GLP-1 Protein & Water Calculator

Appetite-shrunk protein targets, computed. Medical caveat: this is guidance math from published ranges, not medical advice — your prescriber's plan wins.

What the numbers mean

Published GLP-1 nutrition guidance converges on 1.2–1.6 g of protein per kg of body weight daily — the upper range matters if you're training or losing fast. Water: roughly 2–3 L/day for most adults, nudged up by activity. Protein first, everything second — when a meal is three bites, those bites carry your whole macro load.

Best foods for the job

Maximize protein per bite: the protein-per-calorie ranker sorts 6,190 foods. Highest density: chicken breast, egg whites, canned tuna, Greek yogurt, cottage cheese.

FAQ

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

Most published guidance lands at 1.2–1.6 g per kg of body weight per day — muscle loss is the main body-composition risk when appetite collapses. Use the calculator for your number and confirm with your prescriber.

Why is water harder on GLP-1s?

Appetite and thirst both drop. Dehydration is one of the most common side-effect amplifiers (constipation, dizziness, headaches). Aim for 2–3 L daily, more if active.

What if I can't hit the protein target?

Prioritize protein FIRST at each meal — the dex's protein-density ranker exists exactly for this: maximum protein per bite when every bite counts.
