Tirzepatide—known by the brand names Mounjaro (for diabetes) and Zepbound (for weight loss)—is a highly effective medication that helps regulate appetite, fullness, digestion, and blood sugar. It works by targeting two natural hormone pathways in the body (GLP-1 and GIP receptors), making it particularly powerful for weight management and metabolic support.

Tirzepatide works in several ways:

• Decreases appetite and cravings: It helps signal to your brain that you’re full, allowing you to feel satisfied with smaller portions and reducing the urge to snack.
• Slows stomach emptying: Food stays in your stomach longer, which increases fullness and helps control overeating.
• Stabilizes blood sugar levels: It reduces blood sugar spikes after meals and improves insulin sensitivity, which can further reduce cravings—especially for high-carb or sugary foods.
• Dual-hormone action: Because it works on both GLP-1 and GIP pathways, tirzepatide can result in even greater weight loss than medications that work on GLP-1 alone.
• Supports long-term weight reduction: By influencing appetite and metabolic signals, tirzepatide helps lower the body’s “set point,” making sustained weight loss more achievable with lifestyle changes.

Both Mounjaro and Zepbound contain the same active ingredient (tirzepatide), but they are approved for different purposes depending on dose and treatment goals.
