High-protein foods—like meats, eggs, fish, and dairy products—tend to be some of the most expensive items in our shopping carts. If you’re trying to eat well but want to avoid sticker shock at the grocery store, consider hitting up Costco, where you’ll find the same high-quality foods at a bargain price compared to most grocery chains. If you’re already a member of the warehouse club, then you know it’s all about buying in bulk, which means you can stock up on high-protein snacks and meal ingredients that will keep you full and energized throughout the day.
As for how much protein you should eat daily, a good rule of thumb is to strive to get about 1 gram of protein per every pound of lean body mass. For example, if you weigh 130 pounds and your body fat is 25 percent, that means you have about 100 pounds of lean body mass. Your optimal protein intake would be 100 grams of protein per day. It’s also best to spread out protein evenly throughout the day, ideally with 20 to 30 grams at each main meal. Eating more than 40 grams of protein in one sitting is not beneficial, and those calories may be stored as body fat.
Costco has great, affordable protein finds in virtually every section of the grocery department. You can find plenty of the usual suspects like dairy, eggs, and meats, but a more thorough exploration of the aisles will reveal many other great high-protein foods—all at a major cost savings compared to ordinary grocery stores. Here are 20 of the best dietitian-recommended protein finds to score at Costco.
