As the others have said the diet works, it's what you do after the diet that matters though, as I say to customers if you got big once, you can get big twice! so you have to plan for the future and deal with whatever issues there are that make you overeat whether that be boredom, comfort, stress, portion control etc etc, you must find the root cause of why you put too many calories in otherwise you will be renting a slim body for a few months.
