What I Actually Bought at Costco
I photographed this grocery run because these are examples of foods I actually purchased, not a theoretical warehouse list. What I buy changes from trip to trip, but I tend to look for convenient protein, produce, freezer options and a few shortcuts that can turn into quick meals.
Two of these purchases now show up in meals on the site: the Easy Protein Bowl and my Sweet Kale Salad + Chicken Shawarma.

Quick answer
A useful GLP-1 Costco grocery list focuses on easy protein, gentle carbs, simple freezer staples, drinks you can sip, and foods that can be portioned into smaller meals. Availability varies by warehouse, and product labels can change, so check the package before buying.

High-protein Costco foods
- Low-fat or nonfat Greek yogurt cups or tubs.
- Cottage cheese, especially lower-fat options if rich dairy feels heavy.
- Eggs or egg whites for simple breakfasts.
- Rotisserie chicken with skin removed or lean prepared chicken.
- Salmon, tuna packets, canned tuna in water, or frozen fish portions.
- Low-sugar protein shakes for low-appetite days.
Gentle carbs and easy sides
Keep a few bland or simple starches available. Rice, baked or microwave potatoes, oatmeal, whole-grain crackers, soup, and broth can be helpful when a full meal does not sound good.
Fruits, vegetables, and freezer staples
Frozen berries, bananas, apples, pears, green beans, carrots, spinach, and simple vegetable blends can be easier to use before they spoil. If raw vegetables feel hard to tolerate, try cooked or softer textures.
Hydration and easy drinks
Water, mineral water, low-sugar electrolyte drinks, broth, tea, and protein shakes can all fit different needs. Carbonated drinks may add bloating for some people, and high-sugar drinks may not feel good during nausea or reflux.
Easy GLP-1 meal ideas from Costco
| Meal idea | Simple cart items | How to keep it easier |
|---|---|---|
| Chicken soup bowl | Rotisserie chicken, broth, frozen vegetables, rice | Remove skin, keep broth-based, and start with a smaller bowl. |
| Yogurt protein breakfast | Greek yogurt, berries, oatmeal or crackers | Choose lower-fat yogurt if full-fat dairy feels heavy. |
| Salmon and potato plate | Salmon fillets, potatoes, green beans | Bake or air-fry with a small amount of oil and avoid heavy sauces. |
| Tuna snack plate | Tuna in water, crackers, cucumber or fruit | Use a small portion and go easy on mayo or creamy dips. |
Costco foods to be careful with
Some popular warehouse foods are rich, oversized, fried, creamy, or very high in sugar. Pizza, large bakery desserts, creamy dips, fried appetizers, heavy frozen meals, greasy sandwiches, and large restaurant-style portions may be harder to tolerate, especially during dose changes or low-appetite days.
If you want a store-agnostic version of this list to take shopping anywhere, the free GLP-1 Grocery List covers the same categories in a printable format.

You do not need to treat the food court or bakery as forbidden. Large bakery items and food-court meals are often rich or oversized, so splitting an item, choosing a smaller portion, or saving part for later may feel easier for some people.
Food court and bakery portion considerations
Bulk shopping can create waste when appetite is unpredictable. Individually frozen foods, single-serve yogurt or shakes, shelf-stable pantry items, and foods that can be portioned and frozen may be more practical than large perishable packages.
Bulk buying when appetite is smaller
Availability varies by warehouse, but useful categories often include rotisserie chicken, lean poultry, tuna packets, salmon, eggs, egg whites, Greek yogurt, cottage cheese, lower-sugar protein shakes, oatmeal, microwave rice or potatoes, frozen vegetables, frozen fruit, broth, crackers, and unsweetened applesauce.
