GLP-1 appetite suppression makes protein intake the #1 nutrition struggle. Most users on Ozempic / Wegovy / Mounjaro / Zepbound need 0.7-1.0 g protein per lb body weight to preserve muscle during fat loss. Eating that much whole-food protein when your appetite is suppressed is genuinely difficult. Premium whey or plant protein powder adds 20-30 g per shake without adding volume — the lowest-friction way to hit protein targets on a GLP-1.

Frequently Asked Questions
How much protein do GLP-1 users need?
0.7-1.0 g per lb body weight. A 180 lb user targets 126-180 g/day. Most users eating less on GLP-1 get only 60-90 g from whole food — protein powder closes the gap.
Whey vs plant protein for GLP-1?
Whey absorbs faster (better for post-workout). Plant absorbs slower (steadier amino acid release). Both work for muscle preservation if dose is adequate. Whey is more cost-efficient per gram of protein.
Will protein powder cause nausea on a GLP-1?
Some users find shakes harder to tolerate than solid food in early titration weeks. Mix with milk + fruit for slower digestion, or try plant-based for users with whey sensitivity.
Best time to drink protein?
Morning (most users on GLP-1 have biggest appetite gap), pre/post workout, or before bed. Spread protein across 3-4 doses for optimal MPS (muscle protein synthesis).
Is grass-fed worth the premium?
For ingredient transparency and slightly better fatty acid profile: yes. For protein content alone: no — protein is protein regardless of source. Premium pricing pays for quality assurance.
Can I take it with my GLP-1 dose?
Yes — no interaction. Take protein with meals; GLP-1 dose timing is separate.
