About Titration

GLP-1 medications are started at a low dose and increased gradually every 4 weeks to minimize side effects like nausea. Your doctor may adjust this schedule based on your tolerance.

Always follow your prescriber's instructions. Do not change your dose without medical guidance.
⚕️BMI is a general screening tool and does not account for muscle mass, bone density, or other factors. It is not a diagnostic measure. Speak to your healthcare provider for a complete health assessment.
The GLP-1 BMI Calculator shows your current Body Mass Index and projects what your BMI will be once you reach your goal weight. A color-coded scale shows which BMI category you are in today and where you'll land after losing weight on a GLP-1 medication.

BMI Before & After

See how your BMI changes as you lose weight.

Your Measurements

⚕️Calorie estimates are calculated using the Mifflin-St Jeor formula and are approximations only. Individual metabolism varies. Do not use this tool to create extreme calorie deficits without medical supervision.
The GLP-1 Calorie Deficit Estimator calculates your Total Daily Energy Expenditure (TDEE) using the Mifflin-St Jeor formula, then models how GLP-1 appetite suppression creates a calorie deficit. A 12-week projected weight loss table shows your expected results week by week.

Calorie Deficit Estimator

GLP-1 medications reduce appetite — here's how that translates to calorie deficits and weight loss.
