Personalized nutrition improves gut microbiome diversity and richness in prediabetics compared to baseline, though the effect on body weight is inconsistent and dependent on study quality.
Personalized nutrition may improve gut health (microbiome diversity) in prediabetics. However, its effect on body weight is not consistent and may depend on the quality of the study or individual response.

Personalized nutrition also significantly reduced carbohydrate intake (–10.8% of energy, p = 0.02) compared to control diet. It also improved gut microbiome diversity and richness from baseline in prediabetics.
Why this rating
GRADE assessment indicates 'Low' or 'Very Low' certainty.
