Protein Targets on GLP-1: How Much Do You Actually Need?
With appetite suppressed to a fraction of normal, hitting protein targets is one of the hardest and most important things you can do on GLP-1 medications.
When your appetite drops to a fraction of its former level, calories become scarce — and protein, which requires conscious prioritization even at normal appetite, becomes very difficult to hit. But protein may be the single most important nutritional variable to optimize on a GLP-1.
Why Protein Is Different
Unlike carbohydrates and fat, protein cannot be stored. Every day you fall short of your protein target, your body compensates by breaking down muscle tissue to meet its amino acid needs. Over months on a GLP-1, this deficit compounds into meaningful lean mass loss.
The Targets
Current evidence supports 1.2–1.6g of protein per kilogram of body weight per day for people undergoing significant caloric restriction. Some protocols push toward 2.0g/kg to maximize muscle preservation. For a 75kg person, that means 90–150g of protein daily — from a total intake that may only be 1,000–1,400 calories.
Practical Strategies
Protein-first eating (building every meal around a protein source before adding other macros), protein shakes as a supplement rather than a meal replacement, Greek yogurt, cottage cheese, eggs, and lean meats provide the highest protein density per calorie. Tracking via an app for at least the first few weeks is strongly recommended to calibrate intake.
