GLP-1 calculators

Simple, private calculators that give general estimates. Nothing you enter leaves your browser.

Protein calculatorEstimate a daily protein range while on a GLP-1 medication, based on body weight and activity. General guidance only — check with your dietitian.
BMI calculatorWork out your body mass index (BMI) in metric or imperial units and see the standard NHS and WHO adult categories. A screening number, not a diagnosis.
BMR & TDEE calculatorEstimate your basal metabolic rate (BMR) and total daily energy expenditure (TDEE) with the Mifflin-St Jeor equation. Useful context on a GLP-1 journey.
Calorie calculatorEstimate maintenance calories and a gentle deficit range from your TDEE. General estimates only — appetite on GLP-1 medication varies, so eat to need.
