The ketogenic diet, commonly known as the keto diet, is characterized by its high-fat, very low-carbohydrate, and moderate-protein composition. While adopting a keto lifestyle opens up a wide array of delicious and healthy food options, understanding exactly What Are Keto Foods is crucial for success and nutritional balance, especially ensuring adequate fiber intake.
Foods perfectly suited for a keto diet include a variety of nutrient-rich choices such as fish and seafood, meats and poultry, and a spectrum of non-starchy vegetables like bell peppers, broccoli, and zucchini. Furthermore, incorporating avocados, berries in moderation, nuts and seeds, eggs, high-fat dairy products, olive oil and other healthy oils, and even high-cocoa chocolate can all be part of a well-rounded ketogenic meal plan.
Research indicates that adhering to a keto diet can be an effective strategy for fat burning while simultaneously reducing hunger sensations. It’s important to note that initial rapid weight loss may be partly attributed to water release.
However, it’s also vital to be aware that overly restrictive diets leading to rapid weight loss can pose health risks and potentially hinder long-term weight management. Studies have shown that rapid weight loss can sometimes slow down metabolism.
At ZOE, through our extensive research in nutrition and gut microbiome, we emphasize the importance of personalized nutrition. Our findings suggest that consuming the right foods tailored to your individual body can significantly enhance overall health. Many individuals following ZOE’s personalized programs have experienced positive changes in their weight.

What is the Keto Diet and How Do Keto Foods Fit In?
Initially, the keto diet was developed by medical professionals as a treatment for specific forms of childhood epilepsy. It is sometimes recommended when conventional treatments are ineffective, and for individuals using keto for epilepsy, it should always be under the strict guidance of a healthcare professional.
More recently, the keto diet has gained significant popularity as a weight loss strategy.
In a standard ketogenic diet, the general macronutrient goal is to derive 70–80% of daily calories from fat, 10–20% from protein, and only 5–10% from carbohydrates. For a 2,000-calorie daily intake, this translates to approximately 25–50 grams of carbohydrates, 150–180 grams of fat, and 50–100 grams of protein. Choosing the right keto foods is essential to meet these ratios effectively.
The fundamental mechanism of the keto diet involves shifting your body’s primary energy source. Normally, carbohydrates are converted into glucose, the body’s preferred fuel.
However, with restricted carbohydrate intake, the body begins to utilize fat for energy, converting it into compounds called ketones. This metabolic state is achieved by carefully selecting keto foods that are low in carbs and high in fats.
This process, known as ketogenesis, typically commences around 3 to 4 days after significantly reducing carbohydrate consumption. Understanding what are keto foods is crucial to successfully initiate and maintain ketogenesis.
Exploring What Are Keto Foods: Essential Categories
One potential challenge of the keto diet is ensuring adequate intake of fiber and B vitamins. This is because many foods rich in fiber and B vitamins, such as whole grains, fruits, certain vegetables, and legumes, are also relatively high in carbohydrates and thus limited on a keto diet. However, by carefully choosing from the list of what are keto foods, you can mitigate this risk.
Adequate fiber is vital for maintaining a healthy gut microbiome, the vast community of microbes residing in your digestive system. These microbes ferment fiber into beneficial compounds linked to various health advantages. Therefore, selecting fiber-rich keto foods is important for gut health.
As detailed below, certain low-carb plant-based keto foods still provide substantial fiber, including non-starchy vegetables like broccoli, cauliflower, and zucchini, as well as avocados, nuts, seeds, and berries in moderation.
Dietary fiber from plant sources does not contribute to net carbohydrate intake as it is not fully digested. “Net carbs” refer to the total carbohydrates in a food minus the fiber content. When considering what are keto foods, focusing on net carbs is crucial for staying within keto carbohydrate limits.
The following sections provide a detailed guide to the best healthy food options when considering what are keto foods for a ketogenic diet.
1. Fish and Seafood: Prime Keto Foods
Fish and shellfish are excellent choices when considering what are keto foods. Salmon, for example, is rich in omega-3 fatty acids and B vitamins while being very low in carbohydrates. Shrimp and lobster are also well-suited to a keto diet. These seafood options provide healthy fats and protein, key components of keto foods.

2. Meat and Poultry: Foundational Keto Foods
Meat and poultry are popular among those following a keto diet due to their high fat content and minimal carbohydrates, making them staples of keto foods.
However, research suggests that excessive regular consumption of meat may be linked to health issues like heart disease, type 2 diabetes, and weight gain. Therefore, moderation is key even when choosing keto foods like meat and poultry.

3. Non-Starchy Vegetables: Fiber-Rich Keto Foods
Non-starchy vegetables are vital keto foods, offering low carbohydrates combined with essential fiber.
They are also packed with micronutrients and antioxidants, crucial for overall health. Incorporating a variety of these vegetables is essential when considering what are keto foods for nutritional completeness.
Non-starchy vegetables can effectively replace high-carbohydrate foods. For instance, cauliflower can be used to make “rice,” and zucchini can be transformed into noodles. These swaps are excellent for creating keto-friendly versions of carb-heavy meals using suitable keto foods.

7. Eggs: Versatile and Keto-Approved
Eggs are a readily available and affordable source of fat and protein, while being low in carbohydrates. This makes them an excellent and versatile choice when considering what are keto foods.
Contrary to older advice limiting egg intake, current research suggests that for most people, consuming one egg daily, or up to seven eggs per week, is perfectly acceptable within a balanced diet, including a keto diet. Eggs are a foundational keto food due to their nutritional profile.
8. High-Fat Dairy Products: Keto Dairy Choices
High-fat dairy products are good sources of both protein and fat, aligning well with the macronutrient profile of keto foods.
Some dairy products offer additional health benefits. For example, yogurt can promote satiety and provide beneficial probiotics for gut health. These benefits make certain high-fat dairy options suitable keto foods.
However, conflicting research suggests balancing dairy intake with plant-based foods. Therefore, while high-fat dairy can be part of keto foods, moderation and variety are advisable.
9. Oils: Pure Fat Keto Foods
Certain oils are healthy sources of fat and contain no carbohydrates. These include olive oil, avocado oil, canola oil, nut oils, and seed oils like flax and hemp oil. These are pure fat keto foods.
Olive oil is known for its protective effects against heart disease and certain cancers, making it a particularly beneficial keto food choice. Both olives and olive oil are excellent for keto diets due to their health benefits and minimal carbohydrate content.
Oils like avocado, sunflower, and rice bran oil are more stable for high-heat cooking, offering versatility when preparing keto foods.
10. High-Cocoa Chocolate: Indulgent Keto Treat
Chocolate with a high cocoa content is a source of antioxidants, including flavanols, and may contribute to heart health. Dark chocolate can be considered a treat within keto foods.
