GLP-1 Calorie Guidance (patient-friendly)

  • 🟢 Prioritize protein first to preserve lean mass and support fullness.
  • 🟢 Choose smaller, slower meals—stopping early can reduce nausea and reflux.
  • 🟢 Aim for fiber + hydration daily to help constipation and appetite control.
  • 🟢 If calories become very low due to appetite suppression, talk to your clinician about safe targets.
GLP-1 medications can change appetite and intake. Your best calorie target depends on your health history, labs, and treatment plan.

Insurance & Medical Safety Notes

  • 🟢 Insurance coverage for GLP-1 or bariatric surgery may require documented BMI, comorbidities, and prior authorization.
  • 🟢 Many plans require supervised weight-loss documentation and nutrition/psych evaluations for bariatric procedures.
  • 🟢 Coverage varies by plan and employer—final decisions are made by your insurer.
This calculator is for healthy adults. People under 18, over 65, pregnant or nursing, or with medical conditions should seek personalized guidance.

What you should know

  • 🟢 This calculator is for healthy adults and only estimates daily calorie needs.
  • 🟢 People who are under 18 or over 65 have different needs.
