GLP-1 Weight Loss Tracker

Track your progress or plan your weight loss journey with semaglutide (Ozempic/Wegovy) or tirzepatide (Mounjaro)

Ozempic

Ozempic (semaglutide) is a GLP-1 receptor agonist medication. These kind of medications mimic a natural hormone, regulating appetite and blood sugar. It reduces hunger, slows stomach emptying, and helps you feel full longer, leading to reduced calorie intake and hence weight loss. The nature of the weight loss is most dramatic in the first few months and gradually plateau over time.

Frequently Asked Questions

These projections are based on large clinical trials with thousands of participants. However, individual results vary significantly. The calculator provides statistical averages - some people lose more, some lose less. Factors like diet, exercise, medication dose, and individual metabolism all play important roles.

Weight loss naturally slows as your body adapts. As you lose weight, your metabolism decreases slightly, and your body becomes more efficient with calories. This is normal and expected. Most GLP-1 medications show maximum weight loss around 9-12 months, after which weight stabilizes if the medication is continued.

Most people regain some or all of the weight lost when they stop GLP-1 medications, as appetite and hunger signals return. These medications are typically intended for long-term use. Maintaining weight loss after stopping requires significant lifestyle changes including diet modification and regular exercise.

Tirzepatide (Mounjaro) generally shows superior weight loss results compared to semaglutide (Ozempic/Wegovy). Clinical trials showed 21% average weight loss with tirzepatide vs 15% with semaglutide. However, individual responses vary, and some people respond better to one medication over the other. Cost, insurance coverage, and side effect profiles also differ.

While the medication provides a baseline effect, you can optimize results through lifestyle factors. Focus on high-protein meals (which maximize the medication's satiety effects), resistance training (to preserve muscle mass), adequate sleep (7-9 hours), stress management, and staying well-hydrated. Avoid ultra-processed foods and excessive alcohol.

If you're losing weight slower than the calculator predicts, discuss with your healthcare provider. They may need to adjust your dose, check for underlying conditions affecting metabolism, or help you identify diet and lifestyle factors that could be optimized. Some people are "slow responders" and may benefit from dose adjustments or medication changes.

While the medication reduces appetite and helps you eat less naturally, combining it with intentional diet and exercise produces better results. You don't need to follow an extreme diet, but making healthier food choices and adding moderate physical activity (even just walking) can significantly enhance outcomes and help maintain muscle mass during weight loss.

This calculator is based on adult clinical trials and is intended for adults only. While some GLP-1 medications are approved for adolescents age 12+, weight loss patterns may differ in younger individuals. Consult a pediatric specialist for guidance on weight management in children and teens.
