Key result
Higher meal carbohydrates and lower fat proportions are linked to greater postprandial glycemic responses.
Why the study?
Studies using standardized meals under controlled conditions provide limited insight into real-world glycemic regulation.
What are the dietary, clinical, behavioral, and omics determinants of postprandial glycemic responses under free-living conditions?
Observational (n=8,700)

p-value: p=<0.05
Real-life postprandial glycemic responses are highly variable and significantly influenced by meal composition, clinical markers, and behavioral factors.

May inform dietary counseling in diabetes; extends controlled PPGR findings to free-living settings but leaves causal effects open.
Wu et al. (2026) reported an observational. Dietary, clinical, behavioral, and omics factors was evaluated on Postprandial glycemic responses (PPGRs) quantified through 20 different CGM metrics (p=<0.05). Real-life postprandial glycemic responses were significantly positively associated with meal total carbohydrate and clinical markers, and negatively associated with meal fat proportion (p<0.05).
