Why protein is priority #1
- Protects muscle during rapid weight loss (some loss is lean mass).
- Keeps you full — the most satiating macronutrient.
- Supports metabolism and recovery.
- Low in fat when you choose lean sources — gentle on the stomach.

Animal vs. plant protein
Animal proteins (poultry, fish, eggs, dairy) are “complete” and very efficient per calorie. Plant proteins (beans, lentils, tofu, edamame) also bring fiber, which helps with fullness and regularity. A mix of both works well; vegetarians should combine sources and may lean on tofu, edamame, Greek yogurt and protein powder to reach their target.

Frequently asked questions
How much protein do I need on GLP-1?
Many people aim for roughly 0.6–0.8 grams per pound of body weight (higher during active weight loss to preserve muscle). Use the protein calculator for a personalized number.
What are the best protein foods?
Chicken, turkey, fish, eggs, Greek yogurt, cottage cheese, tofu, beans, lentils and protein shakes are efficient, GLP-1 friendly sources.
Why is protein so important on these medications?
Rapid weight loss can include muscle. Adequate protein plus some resistance activity helps preserve lean mass and keeps you full.
Can I get enough protein as a vegetarian?
Yes — combine tofu, edamame, beans, lentils, Greek yogurt, eggs (if you eat them) and protein powder. Plant proteins add helpful fiber too.
