The ketogenic (keto) diet has become a popular method for weight loss and improving metabolic health. It revolves around eating a high-fat, low-carb diet that forces your body to switch from burning carbohydrates to burning fat for fuel, a metabolic state known as ketosis. While the benefits of the keto diet are numerous, understanding exactly what you can and cannot eat is crucial to staying in ketosis and maximizing the diet’s effectiveness.

In this comprehensive guide, we’ll provide a detailed keto diet food list, covering what you should eat and avoid to stay on track. Let’s dive into the specifics, ensuring you have the knowledge to make informed food choices.

What Is the Keto Diet?

Before delving into the food list, it’s important to understand the core principles of the keto diet. The goal is to limit carbohydrate intake to 20-50 grams per day while increasing your fat intake to make up about 70-80% of your daily calories. Protein intake remains moderate, around 15-20%, to prevent the body from converting protein into glucose.

This dramatic reduction in carbs causes your body to deplete its glucose stores, leading it to produce ketones from fat and use these molecules as its primary energy source.

Now, let’s explore the detailed list of foods you can enjoy and those you should avoid to ensure you’re following the keto diet correctly.

Keto-Friendly Foods: What to Eat

1. Healthy Fats

Fat is the cornerstone of the ketogenic diet. You’ll be getting the majority of your daily calories from fats, and choosing the right types of fat is crucial for maintaining good health. Focus on consuming healthy fats, which can be broken down into:
