Story summary

A study published in Current Biology finds that elite athletes cannot consistently exceed the body's metabolic limits.
The study analyzed 14 trained athletes and found they rarely burned more than 4,000 calories per day, averaging 2.4 times resting metabolic rate.
During intense events, such as a nearly 24-hour run, some athletes briefly exceeded this rate, but the elevations were brief, indicating a metabolic ceiling and alignment with prior studies.
