GLP-1 Weight Loss Calculator (Australia)
Calculate expected weight loss with GLP-1 medications (Mounjaro, Wegovy, Zepbound, Ozempic). Accurate medical estimator based on clinical trial data.
Expected Weight Loss with GLP-1 Medications
GLP-1 receptor agonists (such as semaglutide and tirzepatide) are modern medications used to treat Type 2 diabetes and obesity. They work by mimicking gut hormones that slow stomach emptying, suppress appetite, and improve insulin sensitivity.
Clinical trial data indicates that patients can lose between 10% and 20% of their starting body weight over a 68-to-72 week period when combined with healthy lifestyle, nutrition, and exercise modifications.
This calculator provides weight loss projections based on clinical trials (like STEP and SURMOUNT). Sustaining this progress requires permanent adjustments to diet, prioritizing protein intake, and performing resistance training to protect muscle mass.
Frequently Asked Questions
Q: How much weight can you lose on GLP-1 meds?
Clinical studies show an average loss of 15% to 20% of starting body weight over 12-18 months of continuous therapy.
Q: What happens when you stop GLP-1 medications?
Research indicates that many patients regain a significant portion of the lost weight if the medication is stopped without permanent dietary and lifestyle habits in place.
