i never tried but here is a site that have a warning about it [url="http://www.mayoclinic.org/healthinfo/mayoclinicdiet.html"]http://www.mayoclinic.org/healthinfo/mayoclinicdiet.html[/url]
Also it says that the diet is given to heart patients needed to lose weight fast for by-pass surgery
I am not sure if you are mentioning about this diet
I think you should try it for one week but in the long term is not going to be good for your health.
