Why protein matters on GLP-1 medications
- Prevents muscle loss: rapid weight loss can include lean mass; protein plus activity protects it.
- Satiety: protein is the most filling macronutrient, complementing the medication’s appetite reduction.
- Recovery & metabolism: adequate protein supports muscle maintenance and daily function.
How this calculator works
It estimates a daily target of roughly 1.4–1.8 grams of protein per kilogram of body weight, weighted toward the higher end during active weight loss on a GLP-1 medication to help preserve muscle. It then splits the target across about four meals and snacks. This is a general estimate — your clinician or a registered dietitian can personalize it, especially if you have kidney disease.
Best protein foods to hit your target
See our high-protein foods list and protein snacks. A protein shake is an easy way to close the gap on low-appetite days.
Next: your fiber target
Fiber helps prevent the constipation common on GLP-1 meds.
Frequently asked questions
How much protein should I eat on Ozempic?
Many people aim for about 0.6–0.8 grams per pound of body weight per day, toward the higher end during active weight loss to preserve muscle. The calculator gives you a personalized number and per-meal split.
Why do I need more protein on GLP-1 medications?
Because rapid weight loss can include muscle. Higher protein intake, combined with some resistance activity, helps protect lean mass and keeps you full.
Can I get too much protein?
For most healthy people, the amounts here are safe. If you have kidney disease or other conditions, ask your clinician about your target before increasing protein.
How do I split protein across the day?
Spreading protein across 3–4 meals and snacks (roughly 20–35 g each) is more effective for muscle maintenance than one large serving.
