Starting a low-carb diet often leads to a common question: “What can I actually eat?” Simply put, a low-carb diet means you eat far fewer carbohydrates, especially from sugary foods, white bread, pasta, and high-starch vegetables. Instead, you focus on eating proteins, healthy fats, and vegetables that are low in starch. Many people follow this eating style to help with weight loss or to keep their blood sugar steady. While different low-carb plans might have their own rules, the main idea is to eat foods that are naturally low in carbs but packed with nutrients. This guide explains which foods are best, which ones are okay sometimes, and which to skip, while also giving you practical meal ideas and tips for making your low-carb diet enjoyable and simple to follow.
What Can You Eat on a Low Carb Diet?
A low-carb diet is less about restrictions and more about swapping high-carb foods for a wide range of tasty, filling options. The focus shifts from bread, pasta, and rice to proteins, good fats, and lots of colorful, non-starchy veggies.
Animal Proteins and Seafood
There are many protein choices when eating low carb. Most meats – such as beef, lamb, pork, and chicken – have almost no carbohydrates and are great foundations for meals. Eggs, which are versatile and have nearly zero carbs, make convenient choices for any meal or snack.
Seafood is also a top pick for low-carb eating. Fish like salmon, tuna, and trout, and shellfish like shrimp or crab, are very low in carbs and provide important nutrients such as vitamin B12, iodine, and omega-3 fats. If you’re buying processed meats, like certain types of bacon or jerky, check the label since some brands add sugar or starch.
Low Carb Vegetables
Vegetables, especially non-starchy ones, are encouraged on a low-carb diet. They’re full of nutrients and fiber but won’t push your carb count up too much. Leafy greens like spinach, kale, and lettuces are excellent – most of the carbs in these come from fiber. Veggies like broccoli, cauliflower, and Brussels sprouts also work well and can be cooked in many different ways.
Other good options include tomatoes, onions, eggplant, cucumbers, bell peppers, asparagus, green beans, mushrooms, and celery. Most of these have about 3 to 9 grams of carbs per 100 grams, keeping your meals fresh and satisfying.
Fruits With Lower Carb Content
Most fruits have more carbs than vegetables, but some fit fine in a low-carb diet, especially those lower in sugar. Berries – like strawberries, raspberries, and blackberries – are usually best because they have less sugar and more fiber.
Other fruits like oranges, grapefruits, apricots, lemons, kiwis, and mulberries can also be included from time to time. Avocado and olives are technically fruits, and both are prized for their healthy fats and very low carbs. Depending on your carb goal, stick to one or two servings of fruit a day.
Nuts, Seeds, and Healthy Fats
Nuts and seeds are filling, nutrient-rich, and generally low in net carbs (total carbs minus fiber). They make quick snacks or can be added to meals. Good choices are almonds, walnuts, sunflower seeds, chia seeds, pistachios, macadamia nuts, coconut, pumpkin seeds, and hazelnuts – most have 10-17 grams of carbs per 100 grams.
Healthy fats and oils are important on a low-carb diet. Butter, olive oil, avocado oil, and even lard (if you use it) have zero carbs and keep you satisfied. These work well for cooking and adding flavor to salads or vegetables.
Low Carb Dairy Products
Full-fat dairy like hard cheeses (cheddar, Swiss), heavy cream, and full-fat Greek yogurt or plain yogurt can fit well into a low-carb diet. They provide fat, protein, and calcium, usually with 2-11 grams of carbs per 100 grams.
However, flavored yogurts and some processed cheeses often sneak in sugars. Look for plain, unsweetened products, and always check the labels.
Herbs, Spices, and Condiments
Herbs and spices bring flavor to low-carb meals and have almost no carbohydrates. Items like salt, pepper, garlic, ginger, cinnamon, mustard (without added sugar), and oregano are safe choices.
For condiments, be careful. Many, like ketchup, BBQ sauce, and honey mustard, have high amounts of sugar. Use them only in small amounts and look for sugar-free options when possible. Plain mustard or homemade dressings with olive oil and vinegar are good alternatives.
Foods to Eat in Moderation on a Low Carb Diet
You don’t have to completely cut out all higher-carb foods, depending on your carb targets. Some can fit in, especially if you watch the amounts.
Legumes and Beans
Foods like lentils, black beans, chickpeas, and other beans are higher in carbs but also high in fiber and protein. If your plan isn’t super strict, or you’ve moved to a maintenance phase, small portions now and then – like a scoop in a salad or soup – can work.
Some Fruits
Fruits such as bananas, pineapples, and mangoes are higher in sugar. If you follow a stricter low-carb plan, you may want to skip these. Otherwise, occasional small servings are okay if they fit your overall carb allowance. Watch your serving size.
