The useful shopping list here is built around three constraints: protein density, no cooking required, and things that keep. Buy less fresh food than you used to, because a list built around your old appetite produces waste. Everything below is chosen to be edible on a bad day.
For how this fits alongside the rest of eating and training on a GLP-1, see Eating and Training on a GLP-1: The Complete Guide.
Protein, the priority
Greek yoghurt, skyr, cottage cheese, quark. Cold, dense, no preparation, easy in small amounts.
Eggs, to boil in advance and keep ready in the fridge.
Tinned fish: tuna, salmon, sardines, mackerel. Long shelf life and useful when nothing else appeals.
Pre-cooked chicken, which removes the cooking step that is often the actual barrier.
Tofu and edamame, both of which work cold and suit people who have gone off meat.
Milk or kefir, for drinkable protein on days when chewing feels like work.
Protein powder or ready-made shakes, for the days solid food is impossible.
Plain and dry, for queasy days
Crackers, plain bread, oats, rice, plain potatoes. Unglamorous and often the only things that work.
These are low in protein, so pair them with something from the list above rather than making them the whole day.
Vegetables and fruit you will actually eat
Frozen vegetables, which keep indefinitely and need no preparation.
Pre-chopped or pre-washed produce, which removes the effort on days you have none.
Fruit that needs nothing done to it: bananas, berries, satsumas.
Buy smaller quantities of anything fresh. This is the single biggest source of waste when appetite has changed.
Fluids and the cupboard reserve
Oral rehydration sachets, bought before you need them. During vomiting or diarrhea they matter, and that is a poor moment to go to the shop.
Broths and soups, which count as fluid and are tolerable when food is not.
Herbal teas or squash if plain water is unappealing.
What to check on labels
Sugar alcohols in protein bars, shakes and low-sugar products. Erythritol, sorbitol, maltitol and similar are a frequent cause of bloating and diarrhea, and they catch people who have just added several servings a day for good reasons.
Protein per serving rather than per hundred grams, since what you can physically get down is the constraint.
Fat content on ready meals, since fat slows gastric emptying further.
Shopping habits worth changing
Do not shop on a bad day. Everything looks repellent and you will come home with nothing usable.
Shop after eating rather than before, for the same reason.
Buy for the week you will have, not the week you used to have. Smaller quantities, more often, produces less waste and less guilt.
Buy for the appetite you have now rather than the one you had. Keep oral rehydration sachets in before you need them, for the reasons in dehydration, and prepare on good days using meal prep.
Frequently asked questions
What should I always have in?
Something with protein that needs no preparation, and oral rehydration sachets.
Are protein bars worth buying?
Some are. Read the label for protein content and sugar alcohols.
How do I stop wasting food?
Buy smaller amounts of fresh food and rely more on frozen and tinned.
What if I have gone off meat?
Dairy, eggs, fish, tofu and legumes cover it. Rotate them.
Do I need special GLP-1 products?
No. Ordinary food chosen for protein density and ease works.
Should I buy meal replacement shakes?
Useful as a bridge on bad days. Worth discussing with a dietitian if they become most of your intake.
