How much protein do you need on a GLP-1 medication?

Because GLP-1 medications reduce appetite, it's easy to under-eat protein — which risks muscle loss during weight loss. A common physician-supported target is roughly 0.7 to 1 gram of protein per pound of goal body weight per day, spread across meals. Prioritizing protein helps preserve lean muscle, supports metabolism, and improves body composition.

Why protein matters more on a GLP-1

When you eat less, your body can break down muscle along with fat unless protein and resistance activity are adequate. Muscle is metabolically active, so preserving it helps you keep your metabolic rate up and look toned rather than simply smaller.

Practical tips

Eat protein first at each meal, since fullness comes quickly. Use lean sources like chicken, fish, eggs, Greek yogurt, and legumes, and consider a protein shake if appetite is very low. GOAL.MD programs include nutrition coaching to help you hit these targets.
