Please be careful with this; my daughter did the diet for 1 week and ended up in the hospital with a bowel obstruction from eating so little it was not processing and passing; our bodies need all types of nutrients to operate efficiently...even the fat. A slower saner diet of good foods and excercise will yield more in the long run..remember...if it sounds too good to be true it probably is. As far as I can tell this is the same stuff from the 70's that they were pushing and they finally closed those "clinics" that were giving the shots down and sued them.....again.....please, please be careful!!!
