Here's a study from 2017 showing that adiposity (basically having a gut and/or being overweight as far as I understand) correlates to elevated levels of Erythritol in the bloodstream. n=264 and the test subjects are all college freshmen so presumably in much better overall health than the subjects of the study that's been getting hyped in the news, so definitely looking like reverse causality here: https://www.pnas.org/doi/pdf/10.1073/pnas.1620079114 https://www.pnas.org/doi/pdf/10.1073/pnas.1620079114 Edit: From the paper - "Erythritol was shown to be synthesized endogenously from glucose via the pentose-phosphate pathway (PPP) in stable isotope-assisted ex vivo blood incubation experiments and through in vivo conversion of erythritol to erythronate in stable isotope-assisted dried blood spot experiments. Therefore, endogenous production of erythritol from glucose may contribute to the association between erythritol and obesity observed in young adults."
