Summary

This study tests a digital platform called HMZ 2.0 that helps pregnant women with overweight or obesity manage their weight gain. 144 women will be randomly assigned to use the platform or receive standard pregnancy advice. The platform tracks weight, activity, and eating, and offers personalized coaching from a dietitian. The goal is to see if this approach can help women stay within healthy weight gain guidelines and improve outcomes for both mother and baby.
