If you’ve ever walked into Trader Joe’s with a plan and left with cookie butter, truffle chips, and a mystery snack you don’t remember throwing into your cart, you’re not alone. The store is full of very tempting options, but not all of them support your weight loss goals. Luckily, with a little strategy (and a few go-to staples), you can stay on track and make the most out of your grocery all.
We spoke to Registered Dietitian Kristen Kuminski, RD, CDN—who specializes in metabolic health and weight management—to gather a list of the exact Trader Joe’s items she recommends buying every week. These foods are high in protein, rich in fiber, and easy to work into everyday meals.
The Difference Between Dragging Through Your Day And Feeling Great On Your Feet? These Arch Support Insoles
1. Egg Whites in a Carton
If you’re looking for a low-calorie protein boost, egg whites are about as efficient as it gets.
"Egg whites in a carton [are] pure protein with almost no calories, easy to add to anything," Kuminski says.
Pour them into scrambles, mix them into oatmeal, or add them to veggie-packed stir-fries. They’re incredibly versatile and help increase satiety without adding much fat or calories.
2. Canned Wild Salmon
Canned fish might not be glamorous, but it’s one of the most underrated weight-loss staples.
"Canned wild salmon [is] high protein, omega-3s, and it keeps forever," Kuminski explains.
It’s shelf-stable, budget-friendly, and perfect for quick lunches. Just mix with mustard or Greek yogurt and throw it over greens or into a wrap.
3. Frozen Edamame
When snack time rolls around, protein and fiber are your best friends—and edamame delivers both.
"Frozen edamame [is a] great snack, high protein and fiber, keeps you full," she says.
Keep a bag in your freezer and portion it out when you need something satisfying between meals. It’s also great tossed into salads or grain bowls.
4. Lentil Soup
Not all convenience foods are created equal, but this one earns a spot in your cart.
"Lentil soup [is] one of the most filling things in the store for the price, fiber and protein in one," Kuminski notes.
It’s a quick, hearty option that actually keeps you full—making it ideal for busy days when cooking isn’t happening.
5. Full-Fat Greek Yogurt
If you’ve been reaching for low-fat yogurt in the name of weight loss, you might want to reconsider.
"Greek yogurt, the full fat version actually keeps hunger down better than low fat," she says.
The added fat helps with satiety, meaning you’re less likely to go searching for snacks an hour later. Pair it with fruit, nuts, or a drizzle of honey for a balanced breakfast or snack.
6. Frozen Riced Cauliflower
This is one of the easiest ways to lower carbs without feeling like you’re eating less.
"Frozen riced cauliflower swaps into almost anything to cut carbs without cutting volume," Kuminski explains.
Mix it into rice, stir it into soups, or use it as a base for bowls. You’ll still get a full plate, but with fewer calories.
7. Everything But the Bagel Seasoning
You won't want to eat healthy food if it tastes bland! That’s where this cult-favorite seasoning comes in.
"Making healthy food actually taste good is half the battle," Kuminski reminds us. Sprinkle it on eggs, avocado toast, roasted veggies, or whatever your heart desires. Flavor matters more than people think when it comes to long-term success.
Kuminski's final word of advice? "Stick to the perimeter and the freezer section," she says. "The middle aisles at Trader Joe's are where the interesting-looking snacks live and most of them aren't doing you any favors." The truth hurts!
That doesn’t mean you can never grab a treat—but if your goal is weight loss, building your cart around whole, protein-rich, and fiber-packed foods will make everything easier.
