Snacking can be one of the trickiest parts of losing weight. While it’s easy to reach for chips, candy, or other convenient foods, many options sabotage your progress and leave you feeling sluggish. Fortunately, fat loss experts Christian Foss and Bella have shared their favorite Costco snacks that actually support weight loss. These picks are designed to satisfy cravings, provide protein and fiber, and keep your metabolism running strong, all without derailing your goals. If you want snacks that are both convenient and effective, here’s what they recommend keeping on hand.
1. Siete chips
Christian Foss swears by Siete chips for those moments when you crave something crunchy. Made with avocado oil, these chips are grain-free, gluten-free, and only 25 calories per serving. They provide the satisfying texture of a fried snack without the unhealthy fats and excess calories that typically come with traditional chips, making them a perfect swap for anyone trying to stay on track.

2. Fruit bars
For a quick sweet fix, Foss recommends simple fruit bars. These bars contain just two ingredients, are sugar-free, and clock in at only 60 calories each. They’re perfect for keeping your sweet tooth in check while avoiding the blood sugar spikes and crashes that come with processed treats.

3. Prana Flavored Bean Mix in Sriracha
Another favorite of Foss’s is the Prana Flavored Bean Mix in Sriracha, which packs 12 grams of protein per serving. Gluten-free and dairy-free, this snack is not only filling but also provides gut-friendly fiber and plant-based protein, making it an excellent choice for a mid-afternoon boost.

4. Pre-packaged corn snacks
Bella, a fellow fat loss coach, shares her go-to pre-packaged corn snacks for quick, low-calorie crunch. Each bag contains just 90 calories and comes pre-portioned, which helps prevent mindless snacking and keeps your daily calorie goals in check.

5. Grenade Bars
If you’re craving something decadent, Bella suggests Grenade Bars. Pop one in the microwave for 10 seconds, and you’ve got a molten lava-style treat with 22 grams of protein. It’s a sweet indulgence that feels like a dessert but actually supports your fat loss goals.

6. Mush Overnight Oats
Finally, Bella recommends Mush Overnight Oats, made with wholesome, whole-food ingredients. When paired with a protein shake, they make a balanced, nutrient-rich snack that keeps you full and nourished between meals, without excess sugar or processed fillers.
Weight loss doesn’t mean cutting snacks out of your diet entirely. By keeping these six Costco-approved options on hand, you can satisfy cravings, fuel your body, and stay on track toward your goals. From crunchy chips to protein-packed bars and wholesome overnight oats, these snacks make it easy to snack smarter while supporting fat loss and overall wellness.
