Wanted to add a note...I dont necessarily think that a fast is bad on a rare occassion...but many people get themselves into a cycle of them. When that happens, they train their bodies to conserve what is given in order to prepare for the next bout of deprivation...and THAT is something no one with weight issues needs to have their bodies trained to do. Better to accept a slower rate of loss and maintain a body that doesnt cling to every morsel that passes between your lips.
