Top 10 essential keto foods to always keep in your pantry

Eggs are considered a staple in the ketogenic diet due to their negligible carbohydrate count and exceptional nutritional value.

Key benefits: eggs offer exceptional nutritional value and are an affordable source of protein and fat. They contain choline, an essential nutrient vital for brain development — particularly important for women of childbearing age. Eggs also promote satiety, helping to reduce appetite and manage energy levels effectively.

Clinical insight: concerns regarding dietary cholesterol from eggs have largely been mitigated by recent research, which suggests that consuming one egg per day is acceptable for most individuals. The yolk should be consumed, as it contains the antioxidants lutein and zeaxanthin, which protect eye health.

Avocados stand out as one of the few fruits low enough in sugar and high enough in fat to be central to a ketogenic diet. For a deeper look at fruit choices on keto, see our keto fruit medical guide.

Key benefits: avocados are rich in monounsaturated fats, promoting heart health, and are an excellent source of fiber, which aids in digestion and prolongs feelings of fullness. Half an avocado contains about 487 mg of potassium — roughly 10% of the recommended daily value — a mineral crucial for normalizing blood pressure and mitigating keto flu symptoms.

Usage: the neutral flavor makes avocados suitable for direct consumption, or inclusion in sauces, salads, and dressings. Regular consumption is linked to reducing levels of LDL (“bad”) cholesterol.

Fatty fish and most seafood are nearly carb-free and provide high-quality protein and essential fats, making them ideal keto foods.

Top choices: salmon, mackerel, sardines, tuna, shrimp, and crab.

Key benefits: fatty fish are exceptionally rich in omega-3 fatty acids (DHA and EPA). Omega-3s are vital components of cell membranes, supporting better brain function, immunity, and cardiovascular health. Studies indicate that omega-3 intake may help lower insulin levels and improve insulin sensitivity.

Clinical insight: sardines are particularly valuable, offering high omega-3 levels with low mercury content, along with calcium and vitamin D that support bone health. When preparing seafood, avoid carb-heavy breading or added sugars.

While the keto diet restricts starchy vegetables like potatoes and corn, non-starchy varieties are crucial for providing fiber, micronutrients, and antioxidants. See the full keto vegetables list ranked by net carbs for a comprehensive overview.

Best low net carb options:

• Leafy greens: spinach, kale, collard greens, and cabbage are packed with vitamin K and iron.
• Cruciferous vegetables: broccoli, cauliflower, and Brussels sprouts are high in fiber and micronutrients. Cauliflower is especially versatile — often used as a substitute for rice or mashed potatoes.
• Squashes and alternatives: zucchini (spiralized into “zoodles” to replace pasta) and summer squash are excellent low-carb options.

Gut health note: compounds in mushrooms (like portobello) stimulate the growth of healthy gut bacteria, promoting a balanced microbiome. Adequate fiber intake from these sources is crucial to prevent constipation and support gut health — which can be challenging on a carb-restrictive diet.

Nuts and seeds are excellent high-fat, low-carb options, providing plant protein, fiber, vitamins, and minerals including calcium and magnesium.

Recommended low-carb varieties: macadamia nuts, pili nuts, walnuts, pecans, almonds, chia seeds, and flaxseeds.

Key benefits: regular consumption is associated with a reduced risk of chronic conditions including heart disease and diabetes. Their high fiber content enhances satiety, potentially assisting with weight management.

Seeds spotlight: chia seeds are particularly rich in fiber (11g per ounce), aiding in fullness and linked to improved heart health and lower cholesterol.

Cheese aligns perfectly with the keto diet as a naturally high-fat, low-carb food that also provides a good source of protein and calcium.

Keto cheese options: cheddar, blue cheese, mozzarella, Swiss, Colby, feta, halloumi, and cream cheese are generally very low in carbohydrates. Cheddar, Colby, and mozzarella are also lower-lactose varieties.

Key benefits: cheese is often made from simple ingredients — milk, salt, enzyme, bacteria. It is also a fermented food, acting as a source of probiotics that support a strong digestive system and overall health.

Consumption note: while cheese is rich in saturated fat, emerging research suggests that not all saturated fats are equal and some may promote heart health. Nonetheless, consumption should remain moderate, especially for those focused on weight loss, due to its calorie density.

Olive oil is a healthy, carb-free fat source and a cornerstone of the Mediterranean dietary pattern, widely recommended for heart health.

Key benefits: olive oil is abundant in monounsaturated fats (oleic acid) and polyphenol antioxidants that combat inflammation and disease. Research links olive oil consumption to promoting heart health, managing blood pressure, and potentially protecting against certain cancers.

Recommendation: extra virgin olive oil (EVOO) is generally preferred because it is the least processed, containing higher concentrations of phenols which may offer enhanced antioxidant effects. EVOO is best used for low-heat cooking or as a base for salad dressings and marinades.

Meat and poultry are zero-carb staples of the keto diet, providing high-quality protein necessary for maintaining muscle mass — especially important during weight loss. See our guide on how much protein to eat on keto to calibrate your intake correctly.

Zero-carb options: beef, chicken, pork, turkey, lamb, and venison.

Key benefits: fresh meat and poultry are rich sources of essential nutrients including B vitamins, iron, zinc, and selenium. Choosing fattier cuts — such as chicken thighs or sirloin steak — helps meet the high-fat macronutrient targets of the diet.

Processed meat caution: while processed meats like bacon or some sausages are low-carb, they should be consumed in moderation. High consumption may be linked to health conditions including heart disease and type 2 diabetes. Grass-fed meat is often preferred as it contains more omega-3 fats and conjugated linoleic acid (CLA).

Although most fruits are restricted due to high sugar content, berries are a notable exception on a ketogenic diet.

Best low-carb berries: raspberries and strawberries are the lowest in net carbs. Blackberries and blueberries can be included but contain slightly more carbohydrates. For a full breakdown, see our keto fruit guide.

Key benefits: berries are rich in antioxidants — including anthocyanins and ellagitannins — that help reduce inflammation and protect against cell damage. They also contain fiber, which helps enhance satiety.

Portion management: berries should still be consumed in measured, small quantities to ensure carb limits are maintained. Consider mixing them into high-fat dairy or using as a dessert topping rather than eating by the handful.

Butter and ghee (clarified butter) are valuable keto foods because they are essentially pure fat sources with virtually no carbohydrates.

Ghee specifics: ghee is made by heating butter and removing milk solids, resulting in a carb-free product commonly used in cooking. It contains butyric acid — a short-chain fatty acid that supports the gut’s endothelial cells.

Usage: excellent for cooking eggs, fish, and meats. They can also be added to coffee or smoothies — for example, as the fat component in Bulletproof Coffee (BPC) — to increase fat intake and energy levels quickly.
