The Claim

Continued tirzepatide treatment significantly reduces waist circumference and improves cardiometabolic risk factors, including hemoglobin A1c, fasting glucose, insulin, lipid profile, and blood pressure, compared to placebo in adults with obesity or overweight without diabetes over 52 weeks of double-blind treatment.

In plain English

Tirzepatide treatment reduces belly fat and improves blood sugar, insulin, cholesterol, and blood pressure in overweight or obese adults without diabetes over 52 weeks, compared to placebo.

See the scientific wording

Continued tirzepatide treatment significantly reduces waist circumference and improves cardiometabolic risk factors (hemoglobin A1c, fasting glucose, insulin, lipid profile, and blood pressure) compared to placebo in adults with obesity or overweight without diabetes over 52 weeks of double-blind treatment.

Why this might work

Tirzepatide binds to and activates two hormone receptors in the brain and body: GIP and GLP-1 receptors. This activation tells the brain to reduce appetite and eat less, while also improving how the body uses sugar and burns energy. The result is steady weight loss, especially from the belly, and better blood sugar, cholesterol, and blood pressure.

1 study

  1. Study: Continued Treatment With Tirzepatide for Maintenance of Weight Reduction in Adults With Obesity: The SURMOUNT-4 Randomized Clinical Trial.

    The study showed that people who kept taking tirzepatide lost more weight and kept it off, while those who stopped regained weight. Since losing weight usually improves blood sugar, cholesterol, and blood pressure, this supports the idea that staying on the drug helps those numbers too.
