TL;DR
-
Most people on a GLP-1 benefit from 1.2-2.0 grams of protein per kilogram of body weight daily.
-
Prioritizing protein helps preserve lean muscle during weight loss.
-
Appetite suppression makes protein timing and quality even more important,
Most research suggests aiming for 1.2-2.0 grams of protein per kilogram of your body weight per day while taking a GLP-1.
For example, if your weight is 150 pounds, that’s roughly 82-136 grams of protein daily. At 180 pounds, that range becomes 98-164. If that feels high, remember that the goal is fat loss while preserving lean muscle.
GLP-1 medications reduce appetite. But eating less overall means you’re also at a higher risk of under-eating protein, and that can cost you muscle.
Protein has many benefits, like supporting metabolism, muscle growth, recovery, and blood sugar stability. The challenge is that you may not feel hungry enough to eat large portions. That’s where quality really matters. Your body recognizes and absorbs real food protein more efficiently than ultra-processed powders packed with additives.
Using a minimally processed protein supplement, like beef protein isolate , can help you reach your protein goals while taking a GLP-1.
Key Takeaways
-
Protein needs are higher on GLP-1 medications. Aim for 1.2–2.0g of protein per kilogram of body weight daily to preserve lean muscle while losing fat.
-
GLP-1s suppress hunger, making it easy to under-eat protein, which can lead to muscle loss if not actively managed.
-
Since portions are smaller, choosing minimally processed, easily absorbed sources like beef protein isolate helps you hit your goals without relying on additive-heavy powders.
