The Claim

In adults with obesity and abnormal glucose metabolism, retention rates during a 6-month dietary intervention were 83.2% in the personalized feedback group and 73.2% in the low-fat group, with no statistically significant difference between groups (P=0.21), indicating that personalized feedback does not substantially improve study adherence.

Description
1 study reviewed
In plain English

In a 6-month diet study with adults who have obesity and abnormal glucose metabolism, 83% of those receiving personalized feedback completed the program, compared to 73% of those on a low-fat diet; the difference in completion rates was not statistically significant.

See the scientific wording

In adults with obesity and abnormal glucose metabolism, the majority of participants (76%) completed a 6-month dietary intervention, with no significant difference in retention between personalized (83.2%) and low-fat (73.2%) groups (P=0.21), indicating that personalized feedback does not substantially improve study adherence.

Why this might work

People stick to a diet when their food choices give them immediate feedback about how their body responds, making them more likely to repeat actions that feel right and avoid ones that feel wrong, regardless of whether the advice is personalized or general.

    The study found that people who got personalized food feedback logged their meals more often than those who got standard advice, meaning they were more engaged. But the claim says both groups stuck with the program equally — which isn’t true based on the study’s actual data.
