What is a keto diet?

A keto diet is an eating plan that focuses on foods that provide a lot of healthful fats, adequate amounts of protein, and very few carbohydrates. The goal is to get more calories from fat than from carbs.

The diet works by depleting the body of its sugar reserves. As a result, it will start to break down fat for energy. This results in the production of molecules called ketones that the body uses for fuel. When the body burns fats, it can also lead to weight loss.

There are several types of the keto diet, including the Standard Ketogenic Diet and the Cyclical Ketogenic Diet.

• Ketosis
• Video course
• Safety
• Science
• For doctors.

When you eat far fewer carbs, your body begins to burn fat for fuel. This can put your body into a metabolic state called ketosis. In this state, your liver turns fat into small energy molecules called ketones, which your brain and other organs can use for energy.

Eating a keto diet lowers insulin levels, often dramatically, and naturally reduces calorie intake, which can help you access your body fat stores for energy. Many studies show significant weight loss on keto, without having to count calories. Keto diets may have other positive health effects, such as reducing blood sugar levels. In ketosis, your liver uses fat (from your body and diet) to create ketones that your brain can use for energy. Fat also fuels your muscles. 

The keto diet is a low-carb, high-fat diet. It can help the body burn more fat, reduce hunger, and reduce blood sugar levels.
