Examining the effectiveness of a new digital care model on weight loss for people living with obesity

This real-world evaluation of more than 2,600 patients in Sweden showed that Yazen’s comprehensive digital obesity care model achieved 12.6% weight loss after 6 months, alongside significant improvements in cardiometabolic health markers.
