The Claim
Among adults aged 41–70 with high adherence to a personalized nutrition program, HbA1c levels decreased by 0.06% and waist circumference decreased by 6.31 cm compared to those with low adherence.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Adults aged 41–70 who closely followed a personalized nutrition plan had lower HbA1c levels and smaller waist circumferences than those who did not follow the plan closely.
See the scientific wording
Among highly adherent adults aged 41–70, a personalized nutrition program resulted in greater reductions in HbA1c (−0.06%) and waist circumference (−6.31 cm) compared to low-adherence participants, suggesting that adherence to personalized dietary guidance is a critical determinant of metabolic benefit.
When people eat foods tailored to their unique metabolism and gut bacteria, their gut bacteria change to types that produce beneficial chemicals. These changes make them feel fuller longer, so they eat fewer calories without trying. The body then burns stored fat, shrinking waist size, and reduces inflammation that interferes with blood sugar control, leading to lower HbA1c.
What the research says
1 studyStudy: Effects of a personalized nutrition program on cardiometabolic health: a randomized controlled trial
People who stuck closely to their custom diet plan lost more waist size and lowered their blood sugar a bit more than those who didn’t follow it as well — showing that following the plan matters for getting healthier.
