Protein meal building tool
The protein calculator gives you a number for the day. This one is for a single meal. Filter the list, click to add, and see where you end up.
Protein on this plate
0 items on the plate · 0% of 30 g
Nothing on the plate yet. Pick something from the list to start adding it up.
Your plate
Your plate is empty. Add something from the list and it will appear here with a running total.
Frozen meals are worth checking
Everything under Whole meals is a single-serving package, so the number is the whole thing rather than a portion of it. They range more than the packaging suggests, from 11 g to 20 g across the five here, and a bowl sold on its protein can still come in under what one meal needs. Adding a yogurt or a stick of cheese alongside is usually what closes the gap.
Protein is not the whole plate
This tool only counts protein, because that is the part most people fall short on once appetite drops. Aim to put some vegetables and some carbohydrate on the plate as well. Include a little fiber rather than a lot: fiber helps with the constipation these medications can cause, but a large jump in it tends to make the bloating and fullness worse rather than better.
This is education, not medical advice
Protein targets have to be individualized, and a higher intake may be inappropriate if you have chronic kidney disease, liver disease, or are pregnant or breastfeeding. Talk to your prescriber or a registered dietitian before changing what you eat.
Where these numbers come from
Whole foods are calculated from USDA FoodData Central, which publishes protein per 100 grams, converted to the portion shown. Anything marked "label" is a real product named exactly as it is sold, with the grams taken from that manufacturer's own nutrition information. Several of them put the number in the product name, like the Chobani 20g drink and Core Power 42g, which makes it easy to check against the bottle in your hand. Every card links to the page the number came from, so you can open the label yourself rather than take this list on trust.
Brands do reformulate, and the light version of a product is usually a few grams lower than the regular one, so read your own panel if the number matters. Naming these products is not an endorsement, and there are good equivalents on every shelf.
Why it matters per meal, not just per day
Spreading it out builds more muscle
Mamerow and colleagues fed adults the same total protein two ways: about 30 g at each of three meals, or 11 g at breakfast, 16 g at lunch and 63 g at dinner. The even pattern produced 25% more muscle protein synthesis over 24 hours, on identical daily totals. It was a small crossover study, eight healthy adults over seven days, measuring the rate at which muscle is built rather than muscle actually gained, and it was not done in people on a GLP-1.
Most people skew it to dinner
That skewed arm was not an invented pattern. It is how protein intake is typically distributed, with a carbohydrate-heavy breakfast and most of the day's protein in the evening. Breakfast is usually where the easiest gain is.
A smaller appetite makes order matter
On a GLP-1 the stomach empties slowly and fullness arrives early, so what you eat first is often what you actually finish. Starting with the protein on the plate is a practical response to that, rather than a rule about food combining.
Protein alone does not do it
Eating the protein is half the job. Resistance training is the signal that tells the body to keep the muscle, and the guidance asks for muscle-strengthening work on two or more days a week alongside it.
A reasonable way to use this
Get your daily number from the protein calculator, divide it by the number of meals you actually eat, and put that in the target box. Then build one meal you would actually eat and see how it adds up. Most people find breakfast is the meal that comes up short, and that a single addition fixes it.

Knowing the number is the easy part
Hitting it every day, with the appetite you have now and the schedule you actually keep, is the part worth talking through with someone.
