SURMOUNT-1 Trial (Tirzepatide for Weight Loss in Adults with Obesity): Duration: 72 weeks (18 months) Participants: Adults with BMI 30+ or 27+ with comorbidities Intervention: Weekly tirzepatide injections + lifestyle counseling Average weight loss results in clinical trials of FDA-approved tirzepatide: Dose-dependent response: Higher doses produced greater weight loss Average range across doses: 15-22% of body weight over 72 weeks For context: A 230-pound person losing 20% would lose approximately 46 pounds Placebo (lifestyle alone): Approximately 3% of body weight Key findings: Weight loss was gradual, not rapid (took a full 72 weeks to reach maximum) Higher doses produced more weight loss (dose-response relationship) Almost everyone lost some weight, but the amount varied dramatically Lifestyle counseling was included (not medication alone) Individual Variation: Why Results Differ The clinical trial averages mask huge individual variation
