20 Keto-Friendly Staples Americans Reach For
Animal proteins (staples for keto followers)
-
Seafood — Salmon, sardines, mackerel, and other fatty fish are near zero-carb, rich in omega-3s and B vitamins. Shellfish like shrimp and many crabs are also virtually carb-free; oysters and octopus have modest carbs and should be tracked as part of total net carbs.
-
Meat and poultry — Fresh cuts of beef, pork, chicken, and turkey contain essentially no carbs and supply high-quality protein and B vitamins. Grass-fed options provide slightly more omega-3s and conjugated linoleic acid (CLA).
-
Eggs — A quintessential keto staple, whole eggs deliver protein, fat, and micronutrients with less than 1 g of carbs each. Eat the yolk: that’s where lutein, zeaxanthin, and most nutrients live.
Dairy and dairy alternatives (low-carb, high-fat choices)
-
Cheese — Most cheeses are low in carbs and rich in fat and calcium. Cheddar, mozzarella, blue cheese, brie, and Parmesan are frequently listed among keto cheese picks.
-
Plain Greek yogurt & cottage cheese — Both contain some carbs but are protein-rich; choose full-fat, plain versions and measure portions to keep net carbs in range.
-
Cream and half-and-half — Useful for coffee and recipes, heavy cream is low in carbs and high in fat; enjoy in moderation.
-
Unsweetened plant-based milk — Almond, soy, and coconut milks (unsweetened) offer low-carb alternatives to dairy milk. Avoid oat milk on strict keto — even unsweetened versions can be too carbohydrate-heavy.
Vegetables (low-carb volumes, nutrient density)
-
Green leafy vegetables — Spinach, kale, collards, arugula, and romaine are very low in carbs and loaded with vitamins and antioxidants — ideal for bulking meals without spiking net carbs.
-
Peppers — From jalapeños to bell peppers, these add flavor, color, and vitamins; count larger quantities of sweet peppers toward daily carbs.
-
Summer squash — Zucchini and yellow squash are versatile: spiralize as zoodles, grate into batters, or grill as a side dish.
-
High-fat veggies (avocado and olives) — Technically fruits, both are celebrated on keto for healthy fats, fiber, and low net carb impact.
-
Other non-starchy vegetables — Asparagus, broccoli, cauliflower, mushrooms, cucumber, eggplant, and Brussels sprouts make frequent appearances on keto-friendly vegetable lists because they substitute well for starches (cauliflower rice, mashed cauliflower).
Plant-based foods and snacks
-
Nuts and seeds — Almonds, macadamias, pecans, walnuts, chia, and flax are high in fat and fiber; carb counts vary so portion control matters.
-
Berries — Raspberries and strawberries are the most keto-friendly berries thanks to higher fiber and lower sugar; blueberries and blackberries can fit in more moderate approaches.
-
Shirataki noodles — Made from glucomannan fiber, these carry less than 1 g net carbs and can replace pasta in many recipes for keto followers craving texture.
Sweets, fats, and oils
-
Dark chocolate and cocoa powder — Choose chocolate with 70% cacao or higher and enjoy small portions; cocoa powder can flavor keto desserts with minimal carbs.
-
Olive oil — A monounsaturated fat powerhouse, olive oil is carb-free and excellent for dressings and low-heat finishing.
-
Butter and ghee — Carb-free dairy fats commonly used for cooking and flavor. Ghee is clarified butter with milk solids removed, often tolerated by those reducing lactose.
Beverages (carb-free hydration and caffeine)
-
Unsweetened coffee and tea — Both are carb-free beverages favored on keto; add cream or half-and-half in measured amounts if desired.
-
Unsweetened sparkling water — A soda alternative with zero calories and zero carbs; verify flavored varieties for hidden fruit juices.
Practical tips for counting carbs and keeping variety
-
Track net carbs (total carbs minus fiber) if you prefer that approach it’s how many digestible carbs affect blood glucose.
-
Rotate the list: combine animal proteins, keto-friendly vegetables, and healthy fats (olive oil, avocado, butter) to maintain nutrient diversity and avoid monotony.
-
Read labels: plant-based milks, yogurts, and flavored beverages can hide sugars that push you beyond 20–50 grams per day.
