy at that moment. This difference is not a permanent feature of training but depends on current energy use.
In people who train regularly, a higher resting metabolic rate is not due to long-term changes from exercise, but rather to temporary increases in energy use during and after intense activity. When those high-energy conditions are removed, the metabolic rate difference between trained and untrained individuals disappears.
