Like all diets it asks rigor and commitment over time (nothing but the stabilization phase is 10 days lost per kilo).
3/4 The first days are the hardest, then enters a routine and appetite suppressant effect of proteins makes everyday easier gourmands.
Advantages of this system:
- Rapid weight loss
- Fat loss without muscle loss
- Renewed dynamism
Disadvantages of this scheme:
- You have to like meat or fish (or it should quickly become a hell!)
- It seems to me not very suitable for small weight loss (less than 7kg to lose)
PS: If you miss think sugar drink Cola Zero, it compensates very well this need.
