Your Comprehensive Guide to High Fat Low Carb Foods for a Ketogenic Diet

Embarking on a ketogenic journey? Navigating the world of high-fat, low-carb foods can feel overwhelming at first. This guide simplifies your grocery shopping, ensuring you maintain stable blood sugar levels and effectively support your weight loss goals.

Adopting a higher-fat dietary approach means a shift in macronutrient ratios, and understanding which fats, proteins, and carbohydrates are keto-friendly is essential. Keep this list handy whether you’re planning your meals at home or ordering food on the go.

The Essential High-Fat, Low-Carb Food List

Healthy Fats and Oils

Fat is not the enemy; it’s your primary fuel source on a ketogenic diet. However, the type of fat you consume matters greatly. Prioritize a diverse intake of fats, including omega-3, omega-6, omega-9, and naturally occurring saturated fats. Trans fats are the only fats you should strictly avoid. Here are excellent fat sources to incorporate into your keto lifestyle:

Ghee: A lactose-free butter alternative, rich in fat-soluble vitamins.
Grass-fed butter: Offers a richer flavor and higher nutrient profile compared to conventional butter.
Lard: Rendered pork fat, a traditional cooking fat high in monounsaturated fat.
Tallow: Rendered beef fat, another excellent source of monounsaturated and saturated fats.
Avocado oil: High in monounsaturated fats and beneficial for heart health, ideal for cooking and salad dressings.
Coconut oil: A source of medium-chain triglycerides (MCTs), which can be quickly converted into ketones.
Sesame seed oil: Adds a nutty flavor and provides polyunsaturated fats.
Almond oil: Mild flavor, rich in vitamin E and monounsaturated fats.
Olive oil: A Mediterranean staple, packed with antioxidants and heart-healthy monounsaturated fats.
Sunflower seed oil: Provides vitamin E and omega-6 fatty acids, use in moderation due to omega-6 content.

Quality Protein Sources

A common misconception is that the keto diet is extremely low in protein. In reality, adequate protein intake is crucial for most individuals on keto. Protein is vital for muscle growth, repair, maintenance, and supporting a healthy metabolism.

Just as with fats, protein quality is paramount. Opt for organic and pasture-raised options whenever feasible. For beef, grass-fed is nutritionally superior to grain-fed.

Here’s a selection of high-fat, high-protein foods perfect for keto:

Grass-fed beef: Rich in omega-3 fatty acids and essential nutrients.
Chicken (wings, breasts with skin, thighs): Choose cuts with skin and bone for higher fat content.
Ham: A versatile protein source, check labels for added sugars.
Lamb (especially the loin): Flavorful and naturally high in fat, especially cuts like loin and shoulder.
Venison: Lean yet offers a good protein and fat profile, depending on the cut.
Bison: Similar to beef but often leaner, choose fattier cuts.
Salmon: An excellent source of omega-3 fatty acids and high-quality protein.
Mackerel: Another fatty fish rich in omega-3s and vitamin D.
Sardines: Small, nutrient-dense fish packed with omega-3s and calcium.
Tuna: Choose oil-packed for added fat, a convenient protein source.
Eggs: A nutritional powerhouse, versatile and rich in healthy fats and protein.

Focus on whole animal foods with minimal processing and no added sugars. Always scrutinize labels for hidden carbohydrates, especially in packaged meats. Prioritize fatty cuts of meat and fatty fish over leaner options to meet your fat macros.

Low-Carb Vegetables for Keto

A wide array of vegetables are compatible with a low-carb diet. While not typically high in fat, vegetables are essential for micronutrients, fiber, and overall health on keto. Here’s a list of popular low-carb vegetable choices:

Broccoli: A cruciferous vegetable, rich in vitamins and fiber.
Bok choy: A mild-flavored leafy green, versatile in stir-fries and salads.
Brussels sprouts: Another cruciferous veggie, roasting enhances their flavor.
Asparagus: A spring vegetable, delicious grilled, roasted, or steamed.
Kale: A nutrient-dense leafy green, great in salads, soups, or baked into chips.
Chard: Similar to spinach, with vibrant stalks and mild leaves.
Spinach: A versatile leafy green, packed with vitamins and minerals.
Peppers (bell peppers, chili peppers): Add flavor and color, lower in carbs than many other vegetables.
Celery: Crunchy and hydrating, a low-carb snack or addition to salads and soups.
Cauliflower: Extremely versatile, can be riced, mashed, roasted, or used as a pizza crust.
Cucumber: Refreshing and hydrating, excellent in salads or as a snack.
Zucchini: Mild flavor, can be spiralized into noodles or added to various dishes.
Summer squash: Similar to zucchini, versatile and low-carb.
Tomatoes: Technically a fruit but used as a vegetable, enjoy in moderation.
Cabbage: Affordable and versatile, can be used in salads, slaws, or stir-fries.
Green beans: A good source of fiber, enjoy steamed, roasted, or sautéed.
Radish: Peppery and crunchy, adds zest to salads.
Alfalfa sprouts: Light and fresh, adds texture to salads and sandwiches.
Onions: Flavorful, use in moderation as carbs can add up.
Lettuce (all varieties): Base for salads, wraps, and adds crunch.
Mushrooms (all varieties): Earthy flavor and unique texture, sautéed, roasted, or grilled.

