What to eat on a keto diet Use this simple keto food list as a guide to the foods to eat on a ketogenic diet, plus tips for planning and shopping so you stay on track.
The ketogenic diet, often called "keto," is a low-carb, high-fat diet designed to help the body enter a state called ketosis. In ketosis, the body shifts from using carbohydrates as its primary energy source to burning fat for fuel. This metabolic change can lead to various benefits, including increased energy, improved focus, and, for many, effective weight management.
The diet typically emphasizes reducing carbohydrate intake while prioritizing healthy fats and moderate protein consumption, tailoring meals to support this unique process. A well-structured food list is an invaluable tool for achieving success on the ketogenic diet.
By carefully selecting low-carb, high-fat, and moderate-protein foods, you can avoid common pitfalls like unintentionally consuming hidden carbs, which can disrupt your progress. Additionally, following a food list encourages a focus on nutrient-dense options, ensuring that your body receives essential vitamins and minerals while adapting to the diet. It can also simplify meal planning and grocery shopping, reducing stress and making your keto experience more enjoyable and sustainable in the long term.
Use this simple keto food list as a guide to the best foods to eat on a ketogenic diet, and discover some essential tips for planning and shopping to help you stay on track.
What Foods Can You Eat On A Keto Diet?
While staying mindful of macronutrient ratios is key to maintaining ketosis, focusing on a diet of whole minimally processed foods makes calculation far easier (not to mention nutritionally beneficial).
On a keto diet, you can enjoy a variety of delicious and nutrient-rich foods. Focus on low-carb vegetables like leafy greens, broccoli, and zucchini, as well as healthy fats from sources like avocados, olive oil, and nuts. Protein choices include meats, poultry, seafood, and eggs, all consumed in moderation. Dairy products such as cheese, cream, and unsweetened yogurt can be included, as long as they are low in carbs. Additionally, certain low-carb fruits like berries can be enjoyed in small amounts.

What Are The Main Foods To Avoid On A Keto Diet?
Now you have an idea of what you should be eating on a keto diet, what foods should you avoid?
Again, it quite often comes down to avoiding processed foods as they often contain so many hidden ingredients, particularly in the form of sugars and starches. But there are also whole, natural, ingredients that are not appropriate for a keto diet, such as high-sugar fruits, starchy vegetables, pulses, and most grains. There are also some surprises to look out for, such as milk for example.
Foods to Avoid on a Keto Diet

These grains and starches are high in carbohydrates and can hinder your ability to maintain ketosis, so it's best to steer clear of them while following a keto diet.
High-Carb Fruits
- Bananas
- Grapes
- Mangos
- Pineapples
- Apples
- Pears
- Cherries
- Figs
- Papayas

Some dairy products are best avoided on a keto diet because they contain a higher percentage of natural sugars or contain added sugars and carbohydrates. Opt for full-fat and unsweetened options, such as heavy cream, butter, and hard cheeses.
Alcoholic Beverages
- Beer (especially regular or lager varieties). Beer is typically high in carbohydrates, which can quickly disrupt ketosis. Many beers are made from grains that result in a significant carb content.
- Sweetened cocktails (such as margaritas, daiquiris, and pina coladas). These often contain syrups, juices, or added sugars, dramatically increasing their carbohydrate content.
- Dessert wines (like Port or Moscato). These wines tend to have higher sugar levels, which spike their carb count, making them unsuitable for a keto-friendly lifestyle.
- Flavoured liqueurs and cordials (such as Baileys, Kahlua, or Amaretto). These beverages usually include added sweeteners, contributing a significant carb load per serving.
Avoiding these alcoholic drinks on a keto diet is essential because their high carbohydrate and sugar content can interfere with the body's ability to stay in ketosis. Instead, opt for low-carb alternatives like dry wines, and pure spirits (such as vodka, gin, or whiskey), and avoid mixers high in sugar or carbs.
Sugary Foods and Beverages

These foods often contain hidden carbs or sugars, making them incompatible with the strict carbohydrate limits of the keto diet. Always check labels carefully to avoid sneaky ingredients that could kick you out of ketosis!
How To Build A Keto Grocery List
Building your personal keto grocery list can feel overwhelming at first, but with a little planning, you can stock your kitchen with delicious, low-carb essentials that make sticking to your diet much easier.
Organize a Weekly Menu
Meal planning is a powerful tool for maintaining a successful keto diet while reducing stress around food preparation. By planning ahead, you can ensure your meals stay within your desired macronutrient ratios, helping you more easily achieve and sustain ketosis. It also saves time and energy during the week, as having a clear plan eliminates last-minute decisions about what to eat.
