What to actually eat every day when your appetite has halved
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.
Most adults losing weight on a GLP-1 are aiming for roughly 1.2โ1.6 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 20โ30 g, that is far less daunting than one number.
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.
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:
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.
These come from a grocery store rather than a delivery box, but they carry the most protein per serving:
| Food | Serving | Protein | Why it suits a small appetite |
|---|---|---|---|
| Chicken breast | 4 oz | 35 g | Highest protein per volume; easy to digest |
| Salmon | 4 oz | 25 g | Omega-3s; richer, so easier on nausea days than red meat |
| Greek yogurt | 1 cup | 20 g | Cold and mild; no preparation |
| Shrimp | 4 oz | 24 g | Cooks in minutes; very light |
| Cottage cheese | 1/2 cup | 14 g | Slow-digesting; good last thing at night |
| Eggs | 2 large | 12 g | Cheap, versatile, tolerated by most |
| Firm tofu | 4 oz | 10 g | Plant-based; takes on other flavours when meat is off-putting |
| Lentils | 1 cup cooked | 18 g | Plant-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.
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.
| Product | Serving | Protein | Best for | Where |
|---|---|---|---|---|
| Whey protein powder | 1 scoop | 25 g | Most protein per unit of volume and cost; mix to whatever strength you can manage | View on Amazon โ |
| Fairlife Core Power | 14 oz bottle | 26 g | Ready to drink, no mixing โ the reliable option on a nausea day | View on Amazon โ |
| Premier Protein shakes | 11.5 oz bottle | 30 g | Highest protein per bottle here; useful when one serving has to do a lot of work | View on Amazon โ |
| Quest protein bars | 1 bar | 20 g | Portable and shelf-stable; keep in a bag or desk for the day that gets away from you | View on Amazon โ |
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.
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.
The calculator turns your weight, activity level and medication into a single daily protein number โ then come back here for what to eat to reach it.
