The word Ketogenic or Keto comes from ‘ketones’, which are small fuel molecules that are produced in our body by the intake of low-carb diet. A Ketogenic diet is a low-carb diet, which can help in burning the existing fat reserves adequately. The VLCKD is a European medical treatment based on a ketogenic diet. It contains the daily requirements for vitamins, minerals, trace elements, fatty acids, and proteins. Carbohydrates are under 30g/day for women and 50g/day for men.
