In fat cells that burn energy to make heat, there might be a cycle where creatine gets charged up and then drained over and over, releasing energy as heat and keeping the cells' energy engines running.
See the scientific wording
In thermogenic adipocyte mitochondria, a mitochondrial creatine kinase can catalyze the phosphorylation of creatine to phosphocreatine using ATP, resulting in local ADP release that stimulates respiration, while a phosphatase hydrolyzes phosphocreatine back to creatine, enabling a continuous futile cycle that may contribute to energy dissipation.
Correlational — new studies may shift this
One low-scoring study links this claim to the outcome, but causation is not established.

Mechanism of futile creatine cycling in thermogenesis.
Narrative ReviewReview2020
The study shows that in fat cell mitochondria, creatine can drive a cycle that burns energy and produces heat, just like the claim says, by repeatedly turning creatine into another molecule and back again.

No contradicting studies found yet
That doesn't mean it's settled — it just means no study has tested the opposite.
Quality-weighted scoring: we follow the GRADE framework — each study is rated High, Moderate, Low, or Very Low based on study design, methodology rigor, and risk of bias. A single high-quality RCT can outweigh several weaker observational studies.
Scores reflect study quality, not just count.
