Tirzepatide delivers some of the most substantial weight loss of any currently available medication.<\/p>\n

Clinical trial data<\/a> from the SURMOUNT-1 study shows that participants lost an average of 35 to 52 pounds over 72 weeks, depending on dose. On the highest dose (15 mg), average weight loss reached 22.5% of body weight, with over half of participants losing 20% or more.<\/p>\n

These results have made tirzepatide (sold as Mounjaro for diabetes and Zepbound for weight loss) one of the most sought-after weight loss treatments available. Here’s what the research shows about what you can realistically expect.<\/p>\n

The SURMOUNT-1 Trial Results<\/h2>\n

The landmark SURMOUNT-1 trial enrolled 2,539 adults with obesity or overweight and tracked their progress on tirzepatide for 72 weeks. Results varied by dose but were impressive across the board:<\/p>\n

The mean baseline weight was 231 pounds, so these percentages translate to meaningful, life-changing weight reductions for most participants.<\/p>\n

How Many People Achieve Different Milestones<\/h2>\n

Beyond averages, the distribution of results matters. Here’s what percentage of participants reached key weight loss thresholds at 72 weeks:<\/p>\n
