Adherence
Inclusion of genetic risk information in personalized nutrition advice does not significantly improve dietary changes, lifestyle behaviors, or weight loss outcomes compared to generic advice.
Do not pay for expensive genetic testing to guide your diet. Large studies show that knowing your genetic risk for obesity or diabetes does not help you lose weight or eat better than standard healthy eating advice. Focus on proven behavioral strategies like tracking intake and physical activity instead.
GoodRefutesHIGH confidence
Based on the HEI and other parameters reflecting a healthy diet, personalization was superior to generic advice but inclusion of blood markers and genetic risks in the communication delivered no significant beneficial effects.
Why this rating
Based on large-scale RCTs (Food4me, 1600 participants) and systematic reviews of RCTs.
