Ketone esters can help you achieve your athletic goals! Ketone esters are known as the "fourth fuel" alongside carbohydrates, fats, and proteins; ketone esters can provide energy when the aforementioned sources are depleted. During a few days of fasting, the body itself converts fat into ketones, so it takes a few days for the body to reach this state of ketosis. Ingesting these ketone esters can bring about the same benefits without having to adhere to a ketogenic diet.