Additionally, meal planning allows you to shop more efficiently, with a focus on keto-friendly ingredients, minimizing food waste and potentially cutting grocery costs. Perhaps most importantly, it helps you avoid temptations and stick to your dietary goals, as you’ll always have satisfying, low-carb meals ready to go.
Creating a grocery list based on your meals for the week is simple and highly effective. Start by planning your meals, including breakfast, lunch, dinner, and snacks, while keeping your keto-friendly goals in mind. Review each recipe and jot down every ingredient you’ll need, ensuring you list the exact amounts to avoid overbuying. Next, check your pantry, fridge, and freezer to see what you already have on hand, crossing those items off your list. Once your list is finalized, organize it by categories such as produce, proteins, dairy, and pantry staples. This makes grocery shopping quicker and more efficient, as you can grab everything you need from each section of the store in one go.
Focus on Whole, Unprocessed Foods
We have said it before, but it is worth repeating. Staying away from overly processed foods is good advice whatever your eating goals as they tend to come with a long list of often unnecessary ingredients.
Choosing whole, unprocessed foods on the keto diet offers numerous benefits for both your health and your overall success with the lifestyle. These foods, like fresh vegetables, high-quality meats, and healthy fats, are nutrient-dense, providing essential vitamins and minerals without the hidden sugars or carbs often found in processed options.
Additionally, whole foods are often more satisfying, which can help curb cravings and prevent overeating. By focusing on these wholesome ingredients, you’ll not only support your body’s nutritional needs but also improve the long-term sustainability of your diet.
Stock Up on Healthy Fats
Healthy fats play a crucial role in maintaining ketosis, as they serve as the primary energy source when your body shifts away from using carbohydrates for fuel. Consuming adequate amounts of fats helps your body produce ketones, which are essential for keeping you in a state of ketosis.
Additionally, healthy fats like avocados, olive oil, nuts, and seeds not only provide energy but also support brain function, hormone regulation, and overall cellular health. Including these fats in your diet ensures that you stay satiated and energized while following a ketogenic lifestyle, making it easier to maintain this metabolic state over time.
Prioritise Low-Carb Vegetables
As with any eating plan, it is important to prioritise plenty of healthy vegetables. It can be all too easy on a low-carb diet to avoid all vegetables as a source of unwanted carbohydrates. Who wouldn't rather have a slice of bread or two, rather than a side of broccoli? Whilst the occasional sneaky swap can do wonders for your mental health, your carb allowance is far better spent on nutrient-dense veggies.
Vegetables play a crucial role in ensuring you get the essential nutrients your body needs while following a keto diet. Low-carb vegetables like spinach, kale, zucchini, and cauliflower are packed with vitamins, minerals, and fibre, all while keeping your carbohydrate intake in check. They help support digestion, boost your immune system, and maintain overall health. Additionally, many vegetables are rich in antioxidants, which protect your body from oxidative stress and inflammation.
Incorporating a variety of colourful vegetables into your meals can make your keto diet more balanced, satisfying, and sustainable in the long run.
Include High-Quality Proteins
Proteins play an essential role in supporting your body's transition into ketosis and maintaining it effectively. While fats are the primary macronutrient in a keto diet, adequate protein intake ensures that your body has enough amino acids to support essential functions, such as muscle repair and hormone production.
Additionally, proteins help preserve lean muscle mass while your body burns fat for fuel. Too little protein can lead to muscle loss, while too much may interfere with ketosis. Striking the right balance in your protein consumption ensures your body functions optimally while staying in the fat-burning metabolic state of ketosis.
On a keto diet, focusing on high-quality options like grass-fed meats, free-range eggs, wild-caught fish, and plant-based protein sources ensures you’re getting the necessary nutrients without compromising your ketosis goals. These proteins not only support your overall health but also help maintain your energy levels and keep you satiated throughout the day.
Plan for Keto-Friendly Snacks
Snacks are vital in helping you stay on track with the keto diet by preventing hunger and avoiding the temptation of high-carb options. They’re a convenient way to maintain your energy levels between meals and support your progress in reaching your ketosis goals.
Well-chosen keto-friendly snacks, like nuts, seeds, cheese, or low-carb veggie sticks with dips, can curb cravings while keeping your daily carb intake in check. Additionally, having snacks readily available ensures you’re prepared even during busy days, making it easier to stick to your keto lifestyle without compromise.
