GLP-1 receptor agonists (glucagon-like peptide-1) are a class of medications originally developed for type 2 diabetes that have shown remarkable effectiveness for weight management. These medications work by mimicking the GLP-1 hormone, which helps regulate blood sugar, slow gastric emptying, and reduce appetite.
Popular GLP-1 medications include Ozempic (semaglutide), Mounjaro (tirzepatide), Zepbound (tirzepatide for weight loss), and Wegovy (semaglutide for weight loss). Clinical trials have shown average weight loss of ~15% with Ozempic, ~22% with Mounjaro, and ~20% with Zepbound.
While these medications are highly effective, users need to pay special attention to nutrition — especially protein intake — hydration, and regular monitoring. Our free GLP-1 calculator tools are designed to help you navigate these important aspects of your journey.
Why GLP-1 Users Need These Tools
GLP-1 medications are powerful — but they come with unique nutritional and financial considerations that most users aren't prepared for.
Prevent Muscle Loss
GLP-1 medications reduce appetite significantly, which can lead to inadequate protein intake. Research shows users on semaglutide or tirzepatide need 1.2–1.6 g of protein per kg of body weight daily to preserve lean muscle mass. Without tracking, most users fall short. Our GLP-1 Protein Calculator gives you a personalized daily target in seconds.
Set Realistic Weight Loss Expectations
Clinical trial averages — 15% on Ozempic (STEP-1) and 22.5% on Mounjaro (SURMOUNT-1) — represent population means. Your actual results depend on starting weight, dosage, diet, and adherence. Our Ozempic Weight Loss Calculator models your personal trajectory month by month, helping you set achievable milestones.
Navigate the True Cost
Without insurance, Ozempic runs ~$900/month and Mounjaro ~$1,050/month. But compounded semaglutide can cost as little as $150–$300/month, and manufacturer savings cards can bring brand-name costs down to $25–$75 for insured patients. Our GLP-1 Cost Calculator compares every option side by side so you can make an informed financial decision.
Choose the Right Medication
Ozempic, Wegovy, Mounjaro, and Zepbound are not interchangeable. They differ in FDA-approved indications, mechanism of action, dosing schedules, average weight loss, and cost. Our GLP-1 Drug Comparison lays everything out in a single table so you can have a more informed conversation with your healthcare provider.
