DexaFit Research is the research and publishing arm of DexaFit. We publish original research and curate findings from leading journals in the fields of body composition, metabolic health, and longevity science. We make data available to researchers, clinicians, and product teams. We provide real-world evidence at a scale published cohorts can't match.
Most body composition reference data is decades old, based on small samples, or measured with imprecise methods. DexaFit's clinical network generates hundreds of thousands of DXA, VO₂ Max, and RMR scans with high-fidelity labels and demographic context.
Every original research article is reviewed by at least one domain expert. We use the term "expert-reviewed" rather than "peer-reviewed" to acknowledge that our review process is rigorous but distinct from traditional journal peer review.
Methodology, limitations, and conflicts of interest are disclosed on every page. Curated content from outside sources is annotated with DexaFit context, caveats, or opposing viewpoints when appropriate.
All data is de-identified per HIPAA Safe Harbor standards. No individually identifiable health information is published. We perform automated quality checks on all measurements, validate scanner calibration regularly, and stratify results by demographic variables to identify potential biases.
Known biases, limitations, and sources of error are disclosed alongside our findings.

DexaFit Research is funded by DexaFit, a commercial testing company. Research is produced by the same organization that operates the clinical testing network. This creates inherent conflicts of interest.
We do not suppress unfavorable findings. All methodology and limitations are disclosed transparently. Our commitment is to advancing the science of body composition measurement and interpretation, not to promoting DexaFit's testing services.
