This type of diet is based on carbohydrate intake so that when the body needs fat, use what we have accumulated to produce proteins that are needed and thus lose weight.
It’s not a diet you can find on the Internet, well, you can find but it is an individualized diet, that is, to be made new for each person because if you do not get all the result could be obtained (or even you may find that you are getting fatter rather than thinner).
Find an expert who knows about this diet is not easy and a doctor, but can help, it is more likely that you try to remove the idea of such a diet because if it is a diet that celebrities do with great results, the truth is that not everybody can do it for the negative effects that will occur in the body which can be very dangerous in some people more sensitive or delicate.
If you still decide to make Internet searching on one that suits you best and I would recommend asking your doctor if any food is recommended to change to be said on that diet. It is not to scold you and you go to one of the diets, which often give them, but just to be sure of what you do.