Keto-Friendly Dairy Options

Dairy can be a point of confusion on keto due to the natural sugars (lactose) in milk products. While some dairy items, like sugary yogurts or ice cream, are off-limits, many full-fat dairy options are perfectly suitable for a ketogenic diet. These include:

Greek yogurt (full-fat, plain): High in protein and fat, choose plain varieties to avoid added sugars.
Heavy whipping cream: High in fat, perfect for coffee, sauces, and desserts.
Cottage cheese (full-fat): A good source of protein and fat, choose full-fat versions.
Cream cheese: High in fat, used in dips, desserts, and savory dishes.
Sour cream (full-fat): Adds tanginess and fat to dishes, choose full-fat.
Mascarpone: Rich and creamy Italian cheese, excellent in desserts and sauces.
Mozzarella cheese: Versatile cheese, great for pizza, salads, and snacks.
Blue cheese: Strong flavor, adds depth to salads and sauces.
Monterey jack cheese: Mild and melts well, good for quesadillas and omelets.
Feta cheese: Crumbly and salty, adds flavor to salads and Mediterranean dishes.
Parmesan cheese: Hard, flavorful cheese, grated over dishes or enjoyed in chunks.
Cheddar cheese: A classic cheese, various sharpness levels, great for snacks and cooking.
Swiss cheese: Mild and nutty, good for sandwiches and snacking.

Nuts and Seeds for Healthy Fats

Most nuts and seeds are naturally high in fat and low in carbs, making them excellent keto snacks and additions to meals. Here’s a list of keto-friendly nuts and seeds. Remember that nut butters are also acceptable, but always check ingredient labels for added sweeteners or fillers. Some nuts, like cashews and pistachios, should be consumed in moderation due to their slightly higher carb content compared to others.

Almonds: Versatile nut, eaten whole, sliced, or as almond flour.
Macadamia nuts: Highest in fat and lowest in carbs among nuts, creamy texture.
Cashews (moderation): Enjoy in smaller portions due to higher carb count.
Peanuts: Technically legumes, but commonly used as nuts, good source of protein and fat.
Pecans: Buttery and rich, excellent in desserts and snacks.
Brazilian nuts: High in selenium, enjoy in moderation due to selenium content.
Pine nuts: Delicate flavor, used in pesto and salads.
Pistachios (moderation): Enjoy in smaller portions due to higher carb count.
Chestnuts: Lower in fat and higher in carbs compared to other nuts, use sparingly.
Walnuts: Rich in omega-3 fatty acids and antioxidants.
Pumpkin seeds: Nutritious seeds, roasted or added to salads.
Sesame seeds: Nutty flavor, used in Asian cuisine and tahini.
Sunflower seeds: Good source of vitamin E, enjoy as a snack or in salads.
Hemp seeds: Complete protein source, mild flavor, sprinkle on salads or yogurt.
Chia seeds: High in fiber and omega-3 fatty acids, used in puddings and smoothies.
Flaxseeds: High in fiber and omega-3 fatty acids, ground flaxseeds are best for absorption.

Low-Carb Fruits: Enjoy in Moderation

While most fruits are higher in sugar and carbs, a select few can be enjoyed in limited quantities on a low-carb diet. Avocados are the only naturally high-fat fruit, but other low-carb fruit options exist.

Avocados: Creamy and rich in monounsaturated fats, a keto superfood.
Limes: Zesty and low in carbs, use juice and zest for flavor.
Lemons: Similar to limes, low-carb and adds acidity to dishes and drinks.
Berries (raspberries, blueberries, strawberries, cranberries, blackberries): Lower in carbs compared to other fruits, enjoy in small portions.

Berries should always be consumed in moderation on keto. While lower in carbs than many fruits, the carbs can accumulate quickly if you overindulge.

Keto-Friendly Beverage Choices

Many popular beverages are laden with sugar, making them unsuitable for a ketogenic diet. A significant portion of adults consume sugary drinks daily, unaware of their high carb content. Just 12 ounces of soda can contain a staggering amount of sugar and carbohydrates, instantly derailing ketosis.

The primary rule for keto beverages is to avoid sugar-sweetened drinks. While it’s obvious that sodas are off-limits, many other seemingly “healthy” drinks are also sugar bombs. High-fat beverages are less common but can be incorporated. Here are keto-friendly drinks that can even add a boost of healthy fats:

Butter coffee (with added butter and MCT oil): A ketogenic coffee upgrade, providing sustained energy and fat.
Tea (black, green, white, herbal) with heavy cream: Unsweetened tea with a splash of heavy cream adds fat without carbs.
Coffee (with heavy cream or coconut cream, no sugar): Similar to tea, coffee with heavy cream or coconut cream is keto-friendly.
Smoothies (using fat sources like avocado, peanut butter, and MCTs): Blend low-carb fruits and vegetables with healthy fats for a keto smoothie.
Bone broth: Nourishing and hydrating, can be sipped warm or used as a base for soups.

