Hormonal

Tirzepatide, a dual GLP-1 and GIP receptor agonist, produces significant weight loss (17.8% placebo-subtracted) in individuals with obesity without diabetes.

Tirzepatide is a once-weekly injection that significantly reduces body weight in people with obesity, even without diabetes. It works by mimicking two gut hormones (GLP-1 and GIP) to reduce appetite and improve metabolism. While effective, it can cause temporary gastrointestinal issues like nausea, which usually subside as your body adjusts.
