Starting keto usually comes down to one problem: you know sugar and bread are out, but nobody tells you what to actually put in your cart. This list fixes that. Every category below comes with approximate net carbs per serving, so you're not guessing whether something fits.
What "Low Carb" Actually Means
Not all carbs count the same way on keto. What matters is net carbs — total carbohydrates minus fiber, since fiber isn't digested and doesn't raise blood sugar.
Here's the math: a food with 10g total carbs and 6g fiber has 4g net carbs. That's why a cup of raspberries fits comfortably into a low-carb day, but a cup of white rice doesn't, even though both technically contain carbohydrates.
Most beginners aim for somewhere between 20 and 50 grams of net carbs a day. That range isn't a rule carved in stone — it's a common starting point people adjust once they see how their body responds.
Sugar alcohols — erythritol, xylitol, and similar — are sometimes subtracted from carb counts on packaging too. Worth knowing: they don't affect everyone the same way, and some people notice a smaller blood sugar response than the label math suggests.
The Low Carb Food List, by Category
Proteins
Meat, poultry, fish, and eggs carry essentially zero carbs on their own. Where carbs sneak in is the coating or marinade — plain grilled chicken is 0g net carbs; the same chicken breaded and fried is a different food entirely.
- Beef, pork, lamb: 0g net carbs
- Chicken, turkey: 0g net carbs
- Fish and shellfish: 0g net carbs
- Eggs: under 1g net carbs each
Healthy Fats & Oils
Fat isn't just tolerated on keto. It replaces the energy you'd normally pull from carbohydrates and keeps you full between meals.
- Olive oil, avocado oil, coconut oil: 0g net carbs
- Butter, ghee: 0g net carbs
- Avocado: about 2g net carbs per 100g (mostly fiber)
- Mayonnaise (check the label — some brands add sugar): 0–1g net carbs per tablespoon
Low-Carb Vegetables
This is the category beginners underestimate. Most non-starchy vegetables leave plenty of room in a 20–50g day.
- Spinach, lettuce, arugula: ~1g net carbs per 100g
- Zucchini, cucumber: ~2–3g net carbs per 100g
- Broccoli, cauliflower: ~3–4g net carbs per 100g
- Bell peppers: ~3–6g net carbs per 100g, depending on color
- Asparagus, green beans: ~2–5g net carbs per 100g
- Mushrooms: ~2g net carbs per 100g
Dairy & Dairy Alternatives
Dairy is mostly keto-friendly, but portion matters more here than people expect — the carbs in a splash of cream and a full glass of milk aren't in the same universe.
- Hard cheeses (cheddar, parmesan, mozzarella): under 1g net carbs per ounce
- Heavy cream: under 1g net carbs per tablespoon
- Sour cream: ~1g net carbs per tablespoon
- Plain full-fat Greek yogurt: ~4–5g net carbs per 100g
- Unsweetened almond milk: ~1g net carbs per cup
Nuts & Seeds
Easy to snack on, easy to overeat. A handful is a serving; a bowl isn't.
- Almonds, walnuts: ~2g net carbs per ounce
- Macadamia nuts: ~1–2g net carbs per ounce
- Chia seeds: ~1g net carbs per tablespoon (fiber does the heavy lifting)
- Flaxseed: close to 0g net carbs per tablespoon
Fruits (the short list)
Most fruit is too sugar-dense for a strict keto day. Berries are the exception, thanks to their fiber-to-sugar ratio.
- Raspberries: ~3g net carbs per half cup
- Blackberries: ~3–4g net carbs per half cup
- Strawberries: ~5g net carbs per half cup, sliced
Beverages
- Water, black coffee, unsweetened tea: 0g net carbs
- Bone broth: 0g net carbs
- Unsweetened almond or coconut milk: ~1g net carbs per cup
Common Beginner Mistakes (Carb Traps)
A few foods look safe and aren't:
- Flavored yogurt and "light" products. Removing fat often means adding sugar to compensate.
- Bottled sauces and dressings. Ketchup, barbecue sauce, and many salad dressings hide added sugar.
- Packaged "keto" snacks. Some genuinely fit; others use sugar alcohols in amounts that still add up. Read the label, not the front-of-box claim.
- Flavored coffee creamers and "low-carb" protein bars/shakes. Marketing language on the front doesn't always match the carb count on the back.
How to Build a Simple Meal From This List
The framework is straightforward: protein + fat + low-carb vegetable.
- Grilled chicken thighs, sautéed spinach, and a spoon of olive oil
- Salmon, roasted broccoli, and butter
- Eggs scrambled in butter with mushrooms and cheddar
None of these need special ingredients — just picking from categories that are already carb-light.
Foods to Limit or Avoid
- Bread, pasta, rice, and other grains
- Sugar, honey, and syrup
- Most legumes (beans, lentils, chickpeas)
- Starchy root vegetables (potatoes, corn)
- High-sugar fruit (bananas, grapes, mangoes)
FAQs
How many carbs per day should a beginner eat on keto?
Most people starting aim for 20–50 grams of net carbs a day, then adjust based on how they feel and respond.
Can I eat fruit on keto?
Berries — raspberries, blackberries, strawberries — fit in moderate amounts. Most other fruit is too high in sugar for a typical keto carb budget.
Are beans and lentils low carb?
No. Legumes contain enough carbohydrate that even a modest serving can take up a meaningful chunk of a daily carb allowance.
Is eating this much fat actually healthy?
On keto, fat replaces the energy source carbohydrates normally provide — it's functional here, not incidental.
What can I snack on?
Cheese, a small handful of nuts, hard-boiled eggs, or cucumber slices with guacamole all fit comfortably into a low-carb day.
Do I need to count total carbs or net carbs?
Net carbs — total carbs minus fiber — is the number most keto guidelines are built around.
What's the difference between "low carb" and "keto"?
Low carb is a spectrum; keto is a specific, stricter version of it aimed at a daily net-carb range low enough to shift the body's main fuel source toward fat. All keto foods are low carb, but not all low-carb eating is strict enough to be keto.
Getting the food list right is most of the battle in the first few weeks. Once you know which categories to shop from, the rest of keto is mostly repetition.
