The ketogenic diet, commonly known as the keto diet, is a high-fat, moderate-protein, and very low-carbohydrate eating plan designed to shift your body’s primary energy source from glucose to fat. By drastically reducing carb intake and replacing it with healthy fats, your body enters a metabolic state called ketosis, where it burns fat for fuel instead of sugar. This process is associated with numerous health benefits, including weight loss, improved blood sugar control, reduced inflammation, and enhanced mental clarity.
Navigating the keto diet can be challenging, especially when it comes to knowing which foods to eat and which to avoid. This article will guide you through the best foods to include in your keto diet, how to structure your meals, and tips for staying successful.
How the Keto Diet Works
The keto diet works by limiting carbohydrate intake to about 20–50 grams per day, forcing your body to break down fat into ketones, which become the main energy source for your cells. This metabolic switch offers several advantages:
Weight Loss: By burning fat for energy, the body naturally reduces fat stores.
Reduced Hunger and Cravings: High-fat foods are more satiating, helping you feel full longer.
Improved Blood Sugar and Insulin Levels: Lower carb intake helps stabilize blood sugar and insulin.
Reduced Risk of Chronic Disease: The diet may lower triglycerides, LDL cholesterol, and inflammation markers.
To achieve and maintain ketosis, it’s essential to focus on nutrient-dense, whole foods and avoid processed, high-carb options.
Best Foods to Eat on the Keto Diet

2. Protein Sources
Protein is important for muscle maintenance and overall health, but should be consumed in moderation to avoid excess gluconeogenesis (conversion of protein to glucose).
