Sticking to a keto diet can be tricky, especially when it feels like sugary or starchy food is everywhere! I remember the first time I tried keto. The hardest part was figuring out which foods to skip, even the ones that seemed healthy. If you’re new to keto, or just need a refresher, knowing which foods to avoid can make cravings less confusing and help you stay on track for better results.
The main idea behind a keto diet is to eat foods that are very low in carbohydrates and high in healthy fats. When you cut back on carbs, your body switches to burning fat for fuel, which some people find helps with weight management and consistent energy throughout the day. The catch: carbs are in a lot of common foods, from white bread to fizzy drinks to sweet treats and at first they seem to everywhere you look!
This guide breaks down the top foods to steer clear of while on keto, shows which pantry favourites sneak in extra carbs, and gives tips for finding your way through tough situations like dinner parties or the snack aisle. With some simple swaps and a little planning, avoiding these foods is totally doable and can help you achieve the state of ketosis where your body is burning fat for fuel instead of carbohydrates.
High-Carb Foods to Avoid
Most people know bread and pasta are out on keto, but there’s a long list of unexpectedly high-carb foods that can knock you out of ketosis. Here are the main categories and why they can slow down your progress.
Refined Carbohydrates
- White Bread, packed with simple carbs and barely any fibre. Even one slice can take up a big chunk of your daily carb limit.
- Pasta (Regular and Rice Based), whether it’s regular spaghetti or rice noodles. These are made almost entirely from starch.
- Breakfast Cereals, even the ones that sound healthy (like bran or muesli) usually hide tons of added sugars and fast acting carbs.
- Pastries, Muffins, Bagels, which are often made with white flour and loads of added sugar.
On keto, it’s all about skipping these because they raise blood sugar levels fast. That blood sugar spike keeps your body from burning fat efficiently. Swapping out refined carbs for veggies like cauliflower, zucchini, or spiralised cucumber can help fill the gap if you’re craving something hearty.
Sugary Snacks and Treats
- Cakes, Biscuits, and Cookies. Even small portions usually have enough sugar and flour to max out a whole day’s worth of carbs.
- Crisps and Chips. Most crisps are made from potatoes (very high in starch) and often have added sugars in flavouring blends. Corn chips are just as carb heavy.
- Candy Bars & Sweets. Almost all popular sweets are a double whammy: sugar and starch!
These snacks are tempting but offer little nutrition and can make you feel hungry just a few minutes later. Cheese, jerky (with no added sugar), or nuts are good options for keto snacking instead. Hummus with sliced cucumber or bell pepper sticks is also an option for a crunch without the carbs.
Hidden Sugars and Beverages
Sometimes the things we drink or use to “sweeten the deal” can have just as much sugar as actual desserts, if not more. Reading labels is really important here because some products use sneaky names for sugar.
Soda and Sweetened Drinks
- Regular Sodas. A standard can of cola or lemon lime soda has around 35 to 40 grams of sugar. That equals way more than keto-friendly daily carb limits, even before you count food carbs.
- Sweetened Iced Tea and Juices. Fruit juice might sound fresh, but orange juice, apple juice, and cranberry juice are super high in sugar. Even “no added sugar” juices pack in natural sugars called fructose that work the same way in your body.
- Sports & Energy Drinks. These often contain added sugars to give you an energy boost. It’s super easy to drink half your daily carb count with just one bottle.
Alcohol
- Beer. Sometimes called “liquid bread,” beer gets most of its calories from its carb content.
- Sugary Cocktails. Mixed drinks like daiquiris, margaritas, or anything with a sweet mixer are usually made with syrups or juices full of sugar.
- Flavoured Liqueurs. These taste sweet for a reason; they often have as much sugar per ounce as gummy candy.
For keto-friendly drinks, sticking to water, sparkling water, black coffee, or unsweetened tea is safest. Dry wine or spirits (like vodka, gin, or whiskey) have minimal carbs, but it’s worth remembering that alcohol can still slow down fat loss, even without extra carbs. If you’re out at a social gathering, ordering a club soda with lime keeps things festive without the carbs.
Starches and Grains That Sneak In Carbs
Grains and starchy vegetables often fly under the radar because we expect sweets to have sugar, but not savoury foods. The reality is that even whole wheat or brown rice are too carb heavy for most keto plans.
Grains to Skip
- Rice (White, Brown, or Wild)
- Couscous, Quinoa, and Barley
- Corn, Polenta, and Tortillas
Whether a grain is “whole” or processed, it still breaks down into glucose, putting the brakes on ketosis. Swapping to cauliflower rice or cabbage as a base works well for many dishes instead.
