Personalized nutrition significantly reduces carbohydrate intake compared to control diets, with a median mean difference of -10.8% of energy.
Personalized nutrition interventions in this review led to a significant reduction in carbohydrate intake (averaging 10.8% less energy from carbs) compared to standard diets. This suggests that personalized approaches may naturally guide patients toward lower-carb profiles that benefit their specific metabolic health.
Personalized nutrition also significantly reduced carbohydrate intake (–10.8% of energy, p = 0.02) compared to control diet.
Why this rating
GRADE assessment indicates 'Very Low' certainty due to risk of bias, heterogeneity, and small sample size.
