FACT CHECKED BY Alexa Mellardo

Costco is known for bulk food shopping, ready-to-heat meals, and a wide array of home items. The sheer number of foods available at Costco can be overwhelming to sift through, so we've broken down the 10 best Costco frozen foods for weight loss. Frozen foods can make mealtime more convenient, providing options that are fully cooked and require minimal prep time. This section of the store can also be packed with high-calorie desserts and appetizers, enticing pizzas, and other treats that could make weight loss more challenging.

When weight loss is your goal, there are a few factors that can help you decipher which frozen foods to bring home:

  • Individually portioned items are helpful. Whether a serving of meat, a sandwich, or an entire meal, single-serving packages can make it easier for you to stick with a reasonable portion.
  • Limit fried options. While some of these can fit into a weight loss diet, most of them will add excess empty calories without being very filling.
  • Watch for added sugar. Desserts and entrees are both culprits of added sugar, so take a look at the nutrition facts panel before adding an item to your basket. Savory foods with sauces are an especially sneaky source of sugar to look out for.

When in doubt, when it comes to what to buy in the frozen food section, load up on fruits, veggies, and lean protein. These options are always available, and you can typically find a variety of foods in each category. This can lead to simple meals that keep you full and satisfied without the added sugar, salt, and preservatives found in many frozen items. Here are the 10 best Costco frozen foods for weight loss. Keep reading to learn all about them, and when you're finished, don't miss the 10 Best Trader Joe's Frozen Foods for Weight Loss.

Salmon is a great source of protein and provides essential omega-3 fats. While protein is great for weight loss, the Kirkland Signature Wild Alaskan Sockeye Salmon is especially helpful as the fish comes individually packed in 5 to 7-oz portions. This helps with portion control and allows you to cook only as much as you need for a single meal. If you find yourself wanting a smaller portion, simply split it in half, and save part of the salmon for a later meal. However, a 5-oz portion is a hearty serving of filling protein to keep you full and satisfied.
