Navigating the complexities of a ketogenic (keto) diet can be challenging, especially when it comes to identifying which foods to avoid and what to replace them with. The keto diet mandates a significant reduction in carbohydrate intake while boosting the consumption of fats and moderate proteins.
To simplify this dietary transition, here are 14 foods to avoid on keto and their suitable replacements.
Bread and Grains
Bread and grains are dietary staples for many, but they are typically high in carbs, making them unsuitable for a keto diet. A single slice of whole wheat bread contains around 13 grams of carbs, while a cup of cooked rice can pack over 40 grams. These foods can quickly push you over your daily carb limit.
Instead, opt for low-carb alternatives like cloud bread or cauliflower rice. Cloud bread, made primarily from eggs and cream cheese, offers a fluffy, bread-like texture without the carbs. Cauliflower rice, which is simply grated cauliflower, can be used as a substitute in any dish that calls for rice.

Sugary Breakfast Cereals
Sugary breakfast cereals are another food group to avoid on keto. These cereals are often loaded with sugar and refined grains, leading to a high carb content. Even seemingly healthy options like granola can contain up to 40 grams of carbs per serving.
A better choice would be to start your day with a high-fat, low-carb breakfast like scrambled eggs with avocado or a chia seed pudding made with unsweetened almond milk. These options will keep you full and energized without the carb overload.
Pasta
Pasta is a beloved comfort food but is unfortunately high in carbs. A single cup of cooked spaghetti contains about 40 grams of carbs, which can easily exceed your daily limit on a keto diet. Traditional pasta is made from wheat flour, making it a high-carb food that can spike your blood sugar levels.
Fortunately, there are several keto-friendly pasta alternatives. Zucchini noodles, also known as "zoodles," are a popular choice. You can also try shirataki noodles, which are made from the konjac plant and contain virtually no carbs.

Starchy Vegetables
While vegetables are generally healthy, some starchy varieties are high in carbs and should be limited on a keto diet. Potatoes, corn, and peas are examples of starchy vegetables that can add up in carbs quickly. For instance, a medium-sized potato contains about 37 grams of carbs.
Instead, focus on non-starchy vegetables like spinach, kale, and bell peppers. These vegetables are low in carbs but high in fiber and essential nutrients, making them perfect for a keto diet. They can be used in salads, stir-fries, and as side dishes to complement your meals. For more options, see our list of 13 Low-Carb Vegetables That Are Perfect for Keto.
Sweetened Yogurt
Yogurt can be a nutritious snack, but sweetened varieties often contain added sugars, making them high in carbs. A single cup of flavored yogurt can contain up to 47 grams of carbs, which is far too much for a keto diet.
Opt for plain, unsweetened Greek yogurt instead. Greek yogurt is lower in carbs and higher in protein than regular yogurt. You can add a handful of berries or a few drops of stevia to sweeten it naturally without adding extra carbs. This way, you can enjoy the creamy texture and tangy flavor without compromising your keto goals.
Juice
Fruit juices, even those labeled as "100% natural," are high in sugar and carbs. A typical 12-ounce serving of apple juice contains about 42 grams of carbs, most of which come from sugar. These liquid carbs can quickly add up, making it difficult to stay within your daily limit.
Instead of juice, opt for low-carb drinks like water, unsweetened tea, or coffee. You can also make your own keto-friendly smoothies using ingredients like spinach, avocado, and unsweetened almond milk. These options provide hydration and nutrients without the carb load.

To emphasize the importance of choosing the right foods on a keto diet, consider this statistic: According to a study published in the "Journal of Environmental and Public Health," typical blood pH ranges from 7.2 to 7.45, and the kidneys help maintain this balance by regulating pH levels in urine, which range from 4.6 to 8.0 (Schwalfenberg, 2012). This highlights the body's intricate mechanisms to manage pH levels, which can be influenced by diet.
Additionally, nutritionist Tracy Lockwood Beckerman, RD, emphasizes the importance of moderation: “Some of the acidic foods are quite healthy, like eggs and walnuts. Eliminating these foods can cause people to become obsessive and stay away from nutrient-dense foods that we actually need,” she adds. This insight is crucial for those on restrictive diets like keto, where balance and nutrient diversity are key.
