Free GLP-1 tool
GLP-1 Protein Planning Tool
Organize protein around a target you already have — or see why published ranges disagree. This is not a prescription calculator.
What this result means
Divide a clinician-provided protein target, or explore published ranges, without turning the page into a protein prescription.
Pathway A only divides a daily gram target the user already received. Pathway B displays cited published ranges (IOM RDA 0.8 g/kg; energy-restriction review 1.2–1.6 g/kg; ISSN exercise 1.4–2.0 g/kg) without selecting one. Pathway C applies those same ranges only to a user-entered actual body weight. Measured lean mass fails closed because the cited formulas are per kilogram of body weight and no separately sourced lean-mass formula is encoded. Food examples are approximate USDA reference amounts. The tool never invents ideal body weight or a medical protein prescription.
What this tool cannot tell you
- What protein target you should eat.
- Whether to use actual, ideal, adjusted, or lean-mass weight.
- Whether a published range is safe if you have kidney disease, pregnancy, frailty, or another medical limit.

Encoded only the adult Recommended Dietary Allowance of 0.8 g protein per kg body weight per day. This is a general adequacy number, not a GLP-1 or weight-loss prescription.

American Journal of Clinical Nutrition · 2015-04-29 · Last verified 2026-09-16
Cited for the commonly discussed higher-protein range during energy restriction (about 1.2–1.6 g/kg). Encoded as a published discussion range, not as an individualized target.
- International Society of Sports Nutrition Position Stand: protein and exercise
Journal of the International Society of Sports Nutrition · 2017-06-20 · Last verified 2026-09-16
Encoded the ISSN exercising-individual range of 1.4–2.0 g/kg/day. This applies to people who train; it is not a universal medical protein prescription.
- USDA FoodData Central
U.S. Department of Agriculture · Last verified 2026-09-16
Approximate educational food-protein examples only. Values are typical reference amounts, not a meal prescription and not a substitute for a food label.