Starchy Vegetables
- Potatoes and Sweet Potatoes
- Peas, Carrots, and Parsnips
- Butternut Squash & Pumpkin (in larger servings)
Starchy veggies aren’t “bad,” but for keto, even a small serving can push carb counts over the limit, making it harder to stay in ketosis. Low carb veggies like leafy greens, broccoli, cauliflower, and zucchini are better choices for salads, side dishes, and stir fries. Think of roasting a tray of Brussels sprouts, asparagus, and mushrooms with olive oil for a filling meal without the extra carbs.
Reading Food Labels and Spotting Hidden Carbs
Packaged foods can make sticking to keto harder, mainly because carbs are often hidden. For me, learning how to actually read a food label made a huge difference and saved me from sneaky carbs in places I never expected.
Ingredients and Tricky Marketing Terms
- Maltodextrin, Dextrose, Corn Syrup. Fancy names for sugars added to everything from sauces to deli meats.
- Honey, Agave, Maple Syrup. Sound wholesome, but they spike blood sugar like regular sugar.
Marketing words like “natural,” “organic,” or “whole grain” can make products look healthier than they are. Always check the net carbs (total carbs minus fiber and sugar alcohols) to get a clear picture. Some food manufacturers use “evaporated cane juice” or “brown rice syrup” as alternatives to plain sugar, but they act the same way in your body.
Common High-Carb Convenience Foods
- Granola Bars and Protein Bars. Most are loaded with grains and sweeteners, even the low fat versions.
- Fat Free Flavoured Yogurts. These often replace fat with extra sugar to keep the taste appealing.
- Ready Made Sauces and Salad Dressings. Ketchup, barbecue sauce, and some store bought dressings pack more sugar than people realise.
Making your own dressings or using olive oil, vinegar, and mustard is a simple, safe swap. When in doubt, the fewer unrecognisable ingredients, the better. If you have to buy packaged foods, check labels for carb content and aim for options that use stevia or monk fruit as sweeteners instead of sugar.
Handling Temptations and Social Situations
Eating out, attending parties, or dealing with family meals can be tough when you’re avoiding carbs. Over the years, I’ve figured out a few tricks that make these situations less stressful.
Easy Tips for Sticking with Keto in Tricky Spots:
- Offer to bring a keto-friendly dish when invited out. This way, you know there’s something you can enjoy without feeling left out.
- Order grilled meat or fish with a side of salad or non-starchy veggies at restaurants, and skip the fries, pasta, or breadbasket.
- Stay hydrated and keep keto snacks in your bag. Hunger makes carb temptations way harder to resist.
- If you get pressured to eat carbs, just say you feel better avoiding sugar—it keeps the conversation easy and drama free.
It’s totally normal to slip up every once in a while. The key is to refocus on your goals and make the next meal a good one, instead of feeling frustrated. Planning in advance, whether it’s packing your lunch or knowing what you’ll order ahead of time, makes it easier to stay consistent on keto even during busy weeks.
Frequently Asked Questions
Can I have fruit on keto?
Most fruits are high in sugar, especially bananas, grapes, apples, and mango. Some people include small portions of berries (like strawberries or raspberries) since they are lower in sugar, but always check your daily carb goals. Blueberries or blackberries in moderation can fit if you keep an eye on portion sizes.
Is dark chocolate keto-friendly?
Only if it’s 85% cocoa or higher, very dark chocolate can be a rare treat. Limit servings to just a few squares and check for added sugars on the label. Look for options that use stevia or erythritol instead of sugar for an occasional treat.
Are there any quick low carb snacks?
Absolutely. Some of my go to’s are cheese, almonds, macadamia nuts, cold cuts, or a hard boiled egg. Just make sure the snacks have no hidden sugars or starchy fillers. You can also try pork rinds, celery with cream cheese, or olives for quick, filling keto snacks.
Final Thoughts and Practical Tips
Sticking with keto isn’t about being perfect every single day. It’s about making smart swaps and knowing what to avoid. Reading labels, skipping processed snacks and sweetened drinks, and planning ahead make things way simpler. Once you get the hang of it, making keto-friendly choices at home, at restaurants, or when you’re busy gets a lot easier and becomes second nature.
Your Next Steps:
- Clear your pantry of high carb snacks and refined grains.
- Stock up with low carb staples like veggies, cheese, and healthy fats. Avocado, salmon, and eggs are great to keep on hand.
- Plan out a week’s worth of simple, keto-friendly meals to avoid last minute carb cravings. Try building meals around proteins with a variety of colourful low carb vegetables to keep things interesting.
