The ketogenic diet has become one of the most popular approaches to weight loss, energy optimization, and overall health. By drastically reducing carbs and focusing on healthy fats, the keto diet flips your body’s metabolism from burning glucose to burning fat.
But while the concept of “low-carb, high-fat” sounds simple, many beginners get confused when it’s time to plan meals or go grocery shopping. What exactly can you eat on keto? And just as importantly, what should you avoid?
This ultimate food list breaks it all down—clearly and thoroughly—so you can confidently stock your kitchen, build meals, and stay in ketosis for maximum results.
The Basics: How Keto Works
The standard ketogenic diet typically follows this macro ratio:
- 70–75% fat
- 20–25% protein
- 5–10% carbohydrates (usually 20–50 grams of net carbs per day)
By limiting carbs and increasing fat, your body enters a state called ketosis, where it uses fat and ketones (produced by the liver) as its primary fuel source. This shift leads to reduced hunger, improved energy, and more effective fat burning.
Now, let’s explore exactly what to eat—and what to avoid—to stay in that fat-burning state.
✅ What to Eat on the Keto Diet
Here’s your go-to list of keto-approved foods, broken down by category:
1. Healthy Fats (Your Main Fuel Source)
Fats are the foundation of keto. Choose natural, unprocessed fats as much as possible.
Best fats for keto:
- Avocados and avocado oil
- Olive oil (extra virgin)
- Coconut oil
- MCT oil
- Grass-fed butter or ghee
- Heavy cream (full-fat)
- Lard, tallow, duck fat
- Macadamia nuts, almonds, walnuts
- Nut butters (check for added sugars)
Tip: Avoid “low-fat” products. On keto, fat is your friend.
2. Proteins (Moderate Intake)
Protein helps build and repair tissue, and it keeps you full. On keto, aim for moderate—not excessive—protein to avoid being kicked out of ketosis.
Keto-friendly protein sources:
- Grass-fed beef and lamb
- Free-range poultry (chicken, turkey, duck)
- Pork (bacon, chops, sausage—check for sugars)
- Eggs (pasture-raised if possible)
- Fatty fish (salmon, sardines, mackerel, tuna)
- Shellfish (shrimp, crab, mussels)
- Deli meats (uncured, nitrate-free, sugar-free)
Avoid breaded or processed meats unless labeled keto-friendly.
3. Low-Carb Vegetables
Vegetables provide essential vitamins, minerals, and fiber—without spiking your blood sugar.
Best keto vegetables (above-ground, non-starchy):
- Spinach, kale, arugula
- Lettuce, romaine, spring mix
- Zucchini, cucumber
- Broccoli, cauliflower
- Green beans, snow peas
- Bell peppers (in moderation)
- Mushrooms, onions, leeks (watch carbs in large amounts)
- Cabbage, Brussels sprouts
- Asparagus, celery, radishes
Tip: Stick to leafy greens and cruciferous vegetables. Avoid root vegetables unless very limited.
4. Full-Fat Dairy (If Tolerated)
Dairy can be keto-friendly if it’s full-fat and unsweetened. Some people are sensitive to dairy, so listen to your body.
Keto-friendly dairy:
- Hard cheeses (cheddar, parmesan, gouda)
- Soft cheeses (brie, mozzarella, cream cheese)
- Greek yogurt (plain, full-fat)
- Heavy cream
- Sour cream (full-fat)
Avoid: Milk (high in sugar), flavored yogurts, and low-fat dairy.
5. Nuts and Seeds
These are great for snacking and adding crunch to meals—but they’re also calorie-dense, so enjoy in moderation.
Best nuts and seeds for keto:
- Macadamia nuts
- Pecans
- Brazil nuts
- Walnuts
- Almonds
- Chia seeds
- Flaxseeds
- Pumpkin seeds
- Sunflower seeds
Limit: Cashews and pistachios (higher in carbs)
6. Berries (Occasionally)
Most fruit is too high in sugar for keto, but small portions of berries can fit.
Low-carb fruits (in moderation):
- Raspberries
- Blackberries
- Strawberries
- Blueberries (small amounts)
Pair berries with heavy cream or Greek yogurt for a keto dessert.
7. Beverages
Hydration is important on keto, especially when your body is flushing out water and electrolytes.
Keto-friendly drinks:
- Water (add lemon or salt if needed)
- Sparkling water
- Black coffee
- Bulletproof coffee (with MCT oil or butter)
- Herbal teas
- Electrolyte drinks (sugar-free)
Avoid: Sugary drinks, fruit juices, and sweetened coffees.
8. Condiments, Oils & Pantry Staples
Flavor matters. Stock your pantry with keto-safe seasonings and cooking essentials.
Keto-approved condiments & ingredients:
- Mustard
- Sugar-free ketchup or BBQ sauce
- Apple cider vinegar
- Soy sauce (or coconut aminos)
- Mayonnaise (made with avocado oil)
- Hot sauce
- Salt, pepper, garlic powder, chili flakes
- Almond flour, coconut flour
- Stevia, monk fruit, erythritol (for sweetening)
Avoid: Sauces with hidden sugars, cornstarch, or flour.
