My mum tried the Paul Mackenna one a few months back.
Listened to the CD for about a week, found it dull and boring, stopped reading the book as (others have said) it's really just common sense, hopped on the scales at the end of the week and gained 3lbs.
CDs and book went in the bin.
IMO hypnosis is a load of bull.
you might as well tell someone they can "Dream themselves Slim".
I've always seen these types of CD's and books as being aimed at the people who think they want to lose weight, but are not really (mentally) commited to it - they just want to read the book then wake up 20lbs lighter.
Weightloss is a fight, a mental battle, between the old you's eating habits and emotional-food depandancies, and the new you's strength and force of will to change yourself into something better.
If you're not 100% mentally commited, you'll fail.
just my opinion, but a strong one
