protein food items like beef, salmon, eggs and cheese on a chalkboard with a chalk outline of an arm with a bicep around it

My clients often struggle with shopping for the right groceries that will deliver the protein they need to build muscle, boost their metabolism, or lose weight. So I put together this grocery guide, broken out into 4 categories – Meat Proteins, Non-Meat Protein, High-Protein Carbohydrates, and Healthy Fats.  All the foods listed here can be purchased locally in the Denver region and can be used together to make delicious meals you’ll love.

MEAT PROTEINS

1. Grass-Fed Beef

Grass-fed beef is high in omega-3 fatty acids and offers a lean, clean source of protein. Unlike conventional red meat, it’s less inflammatory and packed with nutrients that support heart health.

Buy it at: King Soopers. King Soopers is affordable, widely available, and carries the Simple Truth Organic brand, which offers 97.3% lean ground beef options.

Pro tip: Look for 97.3% ground beef for the best balance of flavor and lean protein.

2. Pasture-Raised Chicken

Pasture-raised chicken is lower in calories and free from added hormones and antibiotics, which makes it a safer, cleaner food choice, especially for families with kids.

Buy it at: King Soopers: They carry organic pasture-raised options, again under the Simple Truth brand.

3. Wild-Caught Salmon or Tuna

Packed with omega-3s and protein, wild-caught fish like salmon and tuna beat out their farm-raised counterparts for nutrition and taste. Eat it twice a week and you can skip the omega-3 supplements.

Buy it at: King Soopers or Sprouts.

NON-MEAT PROTEIN

4. Eggs

Eggs are a complete protein, with a nearly perfect protein-to-calorie ratio (6g protein for just 70 calories). Look for darker amber yolks — that’s a sign of higher nutrient content.

Recommended brands: The Happy Egg Co., Alfalfas
Buy them at: King Soopers
Pro tip: Check brand ratings at Cornucopia.org for transparency on sourcing.

5. Greek Yogurt or Cottage Cheese

Versatile, high in protein, and low in calories. Perfect for snacks, smoothies, or cooking and baking.

Recommended brands: FAGE, Chobani
Buy them at: King Soopers

6. Tofu

One of the highest-protein plant-based foods, and a great option for non-meat eaters. It’s a complete protein and super flexible in recipes.

Buy it at: King Soopers or Sprouts.

HIGH-PROTEIN CARBOHYDRATES

7. Sprouted Whole Grain Bread

Unlike traditional bread, sprouted bread (like Ezekiel 4:9) contains living nutrients, fewer preservatives, and better digestion properties.

Buy it at: Look in the freezer section of Sprouts or King Soopers.

8. Sweet Potatoes

The natural sugars in sweet potatoes are minimal and come with protein, fiber, nutrients, and serious staying power.

Buy them at: Sprouts or local farmer’s markets like Union Station Farmers Market or Cherry Creek Fresh Market.

9. Steel Cut Rolled Oats

A fiber-rich, versatile complex carb that can be enjoyed hot or cold. Best balance between processing and convenience. Steel cut oats are the least processed, that’s why I recommend them.

Buy them at: Sprouts (especially for bulk bins and premium brands).

HEALTHY FATS

10. Lentils or Beans (Black or Pinto)

Lentils and beans – either black or pinto – are loaded with fiber and healthy fat. They are also easy to prep in bulk.

Buy them at: King Soopers or any local grocer.

11. Almonds

Almonds are balanced between the three main macronutrients (protein, carbohydrates, and fats) and pair very well with high-protein foods like Greek Yogurt.

Buy them at: Sprouts or any local grocer.