The early days of keto, especially if you are transitioning from a diet laden with carbs or processed foods can be particularly challenging. You will likely be bombarded with hunger cues, real or otherwise, as your mind and your body adjust to a new lifestyle.
Consider Dairy Alternatives
Dairy does contain carbs, but the amount can vary widely depending on the type of dairy product. For those following a keto diet, it’s important to be mindful of these differences.
For example, full-fat options like heavy cream and certain cheeses, such as cheddar or mozzarella, tend to have very low carb counts, making them suitable choices. On the other hand, milk, especially regular cow’s milk, contains more carbs due to its lactose content and may need to be consumed in limited quantities or avoided altogether.
Lactose-free or low-carb dairy substitutes can be a fantastic addition to a keto diet. These alternatives, such as unsweetened almond milk, coconut milk, or dairy-free cheese, are typically much lower in carbohydrates, which makes them ideal for staying within the strict carb limits of keto. Whether you're preparing creamy sauces, smoothies, or snacks, these options provide a delicious and keto-friendly way to enhance your meals.
Check Food Labels for Hidden Carbs
It is helpful for everyone to be mindful of hidden carbs in processed foods, but it is of particular relevance to the keto diet.
Hidden carbs can sneak into your diet when you least expect it, potentially disrupting ketosis and your overall progress. Many processed or pre-packaged foods, even those labelled as "low-carb," can contain added sugars, starches, or other ingredients that may increase the total carbohydrate count.
Checking food labels carefully ensures you're aware of the exact nutritional content, including serving sizes, total carbs, and added sugars. This habit helps you make informed choices while staying within your daily carb limits, keeping your body in a state of ketosis and optimizing your keto diet success.
Identifying hidden sugars and starches in food products can feel tricky at first, but knowing what to look for makes it much easier. Start by reading the ingredient list carefully—hidden sugars often go by different names, such as maltose, dextrose, corn syrup, or honey.
Starches might be listed as modified food starch, potato starch, or tapioca. Additionally, check the total carbohydrate count on the nutrition label. Be cautious when evaluating products labeled as "natural" or "healthy," since these terms don’t always mean low-carb. Taking the time to understand these details helps you avoid unexpected carbs and stay on track with your dietary goals.
Shop in Bulk for Keto Staples
Buying keto staples in bulk can be a smart and cost-effective way to stay prepared and save money on your low-carb lifestyle. Items like almond flour, coconut flour, chia seeds, and low-carb sweeteners often have a long shelf life, making them perfect for bulk purchases. Stocking up on these essentials not only reduces frequent trips to the store but also ensures you always have the ingredients you need for keto-friendly meals and snacks.
Here at Opera Foods, we specialise in bulk buy discounts at wholesale prices on a wide range of storecupboard staples.
Avoid Temptations in the Store
Shopping can be a minefield of temptation, especially in large supermarkets that are carefully designed to encourage impulse buying. Here are a few tips to help you stay focused and avoid temptation.
- Make a List and Stick to It - Before heading to the store, plan your meals and create a shopping list of the exact ingredients you need. Sticking to your list will help you avoid veering into aisles filled with high-carb snacks and sugary treats.
- Shop After Eating - Avoid shopping on an empty stomach since hunger can make it harder to resist unhealthy choices. A full stomach helps you stay committed to picking only what you truly need.
- Avoid the Inner Aisles - Supermarkets often place processed and tempting high-carb foods within the inner aisles. Instead, focus on the perimeter where fresh produce, proteins, and dairy are usually found.
- Focus on Labels - If you do venture into the aisles, keep your eyes on the labels rather than the flashy packaging. Look closely at the nutritional information and ingredients to ensure you're staying true to your keto goals.
- Shop Mindfully - Take your time navigating the store with purpose. Avoid wandering aimlessly, as this can lead to picking up items that aren't part of your plan.
By preparing and shopping with intention, you can minimize distractions and keep your cart filled with healthy, low-carb choices.
A Final Word: Think Outside The Box
For the most part, you can't go wrong with a diet based on whole ingredients. Keeping it simple, and sticking with great produce is the way to go. Trying to replicate your carb-heavy favourites can often lead to disappointment; rather the real thing than a substandard alternative. That said, following a low-carb lifestyle can be hard, especially when you are in it for the long haul. There will be times when you want to think outside the box and satisfy certain cravings. How else would cauliflower crust pizza have become a thing?
Take our keto cereal, for example. Breakfast cereal and its associated grains (and yes, sugar) usually find their way onto the keto naughty list. Which is why we created our keto granola. For those times when you really want that cold crunch that only cereal can satisfy.
