The Claim

Non-exercise activity thermogenesis (NEAT) responses to weight loss in former elite athletes exhibit large interindividual variability, with a standard deviation of 24 kcal/day at 12 months, which exceeds the smallest worthwhile change of 87 kcal/day, indicating that measurement error or within-subject instability accounts for much of the observed variation.

Description
1 study reviewed
In plain English

After losing weight, former elite athletes show large differences in how much they move spontaneously, and these differences are larger than what would be considered meaningful, suggesting the changes observed are likely due to measurement inconsistency or natural fluctuations rather than true biological change.

See the scientific wording

There is large interindividual variability in non-exercise activity thermogenesis (NEAT) responses to weight loss in former elite athletes, with a standard deviation of 24 kcal/day at 12 months, which exceeds the smallest worthwhile change of 87 kcal/day, suggesting measurement error or within-subject instability may account for much of the observed variation.

Why this might work

After weight loss, the brain's control over small, automatic movements becomes less consistent, causing some people to move slightly more or less on different days without any clear reason, making changes in calorie burn appear random and unreliable.

  1. Study: Interindividual variability in metabolic adaptation of non-exercise activity thermogenesis after a 1-year weight loss intervention in former elite athletes

    After losing weight, some former athletes moved a bit more and others a bit less, but the differences were so small and inconsistent that they probably weren’t real changes—just noise from measurement or random day-to-day fluctuations.
