GLP-1 receptor agonists (semaglutide, tirzepatide) and bariatric surgery produce substantial weight loss (>10-15%) and improve cardiometabolic risk factors, but weight regain is common upon discontinuation, often necessitating lifelong treatment.

GLP-1 medications and surgery are currently the most effective tools for significant weight loss and metabolic improvement. However, they are not 'cures'; stopping them typically leads to weight regain. If you choose this path, prepare for it to be a long-term or lifelong commitment, and verify insurance coverage or affordability before starting.
