Why protein matters most on a GLP-1

When appetite drops, total food intake falls and protein is usually the first thing to come up short. That's a problem, because rapid weight loss always includes some muscle — and protein, paired with resistance training, is what blunts that. Protecting muscle keeps you stronger and supports long-term maintenance.

How to actually hit your target

Eat protein first at each meal, since you'll fill up fast. Lean on easy, soft sources — Greek yogurt, eggs, fish, tofu, legumes, and shakes on low-appetite days. Our protein targets guide has a full food list, and what to eat on a GLP-1 covers the bigger nutrition picture.

Frequently asked questions

How much protein should I eat on a GLP-1?

Roughly 0.6–1.0 g per pound of goal weight — often about 80–120 g a day. Individualize with a clinician or dietitian, especially with kidney disease.

Why is protein so important on a GLP-1?

Rapid weight loss includes some muscle loss. Protein plus resistance training is the best-supported way to protect muscle while losing fat — which also helps maintenance.
