The Claim

Resting energy expenditure remained stable or slightly decreased in two athletes during a 30-day ultra-endurance ride despite high physical activity levels and changes in body composition.

Description
1 study reviewed
In plain English

In two athletes undergoing a 30-day ultra-endurance ride, resting energy expenditure did not increase as expected despite high physical activity and changes in body composition.

See the scientific wording

Resting energy expenditure remained stable or slightly decreased in two athletes during a 30-day ultra-endurance ride, despite high physical activity levels and changes in body composition, suggesting metabolic adaptation to prolonged exertion.

Why this might work

The body burns less energy at rest by making its cells more efficient at using fuel, reducing wasted heat production and relying more on fat for energy instead of burning through sugar too quickly.

    Even though these cyclists burned tons of energy every day for a month, their bodies didn’t burn more calories at rest — they just got better at using energy efficiently.
