Everyday High-Protein Foods for GLP-1 Users

The hardest part of eating well on a GLP-1 medication is not knowing that protein matters. It is hitting a protein target on an appetite that has genuinely halved, on a day when the thought of chicken is unbearable.

This page is organised around that reality โ€” not by food group, but by the situation you are actually in when you open the fridge. If you do not yet know your daily target, start with the protein calculator; if you want the reasoning behind the numbers, that is in the nutrition guide.

๐ŸŽฏ The practical target

Most adults losing weight on a GLP-1 are aiming for roughly 1.2โ€“1.6 g of protein per kg of ideal body weight โ€” commonly somewhere between 80 g and 130 g a day. Broken into four servings of 20โ€“30 g, that is far less daunting than one number.

When nothing sounds good

This is the situation that derails protein intake more than any other, and it is usually worst in the days right after a dose or a titration step. Liquid and cold options work when solid food does not โ€” they carry no cooking smell, need no preparation, and go down when a plate will not.

No-cook and minimal effort

Reduced appetite tends to reduce willingness to cook along with it. Keeping these on hand means a protein serving is never more than a minute away:

Shelf-stable staples worth keeping in the cupboard

The strategic move is to stock the non-perishable options *before* a bad stretch, because that is precisely when you will not feel like shopping.

Fresh foods worth buying weekly

These come from a grocery store rather than a delivery box, but they carry the most protein per serving:

FoodServingProteinWhy it suits a small appetite
Chicken breast4 oz35 gHighest protein per volume; easy to digest
Salmon4 oz25 gOmega-3s; richer, so easier on nausea days than red meat
Greek yogurt1 cup20 gCold and mild; no preparation
Shrimp4 oz24 gCooks in minutes; very light
Cottage cheese1/2 cup14 gSlow-digesting; good last thing at night
Eggs2 large12 gCheap, versatile, tolerated by most
Firm tofu4 oz10 gPlant-based; takes on other flavours when meat is off-putting
Lentils1 cup cooked18 gPlant-based; high fibre, which helps with constipation

Protein values are approximate and vary by brand, cut and preparation. Check the label on what you buy.

Products you can order

Fresh food is a grocery trip, but the shelf-stable protein that gets you through a bad week can simply be delivered. These are the options we point people to most often โ€” the links below are affiliate links, as disclosed above.

๐Ÿฅค A note on shakes and bars

Whole food is generally the better default โ€” it brings fibre and micronutrients a shake does not. But the best protein source is the one you will actually consume today. On a day when solid food is impossible, a shake is not a compromise; it is the thing standing between you and losing muscle.

Putting it together: hitting 100 g

Three ways the same target can be reached, depending on the kind of day you are having:

The point of the third row is that even a day when you cannot face food is a day you can hit your target. Plan for that day before it arrives.
