How much protein do you need on Mounjaro or Wegovy?
On weight-loss medication, protein is the number that keeps your muscle while the fat comes off. Most people aren't eating enough of it.
How this is calculated
Your target is based on your body weight and activity level, using the protein ranges sports-nutrition research recommends for preserving lean mass in a calorie deficit — roughly 1.6–2.2g of protein per kg of body weight.
If you're on a GLP-1 medication like Mounjaro, Wegovy, Ozempic or Zepbound, we nudge the target a little higher. These drugs suppress appetite hard, so muscle loss is a real risk — and protein is the single biggest lever to protect it while you lose fat.
This is an estimate to aim for, not medical advice. If you have kidney conditions or other health concerns, talk to your doctor about the right intake for you.
