In this paper, researchers aimed to characterize circulating metabolite excursions during an oral glucose tolerance test (OGTT) and evaluate whether the metabolomic signatures of BMI discordance coassociate with LF content.

Results found that BMI-discordant MZ twin pairs who also are discordant for LF have more pronounced within-pair differences in metabolomics profiles during an OGTT than BMI-discordant pairs without LF discordance.
