How Ketogenic Diet Works?

On a keto diet, you restrict carbohydrates and protein, which means you consume a diet high in fat. Insufficient carbohydrates or protein means you don't have much glucose for fuel. Your body utilizes that back-up fuel, converting the fat you eat and body fat into ketones. You're literally burning fat for fuel!

How does keto work in the body?

Ketosis is a metabolic process. When the body does not have enough glucose for energy, it burns stored fats instead. This results in a buildup of acids called ketones within the body. Some people encourage ketosis by following a diet called the ketogenic, or keto, diet.

Does a keto diet actually work?

Yes — but that answer comes with a qualifier. It takes two to three weeks on the diet to start fat burning (ketosis) in the body. So, don't expect instant results. Some studies have shown that adhering to low- or very-low-carbohydrate ketogenic diets helps people lose weight.
