A new study by U-M marketing professor Puneet Manchanda finds that combining human coaches with AI-powered weight-loss apps leads to significantly better outcomes. Analyzing data from 65,000 users of the HealthifyMe app, researchers discovered that participants who had both AI and human support lost 74% more weight over three months than those using AI alone. The findings could help health companies and policymakers develop more effective, personalized strategies to address obesity.
