OMG!!! NO!!!!
Any program will work for anyone that puts their mind to making it work. Look, the program is not rocket science. You are on a very serious deficit while working your ass off. It is all a matter of sticking to it and being very, very careful to monitor how you feel and backing off if you feel badly. But if you back off from losing a lb a day you have to know that doesn't mean failure. That means backing off to something more reasonable. And that is good too.
