Top 10 Costco Protein Picks for Your GLP-1 Journey
You saw PJ's Costco Cart reel fly by — here's the full breakdown. The ten items, protein versus calories for each, and why every one earns its spot when you're eating with a GLP-1-sized appetite.
If you caught PJ's Costco Cart reel, you already watched the highlight version fly by. Here's the full breakdown you asked for: the ten items, what each one actually brings in protein versus calories, and why it earns a spot in the cart when you're eating with a GLP-1-sized appetite.
One honest note before the list
The numbers below are approximate — pulled from product listings and nutrition databases, not a lab. The label on the package is always the final word, so give it a glance when you're standing in the aisle. And none of this is medical or nutrition advice: how much protein is right for you is a conversation for you and your provider, not a blog post.
The 10 picks
1. Kirkland Rotisserie Chicken
The cart MVP. About 19g of protein in a 3 oz serving for roughly 140 calories, already cooked, and cheap enough that you'll actually keep buying it. Pull the meat the day you get home and lunches are sorted for the week. Costco page
2. Kirkland Organic Greek Yogurt (48 oz)
Around 17g of protein in a ¾-cup serving at about 100 calories, and the big tub is far better value than single-serve cups. Perfect for the mornings when a full meal feels like too much — which, on a GLP-1, is a lot of mornings. Costco page
3. Kirkland Cottage Cheese (community pick · in-warehouse)
One of the two items you kept asking us to add. Roughly 13g of protein per half cup (about 100 calories), so a full cup lands near 25g. Savory or sweet, it's an easy protein hit for when yogurt starts to feel repetitive.
4. Kirkland Free-Range Eggs (24 ct)
6g of protein and 70 calories each, endlessly flexible, and the 24-count means you're not back at the store in three days. Hard-boil a batch and you've got the simplest grab-and-go protein there is. Costco page
5. Kirkland Wild Sockeye Salmon
About 18g of protein in a 3 oz portion for around 145 calories, plus omega-3s. The individually wrapped fillets let you cook one without defrosting a whole side of fish. Costco page
6. Fairlife Protein Shakes (community pick)
The other most-requested addition. The Nutrition Plan bottles bring about 30g of protein for roughly 150 calories (the Core Power line runs a little higher, around 26g and 170). For the days when chewing a whole meal just isn't happening, a cold shake covers the protein floor. Costco page
7. Kirkland Whole Grain Rolled Oats (10 lb)
Not a protein hero on its own — about 5g per half-cup dry — but 4g of fiber for 150 calories, and fiber is the quiet MVP of GI comfort on a GLP-1. Stir in yogurt or a scoop of protein and it earns its keep. Costco page
8. Kirkland Roasted Almonds (2.5 lb)
About 6g of protein per ounce at roughly 170 calories. Calorie-dense, so portion them into a little container instead of grazing from the bag — a handful, not a horizon. Costco page
9. Kirkland Frozen Organic Broccoli
Barely any calories — around 30 a serving — real fiber, and the kind of volume that fills a plate when your stomach wants bulk without the numbers. Keep a bag in the freezer for the nights you've got nothing green. Costco page
10. Kirkland Organic Hummus Cups
The pre-portioned cups solve the "I'll just have a little" problem a big tub never does. A little protein and some fiber — though worth knowing they're fat-forward at about 170 calories a cup, so treat them as a snack, not a free pass. Great with the broccoli above. Costco page
How to actually use this
A cart full of protein only helps if it turns into food you eat. The pattern most people settle into: one anchor protein for real meals (the chicken, the salmon, the eggs), one grab-and-go backup for the no-appetite days (yogurt, cottage cheese, a shake), and fiber on the side (oats, broccoli, hummus) to keep the GI side comfortable.
Tip
GLTrax check-ins track protein and fiber as separate numbers, day over day — so instead of guessing whether you're hitting your targets, you can watch the trend and bring the real picture to your next appointment.