Whole Grains
Brown rice, oatmeal, quinoa, and other whole grains are usually limited in low-carb eating, but small portions work in less strict versions. A small serving of quinoa for dinner or a little oatmeal for breakfast can provide fiber and variety. Track your carbs to make sure you don’t go over your daily target.
Foods to Avoid on a Low Carb Diet
To stick to a low-carb diet, it’s important to limit or stay away from foods with lots of refined carbs, sugars, or processed fats. Cutting out these foods is one of the biggest changes when first starting low carb.
Grains High in Carbohydrates
Common foods like white rice, pasta, bread, tortillas, and crackers are made from refined grains and can quickly raise your blood sugar. Even small amounts can easily push you over your carb goal. It’s best to avoid these or keep them to a minimum.
Sugary Foods and Drinks
Candy, ice cream, cakes, pastries, and anything with added sugar are not good choices for a low-carb diet. The same goes for sugar-filled drinks like soda, sweet tea, sports drinks, and energy drinks – these can have more sugar in a single serving than your whole day’s allotment. Choose water, black coffee, or unsweetened tea instead.
Starchy Vegetables and Processed Foods
Vegetables like potatoes, sweet potatoes, yams, peas, and corn have more carbs than most other veggies. Limit these unless your plan allows more carbs. Also cut back on processed foods like ready-made meals, fast food, cookies, chips, and pretzels, as well as “diet” products that often add sugar to replace fat. Always read labels so you know what you’re eating.
Sample Low Carb Meal Plans
To help you get started, here are three example daily meal plans. Your exact carb needs may differ. It’s smart to talk to a doctor or dietitian to find what’s best for you. These meal plans highlight protein, healthy fats, and plenty of non-starchy vegetables.

Tips for Eating Low Carb at Restaurants
Eating out can seem tough on a low-carb diet, but with some planning, it’s very manageable. Menus may have hidden sugars and bigger portions, but you can stick to your goals if you make smart choices.
Ordering and Substitutions
- Pick main dishes based on meat or fish, grilled, baked, or broiled
- Drink plain water instead of soda, juice, or sweet tea
- Swap bread, potatoes, or rice for extra vegetables or a side salad with oil and vinegar
- Ask for sauces, dressings, or condiments on the side
- Consider setting aside half your meal to take home
Most places are fine with requests – don’t hesitate to ask for what you need.
Hidden Carbs to Watch For
- Sauces and marinades: Many contain sugar or starch
- Dressings: Some creamy or sweet dressings have added sugars – oil and vinegar are safer
- Breading and batters: Fried foods often have flour coating
- Fillers: Some meats (like meatballs or sausages) may contain breadcrumbs
- Soups/stews: These may use flour or cornstarch, or include noodles or potatoes
- “Healthy” options: Some salads include dried fruit, candied nuts, or sugary dressings
Frequently Asked Questions About Low Carb Eating
What Should I Eat on a No-Carb Day?
It’s very hard to have a day with absolutely zero carbs, as even most vegetables have small amounts. Low-carb diets usually mean eating fewer than 130g per day, while some very low-carb plans aim for 20-50g daily.
If you want to go very low for a day, stick to foods like meats, fish, eggs, and healthy fats like butter or oils. Include leafy greens and very low-carb veggies if needed. Do this only if your plan or your doctor recommends it.
What are Net Carbs vs. Total Carbs?
Total carbs include all carbs in the food – fiber, starch, and sugar. Net carbs are what your body digests and uses, calculated by subtracting the fiber (and sometimes sugar alcohols) from total carbs.
For most people, tracking net carbs is useful, since fiber doesn’t raise blood sugar and doesn’t count towards your daily limit. For whole foods: Net Carbs = Total Carbs – Fiber.
How Do I Track My Carb Intake?
- Labels: Use nutrition facts on packages. Subtract fiber from total carbs for net carbs.
- Apps and databases: Tools like MyFitnessPal or Carb Manager can help with carb counts for many foods.
- Manual log: Write down your foods and check carb counts – helps you learn portions and patterns.
- Portion awareness: Get familiar with standard serving sizes (like a medium apple has 15-20g carbs).
Regular tracking helps you spot which foods fit your plan and lets you adjust as needed.
Bottom Line: What to Eat on a Low Carb Diet
A low-carb diet is an effective way for many people to manage weight, stabilize blood sugar, and eat a healthier diet overall. Focus on real, simple foods: plenty of meat, fish, eggs, healthy fats, and non-starchy vegetables. This way, meals are filling, tasty, and support your goals.
Remember, the amount of carbs you should eat can be different for everyone. Track your intake, notice how your body responds, and adjust as needed. If you have health concerns or need to make bigger changes, check with your doctor or a registered dietitian to make sure your plan is right for you. Eating low carb can be straightforward and rewarding, letting you enjoy food while taking care of your health.