Foods to Avoid on a High-Fat, Low-Carb Diet

Just as important as knowing what to eat is understanding what to avoid on a keto diet to maintain ketosis and stable blood glucose. Here are key food categories to limit or eliminate:

Most Fruits: High in Natural Sugars

While fruits are sources of vitamins and fiber, most are too high in carbohydrates and natural sugars to fit into a strict ketogenic diet. With the exception of the keto-friendly fruits listed above, avoid most other fruits, including high-sugar options like bananas, apples, oranges, grapes, mangoes, and dried fruits.

Starchy Vegetables: High in Carbohydrates

Starchy vegetables are significantly higher in carbohydrates than non-starchy vegetables. While vegetables are generally encouraged on keto, starchy varieties should be avoided or severely limited. These include potatoes (white and sweet potatoes), yams, corn, peas, parsnips, beets, and winter squashes like butternut and acorn squash.

Grains: Packed with Carbs

Most grains, even whole grains, are too high in carbohydrates for a ketogenic diet. Common grains to avoid include wheat, rice, oats, barley, rye, corn, quinoa, millet, amaranth, farro, and products made from these grains like bread, pasta, cereals, and crackers.

Many people find that eliminating grains is easier than expected when they discover keto-friendly bread alternatives. Numerous keto bread recipes utilize low-carb flours like almond flour and coconut flour.

Baked Goods: Sugar and Grain Bombs

Unless specifically labeled as keto-friendly, virtually all commercially baked goods are loaded with carbohydrates and sugars. Cookies, cakes, pastries, muffins, pies, brownies, donuts, and conventional desserts are primarily made with sugar and grains, making them strictly off-limits on a keto diet.

Fortunately, the keto world offers delicious recipe alternatives for almost all your favorite baked treats, allowing you to enjoy desserts without derailing your diet.

Most Packaged Foods: Hidden Carbs and Unhealthy Additives

With the exception of specifically formulated keto snacks and meals, the majority of packaged and processed foods contain ingredients that are detrimental to a ketogenic diet.

Beyond added sugars, many packaged foods also include hidden carbohydrates in the form of starches, fillers, and unhealthy additives like artificial sweeteners, flavors, colors, and preservatives. While some manufacturers are moving towards sugar alternatives like stevia or monk fruit and natural preservatives, these are still exceptions rather than the norm. Common packaged foods to minimize or avoid include crackers, chips, pretzels, granola bars, protein bars (unless keto-specific), frozen entrees, ice cream, candy, and many canned soups and sauces (always check nutrition labels for carb counts).

Low-Fat Dairy: Often Higher in Sugar

When it comes to dairy on keto, full-fat is crucial. To compensate for flavor loss when fat is removed, manufacturers often add sugars to low-fat dairy products. Even without added sugar, reducing fat alters the macronutrient profile, resulting in a higher carb-to-fat ratio, making them less suitable for keto. Full-fat dairy provides satiety and a richer taste, making it the better choice. Avoid skim milk, 1% or 2% milk, low-fat yogurt, low-fat sour cream, skim string cheese, low-fat cream cheese, and low-fat coffee creamers.

Beans and Legumes: Too High in Carbs

Beans and legumes are generally too high in carbohydrates to be included in a ketogenic meal plan. Even lentils, which are often considered a healthier legume due to their protein content, are too carb-dense for most keto dieters. This also extends to bean-based dips like hummus and black bean dip.

Cocktails and Sugary Beverages: Liquid Carbs to Avoid

Sugary beverages like soda are clearly off-limits on keto, but many other packaged drinks, including sports drinks and energy drinks, are also loaded with sugar and unhealthy ingredients. Fruit juices, pre-made iced teas, and iced coffee drinks frequently contain significant amounts of added sugar. When choosing beverages, always scrutinize the nutrition label.

Cocktails, in general, tend to be higher in sugar than simple mixed drinks like vodka soda or martinis. Avoid margaritas, bloody marys, sangria, whiskey sours, cosmos, piña coladas, and other sugar-laden cocktails on a ketogenic diet. Opt for dry wines or spirits mixed with sugar-free mixers in moderation if consuming alcohol on keto.

Takeaway: Embrace High-Fat, Low-Carb Eating

Following a high-fat, low-carb diet offers numerous potential health benefits. To fully realize the advantages of ketosis, it’s crucial to go beyond simply producing ketones and prioritize consuming high-quality, low-carb foods that are rich in healthy fats.

When grocery shopping, focus on filling your cart with whole, unprocessed food options like quality meats, non-starchy vegetables, healthy fats from avocados, nuts, and seeds, and keto-friendly dairy. Reserve packaged foods for occasional convenience and always select options specifically labeled as keto-friendly, carefully checking ingredient lists and nutrition information.
