A high-fat, low-carb diet that shifts your body into a fat-burning state called ketosis.
The ketogenic (keto) diet is a high-fat, moderate-protein, very low-carbohydrate eating plan. By drastically reducing carbs — typically to under 20–50 grams per day — your body enters a metabolic state called ketosis, where it burns fat for fuel instead of glucose.
The standard keto ratio is roughly 70% fat, 25% protein, and 5% carbs.
Keto is one of the most effective diets for fat loss. By burning fat as your primary fuel source and reducing insulin levels, many people experience significant and rapid weight loss.
The keto diet can dramatically lower blood sugar and insulin levels. Some studies show it may help manage or even reverse type 2 diabetes.
Many keto followers report improved mental clarity, sustained energy, and fewer energy crashes throughout the day once fully adapted.
The diet may reduce chronic inflammation, which is linked to heart disease, cancer, and other conditions.
High-fat meals tend to be more satiating. Many people on keto naturally eat less without feeling hungry.
The keto diet was originally developed in the 1920s to treat epilepsy in children and is still used medically for this purpose today.
