This 13-day diet is hard, but effective, to burn off fat. After 13 days you can eat normally without putting on weight for 2 years. It is also known as The Danish Diet or The Copenhagen Diet.This is not a traditional diet where you gain the weight back at the end of the fasting period. Instead, the 13-day diet will increase your metabolism and you will maintain your weight after the diet is finished.
Just don’t freak out if in the first week after the diet you may put on a little weight. This will regulate after a while.
If you follow the 13-day diet, you will lose all excess fat, between 15 – 40 pounds (7 – 20 kg)!
The diet must be followed for 13 days. No more, no less. That’s because the 13-day diet is an extremely low caloric diet with an intake of approximately 600 calories per day.
Because this diet is unbalanced, lacking in dairy, whole grains and fruits, you may experience vitamin and mineral deficiencies and tiredness.
You’ll also feel hungry all the time and your body will be more receptive to illness.
