That's why having a few foods to help decrease the belly bloat and give you a flat belly is important to have on hand. Especially if some of those foods can be found at one of your favorite retailers—Costco!

We spoke with a few registered dietitians in order to determine which Costco foods to buy. Whether you need to decrease belly bloat or simply keep that belly fat, here's what they recommend buying, and for even more Costco shopping tips, be sure to check out our list of the Costco Foods You Should Always Avoid, According to Nutritionists.


Avocados, 5-Pack

"You can find bags filled with multiple avocados at Costco," says Mackenzie Burgess, RDN, registered dietitian nutritionist and recipe developer at Cheerful Choices. "One medium avocado packs in about 760 grams of potassium which provides over 20% of our recommended daily intake. Consuming potassium-rich foods is important because potassium helps regulate our fluid balance, and can help decrease water retention. If you end up with extra avocados on their last leg, try mashing and adding to healthier truffles."

Here are 8 Avocado Health Benefits That Prove It's a Perfect Weight Loss Food.


Teton Waters Sausage

"When it comes to the meat section, many products are filled with excess sodium or unfamiliar food additives that can lead to unwanted bloating," says Burgess. "Instead, one of my favorite finds at Costco are Teton Waters Ranch Polish Sausages. These sausages have real ingredients you can pronounce and contain less sodium and saturated fats than most options. Try pairing with roasted sweet potatoes or zucchini noodles for a satisfying dinner."


Bob's Red Mill Oatmeal Cups

"Take the fuss out of making your own oatmeal and opt for these single serving oatmeal cups that are ready to go," says Burgess. "I love grabbing Bob's Red Mill oatmeal cups because they are filled with clean ingredients and pack in 7 grams of dietary fiber per oatmeal cup. This fiber keeps our digestive system moving and may help reduce belly bloat."

"To help reduce bloating, make sure you consume plenty of fiber along with lots of water," says Amy Goodson, MS, RD, CSSD, LD, author of The Sports Nutrition Playbook. "Fiber helps push 'stuff' through your system and can help you from feeling bloated. Snack time can be a great place to get more fiber in your day and Kirkland Signature Snacking Nuts are the perfect option. Individually packaged, you can throw these bags of nuts in your desk, purse, or computer bag and have a pop of fiber any time of day to help keep 'stuff' moving through your gastrointestinal tract!

"Water has a positive effect on metabolism, satiety, and overall hydration, which can support weight loss," says Jessica Bippen, RD for Essentia Water. "Water may help fill you up—as thirst can often be confused with hunger—especially if you drink it before eating a meal. (A small study of 15 young, healthy participants that was published in October 2018 in Clinical Nutrition Research). I feel hydrated, energized, and mentally sharp. Plus, it's the purest tasting water so it makes staying hydrated enjoyable."
