Popularly known as the ‘Keto’ diet, this is a low-carbohydrate, moderate-protein and high-fat diet that helps burn fat more easily. Our bodies run on either glucose or fat. A low carbohydrate intake sends the body into a metabolic state known as ketosis. This is where the liver produces ketones from fat. These ketones serve as a fuel source throughout the body. This means the fat from your body and from your diet is what is used as energy, hence this is the theory behind the weight loss seen with this diet.
