Why this matters: Both surgical and medication-based weight loss are most effective when combined with proper nutrition and regular exercise. Your answers help us show you more realistic, personalized estimates — not just best-case clinical trial numbers.
📊 Weight Loss & Regain Estimates:
Surgical weight loss estimates are based on published clinical research including multicenter trials, systematic reviews and meta-analyses,
and long-term outcome studies (1–10 years post-procedure). Key references include data from the American Society for Metabolic
and Bariatric Surgery (ASMBS), peer-reviewed journals including Surgery for Obesity and Related Diseases (SOARD), Obesity Surgery,
and JAMA Surgery, and large-scale registry data from the Metabolic and Bariatric Surgery Accreditation and Quality Improvement
Program (MBSAQIP). Long-term surgical regain data draws from the Swedish Obese Subjects (SOS) study and the LABS cohort.
GLP-1 medication weight loss estimates are based on controlled clinical trials (STEP 1–5, OASIS 1, SURMOUNT-1–5) showing 14–21% total body weight loss over 64–72 weeks with FDA-approved formulations. Real-world adherence and results are typically lower. Weight regain projections after stopping are based on the STEP 1 Extension Study (Wilding et al., NEJM 2022) and SURMOUNT-4 (Aronne et al., JAMA 2024), which documented an average of 65% regain of lost weight within 12 months of discontinuation. Ongoing regain while continuing medication is derived from real-world observational data.
Individual results will vary significantly based on age, medical history, adherence to treatment protocols, lifestyle changes, and individual metabolism.
