Kirkland Signature Canned Albacore Tuna - Best Zero-Point Protein
Kirkland's albacore tuna packed in water is a WW staple. With zero points on most WW plans, it delivers 20+ grams of protein per can at one of the lowest per-can prices you'll find anywhere. The 8-can pack keeps the pantry loaded for tuna salads, lettuce wraps, or pasta dishes where you want protein without burning points. The flavor is mild and the texture holds up well in recipes. Look for the water-packed variety specifically. oil-packed adds unnecessary fat and points. Drain thoroughly before weighing if you're tracking calories alongside points.

Kirkland Signature Canned Albacore Tuna - Best Zero-Point Protein
Kirkland's albacore tuna packed in water is a WW staple. With zero points on most WW plans, it delivers 20+ grams of protein per can at one of the lowest per-can prices you'll find anywhere. The 8-can pack keeps the pantry loaded for tuna salads, lettuce wraps, or pasta dishes where you want protein without burning points. The flavor is mild and the texture holds up well in recipes. Look for the water-packed variety specifically. oil-packed adds unnecessary fat and points. Drain thoroughly before weighing if you're tracking calories alongside points.
Fage Total 0% Greek Yogurt - Best High-Protein Snack
Fage 0% is one of the cleanest plain Greek yogurts on the market. no added sugar, no thickeners, just strained nonfat yogurt. At zero points on WW (plain, unflavored), it works as a breakfast base, a sour cream substitute, or a filling midday snack. The 4-pack at Costco brings the price per container well below supermarket rates. The thick, slightly tangy texture distinguishes it from thinner store-brand versions. Pair with fresh berries (also zero-point) for a satisfying low-point meal. Avoid the flavored Fage split cups at Costco. those carry added sugar and real points.
Kirkland Signature Frozen Edamame - Best Zero-Point Side Dish
Frozen shelled edamame is one of the most versatile zero-point vegetables in the WW pantry. Costco's Kirkland bag delivers 4 pounds at a competitive price. Steam a portion in two minutes and add it to salads, stir-fries, or eat it plain with a pinch of salt. The edamame holds its texture well after freezing and doesn't get mushy if you don't overcook it. It's one of the few zero-point foods that also feels like a real snack rather than just a side dish. High in fiber and plant protein, it keeps you full longer than most vegetable options.
Wonderful Pistachios No Shell - Best Smart Snack
Pistachios are not zero-point, but they are one of the most satisfying nuts per point spent. The no-shell variety at Costco removes the cracking effort, which makes overeating slightly easier. so portion control matters. A standard 1-ounce serving clocks in at a modest point value while delivering healthy fats, fiber, and around 6 grams of protein. Wonderful's quality is consistent; the nuts are fresh and lightly salted. Divide the bag into pre-portioned snack bags when you get home to avoid the mindless-eating trap that bulk bags invite. They travel well and keep hunger at bay between meals.
Kirkland Signature Rotisserie Chicken - Best Lean Meal Base
The Costco rotisserie chicken is a legend for a reason. A skinless breast from one bird is zero WW points and provides a meal's worth of protein in minutes. One chicken can power multiple lunches. chopped into salads, folded into lettuce wraps, or mixed into soup. The key for WW is removing the skin before eating, which is where most of the saturated fat lives. Buy one per week and portion it into containers immediately so you have grab-and-go protein ready throughout the week. The Kirkland seasoning is light enough that the chicken doesn't overwhelm other flavors in recipes.
Before you buy
What to consider
Focus on three filters: protein content, sugar content, and ingredient length. Foods with 15+ grams of protein per serving keep hunger in check. Items with less than 5 grams of added sugar per serving avoid hidden point traps. Short ingredient lists generally signal less processing and fewer additives that spike calorie density without satiety. At Costco, always flip the bulk-size package and read per-serving data rather than per-package. Many members fall into the trap of assuming Kirkland products are automatically healthy. check every label. Frozen vegetables, plain proteins, canned fish, and unsweetened dairy are the safest zones.
The wrap-up
Costco and Weight Watchers are a natural pairing when you know what to buy. Lean proteins, plain dairy, and zero-point vegetables in bulk keep the unit cost low while maintaining a solid WW-friendly pantry. Stick to the perimeter of the store where produce, proteins, and refrigerated basics live, and treat the sample stations and bakery section as the obstacle course they are.

Quick answers
Yes. Costco stocks a solid range of lean proteins, low-sugar snacks, and zero-point produce in bulk quantities. The per-unit cost is typically lower than grocery stores, making it practical for stocking up on WW staples like canned fish, Greek yogurt, egg whites, and frozen vegetables without breaking your weekly food budget.
Zero-point foods available at Costco include skinless chicken breast, canned tuna in water, plain nonfat Greek yogurt, frozen edamame, and most fresh or frozen vegetables. These are sold in large pack sizes, which works well for meal prepping through the week. Always verify current point values in the WW app as they update periodically.
Costco does not typically carry WW-branded products in-store. However, many of its Kirkland Signature products and national brand offerings align with WW-friendly eating. The key is checking nutrition labels for protein-to-calorie ratios and avoiding added sugar traps in items like flavored yogurts, granola bars, and trail mixes.
