15 Foods to Avoid on the Keto Diet (and What to Eat Instead)

Starting a keto diet can be tricky, especially when you’re figuring out which foods will knock you out of ketosis. The key is to keep your carb intake low and focus on healthy fats and proteins.

Here are 15 foods to avoid on a keto diet and what you can enjoy instead.

1. Potatoes

Potatoes might be versatile and delicious, but they’re loaded with carbs. A single medium potato can have more carbs than your daily allowance on keto. Instead, swap them out for mashed cauliflower or roasted turnips for a lower-carb alternative.

2. Bread

As comforting as bread is, it’s a carb-heavy no-go for keto followers. Even whole-grain varieties pack too many carbohydrates to keep you in ketosis. Opt for keto-friendly bread made from almond or coconut flour instead.

3. Rice

White, brown, or wild—rice is high in carbs and best avoided. A single cup of cooked rice can contain more than 40 grams of carbs. Try cauliflower rice as a fantastic substitute that keeps your meals low-carb.

4. Pasta

Traditional pasta is another keto diet breaker, with a single serving containing upwards of 30 grams of carbs. Fortunately, there are plenty of keto-friendly options like zucchini noodles (zoodles) or shirataki noodles. They’re light, versatile, and won’t derail your keto goals.

5. Sugary Snacks

Candy, cookies, and other sugary treats are high in carbs and sugar—a definite keto deal-breaker. Look for keto-friendly desserts sweetened with erythritol or stevia. These alternatives let you satisfy your sweet tooth without the sugar spike.

6. Bananas

Bananas are a quick and easy snack, but their natural sugars make them unsuitable for keto. A single banana can contain 20-30 grams of carbs. Stick to lower-carb fruits like raspberries, blackberries, or strawberries.

7. Milk

While nutritious, milk is rich in lactose, a natural sugar that can add up quickly. One cup of whole milk contains about 12 grams of carbs. Unsweetened almond or coconut milk makes a great keto-friendly substitute.

8. Beans

Beans and legumes are high in carbs despite their reputation as healthy plant-based proteins. A cup of cooked beans can contain up to 40 grams of carbs. Replace them with lower-carb options like tofu or tempeh for your protein needs.

9. Beer

Beer’s high carb content makes it a poor choice for keto enthusiasts. A single pint can contain over 20 grams of carbs. Opt for low-carb alcoholic beverages like dry wine or spirits mixed with soda water.

10. Sweetened Yogurt

Flavored yogurts often come with added sugars that can sneakily increase your carb intake. Some varieties contain as much as 20 grams of sugar per serving. Choose plain, full-fat Greek yogurt and sweeten it yourself with a few berries.

11. Snack Foods

Chips, pretzels, and crackers are typically high in carbs and low in nutritional value. Swap them out for keto-friendly snacks like cheese crisps, pork rinds, or a handful of nuts. These options are just as satisfying and won’t mess with your carb count.
