Top High-Protein, High-Fiber Costco Foods for Weight Loss

A dietitian reveals the best high-protein, high-fiber Costco bulk foods for effective weight loss.

Health professionals often recommend Costco for its healthy food options, and dietitian Tara Collingwood recently shared her top picks. Collingwood, a Board Certified Sports Dietitian and co-author of the Flat Belly Cookbook for Dummies, emphasizes the importance of nutrient-dense, minimally processed foods for weight management. “These foods work because they help with satiety, blood sugar control, and overall diet quality,” she explains.

Here are nine bulk items from Costco that dietitians recommend for weight loss:

Kirkland Organic Greek Yogurt

“High protein content helps fill you and preserve muscle mass during weight loss,” says Collingwood. “It does contain natural lactose, but it has zero added sugar.” The yogurt is also noted for its creamy texture.

Kirkland Shelled Hemp Hearts

Collingwood recommends Kirkland Shelled Hemp Hearts for their healthy fats and minerals. “Fats help with satiety, but portion size matters because they’re calorie-dense,” she warns.

Wild Caught Sockeye Salmon

Dump dish or pan fry? Wild Caught Sockeye Salmon is rich in protein and omega-3 fatty acids. “A good option for balanced meals,” says Collingwood.

Kirkland Almond Flour

Collingwood describes Kirkland Almond Flour as lower in carbs compared to traditional flour, but notes that it’s calorie-dense. “Control portions for weight-loss benefits,” she advises.

Rotisserie Chicken

A popular choice among shoppers, Costco’s rotisserie chicken is a convenient, protein-rich option. “Removing the skin can reduce saturated fat and calories,” recommends Collingwood.

Kirkland Frozen Organic Berries

High in fiber and antioxidants, Kirkland Frozen Organic Berries contain no added sugar. “These are great for weight management,” Collingwood notes.

Boneless Skinless Chicken Breast from Kirkland

A staple protein that is high in protein and low in fat, Kirkland Boneless Skinless Chicken Breast is versatile and supports muscle maintenance, according to Collingwood.

Kirkland Walnuts

Kirkland Walnuts offer heart-healthy fats and fiber. “They can help with fullness but are calorie-dense, so portion-awareness is key,” Collingwood advises.

Season Brand Sardine Fillets

Finally, sardine fillets are another protein-packed, heart-healthy option. “They are nutrient-dense and satisfying,” concludes Collingwood.
