Association between weight loss and health care resource utilization in adults living with obesity: Evidence from a UK primary care database
Authors' conclusion
Our findings suggest that intentional weight loss of 10-25% is associated with lower HCRU and costs in the long term among individuals living with obesity, relative to stable weight.
